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

Green Car Congress

The report’s best estimate of direct climate influence by black carbon is about a factor of two higher than most previous work. This includes the estimates in the 2007 Intergovernmental Panel on Climate Change (IPCC) Assessment, which were based on the best available evidence and analysis at that time. Bond et al.

Survey finds public support for geoengineering research; strongest opposition from conservatives

Green Car Congress

Eight percent of the sample were able to provide a correct definition of geoengineering, an increase on previous estimates; however, 45% of the sample correctly defined the alternative term “climate engineering”, adding weight to the argument that “geoengineering” may be misleading and difficult to understand.

EEA TERM Report Finds Efficiency Gains of Clean Vehicle Technology Being Offset By Ongoing Increases in Travel

Green Car Congress

Based on analysis of long-term trends, a new European Environment Agency (EEA) report calls for a clear vision defining Europe’s transport system by 2050 and consistent policies to achieve it. Unlike some sectors, transport’s impact on the environment continues to be closely linked to economic growth.

EEA: Higher EU greenhouse gas emissions in 2010 due to economic recovery and cold winter

Green Car Congress

Greenhouse gas emissions increased in the EU in 2010 as a result of both economic recovery in many countries after the 2009 recession and a colder winter, according to the latest greenhouse gas inventory published by the European Environment Agency (EEA). The gas represented 82% of total EU GHG emissions.

Berkeley study finds renewable portfolio standards insufficient to meet 2030 GHG emission targets; new policy required

Green Car Congress

With a stronger carbon policy consistent with a 450 ppm climate stabilization scenario, power sector emissions can be reduced to 54% of 1990 levels by 2030 using different portfolios of existing generation technologies, they found. —Daniel Kammen, Distinguished Professor of Energy in UC Berkeley’s Energy and Resources Group.
