C2GTalk: What role can nature-based approaches play in addressing the climate crisis?

"Governance is a key element in ensuring that nature-based approaches to addressing the climate crisis support ecological functions, are sustainable, and produce co-benefits, said Manuel Pulgar-Vidal during a C2GTalk interview. Ultimately, he stressed, any intervention—whether nature- or technology-based—can only be considered if it is based on a strong commitment to reduce carbon dioxide emissions."

Ghidoni, Riccardo; et al. (2021): Governing Climate Geoengineering: Side-payments are not enough

Ghidoni, Riccardo; Bosetti, Valentina; Tavoni, Massimo; Abatayo, Anna (2021): Governing Climate Geoengineering: Side-payments are not enough. Available online at https://ssrn.com/abstract=3790706.

"Through a laboratory experiment on a public good-or-bad game, we study whether side-payments can address this governance problem. While theoretically effective, our experimental results show only a modest impact of side-payments on outcomes, especially in a multilateral setup. Replacing unstructured bilateral exchanges with a treaty framework simplifies the action space and performs moderately better."

C2G: An interview with Ambassador Franz Perrez How can multilateral processes shape the governance of climate-altering approaches?

"Addressing the global challenge of governing climate-altering approaches through multilateralism is not just possible but necessary, said Ambassador Franz Perrez during a C2GTalk interview. In the end, he says, it is in everyone’s best interest to build a common understanding of the potential risks, opportunities and challenges linked to climate-altering approaches."

Smith, Wake; Henly, Claire (2021): Updated and outdated reservations about research into stratospheric aerosol injection

Smith, Wake; Henly, Claire (2021): Updated and outdated reservations about research into stratospheric aerosol injection. In Climatic Change 164 (3-4), pp. 1–15. DOI: 10.1007/s10584-021-03017-z.

"In this paper, we seek to ground discussions of the governance of stratospheric aerosol injection research in recent literature about the field including an updated understanding of the technology’s deployment logistics and scale, pattern of effects, and research pathways."

Mace, M.J., et al. (2021): Governing large-scale carbon dioxide removal: are we ready? - an update, Carnegie Climate Governance Initiative (C2G)

Mace, M.J., Fyson, C.L., Schaeffer, M., Hare, W.L. (2021): Governing large-scale carbon dioxide removal: are we ready? - an update, Carnegie Climate Governance Initiative (C2G). February 2021, New York, US.

"This report aims to address these questions, recognising that some degree of reliance on CDR options is now inevitable to achieve the Paris Agreement’s long-term temperature goal, as a direct result of the international community’s delay in making the necessary transition to a low-carbon economy."

Dai, Zhen; et al. (2021): Elicitation of US and Chinese expert judgments show consistent views on solar geoengineering

Dai, Zhen; Burns, Elizabeth T.; Irvine, Peter J.; Tingley, Dustin H.; Xu, Jianhua; Keith, David W. (2021): Elicitation of US and Chinese expert judgments show consistent views on solar geoengineering. In Humanit Soc Sci Commun 8 (1), pp. 1–9. DOI: 10.1057/s41599-020-00694-6.

"We performed face-to-face interviews using formal expert elicitation methods with 13 US and 13 Chinese climate experts randomly selected from IPCC authors or supplemented by snowball sampling. We compare their judgments on climate change, SG research, governance, and deployment."

McLaren, Duncan; Corry, Olaf (2021): Clash of Geofutures and the Remaking of Planetary Order: Faultlines underlying Conflicts over Geoengineering Governance

McLaren, Duncan; Corry, Olaf (2021): Clash of Geofutures and the Remaking of Planetary Order: Faultlines underlying Conflicts over Geoengineering Governance. In Glob Policy. DOI: 10.1111/1758-5899.12863.

"Using evidence gathered from state delegates, climate activists and modellers, we reveal three underlying and clashing ‘geofutures’: an idealised understanding of governable geoengineering that abstracts from technical and political realities; a situated understanding of geoengineering emphasising power hierarchies in world order; and a pragmatist precautionary understanding emerging in spaces of negotiation such as UN Environment Assembly (UNEA)."
