Not all the carbon emissions can be reduced, so, we should find a way to compensate for it. The most common and simple way to offset CO2 is planting trees or participating in any other compensation project.
You can do it with your resources or pay someone – there are many organizations to plant a tree on your behalf. Depending on a region,
you can also participate in a variety of compensation projects – for example, solar ovens for countries that got a lot of sunlight.
Always check the material realization of your investments – it should be countable and clear.
