New inventory of black carbon emissions from China finds 2007 levels higher than previously reported

Green Car Congress

for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. The paper by researchers from Peking University and Environment Canada appears in the ACS journal Environmental Science & Technology. Click to enlarge.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

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).

In particular in the US, where gasoline prices almost doubled in the summer of 2008 compared to 2007 levels, oil consumption dropped 7% decrease. In China, oil consumption increased by 3% in 2008, according to BP data, which was down from 5% in 2007 and 8%, on average, since 2001. Emissions increased by 1.7% in 2008, against 3.3%

billion tons of carbon dioxide (CO 2 )—a byproduct of fossil fuel burning—and 12.2 molecules of carbon dioxide entered the atmosphere last year and stayed there—slightly less than the 2.2 parts per million (ppm) increase in 2007. The carbon dioxide record isn’t immune to temporary dips lasting several years or more.
