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. This highlights the potential of co-beneficial solutions to climate change that not only curb greenhouse gas emissions but also reduce the health burden of harmful air pollution.

California introduces first-in-nation rules to reduce climate “super pollutants” from commercial refrigeration, air conditioning equipment

Green Car Congress

HFCs are considered to be super pollutants because they trap heat in the atmosphere thousands of times more effectively than carbon dioxide, the most prevalent greenhouse gas. The California Air Resources Board recently approved first-in-the-nation rules to curb the impact of hydrofluorocarbon (HFC) refrigerants.

Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. Estimates indicate that aerosols have offset about a third of greenhouse gas-driven warming since the 1950s. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted. Climate Change Emissions
