Brown University sold 90% of its investments in companies that extract fossil fuels and is liquidating the remainder, President Christina H. Paxson said in a letter to the campus community Wednesday. The University is also investing in wind, solar and possibly renewable natural gas. Ms. Paxson said Brown is making progress on plans to shift a natural gas central heating plant to a sustainable power source. Two near-term options that will be decided by the end of 2020 are converting the plant to burn recycled biofuel or offsetting natural gas by investing in a renewable natural gas project. The wind and solar projects and the switch to biofuel or renewable natural gas will make possible the goal to cut campus greenhouse gas emissions by 75% by 2025. More >>
