What is the ECO One Stop?

The ECO One Stop provides eligible applicants with a simplified, single point of entry for various climate and environmental resilience grants. This integrated process includes:

  • 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 with the most suitable funding source.
