1.0 INTRODUCTION 

Future year emission inventory projections are essential to evaluating the future benefits 

of air quality control measures and supporting various modeling analyses. Eastern Research 

Group, Inc. (ERG) was contracted by Western Governors Association (WGA) to develop 

emissions inventory projections for Mexico’s National Institute of Ecology (INE – Instituto 

Nacional de Ecología) based upon the 1999 Mexico National Emissions Inventory (MNEI). In 

addition, the projection inventory process supports the fourth phase of the Integrated 

Environmental Strategies (IES) Program sponsored by the U.S. Environmental Protection 

Agency (U.S. EPA) and the National Renewable Energy Laboratory (NREL) to evaluate the cobenefits of air quality control measures in Mexico at the national level. 

The 1999 MNEI, previously developed by ERG, includes emission estimates for point, 

area, on-road, nonroad, and natural source types, at the municipality-level for the year 1999. 

Under this current project, ERG projected the 1999 emissions estimates for point, area, on-road, 

and nonroad sources to the future years of 2008, 2012, and 2030. The projected emission 

inventory was developed at the municipality-level. Also, ERG analyzed emission impacts in 

Mexico from three control scenarios developed in consultation with INE. The remainder of this 

report discusses the results and findings of this study. 

The remainder of this report is organized as follows: 

• Section 2.0 – Scope. This section provides a brief outline of the scope of this current 

project. 

• Section 3.0 – New Municipality Adjustments. This section describes the adjustments 

made to the 1999 MNEI to account for 11 new Mexican municipalities that were 

created since 1999. 

• Section 4.0 – Methodology. This section describes the methodology used to develop 

growth factors for point sources, area sources, on-road motor vehicles, and nonroad 

mobile sources. 

• Section 5.0 – Control Scenarios. This section presents the control scenarios that were 

developed and applied to the future year emissions. 

• Section 6.0 – Harmonization with Greenhouse Gas Emission Inventories. This 

section describes how the projections were harmonized (i.e., standardized, or having 
Mexico Projections

increased comparability and/or convergence) with existing greenhouse gas emission 

inventories in Mexico, as well as with other inventories that are currently under 

development in Mexico. 

• Section 7.0 – References. This section presents references for all documents, reports, 

data, and personal communication used to develop the future year emissions. 

• Tables. All tables are presented sequentially at the end of the report, rather than in 

the body of the text. 

2.0 SCOPE 

Since the future year emission inventory projections are based upon the 1999 MNEI, the 

scope of the future year projections is similar to the MNEI, and includes the following 

characteristics: 

• Source types – Point sources, area sources, on-road motor vehicles, and nonroad 

mobile sources. Natural sources (i.e., biogenic and volcanic sources) are not part of 

the scope of the future year projections. 

• Pollutants – Nitrogen oxides (NOx), sulfur dioxide (SO2), volatile organic compounds 

(VOC), carbon monoxide (CO), particulate matter with an aerodynamic diameter of 

10 micrometers (μm) or less (PM10), particulate matter with an aerodynamic diameter 

of 2.5 μm or less (PM2.5), and ammonia (NH3). 

• Spatial aggregation – Municipality-level for the 2,454 municipalities in Mexico. In 

the 1999 MNEI, there were 2,443 municipalities. Since 1999, 11 additional 

municipalities were formed in Mexico, so adjustments were made to include these 11 

additional municipalities. 

• Reported units – Megagrams (Mg) per year (i.e., 1,000 kilograms [kg] or 1 metric 

ton). 

• Projected emission results are provided in spreadsheets, U.S. EPA Emissions 

Inventory Format (NIF) 3.0, and SMOKE/IDA (modeling) files. 

3.0 NEW MUNICIPALITY ADJUSTMENTS 

 Prior to projecting the 1999 Mexico National Emissions Inventory (MNEI) forward to 

2008, 2012, and 2030, it was necessary to adjust the baseline municipality-level emissions to 

account for municipality realignments since 1999. The 1999 MNEI contained a total of 2,443 

municipalities for the entire country (ERG, 2006). However, the national municipality-level 

population projections that were provided by the National Council on Population (CONAPO – 
Mexico Projections 

Final, January 9, 2009

3

Consejo Nacional de Población) indicated that there were a total of 2,454 municipalities as of 

2005 (CONAPO, 2008). The 11 new municipalities were formed in the states of Guerrero, 

México, Veracruz, and Zacatecas. Seven new municipalities were formed by the division of an 

existing municipality; four new municipalities were formed by the reorganization of multiple 

existing municipalities. Table 1 (at the back of this document) lists the new municipalities and 

their associated municipality codes. 

Emissions from the 1999 MNEI older municipalities listed in Table 1 were allocated to 

the new municipalities. If this allocation had not been performed, then these 11 new 

municipalities would have zero emissions in the 1999 baseline inventory, as well as the future 

year projected inventories. 

The emissions allocation for area sources, on-road motor vehicles, and nonroad mobile 

sources was based upon the ratio of 2005 population estimates. For example, Iliatenco 

(Guerrero) was formed from the municipalities of Malinaltepec and San Luis Acatlán. The 2005 

populations of these municipalities were as follows: Malinaltepec – 27,231; San Luis Acatlán – 

41,917; Iliatenco – 9,762; and three municipality total – 78,910. The calculated ratios were then: 

Malinaltepec – 0.3451 (i.e., 27,231/78,910); San Luis Acatlán – 0.5312; and Iliatenco – 0.1237. 

For point source emissions, Geographic Information System (GIS) was used to plot the 

point source locations to determine if any were located within the municipalities that were split 

to form new municipalities. It was confirmed that no reallocation of point source emissions was 

needed because none of the point sources were within the 11 new municipalities. 

4.0 METHODOLOGY 

This section provides the general methodology used for developing future year growth 

projections (Section 4.1), as well as the source-type specific methodologies (Section 4.2). 

4.1 General Projections Methodology 

At the most basic level, future year projected emissions are estimated by multiplying base 

year emissions by a projection factor as shown in the following equation:

Efy = Eby × P 
Mexico Projections 

Final, January 9, 2009

4

Where: Efy = projected future year emissions 

 Eby = base year emissions 

 P = projection factor 

A projection factor of 1.0 represents a situation of no growth (i.e., projected emissions are equal 

to base year emissions). A projection factor greater than 1.0 represents increasing emissions, 

while a projection factor less than 1.0 represents decreasing emissions. 

