Study finds single exposure to roadway PM induces transient pulmonary stress; possible need to regulate non-tailpipe-related pollution

Green Car Congress

The effect of near roadway air pollution on human health is especially significant in major cities, and respiratory and cardiovascular diseases are mostly implicated in response to continued/repeated exposure to air pollution. The paper appears in the ACS journal Environmental Science & Technology. —Pardo et al. 5b01449.

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. Another three U.S.
