"Featured prominently in the report is a discussion of a range of techniques for removing carbon dioxide from the air, called Carbon Dioxide Removal (CDR) technologies or negative emissions technologies (NETs). The IPCC said the world would need to rely significantly on these techniques to avoid increasing Earth's temperatures above 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, compared to pre-industrial levels."

Do we need so-called »negative emissions« in order to achieve this ambitious goal? What methods are considered to remove CO2 from the atmosphere? A film produced by the Priority Programme 1689 "Climate Engineering" of the German Research Foundation (DFG)."

"Our results show that negative emissions of up to 500 MtCO₂/y in Europe may be achievable by using renewable excess energy only. Electricity systems with high shares of volatile renewables will induce excess generation events during which electricity is cheap thereby lowering the operational costs of DAC. If investment costs can be sufficiently reduced, this may render very energy intensive but highly flexible technologies such as DAC viable."

"The FUTURE Act has also for the first time allowed tax credits for negative emissions technologies (NETs) like direct air capture projects, thus creating opportunities for a systemic shift that can drive new partnerships between carbon management organizations and the energy industry. These technologies are advancing rapidly, their cost is dropping and the FUTURE Act would seem to signal that the time is right."
