Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. Determining effective strategies for mitigating surface ozone (O 3 ) pollution requires knowledge of the relative ambient concentrations of its precursors, NO x , and VOCs.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Stacked bars show the change in generation cost combined with the median damages by pollutant assuming the 2010 social cost of carbon given by the Office of Management and Budget ($31 in $2010). However, this shift results in increased externality costs of health and environmental damages from increased air pollution.

Perspective: Regional Greenhouse Gas Cap-and-Trade Programs May be the Solution

Green Car Congress

Cap-and-trade was first tried on a significant scale twenty years ago under the first Bush administration as a way to address the problem of airborne sulfur dioxide pollution–widely known as acid rain–from coal-burning power plants in the eastern United States. In 2015–nearly 90% of emissions. INTRODUCTION. Gases: All 6 Kyoto gases.
