MIT Report Finds Natural Gas Has Significant Potential to Displace Coal, Reducing Greenhouse Gas Emissions; Role in Transportation More Limited

Green Car Congress

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

Study of lead isotopes provides insight into aerosols transport from Asia to US

Green Car Congress

About a third of the airborne lead particles collected at two sites in the San Francisco Bay Area came from Asia, a finding that underscores the far-flung impacts of air pollution and heralds a new way to learn more about its journey across vast distances. The isotopic composition of lead varies over large regions of the Earth’s crust.

Evidence from glacier ice: Until it was banned, leaded gasoline dominated the anthropogenic lead emissions in South America

Green Car Congress

Leaded gasoline was a larger emission source of the toxic heavy metal lead than mining in South America, even though the extraction of metals from the region’s mines historically released huge quantities of lead into the environment, according to a study by researchers from the Paul Scherrer Institute PSI and the University of Bern.
