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. Black carbon is released into the atmosphere via incomplete combustion of carbonaceous fuel and is of major concern because of the impact on climate systems.

EPA says methane emissions from natural gas production have dropped 36% from 2007-2011

Green Car Congress

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 In 2011, CH4 emissions from coal mining were 63.2
