Therefore, irreversible damage has already started to occur. In order to stop these developments, the Paris Agreement of 2015 set the goal of limiting global warming to a maximum of 1.5°C by the end of the century. This results in a fixed carbon emissions budget, i.e. an upper limit for global emissions that may still be released. Including a small risk buffer for self-reinforcing climate change feedbacks or delays in the use of negative emissions, a maximum of roughly 300 billion tons of carbon emissions may be emitted worldwide to limit warming in 2100 to 1.5°C with a probability of 67 %. 1 Based on modelled emission pathways from IPCC 2 (with an overview within figure 1) with little or no temperature overshoot of 1.5°C, emissions need to be halved every decade. But instead, in 2021, annual emissions reached a record level of 39 billion tons 3 , so if current trends continue the budget will be exceeded way before 2030 and 1.5°C will be overshot. This increases the need for an even more rapid transition later on as well as the use of atmospheric carbon removal, i.e. negative emission solutions to bring back warming to 1.5°C by the end of this century. 4 Figure 1: Global CO 2 emissions pathways (source: IPCC AR6) 1 Source: IPCC Assessment Report 6 Working Group I Table SPM.2. 2 Intergovernmental Panel on Climate Change. 3 Source: U.N.
