The CARE Tool estimates the operational and embodied carbon emissions associated with reusing and upgrading an existing building or replacing it with new construction. The CARE Tool can be used by policymakers, planners, building owners, developers, heritage building officers, architects, and others who are interested in a pre- or early-design, high-level assessment of the total carbon emissions of building reuse versus replacement.
