Our department's mission is to enhance the quality of life in Boston by protecting our air, water, and land resources and addressing climate change. 

We are carrying out Mayor Walsh’s vision for environmental protection. We maintain Boston's wealth of historic sites, buildings, landscapes, and waterways.

Our team also takes action on climate change. Boston is committed to reducing the carbon pollution that contributes to climate change and preparing for its impacts. We want to build a more sustainable, resilient, and healthier city now and for future generations of Bostonians.
