Are Carbon Offsets Fixable?
by Benjamin Sovacool 10 Oct '25

10 Oct '25

Hi all, a few of us were discussing this recent paper at the UPTAKE meeting, some sober findings about offsets for things like nature based solutions but also our ongoing discussions about durability and permanence of storage. Link below, but PDF attached for convenience. ** https://www.annualreviews.org/content/journals/10.1146/annurev-environ-1128… ABSTRACT This article provides a systematic review of the literature on carbon offsets. A growing number of studies have found that the most widely used offset programs continue to greatly overestimate their probable climate impact often by a factor of five to ten or more. Credit quality has remained a problem since the inception of carbon credits, despite repeated efforts to address the core challenges of additionality, leakage, double counting, environmental injustice, verification, and permanence. Combined, these issues have led many to conclude that overcrediting in carbon offsets is an intractable problem. These challenges helped stall the rapid growth in the voluntary carbon market (VCM) earlier this decade. They warrant renewed focus in the wake of COP29, where 200 nations significantly advanced the effort begun with the Paris Agreement to create the rules governing a global compliance market for carbon credits. But COP29 did not substantially address the quality problem, creating the risk the Paris compliance market will be rife with overcrediting and other problems-and that the VCM could undermine the Paris market. We recommend that all stakeholders begin focusing on high-integrity, durable carbon dioxide removal and storage, while recognizing that the recent literature has raised the question of whether durable means 100 years, 1,000 years, or longer. Ultimately, we find that many of the most popular offset project types feature intractable quality problems. We should focus on creating rules to find and fund the relatively few types of high-quality projects while employing alternative finance and strategies such as contribution claims for the critical projects in conservation, renewable energy, and sustainable development.

Where: G9 Meeting Room Dear GENIE team, We are pleased to announce that Candelaria Bergero (YSSP 2024) will be joining us online to present her work on the climate implications of failing to manage carbon. Please mark your calendars and join us for an exciting input and fruitful discussion. Title: The climate implications of failing to manage carbon Abstract: In scenarios that limit the increase in global mean temperature (GMT) this century to 1.5 or 2°C, large quantities of carbon are managed by both carbon capture and storage (CCS) at point sources and atmospheric carbon dioxide removal (CDR). Such carbon management may be used to offset ongoing (“residual”) emissions from hard-to-abate sectors and to decrease the concentration of carbon dioxide in the atmosphere if various feasibility and sustainability challenges are overcome. Here, in over 16 million simulations of the simple climate model MAGICC, we systematically analyze the climate implications of failing to manage carbon to the degree called for in 407 different climate mitigation scenarios. We find that entirely failing to manage carbon relates to ~0.5°C higher GMT in 2100, making it impossible to meet the 1.5°C target, but leaving 2°C in reach this century–assuming the projected decreases in emissions still occur. Our results also show that peak temperatures are especially sensitive to land-based CDR (afforestation and reforestation) that often ramps up quickly in the scenarios, whereas end-of-century temperatures depend more on levels of engineered CDR (bioenergy with carbon capture and storage, direct air capture with storage). What is clear, though, is that the quantity of carbon in avoided emissions is vastly larger than carbon managed in every climate mitigation scenario.

FW: Antarctica - Government opposed to polar geoengineering
by Benjamin Sovacool 11 Sep '25

11 Sep '25

Fascinating, the UK debate continues to evolve … (and Jan and the PIK team, this does subtly signify the value to looking at European parliamentary debates to see what narratives and themes are being deployed, in my opinion, which we had proposed for WP6 😊) From: Environmental Audit Committee <EACOM(a)parliament.uk> Sent: Thursday, September 11, 2025 7:51 AM To: Environmental Audit Committee <EACOM(a)parliament.uk> Subject: Antarctica - Government opposed to polar geoengineering House of Commons Environmental Audit Committee Thursday 11 September 2025 Antarctica: Government opposed to polar geoengineering · UK also “keen to further engage” China on environmental protection in Antarctica Government response: The UK and the Antarctic environment <https://url.uk.m.mimecastprotect.com/s/WRGXC9gLlTk9W4VvuofEtqeJDb?domain=pu…> The Environmental Audit Committee has published the Government’s response to the Committee’s report on ‘the UK and the Antarctic environment’. In its response, the Government rejects the use of Solar Radiation Management, or ‘geoengineering’, saying the UK has no plans to deploy the technique. This week a group of 42 polar scientists published analysis which found that proposed geoengineering techniques were not feasible and could even be “environmentally dangerous”. The Government accepts many of the Committee’s other recommendations, including pressing Russia to reaffirm its commitment to the prohibition of mining and prospecting in Antarctic waters and fostering dialogue with all Antarctic Treaty System members, including China, on environmental protection and scientific cooperation. It also agrees with the Committee’s recommendation that the Government should intensify diplomatic engagement to address the concerns of China and Russia in discussions around fishing quotas and Marine Protected Areas. “The UK Government is keen to further engage China on the krill management framework and advance discussions on Marine Protected Areas and continues to seek opportunities to advance these discussions,” it says. ENDS Further information The Environmental Audit Committee considers the extent to which the policies and programmes of government departments and non-departmental public bodies contribute to environmental protection and sustainable development, and to audit their performance against sustainable development and environmental protection targets. It is not a government committee but a select committee of the House of Commons with a key role in holding ministers to account. Any of our inquiries would correctly be described as a ‘parliamentary inquiry’ and not a ‘government inquiry’.

