According to calculations by Climate Analytics, the broad use of carbon capture technologies could reduce up to 86 gigatons of greenhouse gas emissions less than assumed by 2050. This is because, in practice, CCS plants often capture much less CO2 than would be necessary to reduce emissions effectively. The Intergovernmental Panel on Climate Change (IPCC) defines mitigated emissions („abatement“) as a reduction of 95 percent. However, existing CCS plants often only capture 50 percent or less of emissions.
