How we work
Carbon Retirement is an alternative way to offset your carbon footprint. We allow you to directly influence industrial carbon emissions in Europe.
Carbon Retirement uses your money to purchase carbon allowances out of the EU Emission Trading Scheme. This is the EU's central tool for cutting carbon emissions. It works by giving heavy industry a fixed number of allowances to emit greenhouse gases.
Each time we buy an allowance, we retire it. Retiring permanently removes allowances from the market so they are unavailable to the industries that would otherwise use them as rights to pollute. You buy emissions out of the system.
This is a good way to offset because:
| Traditional offsetting | Carbon Retirement | ||
|---|---|---|---|
![]() | The size of the reduction is hard to measure. | ![]() | Emissions in the EU Emission Trading Scheme are accurately measured. |
![]() | It's hard to know whether your money will achieve something that wouldn't have happened anyway. | ![]() | Carbon Retirement always creates new reductions. |
![]() | Reductions are made in the developing world, while emissions at home remain high. | ![]() | All reductions are made within the European Union. |
![]() | The reduction may be reversed in the future. | ![]() | All emissions are permanently removed from the market. |

Use the options above to work out how many tonnes of carbon you want to retire. You can calculate the emissions associated with flights, driving, and the energy you use at home. If you already know how many tonnes you want to retire, you can enter it directly.
The calculator follows recognised government guidelines. It uses data published by the Department for Environment, Food and Rural Affairs.
