Der lange Weg bis zu Aussagen in völkerrechtlich bindenden Umweltabkommen zu technischen Eingriffen in das Klimasystem

The long road to statements in international agreements on technical binding environmental agreements on technical interventions in the climate system: The hesitant global climate politics since about 30 years has led – according to the Intergovernmental Panel on Climate Change (IPCC) – to the situation that the goals of the Paris Agreement to the UN Framework Convention on Climate Change can only be reached - besides drastic reductions of greenhouse gas emissions - by Climate Engineering (CE) methods, like carbon dioxide removal and its storage in the Earth’s crust. There is no direct mentioning of CE in the binding parts of UN conventions on the environment. Only the Convention on Biological Diversity has decided in 2010 on a moratorium for large-scale applications of all geoengineering methods and has confirmed it in subsequent COPs.
