Climate law is an emerging part of environmental law. It aims at stabilising the concentration of greenhouse gases in the atmosphere, especially CO2, at a certain level to prevent dangerous anthropogenic interference with the climate system (Art 2 UN Framework Convention on Climate Change). In the light of the Paris Agreement, this means limiting global warming to 1.5 but no more than 2 degrees Celsius compared to pre-industrial levels.
Climate protection and adaptation measures are at the heart of climate law. On the one hand, protective measures typically aim to mitigate the causes of climate instability by reducing greenhouse gas emissions or removing GHGs from the atmosphere. On the other hand, adaptation policy concerns measures to adjust to already current and predicted impacts of climate change.
Climate law is embedded in a multi-level system of international, European and national regulations and is closely interlinked with other areas of law, such as constitutional and administrative law, but also civil or tax law.
