negative emissions

The Paris Agreement set the international goal of limiting global warming to 1.5°C. To achieve this, it is essential to rapidly reduce greenhouse gas emissions towards zero. Additional measures are needed to remove CO2 from the atmosphere, such as reforestation. However, UBA advises against betting on untried, risky technologies.

A number of ideas have emerged in recent years for potential interventions in the climate system to counteract global warming. What these so-called geoengineering measures all have in common is that they harbour risks for humans and the environment and can have a global impact. They should therefore also be regulated globally.
