When you use the CO2 calculator in our app, you answer a series of questions about your lifestyle. We'll match your answers with emissions factors to give you an estimate of your carbon footprint. That way, we can calculate your CO2 emissions. We've put together all the methods and sources used for calculating your carbon footprint in this whitepaper.

The figure we give you is an educated guess based on average figures. Not all the parameters in the calculation can be made without making certain assumptions based on an average and there are many choices that go into the choice of emission factors. Therefore, your result should be taken as an estimate and not an absolute truth.
However, keep in mind that if you use the detailed version of the calculator, you will also get a more accurate figure. Of course, in order not to make the calculator too long, there are still some things we don't ask about, but most of them are included in the detailed calculator.

You may not need one!
But if you sometimes find it a bit difficult to know what you can do to fight climate change, then the Climaider app might be for you. Or if you just want to see how big your climate footprint is or want to learn something new.
We want to make it easy and fun for ordinary people to take climate action. That's why we created Climaider. We've collected all the actions that make the biggest difference for the smallest effort, so it's easy for you to get started with climate action. In the app you can also track your contribution to our climate projects if you are a paying member.
