The OpenCarbon data exchange format is a standard JSON template for sharing carbon emissions data between applications. The standard is open source so that it can evolve over time to keep up with changing carbon inventory protocols. The OpenCarbon data visualizer app featured on this website reads your city's standardized carbon emissions data and presents it as an interactive graphic. The beauty of open data standards is that they allow greater interoperability of data between computer applications. Once your city's carbon data is in the standard OpenCarbon format, programmers and researchers can use the data to build new tools and analyses.
OpenCarbon is based on the latest carbon accounting protocols for emissions from municipal operations (Local Government Operations Protocol) and from community-wide sources (Global Community Protocol).
