Zeng & Hausmann (2022): Wood Vault: remove atmospheric CO2 with trees, store wood for carbon sequestration for now and as biomass, bioenergy and carbon reserve for the future

Ning Zeng, Henry Hausmann IN: Carbon Balance Manage 17, 2 (2022),

Wood harvesting and storage (WHS) is a hybrid Nature-Engineering combination method to combat climate change by harvesting wood sustainably and storing it semi-permanently for carbon sequestration. To date, the technology has only been purposefully tested in small-scale demonstration projects. This study aims to develop a concrete way to carry out WHS at large-scale.


Coupled Model Simulations of Carbon Dioxide Removal via Ocean Alkalinity Enhancement and Large-scale Afforestation and Reforestation

Hao-wei Wey, Tronje Kemena, David Keller, Andreas Oschlies IN: EGU General Assembly 2022, Vienna, Austria, 23–27 May 2022, EGU22-7662,, 2022.

…to be discussed at the EGU conference (Vienna, Austria & Online, 23–27 May 2022). „As part of the CDR Model Intercomparison Project (CDRMIP), we utilize here the land-ocean-atmosphere coupled FOCI-MOPS model to study the potential reversibility and impacts of different proposed CDR methods. FOCI-MOP is an integration of the marine biogeochemical model, Model of Oceanic Pelagic Stoichiometry (MOPS), in the Flexible Ocean and Climate Infrastructure (FOCI) ESM. Two CDR methods are studied under highly-idealized scenarios: a marine-based CDR of ocean alkalinity enhancement, and a land-based CDR of afforestation and reforestation, given their large theoretical mitigation potentials.“


Report: Technology Readiness Assessment, Costs and Limitations of five shortlisted NETs

Kenneth Möllersten, Raza Naqvi, Mälardalen University, Report of the NET-RAPIDO Project: Negative emission technologies: readiness assessment, policy instrument design, options for governance and dialogue, 77 pp.

This report presents an in-depth technology readiness, cost assessment and an analysis of practical deployment barriers for NETs along with an analysis of related knowledge gaps and research needs. The selected NETs are (i) bioenergy with carbon capture and storage (BECCS); (ii) direct air capture and storage (DACCS); (iii) large-scale afforestation and reforestation; (iv) soil carbon sequestration; (v) Biochar as soil additive; (vi) Enhanced Weathering; (vii) Accelerated Mineralization; (viii) Ocean fertilization.


Waller & Chilvers (2022): Climate Change Assessments, Publics and Digital Traces of Controversy: An Experiment in Mapping Issues with Carbon Dioxide Removal Researchers

Laurie Waller, Jason Chilvers IN: Science & Technology Studies. doi: 10.23987/sts.107662

This paper reports a participation experiment in which the authors involved an interdisciplinary group of researchers in mapping issues relating to two CDR approaches: afforestation and bioenergy with carbon capture and storage (BECCS). The authors discuss the prospects for bringing experimental approaches to mapping issues, publics and participation into closer relation with science and technology assessments.


Cooper et al. (2022): Life cycle assessment of negative emission technologies for effectiveness in carbon sequestrations

Jasmin Cooper, Luke Dubey, Adam Hawkes IN: Procedia CIRP, Volume 105, 2022, pp. 357-361,

The authors conducted a life cycle assessment (LCA) to compare four NETs: afforestation/reforestation, enhanced weathering, direct air capture and bioenergy with carbon capture and storage. These are compared on their life cycle impacts to climate change, land use change and toxicity (human and terrestrial).


Nature – Koch & Kaplan (2022): Tropical forest restoration under future climate change

Alexander Koch and Jed O. Kaplan IN: Nature Climate Change (2022).

To investigate the risks to tropical forest restoration, the authors performed 221 simulations with a dynamic global vegetation model (LPJ-LMfire) driven by a range of future climate scenarios and ecophysiological responses to CO2 concentrations. They show that carbon in restored tropical forests is largely preserved under the entire range of potential future climates, regardless of assumptions they make about the potential for CO2 fertilization of photosynthesis.


Chu et al. (2022): A global analysis of the break-even prices to reduce atmospheric carbon dioxide via forest plantation and avoided deforestation

Long Chu, R. Quentin Grafton, Hai Nguyen IN: Forest Policy and Economics, Vol 135, 2022, 102666,

The authors provide a global and bottom-up assessment of the break-even carbon price to undertake forest plantation and forest conservation at a country level for 166 nations. A global dataset of key cost factors was created, their global distributions was examined, and a cross-country assessment of cost differences was conducted with alternative forest programs (plantation and conservation).


New OECD Environment Working Paper: A global analysis of the cost-efficiency of forest carbon sequestration

R. Quentin Grafton, Hoang Long Chu, Harry Nelson, Gérard Bonnis; No. 185, 66 pp.;

This paper proposes a ranking of the 166 countries where forest carbon sequestration is the most cost-efficient. Taking into account the main cost factors leads to a more nuanced ranking than assuming that the most cost-effective projects would be in tropical areas with high rainfall. The ranking reflects differences in opportunity cost of land use and labour cost, the quality of the business environment, natural conditions such as wildfire risk and the level of avoided GHG emissions from alternative land use. Its results support the view that forests can be a cost-efficient way to offset GHG emissions and that significant cost reductions are possible by targeting country and sub-national regions.


Science – Poorter et al. (2021): Multidimensional tropical forest recovery

Lourens Poorter, Dylan Crave, Catarina C. Jakovac, Masha T. van der Sande, Lucy Amissah, Frans Bongers, Robin L. Chazdon, Caroline E. Farrior, Stephan Kambach, […] Bruno Hérault, + 81 authors IN: Science, Vol 374, Issue 6573, 1370-1376, DOI: 10.1126/science.abh3629

Although deforestation is rampant across the tropics, forest has a strong capacity to regrow on abandoned lands. These “secondary” forests may increasingly play important roles in biodiversity conservation, climate change mitigation, and landscape restoration. Poorter et al. analyzed the patterns of recovery in forest attributes (related to soil, plant functioning, structure, and diversity) in 77 secondary forest sites in the Americas and West Africa.
