Nicolle (2023): A pathway to negative CO2 emissions by 2050: The contribution of the lime industry to a carbon-neutral Europe

Rodolphe Nicolle IN: ce/papers, 6, 2, https://doi.org/10.1002/cepa.2091

This roadmap presents a reference pathway for the European lime sector to achieve negative CO2 emissions by 2050. It is estimated that by 2030, direct CO2 emissions will be achieved through fuel switch to decarbonized/low carbon energy vectors, as well as the first steps in the deployment of carbon capture utilization and storage (CCUS). 


Report: Reducing the Risks of Climate Change

by Climate Overshoot Commission, 14 September 2023

The risk of climate overshoot – that is, of exceeding the Paris Agreement goal of limiting average global warming to 1.5°C – is high and rising, and with it the risk of worsening impacts on human health, food security, water availability, social stability, and ecosystems. People worldwide would welcome a safer, cleaner, more equitable world. All countries could, and should, act now to help bring about such a world. The CARE agenda offers an integrated set of recommendations for achieving this by

  • Cutting emissions of greenhouse gasses
  • Adapting to the unavoidable impacts of climate change
  • Removing carbon from the atmosphere
  • Exploring solar radiation modification


Howard et al. (2023): Blue carbon pathways for climate mitigation: Known, emerging and unlikely

Jennifer Howard, Ariana E. Sutton-Grier, Lindsey S. Smart, Christian C. Lopes, Jill Hamilton, Joan Kleypas, Stefanie Simpson, Jennifer McGowan, Albert Pessarrodona, Heidi K. Alleway, Emily Landis IN: Marine Policy 156, 105788, https://doi.org/10.1016/j.marpol.2023.105788

Here, the authors reaffirm the role of coastal wetlands in climate mitigation opportunities. They update the state of the science regarding existing blue carbon pathways and explore expanding the blue carbon opportunities to new systems. Specifically, the authors analyze new science for those blue carbon pathways they categorize as “emerging” (e.g., management interventions involving macroalgae – both cultivated and wild, tidal flats, and marine sediments) where human action may be able to increase these sinks, but we currently have insufficient information to ensure that their climate mitigation benefit is additional. The authors revisit those that are “non-actionable” (e.g., management interventions involving calcifying organisms and marine fauna) where the scientific evidence is clear that there is no mitigation benefit, or the science is too uncertain to claim that human action can definitively increase these carbon sinks.


Murphy et al. (2023): “Whose carbon is it?” Understanding municipalities role in blue carbon ecosystems management in Canada

Anna E. Murphy, Kate Sherren, Beatrice Frank, Sarah Saunders IN: Nature-Based Solutions 4, 100089, https://doi.org/10.1016/j.nbsj.2023.100089

This study examines the current and potential role of municipalities in the management, protection and/or restoration of blue carbon ecosystems for sustainable land-use planning practices and carbon pollution mitigation by interviewing municipal staff from coastal municipalities across Canada. Study results demonstrated municipal interest in blue carbon ecosystems for their tangible co-benefits, not carbon sequestration and storage capacity, and that restoring blue carbon ecosystems for living shoreline projects was the most common active management strategy at the local level.


Barber et al. (2023): Nature to the rescue: past drivers and future potential of the Australian land-based carbon offsets market

Greg Barber, Andrew Edwards, Kerstin K. Zander IN: Climate Policy, https://doi.org/10.1080/14693062.2023.2239758

As nations consider more ambitious emissions reductions goals, policy makers, carbon market participants and environmental advocates need to estimate the potential scale of nature-based climate solutions (NCS), against the opportunity cost of current land use. In this study, the authors construct a simple linear regression model of the relationship between carbon abatement potential and agricultural profitability, the latter a proxy for opportunity cost, to describe the total set of options for NCS on the Australian continent.


Köhl & Martes (2023): Forests: A passive CO2 sink or an active CO2 pump?

Michael Köhl, Leam M. Martes IN: Forest Policy and Economics 155, 103040, https://doi.org/10.1016/j.forpol.2023.103040

Forests can make a much greater contribution to climate neutrality by harvesting their wood and supplying it to low-emission processing operations, and by sequestering the carbon contained in the biomass used in wood products over the long term.


Project Report: Carbon storage in river and floodplain systems: A review of evidence to update and inform policy development for riverine nature based solutions

David Sear, Imogen Speck, Benjamin Pears, University of Southampton, August 2023

The quantification of carbon stored in floodplains and the potential for restoration to increase this remains poorly understood. To be able to quantify carbon storage it requires understanding how much is buried (storage quantity), over what timescales (storage period) and what processes are associated with carbon burial and storage. These factors are addressed in this report to better understand carbon storage in UK floodplains and whether current restoration is effective at increasing this.


White Paper: Equatic’s Measurement, Reporting, and Verification Methodology

Equatic, August 2023

This white paper presents carbon removal company Equatic’s process for removing carbon dioxide from the atmosphere by means of seawater electrolysis. It describes how CO2 is trapped as aqueous (bi) carbonate ions or within mineral solids, how net carbon dioxide removal (CDR) is rigorously quantified and verified, and why this represents permanent storage. Equatic’s approach is scalable, having demonstrated its ability to mitigate ongoing and accelerating climate change through exacting measurement, reporting, and verification (MRV) protocols and procedures.


Röschel & Neumann (2023): Ocean-based negative emissions technologies: a governance framework review

Lina Röschel, Barbara Neumann IN: Frontiers in Marine Science, 10,  https://doi.org/10.3389/fmars.2023.995130

This article links potential direct and indirect, intentional and unintentional impacts of eight ocean-based negative emissions technologies (ONETs) on the marine environment to the regulations and policy goals of international environmental agreements of the current global ocean governance regime. The results thereof outline a direct, implicit and indirect governance framework of ONETs. Hereby, a broader perspective of the concept of (global) ocean governance is adopted to outline a wider network that goes beyond the explicit regulation of ONETs within the realm of ocean governance. This first-order assessment derives gaps and challenges in the existing governance framework, as well as needs and opportunities for comprehensive governance of the technologies.


Briefing paper: WWF priorities for the EU Carbon Removal Certification Framework

on wwf.eu, 27 July 2023

„Increasing Carbon Dioxide Removal from the atmosphere is an essential part of the global fight to limit temperature rise to 1.5C and stop runaway climate change. In this context the European Commission’s proposal for a Carbon Removal Certification Framework (CRCF) could potentially be a useful instrument and set a good example internationally. Unfortunately, the current proposal falls short. It fails to define important concepts, leaving most of the details to be established by the Commission later through delegated acts. It also fails to specify how these certificates might be used, nor does it establish robust safeguards to avoid undermining climate action and harmful impacts on nature and avoid potential greenwashing. In this paper, the authors highlight the top priorities that the Parliament and Council should address in order to make the CRCF fit for purpose.“
