Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. According to the 12 th Five-Year Plan of the China Coal Industry (2011?2015)

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%.

Researchers Suggest That Although CCS and Other Technologies Could Reduce Oil Sands GHG Emissions to Near Zero, That Strategy May Not Make Sense

Green Car Congress

While oil sands emissions have more than doubled from 1990 to 2006, the absolute increase in emissions from oil sands over the same period is less than the absolute increase in Canadian electric or transportation sector emissions, and far less than the increases in these sectors on a North American basis, they note.

New 3-step process for conversion of kraft lignin from black liquor into green diesel

Green Car Congress

In a paper describing the kraft recovery process, Honghi Tran from the University of Toronto and Esa K. This makes black liquor the fifth most important fuel in the world, next to coal, oil, natural gas, and gasoline. For every ton of pulp produced, the kraft pulping process produces about 10 tons of weak black liquor or about 1.5
