Earlier this week, the U.S. Environmental Protection Agency (EPA) released its 20th Annual Inventory of U.S. Greenhouse Gas Emissions for the 2013 calendar year. The inventory reveals a 2% increase in greenhouse gas emissions in 2013 from 2012 levels, attributed to increased energy consumption and coal use. Greenhouse gas emissions totaled 6,673 metric tons of carbon dioxide equivalent. The largest sources, by percentage are: power plants at 31%, transportation at 27% and industry/manufacturing at 21%.
The EPA is presenting its data in the Greenhouse Gas Inventory Data Explorer Tool. The tool allows users to sort data by sector, date and specific greenhouse gas. The EPA is hosting a webinar April 22 at 1:00 p.m. EST to provide a tutorial on using the site.
