Phys.org: Why we can't reverse climate change with 'negative emissions' technologies

"Featured prominently in the report is a discussion of a range of techniques for removing 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."

Science: Key climate panel, citing impending crisis, urges crash effort to reduce emissions

"A report released yesterday in Incheon, South Korea, by the Intergovernmental Panel on Climate Change (IPCC) says allowing the planet to warm by more than 1.5°C could have dire consequences, and that a speedy transformation of the world’s energy systems is needed to avoid breaching that limit, which is notably tighter than the target of 2°C cited in the Paris agreement of 2015. “Net [carbon dioxide] emissions at the global scale must reach zero by 2050,” said Valérie Masson-Delmotte, a climate scientist at France’s Alternative Energies and Atomic Energy Commission in Paris and a key participant in drafting the report."

YouTube: Ambitious climate targets – the role of negative emissions

"An animated film about the climate goals of the Paris Agreement 2015 and the role of negative emissions: Can we achieve the "Well-below-2°C" target? 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)."

UNEARTHED: Can negative emissions really save the world?

"Today, climate scientists at the UN’s Intergovernmental Panel on Climate Change warned that the world needs to radically reduce greenhouse gas emissions to keep the planet within 1.5 degrees of warming by the end of the century. Worried? The boss of a company which has pioneered a way of sucking carbon emissions out of the air wants you to know he’s here to help."

Wohland, J.; et al. (2018): Negative emission potential of Direct Air Capture powered by renewable excess electricity in Europe

Wohland, J.; Witthaut, D.; Schleussner, C. (2018): Negative emission potential of Direct Air Capture powered by renewable excess electricity in Europe. In: Earth's Future. DOI: 10.1029/2018EF000954.

"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."

Nature: Don’t deploy negative emissions technologies without ethical analysis

"The IPCC report will confirm an open secret: in the light of growing emissions, targets for mitigating climate change increasingly depend on ‘negative emissions technologies’ that suck carbon dioxide out of the atmosphere. Staying within 2 °C could mean extracting billions of tonnes of CO2 this century."

Forbes: Negative Emissions Technologies: Has their time arrived?

"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."

CarbonBrief: Why BECCS might not produce ‘negative’ emissions after all

"Bioenergy crops with carbon capture and storage (BECCS) is, perhaps, the most prominent of the various negative emissions techniques. There are many attractive features, since this technology would provide energy – thus reducing our need for fossil fuels – and remove CO2 from the atmosphere at the same time."
