Study: Climate targets require huge negative emissions

To achieve the Paris climate targets, negative emissions are necessary. Almost all scenarios show this. The IPCC also considers them to be unavoidable. However, the technologies that can be used to remove carbon dioxide from the atmosphere are expensive and complex, and some of them are still at an early stage of development. This is the conclusion of a recent statement by Scientists for Future (S4F), which examines the possibilities and limitations of negative emission technologies (NET).
