This Article, adapted from the Climate Science and Law for Judges Curriculum, examines the status and viability of judicial remedies in climate change litigation. It focuses on climate cases that are seeking science-based remedies specifically related to climate mitigation (actions to reduce greenhouse gas emissions or draw down atmospheric carbon) and climate-change adaptation (actions to reduce the negative impacts of climate disruption on human and natural communities).

In June 2022, in West Virginia v. Environmental Protection Agency, the U.S. Supreme Court announced that on “major questions” the U.S. Congress must legislate with far more clarity and specificity than previously demanded. The Court held the U.S. Environmental Protection Agency (EPA) may regulate power plant carbon emissions in traditional ways, but the novel approach taken in the Clean Power Plan required clearer authorization than Congress had provided. Six weeks later, Congress enacted the Inflation Reduction Act (IRA).

The Inflation Reduction Act and Federal Buy Clean Initiative have each inspired states and municipalities to regulate embodied carbon (Scope 3) using “Buy Clean” policies and legislation. Reducing embodied carbon has become mainstream, and environmental product declarations (EPDs) have surfaced as the tool. Are EPDs alone enough? Is the compliance timeline sufficient? On February 1, 2023, the Environmental Law Institute hosted a panel of experts that provided an update on Buy Clean policy, green funding, the status of carbon emissions, and a primer on EPDs.
