Choose efficiency first
Use less energy, improve equipment efficiency and optimise operations before relying on credits.
Use this simple educational calculator to estimate emissions from common activities. Results are indicative, not a verified inventory.
Choose an activity, enter usage and get an indicative CO₂e estimate. For business claims, formal inventories should use recognised greenhouse-gas accounting methods and current local emission factors.
Measure the activity you control.
Reduce emissions at source first.
Address residuals with credible climate finance.
Use less energy, improve equipment efficiency and optimise operations before relying on credits.
Solar, wind and electric mobility can reduce emissions directly when implementation fits your context.
For residual emissions, evaluate carbon projects with strong methodologies, monitoring and verification.
