Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

The researchers found that while EVs do offer a very promising solution to energy issues due to their replacement of petroleum fuels, for now “ the high pollution levels of coal-fired power plants will trade off EVs’ potential energy benefits in China ”. in 2006) but if they are replaced by EVs, the contribution would rise to 2-4%.

IEA: Global CO2 emissions up by 1.0 Gt (3.2%) in 2011 to record high

Green Car Congress

Coal accounted for 45% of total energy-related CO 2 emissions in 2011, followed by oil (35%) and natural gas (20%). China made the largest contribution to the global increase, with its emissions rising by 720 million tonnes (Mt), or 9.3%, primarily due to higher coal consumption. This represents an increase of 1.0 Gt on 2010, or 3.2%.
