- Various methods of carbon dioxide removal (CDR) are being pursued in response to the climate crisis, but they are mostly not proven at scale. Climate experts are divided over whether CDR is a necessary requirement or a dangerous distraction from limiting emissions. In this Viewpoint, six experts offer their views on the CDR debate.

Why residual emissions matter right now

- Net-zero targets imply that continuing residual emissions will be balanced by carbon dioxide removal. However, residual emissions are typically not well defined, conceptually or quantitatively. We analysed governments’ long-term strategies submitted to the UNFCCC to explore projections of residual emissions, including amounts and sectors. We found substantial levels of residual emissions at net-zero greenhouse gas emissions, on average 18% of current emissions for Annex I countries. The majority of strategies were imprecise about which sectors residual emissions would originate from, and few offered specific projections of how residual emissions could be balanced by carbon removal. Our findings indicate the need for a consistent definition of residual emissions, as well as processes that standardize and compare expectations about residual emissions across countries. This is necessary for two reasons: to avoid projections of excessive residuals and correspondent unsustainable or unfeasible carbon-removal levels and to send clearer signals about the temporality of fossil fuel use.

Has It Come to This? : The Promises and Perils of Geoengineering On the Brink
- 2020
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Geoengineering is the deliberate and large-scale intervention in the Earth's climate system in an attempt to mitigate the adverse effects of global warming. Now that climate emergency is upon us, claims that geoengineering is inevitable are rapidly proliferating. How did we get into this situation where the most extreme path now seems a plausible development? Is it an accurate representation of where we are at? Who is this “we” who is talking? What options make it onto the table? Which are left out? Whom does geoengineering serve? Why is the ensemble of projects that goes by that name so salient, even though the community of researchers and advocates is remarkably small? These are some of the questions that the thinkers contributing to this volume are exploring from perspectives ranging from sociology and geography to ethics and indigenous studies. We set out this diverse collection of voices not as a monolithic, unified take on geoengineering, but as a place where creative thinkers, students, and interested environmental and social justice advocates can explore nuanced ideas in more than 240 characters.

Net zero and the unexplored politics of residual emissions
- 2023
-
Ingår i: Energy Research & Social Science. - : Elsevier BV. - 2214-6326 .- 2214-6296. ; 98:April

Tidskriftsartikel (refereegranskat)abstract
- In this perspective article, we call for more engagement with the unexplored politics of residual emissions. Residual emissions are those emissions that remain at the point of net zero, despite abatement efforts. Unlike carbon dioxide removal, which has been the focus of a lively research and policy debate, the notion of residual emissions remains relatively unexplored so far. With the mainstreaming of net zero as the long-term goal of climate policy, the politics of residual emissions are set to become a key point of contestation. Claims about residual emissions tend to revolve around notions of necessity and possibility, i.e. emissions that derive from activities deemed socially necessary yet impossible to fully abate. In this perspective article, we highlight how such claims are socially constructed and ultimately contingent on values, norms and interests. We call upon researchers to help render visible the geographically and historically contingent claims to necessity and possibility that underpin projected residual emissions. We see this as an important means to repoliticize debates about the limits and possibilities of emissions abatement, and suggest entry points for such research efforts.

UNFCCC must confront the political economy of net-negative emissions
- 2021
-
Ingår i: One Earth. - Cambridge, MA, United States : Cell Press. - 2590-3330 .- 2590-3322. ; 4:10, s. 1348-1351
-
Tidskriftsartikel (refereegranskat)abstract
- Recent demands by developing countries, like India, that developed countries need to reach net-negative emissions, must be negotiated seriously under the UNFCCC. Failure to acknowledge that limiting global average temperature rise to 1.5°C leaves very little carbon budget for equitable redistribution risks further ambiguity on how to achieve the Paris Agreement’s goals.