However, in practice, the projection factor is typically disaggregated into two 

components: a growth factor and a control factor. This results in the following modified 

equation: 

Efy = Eby × G × C 

Where: Efy = projected future year emissions 

 Eby = base year emissions 

 G = growth factor 

 C = control factor 

The growth factor is often derived by projections of surrogates (i.e., population, 

economic growth, land development, etc.). For instance, a 15 percent projected growth rate for 

population could be used to estimate a growth factor of 1.15. The control factor is typically 

derived from expected future laws, regulations, policies, industry trends, or control 

implementation. For example, the expected implementation of a control device with 40 percent 

lower emissions across an entire industrial sector could be used to estimate a control factor of 

0.60 (i.e., 40 percent control corresponds to controlled emissions that are 60 percent of 

uncontrolled emissions). 

4.2 Source Type-Specific Projections Methodology 

For the purposes of this project, baseline growth projections for 2008, 2012, and 2030 

were developed initially assuming no future controls. The methodologies used for these baseline 

growth projections are described below; the methodologies used to incorporate control scenarios 

are provided in Section 5.0. Ideally, the development of growth factors would be conducted at 

the facility- or process-level. However, information concerning expected future year conditions 

was typically limited due to the lack of data. As a result, facility- or process-level growth factors 

were not developed; instead, national- and regional-level growth factors were developed.

After the baseline growth projections were developed, then three control scenarios were 

applied to the baseline growth projections. These control scenarios were developed in 

conjunction with INE staff. 

4.2.1 Point Source Projections 

The 1999 MNEI point source emissions were projected to 2008, 2012, and 2030. The 

first step was to classify all of the 1999 MNEI point sources into one of six groups based upon 3-

digit North American Industry Classification System (NAICS) codes. The assignment of the 3-

digit NAICS codes is presented in Table 2. The six groups were: 

• Electricity generating units (EGUs) 

• Refineries and other petroleum-related sources 

• Primary metals 

• Manufacturing industries 

• Miscellaneous industries 

• Services 

The methodology used to develop growth factors for each of these point source groups is 

described below. 

Growth Factors – EGUs 

The growth factors for EGUs were developed from historical fuel use statistics and fuel 

use projections. The actual fuel consumption by the EGU sector for 1999 was obtained from the 

1999 Mexico NEI fuel balance (ERG, 2003a). Projections of fuel used for electricity generation 

for 2008, 2012, and 2030 were generated using the Long-Range Energy Alternatives Planning 

System (LEAP) (Cuatecontzi, 2008). These projected fuel consumption data (in petajoules [PJ]) 

are shown in Table 3. The growth factors for each future year were estimated by calculating the 

ratio of the projected future year demand data relative to the actual 1999 fuel combustion. 

Fuel-specific growth factors were only developed for natural gas, combustóleo (i.e., 

residual fuel oil), and coal. The EGUs contained in the 1999 MNEI were assigned a fuel type 

based upon power plant information from the Commission for Environmental Cooperation of 
Mexico Projections 

Final, January 9, 2009

North America (CEC) (CEC, 2004). Based upon the CEC power plant information, fuel types 

were assigned to 41 of 73 EGUs. For the remaining 32 EGUs were assigned either natural gas or 

combustóleo based upon comparative SO2 emissions relative to NOx emissions at the facility 

level (i.e., EGUs with low SO2 emissions were assigned to natural gas, while EGUs with high 

SO2 emissions were assigned to combustóleo. 

Growth Factors – Refineries and Other Petroleum-Related Sources 

The growth factors for refineries and other petroleum-related sources were developed 

from historical crude oil production statistics and future production projections. 

The 1999 crude oil production was obtained from an analysis of the Department of 

Energy (DOE)/Energy Information Administration’s (EIA) International Energy Outlook

(Blanchard, 2001); this study indicated a daily total crude production of 2.87 million barrels for 

Mexico in 1999. Future year crude production forecast data were obtained from the 

Organization of the Petroleum Exporting Countries’ (OPEC) World Oil Outlook (OPEC, 2007). 

The crude oil production data used to develop projection factors are presented in Table 4. These 

data indicate a decrease in crude production for Mexico in future years (e.g., the crude 

production in 2030 is almost equal to that in 1999). 

Growth Factors – Primary Metals 

The growth factors for primary metals facilities were based upon historic copper, lead, 

and zinc production data in Mexico. Historic Mexican copper, lead, and zinc production data 

from 1990 to 2006 were obtained from the United States Geological Survey (USGS) Mineral 

Resources Program (USGS, 2008). Aggregated copper, lead, and zinc statistics for primary 

refined metal were used to develop a linear regression equation to predict annual primary metal 

production for the years 2008, 2012, and 2030. Growth factors were then developed by dividing 

the projected future year primary metal production by the actual 1999 primary metal production. 

Growth Factors – Manufacturing Industries and Miscellaneous Industries 

The growth factors for manufacturing industries, as well as miscellaneous industries were 

based upon Mexican gross domestic product (GDP). An annual GDP rate of 3.5 percent has 
Mexico Projections 

Final, January 9, 2009

7

been recently used for various environmental and economic studies; this annual growth rate was 

adopted for projecting these sectors (Galindo Paliza, 2008). 

Growth Factors – Services 

The growth factors for service sector point sources were based upon municipality-level 

population estimates for the time period from 2005 to 2030 (CONAPO, 2008). As shown in 

Table 2, services category point sources include repair and maintenance shops; dry cleaners; 

wastewater treatment plants; and government and public service facilities such as hospitals, 

schools, and office buildings. The growth of these types of point sources can largely be 

attributed to growth in population. Therefore, municipality-level population was used as a 

surrogate to project emissions from these sources. 

Results 

The overall projected baseline point source emission totals are presented in Table 5; the 

baseline point source emission totals are also disaggregated by group in Table 6. The 

disaggregated emissions are also presented on a percentage basis in Table 7. 

