This document summarizes the key developments related to greenhouse gas regulations from 2009-2010 across four fronts: congressional efforts, international efforts, efforts by federal agencies, and court rulings. It discusses major climate change bills considered by Congress, international agreements like the Copenhagen Accord, EPA regulations setting emissions standards and reporting rules, and key court decisions allowing federal common law nuisance claims against greenhouse gas emitters to proceed.

2. "Lurking behind Defendants' arguments is this salient question: What exactly is U.S. 'policy' on greenhouse gas emissions? At one point in their briefs, Defendants acknowledge that this country's official policy and Congress's strategy is to reduce the generation of greenhouse gases. Elsewhere, they point to a policy of research as a prelude to formulating a coordinated, national policy. They also assert that U.S. policy is ' not to engage in unilateral reduction of domestic emissions' (relating, in particular, to the international arena). These variegated pronouncements underscore the point that there really is no unified policy on greenhouse gas emissions." Connecticut v. American Electric Power Co. , 582 F.3d 309, 331-32 (2d Cir. 2009)
