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

Consumption-based power mixes and NG transmission distances by Chinese province in 2010. 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.

New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications.

Black carbon linked to increased cardiovascular risk; exacerbated by co-exposure to motor vehicle emissions

Green Car Congress

Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health.

Study finds 1.4 Gt discrepancy between national and provincial data sets for greenhouse gas emissions in China

Green Car Congress

A study lead by researchers from the Institute of Applied Ecology, Chinese Academy of Sciences has found a 1.4-gigatonne The gap, noted the researchers in their open-access paper in Nature Climate Change , is equivalent to Japan’s annual CO 2 emissions, the world’s fourth largest emitter, with 5% of the global total.

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 ”. The power of EVs is electricity from the grid.

US and China jointly announce GHG reduction targets; US to cut net GHG 26-28% by 2025, China to peak CO2 by ~2030

Green Car Congress

The Administration said the United States will submit its 2025 target to the Framework Convention on Climate Change as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015. launching a new track on the interaction of energy and water (the energy/water ‘nexus’).

Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5
