Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z.

Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5

CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. UC stands for uncontrolled charging and CC stands for controlled charging.

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.

Anglo American, Aurizon to explore feasibility of hydrogen-powered trains for bulk freight

Green Car Congress

Aurizon , Australia’s largest rail freight operator, and leading global mining company Anglo American will work together on a feasibility study to assess the introduction of hydrogen-powered trains for bulk freight. Rail freight already produces up to 16 times less carbon pollution per tonne kilometer than road. Earlier post.)
