Beside GHG emissions, we account for:• Nitrogen oxides (NOx).
• Carbon monoxide (CO).
• Non-Methane volatile organic compound (NMVOC).
• Sulfur dioxide (SO2).
• Black carbon (BC).

Consumo• Constant increase of vehicles
and energy fuel use.
• Decrease in BC emissions
since2000,duetoregulations.

Main uncertainties

The uncertainties are related to the main sources and others.
• Residential activities (1.A.4.)• Emission coming from wood burning.
• Difficult to quantify the annual consumption.
• High uncertainty in emission factor.
• Industrial activities (1.A.2.)• Strong participation of diesel and biomass from industries.
• Uncertainties in off-road machinery (e.g., standard, activitylevels, sectors).
• Methodology• Use of international EF.
• Consider BC as PM2.5 fraction.

Improvement plan and challenge• Downscale the estimation to subnational levels (politicalregions).
• Coordinate with national entities to better understand thegaps of information.
• Link climate and air quality policies.
• Improve methodology levels, through national studies.
• Develop national EF.
• Include other climate forcers to the estimation.
