Climate neutrality can be achieved if CO₂emissions are reduced to a minimum and all remaining CO₂emissions are offset with climate protection measures. If climate-damaging greenhouse gases are completely avoided or if gases that have already been emitted are saved elsewhere, this is referred to as "climate-neutral".
In contrast to air pollution, it does not matter for the climate where greenhouse gases enter the atmosphere and where they are reduced. What is important is that global emissions decrease overall.
This means a company in Germany or Switzerland can also become climate neutral by supporting international climate protection projects. This possibility is provided via the Clean Development Mechanism (CDM) of the Kyoto Protocol.
