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 Climate Change Emissions Natural Gas'

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

Copenhagen Diagnosis Released, Detailing Accelerating Indicators of Climate Change In Last Three Years

Green Car Congress

A team of 26 climate scientists from Australia, Austria, Canada, France, Germany, Switzerland, the United Kingdom, and the United States have published the “Copenhagen Diagnosis”, an interim synthesis report on developments in climate change science from mid-2006 to the present day.

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.

Green Car Congress

Widespread climate-related impacts are occurring now in the US and are expected to increase. A product of the interagency US Global Change Research Program, the 190-page report was commissioned in 2007 and completed this spring. It is clear that climate change is happening now.
