EPA is seeking public comment on the annual Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2007 draft report. The gases covered by this inventory include carbon dioxide, methane, nitrous oxide, hydro fluorocarbons, perfluorocarbons, and sulfur hexafluoride. The inventory also calculates carbon dioxide emissions that are removed from the atmosphere by "sinks," such as through the uptake of carbon by forests, vegetation, and soils.
The draft report shows that overall emissions during 2007 increased by 1.4% from the previous year. This trend was due primarily to an increase in carbon dioxide emissions associated with fuel and electricity consumption. Overall, total U.S. greenhouse gas emissions have grown by 17.1% since 1990 to 7,125 million metric tons of CO2 equivalent.
This report will be open for public comment for 30 days after the Federal Register notice is published.
