CCS paper submitted to NEEN26 conference
I have just composed and submitted the abstract below to NEEN26, the NEEN & ISEE Conference on Environmental Ethics which is to be held at Umeå University, Sweden, October 14-16th. The conference is organised by Nordic Environmental Ethics Network (NEEN) in collaboration with International Society for Environmental Ethics (European section) .

The ethical case against Carbon Capture and Storage (CCS)
CCS has become increasingly central as a proposed mitigation measure. The Net Zero goal presupposes Carbon Dioxide Removal (CDR), which may involve the use of so-called negative emission technologies (NETs), which in turn in some cases involve Carbon Capture and Storage (CCS). The Net Zero goal has arguably been misappropriated by fossil fuel interests to promote an agenda that seeks to avoid rapidly phasing out fossil fuels. It is commonly claimed that CCS is a necessity. But CCS as practiced to date has actually been found to be net CO2 additive. While emission reductions from CCS are often uncertain, research confirms that CCS mitigation measures have resulted in mitigation deterrence and climate delay. Regrettably, CCS has not triggered much debate in climate ethics, where anthropocentric perspectives – somewhat surprisingly – predominate. In ethical discussions about CCS, interspecies justice is particularly relevant in two ways: Firstly, in so far as CCS policies contribute to allowing continued greenhouse gas emissions and an overshoot in emissions, this will contribute to exacerbate the impact of climate change, including for non-humans. Secondly, in so far as non-humans are harmfully affected by the transportation of CO2 and long-term dedicated geological storage of CO2 in subsurface environments, this is a direct consequence of CCS policies. Lastly, while future generations is a common concern in environmental ethics, this perspective have not received much attention in the context of CCS. With its required time horizon of at least 10,000 years for underground CO2 storages, CCS is a perfect example of intergenerational externalization of costs in a climate change context. This arguably makes CCS unacceptable from the perspective of intergenerational justice and fairness. In this context, the lack of consensus among researchers on what CO2 leakage rates are acceptable is especially concerning.

The ethical case against Carbon Capture and Storage (CCS)
SHORT ABSTRACT
Based on ethical considerations, this paper argues against the use of Carbon Capture and Storage (CCS) as a climate mitigation measure. CCS has become increasingly central as a proposed mitigation measure. However, despite the widespread claim and perception that CCS is a necessity, CCS as practiced to date has been found to be net CO2 additive, and the Net Zero goal has been misappropriated by fossil fuel interests. Key arguments against CCS are derived from the perspective of interspecies justice, and from the perspective of intergenerational justice and fairness. In the latter context, CCS exemplifies unfair intergenerational externalization of costs.
PROPOSAL
In the global discourse, CCS has become increasingly central as a proposed mitigation measure, particularly after Net Zero targets were added to the global agenda with full force with the Paris agreement. The Net Zero goal presupposes Carbon Dioxide Removal (CDR), which may involve the use of so-called negative emission technologies (NETs), which in turn in some cases involve CCS. The Net Zero goal has arguably been misappropriated by fossil fuel interests and their allies to promote an agenda that seeks to avoid rapidly phasing out fossil fuels. Despite the widespread claim and perception that CCS is a necessity, CCS as practiced to date has been found to be net CO2 additive (Sekera and Lichtenberger 2020). In the big picture emission reductions from CCS are uncertain, whereas research has established that CCS mitigation measures result in mitigation deterrence and climate delay.
Regrettably, CCS has not triggered much debate in climate ethics. On a general note, I find it disappointing that anthropocentric perspectives predominate in climate ethics given that some of the most prominent philosophers engaged with climate ethics, such as Dale Jamieson (2010) and Peter Singer (2009), are well-known for their work in animal ethics. Still, neither of them emphasize interspecies justice in the context of climate ethics (see also Callicott 2011). Interspecies justice is particularly relevant in ethical discussions about CCS in two ways: Firstly, in so far as CCS policies contribute to allowing continued greenhouse gas emissions and an overshoot in emissions, this will contribute to exacerbate the impact of climate change, including for non-humans. Secondly, in so far as non-humans are harmfully affected by the transportation of CO2 and long-term dedicated geological storage of CO2 in subsurface environments, this is a direct consequence of CCS policies. This point is particularly pertinent in light of recent scientific discoveries concerning life dwelling in deep-sea and subsurface environments, which include animal habitats in the subsurface (Bright, Gollner et al. 2024). Lastly, while future generations is a common concern in environmental ethics, this perspective have not received much attention in the context of CCS. With its required time horizon of at least 10,000 years for underground CO2 storages (Lindeberg 2003), CCS is a perfect example of intergenerational externalization of costs in a climate change context. This arguably makes CCS unacceptable from the perspective of intergenerational justice and fairness. In this context, the lacklustre climate effects of CCS to date, the widespread political willingness to rely on unproven technologies, and the lack of consensus among researchers on acceptable CO2 leakage rates, is especially concerning.

#29; 2025 by now most-productive writing year on record
Today I have finished half an article writing day, with some 1.400 words written in the process of composing an abstract prepared in relation to an upcoming special issue of The Journal of Ethics, on the theme "Climate ethics: Prospects and Retrospectives". My paper is titled "The ethical case against Carbon Capture and Storage (CCS)". This was writing day #29 this Autumn (starting July 1st).
Over the last days of this week I have also made a prioritised writing plan for the rest of this Autumn.
By now (or rather by the writing day I had August 8th, when I finished the Captured manuscript) I have written more in 2025 than any previous year on record. In 2021, when I worked on the book Semiotic agency, co-written with Alexei Sharov, among other writing projects, I logged 84.739 words written. By now in 2025 I have already logged 86.459 words written, mostly owing to my work on Captured.

Article on CCS and generational climate justice published
My Norwegian language journal article on Carbon Capture and Storage (CCS) was published this week.

The article is Open Access and thus freely available for full-text reading and download.
English language summary:
Carbon capture and storage (CCS) stands out from other climate mitigation measures by involving storage of CO2 in geological formations for several thousand years. Few if any other mitigation measures raise similar questions related to the long-term impact of the measure. This accentuates the issue of intergenerational justice in relation to CCS. Reliance on CCS represents a moral hazard, since it risks delaying and undermining the needed transition to a fossil-free energy system and society. It would also be fundamentally unjust in that it would burden future generations with much of the practical responsibility for dealing with environmental problems caused by current generations. Emphasis on intergenerational justice should lead us to commit to rapid climate gas emission reductions today rather than relying on negative emissions at some point in the future. Such an assessment is in line with central contemporary climate research as well as key norms in environmental ethics. It is also in line with some of the fundamental insights of deep ecology as developed by Arne Næss.
