Gartner defines the carbon accounting and management software market as applications that facilitate the measurement, management, reduction and reporting of enterprise emissions in accordance with the Greenhouse Gas (GHG) Protocol. These tools enable companies to assess and manage their Scope 1, 2 and 3 carbon emissions from across the enterprise and value chain with varying degrees of granularity, from corporate level to product level. “Carbon” is synonymous with the CO2 equivalent for all types of GHG emissions.
