What’s going on with environmental issues in California in 2026?

California’s climate and water agenda in 2026 is ambitious on paper but complicated in practice. The state is setting historic water supply targets, extending its carbon market, and pushing aggressive decarbonization — while implementation of major programs runs years behind, bond money is getting diverted, and costs are rising fast enough to fracture the political coalition behind climate action. Some Democrats are openly breaking from policies they recently voted for. Meanwhile, federal rollbacks are forcing California to harden its own rules and fight battles in court against the Trump Administration. The underlying tension isn’t really about any single fight — it’s about whether California can hold together the political will to actually deliver on commitments it has already made.
