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

The JGR-Atmospheres Editors decided to provide a platform for this article because we believe that there is great scientific value in reviewing, assessing, and synthesizing a large body of existing literature, and by going beyond the conclusions that any individual paper can reach. In a special comment on the significance of the Bond et al.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. 3) Measurement. CONCLUSION.

OICR-led study shows that environmental exposures such as air pollution are more determinant of respiratory health than inherited genetics

Green Car Congress

Researchers from the Ontario Institute for Cancer Research (OICR), with colleagues at other institutions in Canada and the UK, have found strong evidence that environmental exposures, including air pollution, affect gene expressions associated with respiratory diseases much more than genetic ancestry. A permutation test ( n ?=?10,000

U Toronto studies find traffic emissions spread farther than thought; 25% of cars causing 90% of pollution

Green Car Congress

A trio of recently published studies from a team of University of Toronto engineers has found that air pollution could be spreading up to three times farther than thought, contributing to varying levels of air quality across cities. We used to think that living near a major road meant that you lived near a lot of air pollution.

Arizona State Students Develop a Solar-Powered Air Filtration System

Cars That Think

A team of students from the Fulton Schools of Engineering at Arizona State University is helping to improve the air quality for nomadic communities in Mongolia. A drought in Mongolia has led to food shortages, prompting the nomads to migrate to the Ger district in the capital of Ulaanbaatar, one of the world’s most polluted cities.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems. Click to enlarge.
