Read MoreGreenhouse gases are measured in ‘carbon dioxide-equivalents’ (CO 2 e). Today, we collectively emit around 50 billion tonnes of CO 2 e each year. This is more than 40% higher than emissions in 1990, which were around 35 billion tonnes. What are carbon dioxide equivalents (CO2e)?

Read More2017-12-4 Coal fires produce all kind of greenhouse gases: CO, CO 2, CH 4, NO X SO x etc. Due to the incomplete combustion under the surface, coal fires in the underground produce more of these gases, then a complete combustion of coal at the surface. A complete combustion of 1000 kg of coal with 750 kg of C leads to 2.7 tons of CO 2.
Read More2014-5-2 Electricity generators consumed 36 % of the U.S. energy from fossil fuels and emitted 42 % of the CO 2 from fossil fuel combustion in 2007. In 2010 electricity generation from coal was the largest emitter of greenhouse gases (GHGs) with coal combustion for electricity accounting for 1827.3 terra gram (Tg) CO 2 equivalent (EPA 2012 ).
