Environmental advocates warn of pitfalls in state climate plan March 01 2021 Group says Oregon must live up to goals Gov. Brown set after 2020 GOP legislative walkouts. As Oregon begins to put together its plan to cap greenhouse gases, environmental advocates say the public needs to weigh in to hold everyone to the eventual goal of 80% reduction from 1990 levels by 2050 — or more. Gov. Kate Brown issued her executive order almost exactly one year ago, after Republican walkouts in both chambers blocked votes on legislation (House Bill 2020) that would have set that ultimate target and an interim goal of 45% by 2035. Democratic leaders then adjourned the 2020 session.
