This article shows that including offsets in climatechange 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.,

The STEO projects that petroleum CO 2 emissions will decline by 4% in 2009, primarily due to declines in transportation sector consumption. Click to enlarge.
Factors contributing to the 7% drop in emissions in 2009. While emissions have declined in three out of the last four years, EIA noted, 2009 was “ exceptional ”. In addition to a decline in gross domestic product (GDP) in 2009 of 2.4%, the energy intensity of the economy (energy consumed per dollar of GDP) declined 2.4%
