Turn the estimated footprint of a trip into a measurable reduction goal. Enter the underlying activity, emission factors, target percentage, and timeline to see the required total cut, average annual progress, remaining target footprint, and equivalent compounded annual reduction rate.
The required cut is the difference between the current baseline and the desired endpoint. The annual figure is a straight-line planning pace; actual reductions can occur unevenly.
A target is only comparable over time when the boundary, factors, and units are kept consistent or changes are documented.
A 10 t CO₂e baseline with a 30% target over five years requires a 3 t CO₂e total cut, averaging 0.6 t per year, and leaves 7 t at the endpoint.
Use activity data from the same reporting period and emission factors that match the activity, geography, and unit.
It reports carbon dioxide equivalent, so other greenhouse gases may be included when the emission factors already express their combined climate impact as CO2e.
Results can differ because system boundaries, emission factors, allocation methods, and the age of source data may not match.
Use it for planning and screening. Targets used in public claims may need an approved base year and reporting framework. Formal disclosures may require documented factors, organizational boundaries, and independent review.
Update it when activity levels, suppliers, energy sources, travel patterns, emission factors, or carbon prices change materially.
