Project Areas
The City is interested in climate technology that will advance Boston's climate goals. These climate goals include:
- reducing community-wide carbon emissions by 50% in 2030 and 100% in 2050
- reducing municipal emissions by 60% in 2030 and 100% in 2050
- implementing coastal resilience and adaptation projects to close all near-term pathways
- reducing localized temperatures and increasing access to cooling resources
- reducing disruption and damage from severe precipitation.
Priority project areas include urban heat mitigation and equitable cooling access, flood resilience, and technologies that address broader urban resilience challenges. We also welcome building technologies that support large-scale retrofitting and reduce embodied carbon.
