Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ, 26%), while land use change is a minor contributor (3.9 —Scully et al.

Separate MIT, IEA reports both outline major expansion in role of natural gas; caution on climate benefits

Green Car Congress

World primary energy demand by fuel in the IEA high gas scenario. Separately, the International Energy Agency (IEA) released its own report exploring the potential for a “golden age” of gas. Both reports also emphasized that although natural gas is the lowest carbon fossil fuel, it is still a fossil fuel. Source: IEA.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. The EEA has also published a new briefing on the environmental and climate impacts of transport.

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

Setting a cap on coal use while maintaining economic growth at a high level means that China must resort to other energy sources, such as natural gas (NG) and renewable fuels, to fill the energy supply gap. It also assesses the strengths and weaknesses of EVs and CNGVs from a perspective of climate change and environmental impact.
