Greenhouse gas emissions from power plants fell for the second straight year: from 2,331 million metric tons CO2e in 2010 to 2,222 in 2011 and 2,090 in 2012. Emissions from refineries also fell last year – from 178 to 173 mmt CO2e – after holding steady from 2010 to 2011.
But for the minerals sector, emissions rose from 101 mmt CO2e in 2010, to 103 in 2011 and 107 in 2012.
The EPA said it could not provide trends data for all reporting sectors, because of changes in data collection.
Overall emissions from all reporting sectors fell 4.4 percent, from 3,275 mmt CO2e in 2011 to 3,129.9 in 2012.
