Self-serve GHG emissions calculation—powered by Envizi expertise
Calculate with confidence—without complexity
Not every emissions calculation requires a full accounting platform or custom-built solution. Envizi Emissions Calculations in Excel enables hands-on emissions calculations within familiar spreadsheet environments.
You can populate preconfigured templates with activity data such as energy consumption or fuel use, and embedded formulas will retrieve emissions factors from Envizi’s factor library to calculate results.
This solution provides flexibility and transparency for organizations earlier in their carbon accounting journey. It is ideal for sustainability and ESG analysts, consultants and advisory teams, and finance and operations teams supporting emissions analysis, particularly those taking a do-it-yourself approach or exploring new emissions categories.
