Zeng, Sibo, et al. 2019: “Sensitivity of the Global Carbonate Weathering Carbon-Sink Flux to Climate and Land-Use Changes.”

Zeng, Sibo, Zaihua Liu, and Georg Kaufmann. 2019: “Sensitivity of the Global Carbonate Weathering Carbon-Sink Flux to Climate and Land-Use Changes.” Nature Communications 10 (1). https://doi.org/10.1038/s41467-019-13772-4.

‌"Here, we show that there is likely to be a widespread and consistent increase in the global CCSF (ranging from + 9.8% (RCP4.5) to + 17.1% (RCP8.5)) over the period 1950–2100."

Project: Coastal enhanced silicate weathering (ESW)

"Coastal enhanced silicate weathering (ESW) as a negative emissions technology (NET) is an approach that uses the natural process of silicate weathering for the removal of CO2 from the atmosphere."

Kirchner, Julia S., et al. 2020: "Reducing CO2 Emissions of a Coal-Fired Power Plant via Accelerated Weathering of Limestone: Carbon Capture Efficiency and Environmental Safety."

Kirchner, Julia S., Andrew Berry, Frank Ohnemüller, Bernhard Schnetger, Egon Erich, Hans-Jürgen Brumsack, and Karsten A. Lettmann. 2020. “Reducing CO2 Emissions of a Coal-Fired Power Plant via Accelerated Weathering of Limestone: Carbon Capture Efficiency and Environmental Safety.” Environmental Science & Technology. 2020. https://pubs.acs.org/doi/abs/10.1021/acs.est.9b07009.

"Accelerated weathering of limestone (AWL) has been proposed as a tool to capture CO2 from effluent gas streams and store it primarily as bicarbonate in the marine environment. We evaluated the performance of the biggest AWL-reactor to date that was installed at a coal-fired power plant in Germany."

Gattuso, J.-P.; et al. (2019): Opportunities for increasing ocean action in climate strategies

Gattuso, J.-P.; et al. (2019): Opportunities for increasing ocean action in climate strategies. IDDRI, Policy Brief N°02/19.

"In this Policy Brief we assess 18 ocean-based measures to support climate policies and the revision of NDCs in the areas of mitigation and adaptation. Ocean-related measures should not be considered as a substitute for climate mitigation on land, which must also be strongly pursued for the benefit of the atmosphere as well as the ocean."

Smith, Pete; et al. (2019): Land-Management Options for Greenhouse Gas Removal and Their Impacts on Ecosystem Services and the Sustainable Development Goals

Smith, Pete; Adams, Justin; Beerling, David J.; Beringer, Tim; Calvin, Katherine V.; Fuss, Sabine et al. (2019): Land-Management Options for Greenhouse Gas Removal and Their Impacts on Ecosystem Services and the Sustainable Development Goals. In Annu. Rev. Environ. Resour. 44 (1), pp. 255–286. DOI: 10.1146/annurev-environ-101718-033129.

"Land-management options for greenhouse gas removal (GGR) include afforestation or reforestation (AR), wetland restoration, soil carbon sequestration (SCS), biochar, terrestrial enhanced weathering (TEW), and bioenergy with carbon capture and storage (BECCS). We assess the opportunities and risks associated with these options through the lens of their potential impacts on ecosystem services (Nature's Contributions to People; NCPs) and the United Nations Sustainable Development Goals (SDGs)."

Bach, L. T.; et al. (2019): CO2 Removal With Enhanced Weathering and Ocean Alkalinity Enhancement: Potential Risks and Co-benefits for Marine Pelagic Ecosystems

Bach, Lennart T.; Gill, Sophie J.; Rickaby, Rosalind E. M.; Gore, Sarah; Renforth, Phil (2019): CO2 Removal With Enhanced Weathering and Ocean Alkalinity Enhancement: Potential Risks and Co-benefits for Marine Pelagic Ecosystems. In Front. Clim. 1, p. 7. DOI: 10.3389/fclim.2019.00007.

"Humankind will need to remove hundreds of gigatons of carbon dioxide (CO2) from the atmosphere by the end of the twenty-first century to keep global warming below 2°C within the constraints of the global carbon budget. However, so far it is unclear if and how this could be achieved."

Call for Abstracts: The Role of Negative Emission Technologies in Addressing Our Climate Goals

Deadline: 1. March 2019

"It is clear that Negative Emission Technologies (NETs) can never be a wholesale replacement for reducing emissions but may be useful in displacing some energy/emission intensive sectors. It is unlikely that a single NETs proposal can be scaled sufficiently to meet this demand, and a portfolio of approaches may be more feasible. The primary removal methods of focus in this research topic of Frontiers in Climate will include all negative emissions strategies that directly mitigate climate change."
