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)

FCA says Jeep Wrangler environmental impact reduced by 15% compared to predecessor

Green Car Congress

The comparison was made with the previous-generation Wrangler Unlimited, as powered by its only available engine—FCA’s award-winning 3.6-liter tons of coal burned in a power-generation plant. Improvements are measured by contrasting anticipated CO 2 -equivalent greenhouse-gas (GHG) emissions, with those of comparable vehicles.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

Rice University researchers have determined a more effective way to use natural gas to reduce climate-warming emissions would be in the replacement of existing coal-fired power plants and fuel-oil furnaces rather than burning it in cars and buses. However, residential uses and exports of natural gas were not considered in those comparisons.

EEA report: EVs are better for climate and air quality

Green Car Congress

Promoting renewable energy and circular economy—including the shared use of vehicles and product design that supports reuse and recycling—will help maximize the benefits of shifting to electric vehicles, according to the report. —“Electric vehicles from life cycle and circular economy perspectives”.

ORNL study finds best current use of natural gas for cars is efficient production of electricity for EVs

Green Car Congress

However, they also noted, high PTW efficiencies and the moderate fuel economies of current compressed natural gas vehicles (CNGVs) make them a viable option as well. The study investigated the the WTW energy and emissions from the use of natural gas in CNGVs with a range of CNGV fuel economy and natural gas compressor efficiency.

PBL/JRC: Global CO2 emissions increase to new all-time record in 2013, but growth is slowing down

Green Car Congress

This was mainly due to the continuing steady increase in energy use in emerging economies over the past ten years. The emissions increase in the United States in 2013 (+2.5%) was mainly due to a shift in power production from gas back to coal together with an increase in gas consumption due to a higher demand for space heating.
