Who We Are
The District Department of the Environment (DDOE) is the leading authority on energy and environmental issues affecting the District of Columbia. Using a combination of regulations, outreach, education, and incentives, our agency administers programs and services to fulfill our mission. We work collaboratively with other government agencies, residents, businesses, and institutions to promote environmentally responsible behavior that will lead to a more sustainable urban environment.

Among their many responsibilities are issuing permits, monitoring environmental conditions, providing funding and technical assistance, assessing environmental risks, developing policies, inspecting facilities, enforcing environmental regulations, working with other entities to solve everyday environmental issues, and informing and educating the public on local environmental trends and their benefits.
The DDOE team promotes public and environmental health by implementing and enforcing District and Federal laws and regulations. We recognize that strong and healthy communities are central to the District’s economic prosperity, and work daily to protect the environment in which its people live, work and play.
