What is the ECO One Stop?
The ECO One Stop is a joint application that provides eligible grant applicants with a simplified, single point of entry for various climate and environmental resilience grants. This integrated process includes:
- Expression of Interest (EOI): An optional, but highly recommended, initial step to share your project idea and receive early feedback.
- Centralized Grant Application: A single application to be considered for multiple funding opportunities.
- Strategic Funding Identification: EEA will work to match as many projects as possible that advance climate resilience and environmental priorities with the most suitable funding source.
Why did we create the ECO One Stop?
The ECO One Stop is an action created under the ResilientMass Plan aiming to increase access to climate resilience and environmental protection funding across the Commonwealth. This action was informed by feedback from our Community Climate Advisory Council (CCAC), as well as focus groups and surveys conducted with various stakeholders including municipalities, Tribal Governments, regional planning agencies, and nonprofit organizations.

How will ECO One Stop applications be reviewed?

Each grant program’s review team will have access to an applicant’s full application including all general and program-specific questions and attachments. Review teams for different grant programs may use different scoring criteria when evaluating the same applications.
Is a match required for ECO One Stop grants?
Aall of the grants participating in the ECO One Stop require a 10% match of the grant amount through either cash or in-kind contributions. Exceptions to these match requirements apply for Tribal governments and designated rural and small towns.
How do I know which grant programs my project is best suited for?
If you are unsure which program(s) your project is best suited for, you can fill out an Expression of Interest to receive direct feedback from EEA staff on your project and which grant program(s) might be the best fit. Outside of the EOI process, you can review our ECO One Stop Grants Catalogue to learn more information about each of the featured grants to assess which one(s) align best with your project.