Upcoming GENIE meeting at IIASA
by BRUTSCHIN Elina 31 Aug '25

31 Aug '25

Dear all, We at IIASA are already very excited to see you soon and to kick off the new school year together! We wanted to inform you that the meeting location has changed. The meeting will now be held at Webster Vienna Private University, Praterstraße 24, 1020 Vienna. This is a very central location, and given the collaborative, writing-focused style of the meeting, we thought a classroom setting with whiteboards, projectors, and breakout spaces would be ideal. Since this meeting will be work-intensive, kindly ensure you bring your laptop and charger. We will provide continuous coffee/tea and snacks (thus no clear coffee breaks) and teams take breaks as needed, and if you need to take a meeting, there will also be space available for focused work. There are plenty of nice hotels and Airbnb options nearby if you would like to adjust your accommodation. Otherwise, the venue is easily accessible from Hauptbahnhof (U1 line). Regarding social activities, we plan to focus on urban CDR and then also some communication training for policy briefs — more details will follow soon. We also suggest bringing yoga pants and/or running gear for some informal exercise sessions (more infos also to follow). While the agenda is still subject to minor changes, we wanted to share the more detailed preliminary plan with you (and what you could prepare before the meeting). As discussed during our GENIE meetings, the idea is to hold a writing-focused meeting (but can also be data analysis etc.). We will start with a brief plenary session where paper leads can pitch their paper idea, followed by dedicated time to work on the papers in smaller groups. The papers can be at different stages of development, and the goals of each group may vary. For example, if a paper is already at an advanced stage, the group lead might assign others to review specific sections. If it's still in an early phase, the team may choose to reframe the research question based on initial feedback from the full consortium etc. We have designed the meeting format to be interactive and flexible, with a balance between focused group work and opportunities for broader feedback from all participants. We will also make sure that related paper groups are spatially close to each other so that there is an opportunity to discuss some things across groups. At the top of the agenda<https://docs.google.com/document/d/1WFWbamSuP_BDH_7qEufpQRg8aLwSsmCF/edit?u…>, I have included a preliminary group allocation based on the preferences that all of you submitted earlier. Please review this and feel free to make adjustments — team members can also switch groups on site. There's no obligation to stick to the proposed groups, and this setup does not affect authorship in any way, as many of you will be co-authors across multiple papers. Next Steps: If the paper leads are happy with the proposed structure, it would be great if you could prepare a 5-minute pitch for your paper to present at the beginning of the meeting. These pitches should briefly cover: * The research question * Expected outcomes of the paper * What you would like to accomplish during the meeting (where do you need support from others at this stage) I have created a <https://drive.google.com/drive/folders/1c7DmiuyljCykXfxPDjGy4fDxHEO_4Wwp?us…> Google Drive folder<https://drive.google.com/drive/folders/1c7DmiuyljCykXfxPDjGy4fDxHEO_4Wwp?us…> where you can upload your pitch presentations, any drafts, and relevant literature you would like others to review ahead of or during the meeting. We have also scheduled the usual round of updates from all teams at the beginning of the meeting. Please keep these brief and focus on recent publications and upcoming papers that might be of interest to others. In addition, we have set aside some time to reflect on the remaining deliverables — this is simply to ensure that the papers we are proposing are aligned with what is still needed. Please feel free to comment on the agenda and also let me know in case I forgot to include someone! Best regards, Elina on behalf of IIASA team

by BRUTSCHIN Elina 11 Jun '25

11 Jun '25

Dear GENIE colleagues, I hope that everyone is well. For our next GENIE meeting at IIASA in September, we thought it would be valuable to focus on collaboratively developing papers and policy briefs. To make the most of our time together, it would be helpful to decide in advance which lines of work and specific papers we would like to prioritize. We at IIASA have started brainstorming some ideas and would like to share and discuss them with you on Monday. Please feel free to suggest any additional ideas from your side as well, so we can discuss this a bit more in detail on Monday in the following document<https://docs.google.com/document/d/1WFWbamSuP_BDH_7qEufpQRg8aLwSsmCF/edit?u…>, which also already contains some preliminary proposed structure of our meeting. Best regards, Elina