Table 5 indicates an approximately three-fold increase in baseline NOx emissions from 

1999 to 2030. Most of this increase can be attributed to the EGU sources, where the baseline 

NOx emissions in 2030 increased by 279 percent from the 1999 levels. Similarly, the 

manufacturing sector saw a three-fold increase in 2030 NOx emissions compared to the 1999 

levels. However, the 2030 NOx emissions in the refineries sector was nearly unchanged relative 

to the 1999 NOx emissions. 

According to Table 5, baseline SO2 emissions in the year 2030 increased by a little over 

25 percent from 1999. Of the total SO2 emissions from the EGU sector in 1999, power plants 

fired with combustóleo (residual fuel oil) contributed approximately 75 percent of the emissions. 

As Mexico is moving away from use of residual fuel oil in power plants, SO2 emissions in 2030 

from residual fuel fired power plants dropped by almost 87 percent. On the other hand, SO2

emissions from natural gas fired power plants experienced an increase of 30 percent and those 

from coal fired power plants increased by approximately 279 percent. Also, SO2 emissions in 

the year 2030 from the manufacturing sector increased almost three-fold from the 1999 levels.

Over 50 percent of the VOC emissions from point sources in 1999 were from refineries. 

The 2030 emissions were relatively unchanged compared to the 1999 emissions. The increase in 

VOC emissions from 1999 levels to 2030 levels can be attributed to manufacturing industries 

with 2030 VOC emissions increasing by almost 200 percent from their 1999 levels. 

Approximately 72 percent of the total point source CO emissions in 1999 originate from 

refineries and manufacturing. While the emissions from refineries stayed the same, emissions 

from manufacturing are projected to increase by approximately 200 percent. Manufacturing 

contributes to slightly less than half of the total CO increase from 1999 to the year 2030. EGUs 

are responsible for a similar increase in CO emissions. 

A majority of PM10 emissions (i.e., 44 percent) and PM2.5 emissions (i.e., 41 percent) in 

1999 are from manufacturing. By 2030, particulate emissions from these sources are projected 

to increase by approximately 190 percent compared to their 1999 levels. Out of the total 

increase in particulate emissions, manufacturing sources contribute approximately 73 percent of 

the PM10 increase and 70 percent of the PM2.5 emissions increase. In addition, EGUs contribute 

approximately 11 percent of the PM10 increase and 26 percent of the PM2.5 increase. Particulate 

emissions in the year 2030 from refineries stays almost the same as their 1999 levels. 

4.2.2 Area Source Projections 

The 1999 MNEI area source emissions were projected to 2008, 2012, and 2030 using 

various growth surrogates, as shown in Table 8. A majority of the area source categories were 

projected to 2008, 2012, and 2030 using population and fuel use surrogates. The growth factor 

development methodologies for each of the surrogates shown in Table 8. 

Growth Factors – Population 

A population surrogate was used to project emissions growth for the 14 area source 

categories shown in Table 8. Municipality-level population estimates for Mexico for the time 

period 2005-2030 were obtained from CONAPO (CONAPO, 2008); 1999 municipality-level 

population data were obtained from the 1999 MNEI (ERG, 2006). Municipality-level 

population growth factors were calculated by dividing 2008, 2012, and 2030 population by 1999 

population.

Growth Factors – Fuel Use 

Fuel use surrogates were used to project emissions growth for fuel combustion of six 

different fuels (i.e., distillate, residual, natural gas, LPG, kerosene, and wood), as well as 

commercial marine vessels and the distribution of gasoline and LPG. Future year fuel use 

projections were generated using LEAP (Cuatecontzi, 2008). The projection data consisted of 

actual energy demand data for the years 1999 through 2006 and forecasted energy demand data 

for the years 2007 through 2030. These data were available by sector (e.g., industrial, 

commercial, residential, agricultural, transportation, etc.) and by fuel type. Sector- and fuelspecific growth factors were calculated by dividing the future year energy demand (in petajoules 

[PJ]) by 1999 energy demand (in PJ). 

LPG demand for all sectors was summed together to estimate the growth factors for the 

LPG distribution source category. Gasoline demand for the transportation sector was used to 

calculate growth factors for the gasoline distribution source category. 

Growth Factors – Gross Domestic Product (GDP) 

Mexican GDP was used as a growth surrogate to project 1999 emissions to 2008, 2012, 

and 2030, for three area source categories (i.e., locomotives, industrial surface coatings, and 

degreasing). As discussed for point sources, a GDP rate of 3.5 percent has been recently used for 

various environmental and economic studies (Galindo Paliza, 2008). This annual growth rate 

was used for projecting these three source categories. 

A slightly different method was used for locomotives. The annual growth rate of 3.5 

percent was used to develop the 2008 and 2012 growth factors; however, no growth was 

assumed to occur after 2012 (i.e., the 2030 growth factor was assumed to be the same as the 

2012 growth factor) (López Villegas, 2008a). 

Growth Factors – Planted Acreage 

Historical planted acreage by state was used to develop growth factors for the pesticide 

application, agricultural tilling, fertilizer application, and agricultural burning. State-level 

historical planted acreage from 1980 to 2006 was obtained from the Secretariat of Agriculture, 

Livestock, Rural Development, Fisheries, and Food (SAGARPA – Secretaría de Agricultura, 
Mexico Projections 

Final, January 9, 2009

10

Ganadería, Desarrollo Rural, Pesca y Alimentación) (SAGARPA, 2008a). Using these data, a 

long-term annual average planted acreage was calculated for each state. Long-term annual 

average planted acreage was used rather than linear regressions because the state-level year-toyear statistics appeared to have some reporting gaps and tend to be very erratic. It was then 

assumed that the planted acreage in 2008, 2012, and 2030 will be equal to the long-term annual 

average planted acreage. Growth factors were developed by dividing the long-term annual 

average planted acreage by the state-level 1999 planted acreage. In some cases, the growth 

factor was less than 1.0 (i.e., the long-term annual average planted acreage was less than the 

1999 planted acreage). For agricultural burning, only historical averages of wheat and sugarcane 

planted acreages were used to derive growth factors. Burning of sugarcane prior to harvest is a 

common agricultural practice throughout the world in order to remove leafy trash. Post-harvest 

burning of wheat is commonly practiced to eliminate wheat stubble; recent inventory efforts in 

San Luis Río Colorado, Sonora and Mexicali, Baja California indicate that the practice is fairly 

common in Mexico (ENVIRON and ERG, 2007; ERG, 2008). 

