Comprehensive assessment concludes black carbon second-most important human emission in warming climate

Green Car Congress

A comprehensive assessment of black-carbon climate forcing accepted for publication in the Journal of Geophysical Research: Atmospheres estimates that black carbon, with a total climate forcing of +1.1?W?m m -2 , is the second-most important human emission in terms of its climate-forcing in the present-day atmosphere.

MIT report finds China’s actions on climate change crucial; argues for global economy-wide greenhouse gas tax

Green Car Congress

The report—titled “The Role of China in Mitigating Climate Change” and published in the journal Energy Economics , compares the impact of a stringent emissions reduction policy with and without China’s participation. From 2000 to 2010, China’s energy use grew 130%, up from a growth of 50% the previous decade.

UK new car CO2 emissions fell 3.5% in 2010 and more than 20% since 2000

Green Car Congress

Average CO 2 emissions from new cars have fallen by more than 20% since 2000. Cars in the sub-130 g/km CO 2 category represented almost 40% of the market in 2010 compared with less than 1% in 2000. Executive (-28.1%) and Mini (-25.8%) segments recorded the biggest improvements against the levels of 2000. .
