Environmental justice has become an important topic in public policy across the United States. Maine is preparing legal definitions that will guide future environmental decisions and state legislation. The process follows a new state law and includes discussion about pollution, climate change, community protection, and equal access to healthy living conditions for different population groups.
Environmental Justice Definition in Maine
The new law gives Maine about 8 months to prepare official definitions for several environmental terms. These include environmental justice, environmental justice populations, and frontline communities. State agencies will later use these definitions when creating future policies and making environmental decisions.
Earlier versions of the legislation proposed new responsibilities for state agencies, but several parts were removed because legal definitions had not yet been established. Officials explained that unclear language could create uncertainty during decision making and increase the possibility of legal disputes.
Several factors influence the work:
- Maine has a long coastline with different environmental risks.
- Large rural areas require different approaches from urban regions.
- Coastal communities may experience sea level rise earlier than inland areas.
- Population groups have different economic and social conditions.
Because of these differences, officials are developing definitions that reflect conditions found inside the state instead of directly copying rules used elsewhere.

Development of Environmental Justice Policies
The modern environmental justice movement in the United States is often connected with events that happened in 1982. During that year, residents of Warren County, North Carolina, protested against plans to place contaminated soil in a local landfill. The protests became a decisive moment in later discussions about environmental inequality.
Since then, different states have developed their own legal approaches. At present, 7 states have adopted legal definitions related to environmental justice, while other states use similar definitions through environmental agencies or public programs.
Environmental justice generally examines how environmental risks and environmental benefits are shared among different communities. These discussions often include pollution, climate change, industrial development and public health. Policymakers also study whether some communities experience greater environmental burdens because of historical, economic, or geographic conditions.
Different State Approaches

States have created different legal criteria because local conditions are not identical. New Jersey, for example, considers whether at least 35% of households are classified as low income, at least 40% of residents belong to minority or recognized tribal communities, or at least 40% of households have limited English proficiency. These measurements help identify communities that may require additional environmental review.
In March, Massachusetts passed its law with different numerical standards. Neighborhoods with at least 25% of the residents being minorities can be considered for environmental justice but income and access to natural resources can also play a role in the final decision.
Future Policy and Community Protection
Legal definitions alone do not automatically change environmental conditions. They provide a framework that lawmakers and government agencies may use when preparing future regulations. Some states already apply these definitions while reviewing permits for new industrial facilities or evaluating cumulative environmental impacts from several pollution sources.
Maine also plans to include different communities during the consultation process. Environmental specialists, public officials, tribal representatives, and other stakeholders are expected to participate while the definitions are prepared. Discussions may include Indigenous communities, immigrants, people of color, labor union members, coastal residents and other groups affected by environmental conditions.
