Climate Liability and Courts

The Supreme Court has agreed to hear ExxonMobil and Suncor Energy’s appeal seeking to move Boulder County’s climate-damages lawsuit into federal court after the Colorado Supreme Court allowed it to proceed. The companies, backed by the Trump administration, argue that state-law suits addressing global emissions threaten a critical national sector and belong in federal court, while Boulder counters that states may remedy in‑state harms from out‑of‑state conduct; the justices have also asked about procedural ripeness and are expected to hear arguments in the fall.
