The 2nd International Conference on Negative CO₂ Emissions was held at Chalmers University of Technology, Gothenburg, Sweden, June 14-17, 2022. These are Bellona’s main takeaways from the conference.

In this study, the authors utilize an expert interview exercise (N = 125) to examine the whole systems justice issues associated with ten negative emissions and ten solar geoengineering technologies. They ask: What equity and justice concerns arise with these 20 options? What particular vulnerable groups could be affected? What risks do these options entail for communities or the climate?

This consultation is seeking views on the design of a business model to attract private investment and enable GGR projects to deploy at scale from the mid-to-late 2020s. The consultation is open to all organisations and individuals, but will be of particular interest to those with an interest in GGR technologies and negative emissions markets. This consultation closes at 11:45pm on 27 September 2022.

In Part I of this work, the authors reviewed the current state of geochemical NETs, highlighting key features (mineral resources; processes; kinetics; storage durability; synergies with other NETs such as DAC, risks; limitations; co-benefits, environmental impacts and life-cycle assessment). The role of organisms and biological mechanisms in enhancing geochemical NETs is also explored. In Part II, a roadmap is presented to help catalyze the research, development, and deployment of geochemical NETs at the gigaton scale over the coming decades.

What exactly negative emissions are, how they can be generated by nature-based and technological processes, and the advantages and disadvantages of different methods are explained in the new edition of our „In a Nutshell!“ format.

Here the authors identify three risks associated with using carbon markets as the sole, or main, policy lever to encourage the deployment of GGR (Greenhouse Gas Removal) techniques. The categorisation of risks stems from discussions with policymakers in the UK and a review of the broader literature on carbon markets and GGR.

The authors investigate seven different pathways for producing aviation biofuels coupled with either bio-energy carbon capture and storage (BECCS), or bio-energy carbon capture and utilization (BECCU). Both options allow for increased efficiency regarding utilization of feedstock carbon. The analysis uses process-level carbon- and energy balances, with carbon efficiency, climate impact and LCOP as primary performance indicators.

This book discusses the importance of transitioning from conventionally fuelled, electric and hydrogen personal vehicles towards low carbon electric and hydrogen public transport. It presents international comparisons and case studies of countries who have successfully and unsuccessfully implemented policies to reduce their emissions from land-based transport.

„Radical emissions cuts combined with some atmospheric carbon removal are the only hope to limit global warming to 1.5 °C, scientists warn.“ Some key points of the recent IPCC reports are mentioned and statements of e.g. Inger Andersen, executive director of the UN Environment Programme, as well as of Oliver Geden, a social scientist with the German Institute for International and Security Affairs in Berlin, a lead author on the report, are given.
