Which programme fits your goal
Are these calculators free?
Yes. All tools are free and run in your browser; nothing you enter is stored.
Which emission factors do you use?
India's CEA grid factor for electricity, IPCC defaults for fuels, and UK DESNZ 2025 factors as an approximation for travel. Every factor can be edited.
Can I use the results in my reports?
Use them as screening estimates. For BRSR or audited inventories, use your own records and an assurance provider.
How do trees fit in?
After reducing emissions, trees can balance part of what remains. The trees-to-offset calculator shows how many.
