The proposed Finding erroneously suggests that Intergovernmental Panel on Climate Change (IPCC) predicts an increase in both crop and forest production in the U.S. (e.g., pg. 28 lines 21 and 34 of the Proposed Finding, pg 80 line 26, page 87 line 9). The IPCC findings refer to North America, not the U.S.
EPA limits solicitation of comment on the proposal to the simple statements on page six to the effect that it seeks comment on all aspects of this action (data, methodology, and major legal and policy considerations). While this is efficient and legally sufficient, the agency may want to highlight a few key areas in which
In this draft proposal, EPA finds under Clean Air Act (CAA) section 202(a) that (1) “air pollution” in the form of the global mix of six greenhouse gases (or the GHGs) may be reasonably anticipated to endanger public health and welfare (the endangerment finding); and (2) emissions of an “air pollutant” in the form of
There is some concern that an endangerment finding, and some of the language used to support the finding, will make it more difficult to comply with NEPA and other environmental planning statutes. This finding and the associated emission standards for these six greenhouse gases.
To the extent that climate change alters our environment, it will create incentives for innovation and adaptation that mitigate the damages from climate change. The document should note this possibility and how it affects the likely impacts of climate change.
EPA should explain whether it considered a finding that methane and the other four nonCO2 GHGs do in fact contribute to climate change, based on their higher warming potential, but that overriding policy concerns make such a finding infeasible concerning CO2. Because methane and the other four non-CO2 GHGs are either already regulated under the