Growth Factors – Livestock Population 

Historical livestock population by state was used to develop growth factors for the 

livestock ammonia and beef cattle feedlots. State-level livestock populations from 1996 to 2005 

were obtained from SAGARPA for the following seven livestock categories: beef cows, dairy 

cows, pigs, sheep, horses, chickens, and turkeys (SAGARPA, 2008b). Using these data, 

historical average populations were calculated for each livestock category for each state. It was 

then assumed that the livestock populations in 2008, 2012, and 2030 would be equal to the 

historical average populations. Growth factors were developed by dividing the historical average 

populations by the state-level 1999 livestock populations. In some cases, the growth factor was 

less than 1.0 (i.e., the historical average populations were less than the 1999 livestock 

populations). The overall 1999 MNEI emissions for livestock ammonia were split into emissions 

by livestock type, and growth factors were applied to each livestock type to project emissions to 

2008, 2012, and 2030.

Growth Factor – Burned Forest Acreage 

Historical data on burned forest acreage by state were used to develop growth factors for 

wildfires. State-level burned forest acreage from 1970 to 2005 was obtained from the National 

Forest Commission (CONAFOR – Comisión Nacional Forestal) (CONAFOR, 2008). Historical 

burned forest acreage was calculated at the state level and was assumed to be equal to the burned 

forest acreage in 2008, 2012, and 2030. Growth factors were developed by dividing the statelevel historical burned forest acreage by the 1999 burned forest acreage. 

Growth Factor – Border Crossing Vehicle Traffic 

Historical border crossing vehicle traffic data were used to develop growth factors for 

border crossings. Historical traffic data from the year 1995 to 2007 (including buses, trucks, and 

personal vehicles) were obtained from the U.S. Bureau of Transportation Statistics (BTS) (BTS, 

2008). These data were used to develop a linear regression equation to predict the total vehicular 

traffic at border crossings in 2008, 2012, and 2030. After predicting the annual traffic counts for 

2008, 2012, and 2030, growth factors were developed by dividing the future year vehicular 

traffic by 1999 vehicular traffic. Traffic data were limited to border crossing traffic for vehicles 

crossing from Mexico into the U.S. Emission estimates for vehicles crossing from the U.S. into 

Mexico were not estimated as part of the 1999 MNEI because of insignificant wait times. Also, 

the 1999 MNEI did not include emissions for border crossings at Mexico’s borders with 

Guatemala and Belize because of data unavailability. 

Growth Factor – Aircraft Passenger Volume 

Annual air passenger traffic data were used to develop growth factors for aircraft 

emissions. Total passenger volume data (both domestic and international) from January 2001 

through August 2008 were obtained from Grupo Aeroportuario del Centro Norte, S.A.B. de C.V. 

(OMA) for 13 airports in north and central Mexico (OMA, 2008). Although there are more than 

13 airports located in Mexico, it was assumed that the 13 OMA airports reasonably 

approximated the national level of aircraft activity. For the year 2008, the eight months of data 

from January to August were extrapolated to obtain an annual estimate for 2008. After 

completing the extrapolation of the 2008 annual estimate, the data from 2001 to 2008 were used 

to develop a linear regression equation to predict annual total passenger volume for 2012 and 
Mexico Projections 

Final, January 9, 2009

12

2020. Once the annual air passenger volumes for the years 2008, 2012, and 2030 was obtained, 

growth factors were developed by dividing the future year air passenger volume by 1999 air 

passenger volume. 

Growth Factors – Public Wastewater Treatment 

Historical public treated wastewater quantities were used to develop growth factors for 

wastewater treatment. Annual treated wastewater quantities from 1999 to 2006, as well as 

planned treatment rate increases until 2012, were obtained from the National Water Commission 

(CNA, 2007). Due to the unavailability of data, it was assumed that 2030 treatment quantities 

would be equal to 2012. The 2008 and 2012 planning values were divided by the 1999 actual 

treated quantities to obtain the growth factors. 

Results

The projected baseline area source emission totals are summarized in Table 9, along with 

the initial 1999 area source emission totals. Baseline area source emissions disaggregated by 

SCC are presented in Tables 10 through 13. 

As can be seen from the tables, SO2 emissions in 2030 are projected to decrease by 

almost 88 percent compared to the 1999 base year emissions. This decrease in SO2 emissions 

can be primarily attributed to changes in the industrial and commercial residual combustion 

category. SO2 emissions from residual fuel combustion in 1999 were approximately 56,000 

Mg/year. The energy demand projections from LEAP (Cuatecontzi, 2008) indicated that there 

will be no residual fuel combustion in the commercial sector after 2002; therefore, SO2

emissions from commercial residual fuel combustion in 2008, 2012, and 2030 were set to zero. 

Similarly, the energy demand data also indicated that emissions from industrial residual fuel 

combustion are projected to drop to 10 percent of 1999 levels. 

The 2030 NOx emissions, on the other hand, are projected to increase to nearly 200 

percent of their 1999 level. Most of this increase can be attributed to the commercial marine 

vessel and LPG combustion source categories. The NOx emissions from commercial marine 

vessels are projected to increase from approximately 76,000 Mg/yr in 1999 to almost 282,000 

Mg/yr in 2030. The energy demand projections from LEAP (Cuatecontzi, 2008) indicated a 
Mexico Projections 

Final, January 9, 2009

threefold increase in commercial marine diesel use in 2030 compared to 1999 levels. Also, NOx

emissions for all the LPG combustion categories (i.e., industrial, commercial, residential, 

transportation, and agriculture) are projected to grow from 72,750 Mg/yr in 1999 to 384,230 

Mg/yr in 2030. 

Tables 9 through 13 show a steady increase in VOC emission levels from 1999 to 2030. 

In 1999, approximately half the VOC emissions are from the solvent evaporation categories 

(e.g., industrial surface coatings, architectural surface coatings, degreasing, consumer solvent 

usage, etc.). The growth factors for these categories were based upon either population or GDP 

and the VOC growth tends to mirror these two growth factors. 

