State carbon market. No Legislation required.

The Governor of Oregon created a state carbon market without new legislation by relying on existing regulatory structures. Oregon’s 1st foray into carbon market was in 2022, which was halted by courts in 2023, and then the state environmental commission acted by rule making in accord with the court ruling for the 2025 re-launch. Pennsylvania, Maryland, and Vermont are considering creating their own state carbon market.
