The EPA is seeking public comment on a draft report that analyzes sources of greenhouse gas emissions. The report, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2005, will be open for public comment for 30 days after the Federal Register notice is published.
Overall U.S. greenhouse gas emissions during 2005 increased by less than one percent from the previous year. Total emissions of the six main greenhouse gases in 2005 were equivalent to 7,262 million metric tons of carbon dioxide. The draft report indicates that overall emissions have grown by 16 percent from 1990 to 2005, while the U.S. economy has grown by 55 percent over the same period.
