U.S. EPA is seeking comments on a significant rulemaking proposal that would establish initial major source applicability thresholds for GHG emissions under the Clean Air Act's PSD (Prevention of Significant Deterioration) and Title V programs at 25,000 tons per year on a CO2-equivalent basis. It justifies a departure from existing statutory thresholds - which are substantially lower - "[b]ased on the long-established judicial doctrines of 'absurd results' and 'administrative necessity.'" It appears that concerns expressed by industry that U.S. EPA will move on this issue to force Congress to act were well founded.

Question: What will be the impact on global temperatures if the proposed rule is finalized?
