U.S. greenhouse gas emissions grew 1.4 percent in 2007, according to "Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2007."
The Environmental Protection Agency released a draft of the report in early March, and had been taking public comments until recently.
From 1990 to 2007, overall U.S. emissions have grown 17.1 percent, the report states.
Because of high prices at the pump, and warmer winters, emissions from fuel combustion decreased slightly from 2005 to 2006, but emissions from 2006 to 2007 increased at a rate slightly higher than the average growth rate since 1990, according to the report.
The boost from 2006 to 2007 can be attributed to a colder winter and warmer summer, meaning a jump in consumption of heating fuels, as well as an increase in electricity demand.
