For climate change and global warming, it is irrelevant where greenhouse gases are produced. Nor does it matter where the emissions are reduced. The main thing is to reduce them. That is why companies can, for example, offset their CO2 emissions in another country or region. If you fly from Germany to the USA, you can offset the CO2 emissions caused by donating to a climate protection project in Asia, for example.
For CO2 offsetting, it is calculated how much emissions are caused by a specific activity. For example, the production of coffee cups, a car journey, or the electricity and heat supply of an office building. Certificates or emission reduction credits are issued for the number of emissions, which are used to offset the same amount of emissions in climate protection projects. It is important for the significance of climate compensation that these climate protection projects were created "on top" as a climate protection measure and that they would not exist at all without the principle of CO2 compensation.
