ENVIRONMENTAL PROTECTION 

AGENCY 

[FRL–9784–3] 

Inventory of U.S. Greenhouse Gas 

Emissions and Sinks: 1990–2011 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of document availability 

and request for comments. 

SUMMARY: The Draft Inventory of U.S. 

Greenhouse Gas Emissions and Sinks: 

1990–2011 is available for public 

review. Annual U.S. emissions for the 

period of time from 1990 through 2011 

are summarized and presented by 

source category and sector. The 

inventory contains estimates of carbon 

dioxide (CO2), methane (CH4), nitrous 

oxide (N2O), hydrofluorocarbons (HFC), 

perfluorocarbons (PFC), and sulfur 

hexafluoride (SF6) emissions. The 

inventory also includes estimates of 

carbon fluxes in U.S. agricultural and 

forest lands. The technical approach 

used in this report to estimate emissions 

and sinks for greenhouse gases is 

consistent with the methodologies 

recommended by the Intergovernmental 

Panel on Climate Change (IPCC), and 

reported in a format consistent with the 

United Nations Framework Convention 

on Climate Change (UNFCCC) reporting 

guidelines. The Inventory of U.S. 

Greenhouse Gas Emissions and Sinks: 

1990–2011 is the latest in a series of 

annual U.S. submissions to the 

Secretariat of the UNFCCC. 

DATES: To ensure your comments are 

considered for the final version of the 

document, please submit your 

comments within 30 days of the 

appearance of this notice. However, 

comments received after that date will 

still be welcomed and be considered for 

the next edition of this report. 

ADDRESSES: Comments should be 

submitted to Mr. Leif Hockstad at: 

Environmental Protection Agency, 

Climate Change Division (6207J), 1200 

Pennsylvania Ave., NW., Washington, 

DC 20460, Fax: (202) 343–2359. You are 

welcome and encouraged to send an 

email with your comments to 

hockstad.leif@epa.gov.

Protection Agency, Office of Air and

Programs, Climate Change Division,

SUPPLEMENTARY INFORMATION: For this 

year’s public review, EPA is calling 

attention to two specific areas where 

interested stakeholders could provide 

feedback to improve the quality of the 

emission estimates. First, EPA is seeking 

comments on approaches for using 

facility-level data reported under EPA’s 

Greenhouse Gas Reporting Program 

(GHGRP), particularly data from 

reporters that began reporting in 2011. 

For selected source categories, EPA 

could use data elements reported under 

the GHGRP, such as facility-level data 

that can be aggregated at the national 

level, to derive country-specific 

emission factors for use in estimating 

industrial process emissions. Categories 

with GHGRP-related updates under 

consideration include nitric acid, 

petrochemical production, phosphoric 

acid, titanium dioxide, lime production, 

and several fluorinated gas categories. 

Interested stakeholders should review 

detailed methodological approaches in 

Chapter 4 (Industrial Processes) of the 

report. Depending on stakeholder 

feedback, EPA may include revised 

estimates in the final published 

inventory report that use these emission 

factors derived from the specified 

GHGRP data elements. 

The second area is the natural gas 

sector, which in recent years has 

experienced significant growth and 

changes in industry practices. EPA 

recently solicited and received new 

information and data related to 

emissions estimates for the oil and gas 

industry through a variety of 

mechanisms, including the formal 

public notice and comment process of 

the oil and gas New Source Performance 

Standards (NSPS) to control VOCs, a 

stakeholder workshop on the natural gas 

sector emissions estimates, and data 

submitted under the GHGRP. In 

developing the draft inventory report for 

this public comment period, EPA 

carefully evaluated relevant 

information, and has made updates to 

two key sources: liquids unloading, and 

completions with hydraulic fracturing 

and refracturing. EPA also made 

additional changes to the report to allow 

for more transparency. EPA seeks 

feedback on these updates, and on 

incorporation of GHGRP data, and 

requests recommendations for 

improving the overall quality of the 

inventory report to be finalized in April 

2013, as well as subsequent Inventory 

reports. 

The draft report can be obtained by 

visiting the U.S. EPA’s Climate Change 

Site at: http://www.epa.gov/
