Calculate greenhouse-gas emissions in chat with published emission factors. Each answer shows the factor, its source and edition, and the formula. Electricity (Scope 2, location-based), fuel combustion (Scope 1), business flights and freight (Scope 3) use the national factor for the country you give. No country is ever assumed: without one, or for a fuel or unit the factor library cannot price, the tool says why and what to send instead. For goods exported to the EU, look up the CBAM default value for a CN code and country of origin, with the year's mark-up, from the European Commission's published tables. For Indian listed companies, get what SEBI's BRSR Core asks for in its greenhouse-gas footprint attribute and the assessment or assurance timeline, with the source. Nothing is stored unless you ask to save your calculations. Saved calculations are kept under a private link for 14 days, where you can view them or bring them into a ZeroCarbon workspace.
