Black carbon emissions and BC emissions intensity per year. A study led by a team from Peking University has estimated that global black carbon (BC) emissions increased from 5.3 teragrams per year in 2007 (+72%). Among their findings: The residential sector is the most important anthropogenic BC emission source.

greenhouse gas emissions were 6,472.3 The decrease in total greenhouse gas emissions between 2016 and 2017 was driven in part by a decrease in CO 2 emissions from fossil fuel combustion. Relative to the 1990 baseline, gross emissions in 2017 were higher by 1.6%, down from a high of 15.7% above 1990 levels in 2007.

US energy-related CO 2 emissions decreased by 89 million metric tons (MMmt), from 5,259 MMmt in 2015 to 5,170 MMmt in 2016. over that period, other factors contributing to energy-related CO 2 emissions more than offset the growth in GDP, leading to a 1.7% Natural gas CO 2 emissions have increased every year since 2009.
