A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

New phase of globalization could undermine efforts to reduce CO2 emissions

Green Car Congress

A new study finds that the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalization” between developing countries that could undermine international efforts to reduce emissions. The paper is published in Nature Communications.

AQLI: new data reveals little progress globally in reducing air pollution over the last two decades

Green Car Congress

Produced by the Energy Policy Institute at the University of Chicago (EPIC), the AQLI is based on frontier research by EPIC’s director Michael Greenstone that quantified the causal relationship between human exposure to air pollution and reduced life expectancy.

HEI: 95%+ of world’s population live in areas of unhealthy air

Green Car Congress

China has made initial progress, beginning to achieve air pollution declines; in contrast, Pakistan, Bangladesh, and India have experienced the steepest increases in air pollution levels since 2010. Its results are published each year in the international medical journal, The Lancet.

The scientific case for such a strategy was laid out in an Op Ed in The New York Times by Professor Veerabhadran Ramanathan, from the Scripps Institution of Oceanography at the University of California, San Diego, and his colleague, Professor David Victor. million lives lost each year due to black carbon soot.