Like VOC, the CO emission estimates also indicate a steady increase from the 1999 

levels. However, it should be noted that almost all of the CO increase can be attributed to 

growth in transportation LPG combustion. The 1999 CO emissions from transportation LPG 

combustion are approximately 279,000 Mg/yr, corresponding to 11 percent of the total area 

source CO emissions. In 2030, the CO emissions for the same category projected to be 

2,167,194 Mg/yr (i.e., an emissions increase of a factor of 8). This is due to an expected major 

increase in LPG usage by transportation sources, from 35.3 petajoules (PJ) in 1999 to 274.7 PJ in 

2030 (Cuatecontzi, 2008). Other significant area source contributors of CO emissions in 1999 

(e.g., wildfires, agricultural burning, and residential wood combustion) are projected to decrease 

by 2030. 

Residential wood combustion accounts for 51 percent of PM10 emissions and 68 percent 

of PM2.5 emissions in the 1999 MNEI. However, energy demand data indicate in a drop in 

residual wood combustion of almost 30 percent by 2030 (Cuatecontzi, 2008). This decrease in 

residential wood combustion demand accounts for the corresponding drop in PM10 and PM2.5 

emissions in 2030 relative to 1999 levels. As a result of this decrease, the agricultural tilling 

category increases in relative importance. 

The 2030 NH3 emissions are projected to decrease by approximately 35 percent 

compared to the 1999 inventory. Most of this decrease can be attributed to reductions in 

livestock ammonia as a result of projecting historical average livestock statistics.

4.2.3 On-Road Motor Vehicle Projections 

The 1999 on-road motor vehicle emissions were projected to 2008, 2012, and 2030 using 

two different growth factors. The first growth factor accounted for the increased demand of 

motor vehicle fuels projected between 1999 and 2030. As with many of the area source 

categories, future year gasoline use projections were generated using the Long-range Energy 

Alternatives Planning System (LEAP) (Cuatecontzi, 2008). 

The second growth factor addressed the changes in vehicle technologies and emissions 

due to the turnover of the Mexican fleet. Over time, newer vehicles with improved technologies 

(e.g., improved catalysts, etc.) and lower emissions will enter the vehicle fleet and gradually 

replace older vehicles with limited or no technology. The effects of vehicle turnover were 

estimated using the MOBILE6-Mexico on-road motor vehicle emission factor model (ERG, 

2003b). The MOBILE6-Mexico model was run for all years (i.e., 1999, 2008, 2012, and 2030) 

and fleet average emission rates were generated. The ratio of fleet average emission rates for 

each future year relative to the 1999 base year was calculated; this ratio was the “turnover” 

factor. The overall growth factor for each of the future years was estimated by multiplying the 

fuel growth factor by the fleet turnover factor. A more detailed explanation of the MOBILE6-

Mexico modeling process is provided below. 

MOBILE6-Mexico Modeling – Fuel Regulations 

The MOBILE6-Mexico model was modified to reflect new gasoline and diesel fuel 

standards regulations that would come into effect in Mexico in the future. Mexican fuel 

standards are split into three regions (i.e., Metropolitan Zone [ZM], Frontier Zone [ZF], and the 

remainder of the country [RP]) with each region having an applicable gasoline and diesel sulfur 

standard. 

Table 14 lists the Mexican fuel sulfur standards by fuel type and region for the 1999 base 

year and the three future years. These fuel sulfur standards were obtained from the fuel standard 

implementation schedule provided by INE staff (PEMEX, 2008). It should be noted that 

individual values in Table 14 represent maximum standards, while split values (e.g., 30/80) 

represent average/maximum standards, respectively. Also, for Magna gasoline, the Frontier 

Zone (ZF) is considered to be part of the remainder of the country (RP). Although both Magna 
Mexico Projections 

Final, January 9, 2009

15

and Premium gasoline are used in Mexico, only Magna gasoline (i.e., the predominant motor 

vehicle fuel) was used in the modeling runs in order to simplify the analysis. 

MOBILE6-Mexico Modeling – Other Model Parameters 

The average temperature range for Mexico was assumed to be a minimum of 55.6 oF and 

a maximum of 82.9 o

F for all the model runs. The fuel Reid Vapor Pressure (RVP) was assumed 

to be 7.5 psi and the average vehicle speed was assumed to be 18.5 kilometers per hour for all 

the model runs. 

MOBILE6-Mexico Modeling – Emission Standards 

Mexico has motor vehicle emission limits standards that are equivalent to a combination 

of U.S. Tier 1 and Tier 2 standards and European EURO 3 and EURO 4 standards (López 

Villegas, 2008b). The equivalency of Mexican motor vehicle emission standards to EURO 

standards and U.S. standards is shown in Table 15. Because the MOBILE6-model is based an 

80,000 km (i.e., 50,000 miles) certification rather than a 100,000 km certification, the U.S. Tier 1 

and Tier 2 standards were used for the modeling runs and the EURO 3 and EURO 4 standards 

were not investigated further. 

The 1999 base year model runs in Mexico were assumed to be equivalent to U.S EPA’s 

Tier 0 standards. For the future years of 2008, 2012, and 2030, the Mexican A, B, and C 

standards were incorporated into the MOBILE6-Mexico model runs. Mexican Standard A is 

similar to the U.S EPA’s Tier 1 standard for VOC, CO, and NOx. Standards B and C are a 

combination of U.S. EPA’s Tier 1 and Tier 2 standards for VOC, CO, and NOx. For particulate 

emissions, Mexican Standards A, B, and C were all the same as U.S EPA’s Tier 1 standard. In 

addition, there are no emissions standards in Mexico for heavy-duty gasoline trucks and vehicles 

(HDGV and HDGT). Mexican Standards A, B, and C are presented in Table 16 (Diario Oficial, 

2005). The vehicle types used in the Mexican standards are defined below: 

• PV – Passenger vehicle (light-duty) with a maximum gross vehicle weight rating 

(GVWR) of 8,500 lbs or less 

• LDT1 – Light-duty truck with a maximum loaded vehicle weight (LVW) of 3,750 lbs 

and GVWR not to exceed 6,000 lbs 
Mexico Projections 

Final, January 9, 2009

16

• LDT2 – Light-duty truck with a minimum LVW of 3,750 lbs and GVWR not to 

exceed 6,000 lbs 

• LDT3 – Light-duty truck with a maximum adjusted loaded vehicle weight (ALVW) 

of 5,750 lbs and GVWR greater than 6,000 lbs 

• LDT4 – Light-duty truck with a minimum ALVW of 5,750 lbs and GVWR not to 

exceed 6,000 lbs. 

