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.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C Their paper is published in the journal Science.

ADB draft report says 3B Asians could become affluent by 2050; significant challenges

Green Car Congress

Asia’s long-term competitiveness will depend heavily on how it controls the intensity of its resource use, including water and food, and manages its carbon footprint. For example, half of all Asians live without basic sanitation while 900 million people in the region have no access to electricity. —Asia 2050.
