Study: 25% EV adoption would save US $17B annually from avoided climate change & pollution damages

Green Car Congress

A new study led by researchers from Northwestern University projects that if electric vehicles replaced 25% of combustion engine cars currently on the road, the United States would save approximately $17 billion annually by avoiding damages from climate change and air pollution. Results show that in more aggressive scenarios—i.e.,

The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Depletion of fossil energy resources [kg oil-eq.]. Deterioration of the ozone layer [kg CFC-11-eq.]. Primary energy, non-renewable [Megajoule]. in review).

Study finds anthropogenic PM and dust undercutting global solar energy production

Green Car Congress

According to a new study led by a team at Duke University, airborne particulate matter and dust are cutting solar photovoltaic energy output by more than 25% in certain parts of the world, with roughly equal contributions from ambient PM and PM deposited on photovoltaic surfaces.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. Between 2000 and 2010, both drivers outpaced emission reductions from improvements in energy intensity.

Aviation climate change impacts pathway. In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Credit: ACS, Stratton et al.

Study: air pollution causes 800,000 extra deaths a year in Europe and 8.8 million worldwide

Green Car Congress

The researchers used exposure data from a model that simulates atmospheric chemical processes and the way they interact with land, sea and chemicals emitted from natural and man-made sources such as energy generation, industry, traffic and agriculture. They focused particularly on PM 2.5 —Prof Lelieveld.