The phase-in schedule of Mexican Standards A, B, and C as a percentage of vehicles 

within each model year are presented in Table 17. As shown in Table 17, the 2008 phase-in 

schedule indicates a 50 percent allocation for Standard A and 50 percent allocation for Standard 

B. The schedule for 2012 consists of a 75 percent allocation for Standard B and a 25 percent 

allocation for Standard C. By 2015, Standard C will be phased in entirely. Lacking information 

regarding additional future standards beyond Standard C, it was assumed that the Standard C 

would still be in effect in 2030. 

MOBILE6-Mexico Modeling – Implementation Schedule Input File 

The external input file that contains information relevant to the emission standard 

implementation schedule is called the Mex_P94_Imp.dat. This file contains the implementation 

schedule from model year 1994 thru model year 2025 (inclusive). The file contains the fraction 

of implementation for different standards for each of the above mentioned years by vehicle type 

(e.g., Tier 0, Tier 1 (interim) Tier 1, Tier 2, Tier LEV (interim), Tier LEV, etc.). For purposes of 

this projection analysis, only Tier 1 and Tier 2 standards are analyzed for future year scenarios. 

The format of the Mex_P94_Imp.dat file (i.e., unmodified default file from MOBILE6-Mexico) 

is shown in Figure 1 (included after all of the tables). Figure 1 shows the implementation 

schedule for LDGV. Columns represent standards (e.g., Tier 0, Tier 1 (interim), Tier 1, Tier 2, 

etc.), while rows represent model years (i.e., first row is 1994 and last row is 2025). In Figure 1, 

the first row of values indicate that for 1994 model year LDGVs, there was 100 percent 

implementation of Tier 0 standards, while the fourth row of values indicate that for 1997 model 

year LDGVs, there was 60 percent implementation of Tier 0 standards and 40 percent 

implementation of Tier 1 (interim) standards. 

The implementation schedule input file (i.e., Mex_P94_Imp.dat) was modified to 

represent the Mexican implementation schedule for Standards A, B, and C as follows:

• 1999 run for HC, CO, and NOx: 100 percent Tier 0 

• 2008 run for HC, CO, and NOx: 50 percent Tier 1 and 50 percent Tier 2 

• 2012 run for HC, CO, and NOx: 70 percent Tier 1 and 30 percent Tier 2 

• 2030 run for HC, CO, and NOx: 100 percent Tier 2 

• 1999 run for PM, SO2, and NH3: 100 percent Tier 0 

• 2008 run for PM, SO2, and NH3: 100 percent Tier 1 

• 2012 run for PM, SO2, and NH3: 100 percent Tier 2 

• 2030 run for PM, SO2, and NH3: 100 percent Tier 2 

MOBILE6-Mexico Modeling – Certification Standards Input File 

The external input file that contains information regarding vehicle manufacturer 

certification standards is called Mex_T2CERT.dat. The Mex_T2CERT.dat file contains the 

50,000 mile certification standards by certification bin by pollutant (HC, CO, and NOx). The 

format of the Mex_T2CERT.dat file (i.e., unmodified default file from MOBILE6-Mexico) is 

shown in Figure 2. Figure 2 presents the Mexican certification standards for Mexico for HC and 

CO by vehicle type. Columns represent vehicle type (i.e., LDV, LDT1, LDT2, LDT3, and 

LDT4), while rows represent certification bins 1 through 12 for each pollutant. In the first 

matrix (i.e., group of 12 rows), the first row indicates an HC standard of 0.25 g/mile for LDV 

and LDT1, an HC standard of 0.32 g/mile for LDT2 and LDT3, and an HC standard of 0.38 

g/mile for LDT4. The second matrix contains CO standards and the third matrix (not shown in 

Figure 2) contains NOx standards. In order to represent Mexican Standards A, B, and C, only 

bins 1, 2, and 3 were used with the remaining bins left blank or zero. The Mex_T2CERT.dat file 

was only applicable for HC, CO, and NOx. The same modified Mex_T2CERT file was used for 

all MOBILE6-Mexico runs (i.e., 1999, 2008, 2012, and 2030). 

MOBILE6-Mexico Modeling – Exhaust Emission Standards Input File 

The external input file that contains information regarding the phase-in schedule for the 

Tier 2 exhaust emission standards is called Mex_T2EXH.dat. The format of the 

Mex_T2EXH.dat is shown in Figure 3. The 12 columns represent model years 2004 through 

2015, while the 180 rows represent the 12 certification bins for each vehicle type (i.e., LDV, 
Mexico Projections 

Final, January 9, 2009

18

LDT1, LDT2, LDT3, and LDT4) by pollutant (i.e., HC, CO, and NOx). Rows 1 through 12 

contain bins 1-12 for LDV HC, rows 13 through 24 contain bins 1-12 for LDV CO, and rows 25 

through 36 contain bins 1-12 for LDV NOx. A similar pattern holds for LDT1 HC, CO, and NOx

in rows 37 through 72; LDT2 HC, CO, and NOx in rows 73 through 108, etc. 

The modified Mex_T2EXH.dat file is presented in Figure 3. Bins 1, 2, and 3 are used to 

represent Mexican Standards A, B, and C, while bins 4 through 12 are all blank or zeroes. In 

Row 1, bin1 (i.e., Mexican Standard A for HC) indicates 100 percent phase-in from 2004 to 

2006; dropping to 75 percent in 2007, 50 percent in 2008, and 30 percent in 2009; and then total 

phase-out (i.e., 0 percent) beginning in 2010. In Row 2, bin 2 (i.e., Mexican Standard B for HC) 

begins phase-in at 25 percent in 2007, reaches 100 percent phase-in in 2010 and 2011, and then 

total phase-out in 2015. In Row 3, bin 3 (i.e., Mexican Standard C for HC) phases in at 25 

percent in 2012, 50 percent in 2013, 70 percent in 2014, and then reaches 100 percent phase-in in 

2015. Similar phase-in schedules are also included in Rows 13 through 15 (for CO) and Rows 

25 through 27 (for NOx). Since this file only contains phase-in schedule until 2015, it was 

assumed that 2030 standards will be the same as those in 2015. This external file is applicable 

only for HC, CO, and NOx emissions and is same for all runs (i.e., 1999, 2008, 1012, and 2030). 

