Obama climate plan calls for new fuel economy standards for heavy-duty vehicles post-2018; cleaner fuels and investment in advanced fossil energy

Green Car Congress

Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Preparing the US for the impacts of climate change. Earlier post.).

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

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)

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.

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.
