Carbon Brief: Geoengineering carries ‘large risks’ for the natural world, studies show

"Reducing the impacts of human-caused climate change through the use of bioenergy with carbon capture and storage – better known as BECCS – could have major consequences for wildlife, forests and water resources, a new study shows."

Heck, Vera; et al. (2018): Biomass-based negative emissions difficult to reconcile with planetary boundaries

Heck, Vera; Gerten, Dieter; Lucht, Wolfgang; Popp, Alexander (2018): Biomass-based negative emissions difficult to reconcile with planetary boundaries. In Nature Climate change 10, p. 105007. DOI: 10.1038/s41558-017-0064-y.

"Roadmaps and socio-economic scenarios compatible with a 2 °C or 1.5 °C goal depend upon NE via bioenergy with carbon capture and storage (BECCS) to balance remaining GHG emissions. However, large-scale deployment of BECCS would imply significant impacts on many Earth system components besides atmospheric CO2 concentrations. Here we explore the feasibility of NE via BECCS from dedicated plantations and potential trade-offs with planetary boundaries (PBs) for multiple socio-economic pathways. We show that while large-scale BECCS is intended to lower the pressure on the PB for climate change, it would most likely steer the Earth system closer to the PB for freshwater use and lead to further transgression of the PBs for land-system change, biosphere integrity and biogeochemical flows."

Yamagata, Yoshiki; et al. (2018): Estimating water–food–ecosystem trade-offs for the global negative emission scenario (IPCC-RCP2.6)

Yamagata, Yoshiki; Hanasaki, Naota; Ito, Akihiko; Kinoshita, Tsuguki; Murakami, Daisuke; Zhou, Qian (2018): Estimating water–food–ecosystem trade-offs for the global negative emission scenario (IPCC-RCP2.6). In Sustain Sci 28, p. 113. DOI: 10.1007/s11625-017-0522-5.

"In this study, we assess the impact of BECCS deployment scenarios on the land systems including land use, water resources, and ecosystem services. Specifically, we assess three land-use scenarios to achieve the total amount of 3.3 GtC year−1 (annual negative emission level required for IPCC-RCP 2.6) emission reduction by growing bioenergy crops which requires huge use of global agricultural and forest lands and water."

Honegger, Matthias; Reiner, David (2017): The political economy of negative emissions technologies. Consequences for international policy design

"n order to understand whether NETs can provide a significant contribution to mitigation, financial incentives are needed that allow implementing the most attractive NET activities at the global scale. We see the market mechanism under Article 6.4 of the Paris Agreement – colloquially called ‘Sustainable Development Mechanism’ – as a possible cornerstone of such a policy instrument. While initially NETs will not be competitive on the free market, the mechanism can facilitate bilateral financial transfers for NETs, where mitigation units accrue to the financier."

Geoengineering Monitor: Failure of Kemper County “clean coal” plant casts more doubts on BECCS

"The project’s failure should cast serious doubts on the prospects of both “clean coal” as well as Bioenergy with Carbon Capture and Storage (BECCS) – the current star child of techno-fix solutions to climate change."

van Vuuren, Detlef P.; et al. (2017): Open discussion of negative emissions is urgently needed

van Vuuren, Detlef P.; Hof, Andries F.; van Sluisveld, Mariësse A. E.; Riahi, Keywan (2017): Open discussion of negative emissions is urgently needed. In Nat. Energy 2 (12), pp. 902–904. DOI: 10.1038/s41560-017-0055-2.

"Although nearly all 2 °C scenarios use negative CO2 emission technologies, only relatively small investments are being made in them, and concerns are being raised regarding their large-scale use. If no explicit policy decisions are taken soon, however, their use will simply be forced on us to meet the Paris climate targets."

Wired: The Dirty Secret of the World’s Plan to Avert Climate Disaster

"In 2014 Henrik Karlsson, a Swedish entrepreneur whose startup was failing, was lying in bed with a bankruptcy notice when the BBC called. The reporter had a scoop: On the eve of releasing a major report, the United Nation’s climate change panel appeared to be touting an untried technology as key to keeping planetary temperatures at safe levels. The technology went by the inelegant acronym BECCS, and Karlsson was apparently the only BECCS expert the reporter could find."

Bioenergy Insight: Bioenergy combined with CCS will help UK to transition to low-carbon energy economy, expert says

"Bioenergy technologies combined with carbon capture and storage (CCS) can play a significant role in the UK’s future UK energy system, according to Energy Technologies Institute (ETI) strategy manager for bioenergy Hannah Evans. The ETI is a UK-based company formed from global industries and the UK government. It was formed in 2007, but its programme is officially ending at the end of this year."

IFSA Blog: Toward safe, effective, and sustainable use of negative emissions approaches

"At COP 23 most ideas focus on reducing GHG emissions in order to achieve the goals of the Paris Agreement. A much less widely discussed approach is to make use of negative emissions that can occur mostly in the field of Forestry/ Forest Conservation and Agriculture. Negative emissions do as well occur in other fields of land uses, but not in equally significant measures as the above-mentioned land uses do. "

Negative CO2: Myths and facts about negative emissions

"Some argue that developing carbon negative technologies gives us permission to slack away, but we are actually slacking away if we do not consider CO2 removal"