MOBILE6-Mexico Emission Factors 

After making modifications to the Mex_P94_Imp.dat, Mex_T2CERT.dat, and 

Mex_T2EXH.dat external input files, the MOBILE6-Mexico model was then run to generate 

fleet average emission factors for the base year 1999, as well as for the future projection years of 

2008, 2012, and 2030. These model runs accounted for both Mexican fuel standards and 

emission standards. After the fleet average emission factors were generated, turnover factors 

were calculated by dividing the future year emission factors by the base year 1999 emission 

factors. These future year turnover factors were then multiplied by the future year gasoline 

growth factors (Cuatecontzi, 2008) to develop a set of composite projection factors that were 

used to project 1999 base year on-road emissions to 2008, 2012, and 2030. The composite 

projection factors by pollutant and region are presented in Table 18. 

As can be seen in Table 18, there are projected to be significant reductions in NOx, SO2, 

VOC, and CO emission factors by 2030, in spite of increased motor vehicle fuel use. The 
Mexico Projections 

Final, January 9, 2009

19

reductions in NOx, VOC, and CO are due to fleet turnover, which gradually incorporates cleaner 

vehicles into the overall fleet over time. The reductions in SO2 are attributable to the lower 

sulfur contents in the future Mexican fuel standards. Increased PM10 and PM2.5 emissions are the 

result of increased fuel use without any future PM standards, while increased NH3 emissions are 

likely due to fleet turnover (i.e., new vehicle technologies, such as advanced catalytic converters 

tend to reduce NOx, but increase NH3). 

The projected baseline on-road motor vehicle emission totals are summarized in Table 

19, along with the initial 1999 area source emission totals. Baseline on-road motor vehicle 

emissions disaggregated by vehicle classification are presented in Table 20. The disaggregated 

emissions are also presented on a percentage basis in Table 21. 

4.2.4 Nonroad Mobile Source Projections 

The 1999 nonroad mobile source emissions were projected to 2008, 2012, and 2030 using 

energy demand projections. The 1999 nonroad mobile source categories were limited to dieselpowered agricultural equipment and diesel-powered construction equipment, only, due to the 

lack of Mexico-specific activity data for other types of nonroad equipment (e.g., recreational 

vehicles, lawn and garden equipment, etc.). Future year fuel use projections were generated 

using LEAP (Cuatecontzi, 2008); these projections included disaggregated demand data for the 

transportation, industrial, commercial, and agricultural sectors. 

Diesel energy demand in the agricultural sector was used as a surrogate to project 

nonroad emissions from the agricultural equipment source category. The data indicated an 

increase of approximately 75 percent in diesel usage for agricultural equipment in 2030 

compared to 1999 usage. Diesel energy demand in the commercial sector was used as a 

surrogate to project 1999 nonroad emissions for construction equipment. The data indicated an 

increase of approximately 57 percent in diesel usage for construction equipment in 2030 

compared to 1999 usage. 

 A summary of baseline nonroad mobile source emissions is provided in Table 22. 
Mexico Projections 

Final, January 9, 2009

4.3 Projections Summary 

The entire projected baseline Mexico NEI emissions are summarized in Table 23 by 

emission type, along with the initial 1999 inventory. The projected baseline emissions are also 

presented on a percentage basis in Table 24. 

In general, emissions from point sources, area sources, and nonroad mobile sources are 

projected to increase in future years relative to the 1999 base year. The projection factors for 

these source types are primarily driven by population growth, GDP growth, and fuel growth. 

There are also a few source categories with decreasing emissions (i.e., area source SO2, PM10, 

and PM2.5); these are due to projected decreases in certain fuel types and uses (i.e., commercial 

combustion of residual fuel oil and residential wood combustion). 

As described in Section 4.2.3, on-road motor vehicle NOx, SO2, VOC, and CO emissions 

are projected to decrease in future years relative to the 1999 base year, while PM10, PM2.5, and 

NH3 emissions increase. Although the demand for motor vehicle fuel will increase in the future, 

the decreases in NOx, SO2, VOC, and CO emissions are due to effects of new control 

technologies that are gradually incorporated into the overall vehicle fleet due to turnover, as well 

as low sulfur fuels. Because new motor vehicle standards are not being implemented for PM10, 

PM2.5, and NH3, emissions are projected to increase in the future for these pollutants. 

5.0 CONTROL SCENARIOS 

Following the development of base year emission projections for 2008, 2012, and 2030, 

additional analysis was conducted involving three control scenarios and their effect on future 

emissions. All three control scenarios focus only on on-road motor vehicles and do not affect 

point, area, or nonroad mobile sources. Details of the control scenarios and the associated 

control levels were developed by INE staff (Iniestra Gómez, 2008), and are described in the 

following subsections. 

5.1 Control Scenario 1 – Increased Fuel Economy 

The first control scenario considers an increase in fuel economy for new light-duty 

gasoline vehicles and trucks; the fuel economy for all other vehicle types is assumed to be 

unchanged. The baseline fuel economy for new vehicles is assumed to be 10.82 kilometers per 

liter (km/l), and will begin increasing by 1 km/l annual in 2011 until reaching a value of 15.82 
Mexico Projections 

Final, January 9, 2009

21

km/l in 2015 and all subsequent years. The pollutant specific reductions are presented in Table 

25. No emission reductions will occur in the future year 2008; reductions will only occur in 

2012 and 2030. In addition, no emission reductions were quantified for SO2 or NH3. 

5.2 Control Scenario 2 – Use of Ethanol in Oxygenated Fuel 

Oxygenated fuels have been used in the major metropolitan zones of Mexico since 1990 

in order to reduce ozone levels. The oxygenated gasoline supplied by PEMEX contains methyl 

tert-butyl ether (MTBE) and/or tertiary amyl methyl ether (TAME). PEMEX is currently 

contemplating switching from MTBE/TAME to ethanol. 

