Environmental protection is at the core of a strong and healthy community. Carl supports legislation to address environmental issues, such as pollution-induced asthma and renewable energy. Carl believes that improving public transportation can help both the environment and the economy. Building our mass transit system will create jobs, while the increased use of public transportation will lead to cleaner air. In particular, Carl supports extension of the MBTA Green Line, and will fight to see the state uphold its legal obligations to Medford and Somerville by getting this project underway.
