Petition for Rulemaking on the Subject of Greenhouse Gases and Their Impact on Public Health and Welfare, in Connection with EPA’s 2009 Endangerment Finding

In February 2017, two organizations submitted a petition to EPA asking the agency to initiate a rulemaking proceeding on the subject of the public health and welfare impacts of greenhouse gases. The organizations contended that “evidence has continued to mount” contradicting EPA’s 2009 endangerment finding that greenhouse gases threatened public health and welfare. In particular, the groups argued that there had been no statistically significant atmospheric warming despite continued increases in carbon dioxide levels; that recent changes in global temperatures were not unusual; and that accumulation and refinement of data demonstrated that the atmosphere was less sensitive to carbon dioxide forcing than predicted by climate models. The petition said that growing evidence showed EPA’s regulations would have “no discernible climate impact” and that the rationale for the 2009 endangerment finding therefore required reexamination.
