On 19 August 2022, the National Development and Reform Commission (“NDRC”), the National Bureau of Statistics (“NBS”), and the Ministry of Ecology and Environment (“MEE“) of the People’s Republic of China (“PRC”) jointly issued the “Implementation Plan on Accelerating the Establishment of a Unified and Standardised Carbon Emission Statistical Accounting System (the “System”)” (the “Plan“).

In light of the “worsening drought crises” and “critically low reservoir conditions” in the Western United States, on Aug. 16, 2022, the U.S. Department of the Interior (“Interior”) announced a number of “urgent actions to improve and protect the long-term sustainability of the Colorado River System.” Assistant Secretary for Water and Science Tanya Trujillo stated

Much ado is being made of recent amendments to the Clean Air Act (CAA) contained in the Biden administration’s budget reconciliation law passed in mid-August, commonly referred to as the Inflation Reduction Act (IRA). And with good reason, as the law includes the most significant changes to the CAA since 1990, and the new sections formally define greenhouse gases (GHGs) as an “air pollutant,” consistent with the Supreme Court’s 2007 decision in Massachusetts v. EPA.

However, the IRA amendments to the CAA do not in fact make significant substantive changes in law. Legally speaking, they can’t, given that the IRA is merely a reconciliation bill through which Congress may only assign funding. More to the point, none of the IRA amendments to the CAA address in any way the limitations the Supreme Court recently placed on EPA’s authority to adopt climate change regulation in West Virginia v. EPA, notwithstanding some characterizations to the contrary.

On August 26, 2022, the US Environmental Protection Agency (EPA) released a pre-publication copy of its much-anticipated proposed rule adding perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) to the list of “hazardous substances” under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). EPA asserts that this regulatory escalation of PFOA and PFOS will facilitate faster cleanup of contaminated sites and reduce exposures to these “forever chemicals.” If finalized, these hazardous substances designations will have significant and immediate impacts on many industries, from creating new reporting obligations to increased compliance, enforcement, and litigation risks related to site cleanup. EPA’s efforts involving PFOA and PFOS fall within the broader, whole-of-agency approach to addressing PFAS first announced in its PFAS Strategic Roadmap and represent its first ever exercise of its authority under CERCLA section 102(a) to designate a hazardous substance.
