In this technical note, researchers at Climate Policy Initiative/Pontifical Catholic University of Rio de Janeiro (CPI/PUC-Rio), analyze the legislative process of the new Concessions Law bill from a social and environmental perspective. They recommend items that could be incorporated into the bill to head off potential conflicts currently handled later in the project life cycle — notably during the environmental licensing procedure — and which would foster bidding on more robust, higher quality projects, promoting safer investments, and ensuring social and environmental protections.
