Estimate Scope 1-2-3 emissions, check SEC/CSRD applicability, and get reduction recommendations.
Emission factors are US national averages from EPA. Scope 3 is estimated using industry ratios and should not replace a full supply chain audit. Carbon intensity benchmarks are approximate. This tool is for screening purposes only — professional carbon accounting is recommended for regulatory compliance.

Frequently asked
What emission scopes does the carbon calculator measure?
It covers all three GHG Protocol scopes: Scope 1 (direct combustion—company vehicles, on-site heating), Scope 2 (purchased electricity—multiply kWh by your grid's emission factor, e.g., 0.386 kg CO2/kWh US average), and Scope 3 (supply chain, commuting, business travel). Output is in metric tons CO2e with category breakdowns.
How do I use the results for ESG reporting?
The output aligns with GRI 305, CDP, and TCFD disclosure frameworks. Export your Scope 1-3 inventory as a structured report suitable for annual sustainability disclosures, investor questionnaires, or B Corp certification applications. Over 90% of S&P 500 companies now publish Scope 1 and 2 data; Scope 3 reporting is growing rapidly.
