Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University. —Newell and Raimi.

EEA report: EVs are better for climate and air quality

Green Car Congress

The EEA report ‘ Electric vehicles from life cycle and circular economy perspectives ’ reviews current evidence on electric cars’ impacts on climate change, air quality, noise and ecosystems, compared with conventional cars. The EEA has also published a new briefing on the environmental and climate impacts of transport.

MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

The report—titled “The Role of China in Mitigating Climate Change” and published in the journal Energy Economics , compares the impact of a stringent emissions reduction policy with and without China’s participation. The researchers argue for a global economy-wide greenhouse gas tax that spreads the burden of responsibility.

OECD: governments should make better use of energy taxation to address climate change; “meaningful” increases limited to road sector

Green Car Congress

Greater reliance on energy taxation is needed to strengthen efforts to tackle the principal source of both greenhouse gas emissions and air pollution, according to a new OECD report. Tax rates were below the low-end estimate of climate costs (EUR 30/tCO 2 ) for 97% of emissions. In road transport, 97% of emissions are taxed.

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) Credit: ACS, Huo et al. Click to enlarge.

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.

EPA: US greenhouse gases dropped 3.4% in 2012 from 2011; down 10% from 2005 levels

Green Car Congress

US greenhouse gas emissions by gas. The US Environmental Protection Agency (EPA) released its 19 th annual report of overall US greenhouse gas (GHG) emissions, showing a 3.4% decrease in 2012 from 2011. Total emissions of the six main greenhouse gases in 2012 were equivalent to 6,526 million metric tons of carbon dioxide.
