Environment & Climate One Stop (ECO One Stop)
Expressions of Interest (EOI) for CZM Grants Due October 28!
Submit your ECO One Stop Expression of Interest for the next
round of Coastal Resilience and Coastal Habitat and Water Quality Grants now
through October 28.
The Executive Office of Energy and Environmental Affairs
(EEA) has launched the new Environment & Climate One Stop (ECO One Stop) to
simplify the grant application process for climate resilience and environmental
projects in Massachusetts. 
By consolidating multiple applications into one streamlined
process, ECO One Stop allows applicants to apply to multiple grants through a
single application. 
For Fiscal Year 2027, the applications for both
Massachusetts Office of Coastal Zone Management (CZM) grant programs—Coastal
Resilience and the Coastal Habitat and Water Quality—will be part of ECO One
Stop.
A key component of ECO One Stop is the optional, but highly
recommended, Expression of Interest (EOI). Submitting an EOI allows applicants
to provide a summary of their project idea and receive early feedback from
relevant grant program staff before the formal application period begins in
early 2026. 
EOIs are due by October 28 at 11:59 p.m. and can be
submitted through this simple online form: https://www.mass.gov/info-details/eco-expression-of-interest
Potential applicants can submit up to four EOIs (i.e., four
project ideas).
For additional information, see the new ECO One Stop
website, which also includes an FAQ page:

The Request for Responses (RFR) for ECO One Stop—which will
serve as the RFR for both CZM Coastal Resilience and Coastal Habitat and Water
Quality Grants—will be released in early 2026. 
Applications will be submitted through EEA’s Grants
Management System (GMS): https://greenhub.appianportals.com/applicants-portal