The second control scenario involves the switch from MTBE/TAME oxygenates to 

ethanol while maintaining an oxygenate level of 2 percent by weight as required by NOM-086. 

The switch is assumed to begin in Guadalajara in 2010, follow in Monterrey in 2011, and finish 

in Mexico City in 2012. The municipalities affected by this switch are listed in Table 26. All 

other fuel characteristics (e.g., Reid vapor pressure [RVP], etc.) are assumed to remain 

unchanged. The switch to oxygenated fuel with ethanol was assumed to only affect gasolinefueled vehicles (i.e., light-duty gasoline vehicles, light-duty gasoline trucks, heavy-duty gasoline 

vehicles, and motorcycles). 

The reductions for Guadalajara, Monterrey, and Mexico City are presented in Table 27. 

No emission reductions will occur in the future year 2008; reductions will only occur in 2012 

and 2030. The emission reductions were applied for all inventoried pollutants. 

5.3 Control Scenario 3 – Combined Increased Fuel Economy and Use of 

Ethanol in Oxygenated Fuel 

The third control scenario is the combined implementation of Control Scenario 1 and 

Control Scenario 2 and does not include any new control strategies. The effects of Control 

Scenarios 1 and 2 are applied by calculating the reduced emissions due to Control Scenario 1 and 

then applying the controls from Control Scenario 2. The effect of Control Scenario 3 is 

dependent on the vehicle classification, pollutant, or geographically location to which it is 

applied. For example, Control Scenario 3 for light-duty gasoline vehicle NOx emissions in 

Guadalajara would include the control effects from both Control Scenario 1 and Control 
Mexico Projections 

Final, January 9, 2009

22

Scenario 2, while Control Scenario 3 for heavy-duty diesel vehicle emissions in the state of 

Sonora would have no control effects from Control Scenario 1 or Control Scenario 2. 

5.4 Projections Summary with Controls 

The projected on-road motor vehicle emission totals, including the effects of Control 

Scenarios 1, 2, and 3 are summarized in Table 28. Control Scenarios 1, 2, and 3 are identified 

with the abbreviations CS1, CS2, and CS3, respectively. For reference purposes, the baseline 

projected emission totals for 1999, 2008, 2012, and 2020 from Table 19 have also been included. 

The projected on-road motor vehicle emissions including controls disaggregated by 

vehicle classification are presented in Table 29. For reference purposes, the baseline projected 

emission totals for 1999, 2008, 2012, and 2020 from Table 20 have also been included. 

Because Control Scenarios 1, 2, and 3 are based upon on-road motor vehicle control 

strategies, only on-road motor vehicle emissions are presented in Table 28 and Table 29. Point 

source, area source, and nonroad mobile source emissions are not impacted by Control Scenarios 

1, 2, and 3. 

The emission reductions due to Control Scenario 1 vary from 0.1 percent to 0.6 percent 

for 2012 and from 1.1 percent to 5.0 percent for 2030; Control Scenario 1 does not affect SO2

and NH3, so these are not included in these reduction values. The percentage reductions due to 

Control Scenario 1 relative to baseline emissions increase over time because new vehicles with 

improved fuel economy gradually penetrate the overall vehicle fleet over time, thereby raising 

the fleet average fuel economy and decreasing emissions from the fleet. 

The percentage reductions due to Control Scenario 2 vary from 0.6 percent to 1.3 percent 

for 2012 and from 0.5 percent to 1.3 percent for 2030. The emission reductions due to Control 

Scenario 2 relative to baseline emissions are fairly constant from 2012 to 2030 because the 

switch from MTBE/TAME-based oxygenated fuels to ethanol-based oxygenated fuels is a onetime event that does not have increasing penetration over time. 

As expected, emission reductions due to Control Scenario 3 are greater than those of 

Control Scenarios 1 or 2 applied individually, and range from 0.7 percent to 1.5 percent for 2012, 

and from 1.0 percent to 5.7 percent for 2030.

6.0 HARMONIZATION WITH GREENHOUSE GAS EMISSIONS INVENTORIES 

An objective to be accomplished as part of the development of emissions projections is to 

“harmonize” the future year criteria pollutant emission projections with current and future year 

greenhouse gas emissions inventories in Mexico. The term “harmonize” refers to standardizing 

or increasing comparability and/or convergence between inventories. 

Because of methodological differences between criteria pollutant and greenhouse gas 

inventories, there are inherent differing aspects between the two types of inventories. For 

example, VOC emissions from consumer solvents are typically estimated with an annual per 

capita emission factor combined with population counts; however, consumer solvents do not 

generate greenhouse gas emissions. In contrast, fuel combustion is a source of both criteria 

pollutants (i.e., NOx, SO2, CO, and VOC) and greenhouse gases (i.e., carbon dioxide, methane, 

and nitrous oxide). . 

In order to ensure harmony between criteria pollutant and greenhouse gas emission 

inventories, INE provided important data and assumptions used in the development of Mexico’s 

greenhouse gas emissions inventories. For example, future year fuel use projections from LEAP 

were developed to estimate greenhouse gas emissions in Mexico (Cuatecontzi, 2008). These 

future fuel use projections were then used in this project to generate criteria pollutant growth 

factors for a wide number of sources categories, including: point source electric generating units 

(EGUs), area source fuel combustion (i.e., industrial, commercial/institutional, residential, and 

agricultural), area source fuel distribution (i.e., gasoline and LPG), on-road motor vehicles (in 

conjunction with the MOBILE6-Mexico analysis), and nonroad mobile sources. In addition, 

underlying economic assumptions, such as annual Gross Domestic Product (GDP) growth rates 

(Galindo Paliza, 2008), were used to develop projection factors for some point sources (i.e., 

manufacturing industries and miscellaneous industries) and some area source categories (i.e., 

locomotives, industrial surface coating, and degreasing) in this project. 

A certain level of harmony was obtained by using information from Mexico greenhouse 

gas inventories to develop projection factors for the future year criteria pollutant projections. In 

some cases, momentary pauses in the project schedule occurred to ensure that the most up-to-
Mexico Projections 

Final, January 9, 2009

date greenhouse gas inventory information was obtained, rather than using outdated information 

or information unrelated to greenhouse gas inventories.
