Our Mission

The Environmental League of Massachusetts is committed to combating climate change and protecting our land, water, and public health. By creating diverse alliances and building the power of the environmental community, we use our collective influence to ensure Massachusetts is a leader in environmental and economic sustainability.

What We Do

The Environmental League of Massachusetts (ELM) is a nonprofit educational and advocacy organization, supported by a combination of individual and foundation philanthropy, dues from citizens and organization members, and proceeds from special events.

We focus our resources on the state level, where we believe that our knowledge, expertise and reputation allow us to have the strongest impact. We also network and collaborate with a variety of leaders in business and government as well as with other environmental nonprofits to achieve effective results.

Past to Present

Advocates for responsible environmental policy since 1898!

Originally established as the Massachusetts Forestry Association, the organization continually became involved with related environmental issues. Reflecting our broadened scope, the name was changed in 1993 to the Environmental League of Massachusetts.

ELM’s advocacy efforts encompass climate issues, protection of habitats and species, land preservation, development of urban parks, smart-growth planning, protection of water resources, and curtailing exposure to toxins in everyday living — the whole range of modern environmental issues that have an impact on our health and quality of life in Massachusetts.
