Offset NowHow We Calculate Your Offset
Our carbon calculator uses internationally recognized emissions factors to estimate your carbon footprint based on your energy consumption, transportation habits, and air travel.
Emissions Factors
- Electricity: Based on your country’s grid emissions factor (kgCO₂e/kWh)
- Natural Gas: 0.184 kgCO₂e per kWh
- Vehicle: Based on your vehicle type and fuel (kgCO₂e per km)
- Flights: Short: 0.2 tonnes, Medium: 0.8 tonnes, Long: 2.0 tonnes, Extended: 3.0 tonnes
Offset Cost Calculation
We calculate your offset cost at £12 per tonne of CO₂e, with a minimum offset donation of £24 per year. This cost covers the full expense of implementing, monitoring, and verifying carbon reduction projects.

Our calculator uses internationally recognized emissions factors from sources like the UK Government’s GHG Conversion Factors and the International Energy Agency. While it provides a good estimate of your carbon footprint, actual emissions may vary based on specific circumstances.
The minimum offset covers the cost of implementing, monitoring, and verifying even small-scale carbon reduction projects. This ensures that every offset contribution makes a tangible difference and supports project sustainability.
Your offset donation is directed to our portfolio of Gold Standard-certified projects. At least 85% of your contribution goes directly to project implementation, with the remainder covering verification, administration, and monitoring costs.
Yes, you can choose to offset any portion of your carbon footprint. We encourage you to offset as much as possible, but any contribution helps support our climate projects.
