Make a donation
You would like to support us, but you don’t have the money to become a regularly paying member? Help us with your donation!
Just decide on the amount you would like to give. You can donate any amount on money, regardless the current price of an emission allowance. We will collect the money we receive until we can buy and delete new emission allowances.
How much to give
To estimate how much CO2 you produce in your daily life (home, travels, consumption), you can use a carbon calculator, such as the WWF Footprint calculator. If you are based in Germany, we suggest you to use the CO2 calculator of the German Federal Environmental Agency (UBA).
If you want to know the current price of an emission allowance please click here. Please consider that we have to pay taxes and charges, wherefore the actual price to delete a ton is approximately 25 percent higher than the EUA price at the market.
Choose your way
As soon as you have decided how much to give, you have got two options: transfer the money to our bank account or donate immediately and safely online with PayPal or ClickandBuy!
