Rickels, W.; et al. (2019): (Mis)Conceptions about Modeling of Negative Emissions Technologies

Rickels, Wilfried, Christine Merk, Fabian Reith, David P Keller, and Andreas Oschlies. 2019. “(Mis)Conceptions about Modeling of Negative Emissions Technologies.” Environmental Research Letters 14 (10): 104004. https://doi.org/10.1088/1748-9326/ab3ab4.

‌"Here, we show the results from an anonymous expert survey, including 32 Earth-System-Model (ESM) experts and 18 Integrated-Assessment-Model (IAM) experts, about the role of NETs in future climate policies and about how well the various technologies are represented in current models. We find that they strongly support the view that technology portfolios are required to achieve negative emissions, however, the responses show that the number and range of NETs that can be assessed in IAMs is small and that IAMs and ESMs are rather applied to analyze technologies separately than in combination."

Paustian, Keith, et al. (2019): “Soil C Sequestration as a Biological Negative Emission Strategy.”

Paustian, Keith, Eric Larson, Jeffrey Kent, Ernie Marx, and Amy Swan. 2019. “Soil C Sequestration as a Biological Negative Emission Strategy.” Frontiers in Climate 1 (October). https://doi.org/10.3389/fclim.2019.00008.

‌"In addition to carbon dioxide removal potential, increases in soil organic matter/soil C content are highly beneficial from the standpoint of soil health and soil fertility. Practices to increase soil C stocks include well-known, proven techniques, or “best management practices” (BMP) for building soil carbon."

Carbon Brief: Guest post by Prof. Duncan McLaren: The problem with net-zero emissions targets

"However, our newly published research – based on findings from expert interviews and stakeholder deliberations – suggests that combining emissions reductions and negative emissions into a single target of reaching “net-zero” may create problems. These could include delayed emissions cuts, but also insufficient focus on developing negative emissions technologies."

Project: “Solid Carbon: A Climate Mitigation Partnership Advancing Stable Negative Emissions”

"The $1.5 million, four-year PICS Theme Partnership entitled “Solid Carbon: A Climate Mitigation Partnership Advancing Stable Negative Emissions” brings together researchers from Canada, the United States and Europe. The team aims to combine state-of-the-art technologies in a way that has never been conceived until now, to deliver safe and reliable carbon dioxide (CO2) removal."

Buck, Holly Jean (2019): Challenges and Opportunities of Bioenergy With Carbon Capture and Storage (BECCS) for Communities

Buck, Holly Jean (2019): Challenges and Opportunities of Bioenergy With Carbon Capture and Storage (BECCS) for Communities. In Current Sustainable/Renewable Energy Reports. DOI: 10.1007/s40518-019-00139-y.

"BECCS cannot be viewed on just the community scale without considering how national and global scales influence system design. The limited research relevant to BECCS on the community scale looks at public acceptance or social license, rather than opportunities for communities. Future research can move beyond “social impact” to study “social demand” for BECCS, and identify opportunities for communities along the farm-to-underground or farm-to-product chain."

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)."

Lefebvre, D. A., et al. (2019). Assessing the potential of soil carbonation and enhanced weathering through Life Cycle Assessment: A case study for Sao Paulo State, Brazil

Lefebvre, D. A., Goglio, P. C. D., Williams, A., Manning, D., Azevedo, A., Bergmann, M., Meersmans, J., Smith, P. (2019). Assessing the potential of soil carbonation and enhanced weathering through Life Cycle Assessment: A case study for Sao Paulo State, Brazil. Journal of Cleaner Production, 233, 468–481. doi: 10.1016/j.jclepro.2019.06.099.

"In this paper, we investigate the established mining industry that extracts basaltic rocks for construction from the Paraná Basin, Sao Paulo State, Brazil. Through a Life Cycle Assessment, we determine the balance of carbon dioxide emissions involved in the use of this material, the relative contribution of soil carbonation and enhanced weathering, and the potential carbon dioxide removal of Sao Paulo agricultural land through enhanced weathering of basalt rock."

Goglio, P., et al. (2019). Advances and challenges of life cycle assessment (LCA) of greenhouse gas removal technologies to fight climate changes

Goglio, P., Williams, A., Balta-Ozkan, N., Harris, N., Williamson, P., Huisingh, D., Zhang Z., Tavoni, M. (2019). Advances and challenges of life cycle assessment (LCA) of greenhouse gas removal technologies to fight climate changes. Journal of Cleaner Production, 118896. doi: 10.1016/j.jclepro.2019.118896.

"In this article, challenges for LCA are reviewed and discussed together with some alternative approaches for assessment of GGRTs. In particular, GGRTs pose challenges with regards to the functional unit, the system boundary of the LCA assessment, and the timing of emissions."

Hilaire, Jérôme; et al. (2019): Negative emissions and international climate goals—learning from and about mitigation scenarios

Hilaire, Jérôme; Minx, Jan C.; Callaghan, Max W.; Edmonds, Jae; Luderer, Gunnar; Nemet, Gregory F. et al. (2019): Negative emissions and international climate goals—learning from and about mitigation scenarios. In Climatic Change. DOI: 10.1007/s10584-019-02516-4.

"Most recent evidence stresses the importance of future socio-economic conditions in determining the flexibility of NET deployment and suggests opportunities for hedging technology risks by adopting portfolios of NETs. Importantly, our thematic review highlights that there is a much richer set of findings on NETs than commonly reflected upon both in scientific assessments and available reviews. "
