In 2023, California passed two landmark laws—SB 253, the Climate Corporate Data Accountability Act; and SB 261, the Climate-Related Financial Risk Act—that will require large public and privately-held entities doing business in California to comply with sweeping disclosure requirements regarding their direct and indirect greenhouse gas emissions and their climate-related financial risks. California subsequently passed SB 219, which updated certain deadlines and requirements of the laws (collectively, the “Climate Disclosure Laws”).

The Supreme Court declined to hear two key federal environmental enforcement cases, effectively leaving in place lower court rulings that allow for broad private citizen enforcement under the Clean Water Act and Clean Air Act. Because of the Court’s denials, citizen plaintiffs remain free to pursue enforcement cases in the absence of governmental enforcement, thus companies remain at risk of being sued by active watchdog citizen groups.

Supplemental Environmental Projects (SEPs) are voluntary, environmental or public health projects that parties subject to environmental enforcement proceedings can propose as part of an administrative, civil, or criminal settlement. SEPs are unique and used specifically in environmental enforcement cases in part because (1) many environmental law statutes do not require a showing of harm to prove a violation; thus, redressing harm, outside of equitable relief, is not usually statutorily required; and (2) pollution is a public harm that is hard to redress, both individually and collectively.
