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.

Report finds says “negative emissions technologies” need to play a large role in mitigating climate change

Green Car Congress

To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine. Most climate mitigation efforts are intended to decrease the rate at which people add carbon from fossil fuel reservoirs to the atmosphere.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. From a global climate change perspective, it does not matter where or from what source the reduction occurs: the effect on the atmospheric concentration of GHGs would be the same.
