Why EVs Aren't a Climate Change Panacea

Cars That Think

For instance, Alexandre Milovanoff at the University of Toronto and his colleagues’ research (which is described in depth in a recent Spectrum article ) demonstrates the U.S. must have 90 percent of its vehicles, or some 350 million EVs, on the road by 2050 in order to hit its emission targets. These will also have to be decarbonized.

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

Fortunately, we still have a narrow window of opportunity to alter the Earth’s climate path, and I believe we can do it. Climate change is a global societal crisis that is causing devastating consequences. Deforestation is contributing to climate change. We need to address the crisis now in a sustainable way.

Reducing Black Carbon Emissions and Ground-Level Ozone Would Provide Immediate Benefit Against Climate Change

Green Car Congress

Reducing emissions of black carbon soot and ground-level ozone would quickly make a considerable dent in the climate change problem and would also contribute to public health and protect crop yields, according to an essay in the September/October issue of Foreign Affairs.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

An offset is a measurable reduction, avoidance, or sequestration of GHG emissions from a source not covered by an emission reduction program. In this way, offsets would complement the more traditional emissions trading that can occur between two covered sources. what would have happened anyway).
