The City of Boston has pledged to be carbon neutral by 2050. Researchers in the Institute for Sustainable Energy and the Department of Earth and Environment are assessing potential technologies and policies that reduce greenhouse gas emissions across the energy, buildings, transportation, and waste sectors in the City. Social equity is a key cross-cutting theme. This work is a collaborative effort with the City of Boston and the Boston Green Ribbon Commission, and it will inform the City’s upcoming Climate Action Plan update.
