CARE – Carbon Avoided: Retrofit Estimator
The CARE Tool is used for calculating and comparing the embodied, operating and avoided carbon impacts and benefits of reusing and upgrading existing buildings or replacing them with new construction. About CARE Renovating an existing structure usually has a much lower...
Embodied Carbon in Construction Calculator (EC3)
The Embodied Carbon in Construction Calculator (EC3) tool is a free and easy-to-use tool that allows benchmarking, assessment and reductions in embodied carbon, focused on the upfront supply chain emissions of construction materials. The EC3 tool was incubated at the Carbon...

Bay Area Embodied Carbon Proposal
Status: Completed
The Carbon Leadership Forum supported a collaborative proposal by Marin County, StopWaste, Alameda County, and the Ecological Building Network to establish best practices, specifications and model policies that address the embodied emissions in building materials, starting with concrete. The Carbon Leadership Forum helped the proposal team by collecting 45 signatures for a letter of support, which helped lead to the successful funding of the grant.
The project led to the adoption, on January 1, 2020 of the county’s Bay Area Low-Carbon Concrete Code, the first building code of its kind in the United States. Bruce King, a Carbon Leadership Forum member catalyzed the code’s development to rein in the profligate overuse of carbon-intensive cement in concrete.

Carbon Smart Building Day
Status: Completed
The Carbon Leadership Forum, in collaboration with numerous partners, hosted a day-long conference in San Francisco on September 11, 2018. Affiliated with the Global Climate Action Summit, the conference brought together 300 building industry professionals dedicated to accelerating a global movement toward a Net Zero Carbon built environment.
