White Paper – Sustainably Amplifying the Natural Carbon Cycle 

by Jordan Breighner, Max Chalfin, Rishi Masalia, Marty Odlin, Jessica Makolin, Justin Ries, Luke Rondel on Running Tide, March 8, 2023

Running Tide is developing a nature-based carbon dioxide removal (CDR) system that sustainably amplifies the biological pump’s transfer of carbon from the fast to the slow carbon cycle. This white paper provides an overview of the Earth’s carbon cycle, the ocean’s natural processes for capturing and storing carbon, and how Running Tide’s system is designed to sustainably enhance these processes. Running Tide’s CDR system combines distributed open ocean aquaculture, the sinking of biomass, and ocean alkalinity enhancement to make a significant contribution to the fight against the global climate crisis, while delivering co-benefits for biodiversity, sustainable development, inclusive economic growth, and food security.


Report: Ocean-based carbon dioxide removal landscape in China

Weijie Wang, Junjie Zhang, Climateworks Foundation, 6 March 2023

This report synthesize the current state of scientific knowledge on ocean CDR approaches in China through literature review and stakeholder interviews. The researchers identified and examined four ocean CDR approaches proposed and practiced in China — seaweed cultivation, artificial upwelling, microbial carbon pump, and offshore carbon storage. In addition, the report discusses the potential and challenges of these approaches and provides recommendations where further research is needed.


Certification of Carbon Dioxide Removals-Evaluation of the Commission Proposal

Dr. Nils Meyer-Ohlendorf, Anne Siemons, Dr. Lambert Schneider, Dr. Hannes Böttcher; German Environment Agency; March 2023, 35 pp.

This report assesses the Commission’s proposal for the CRCF and discusses interlinkages of the CRCF with other pieces of EU climate law. The report provides an overview of the proposal’s main elements and assesses them. Criteria for assessment include (1) whether the proposal strengthens EU climate policies, (2) whether it safeguards the integrity of climate policies, (3) whether it contributes to strong environmental policies and (4) whether it takes account of other aspects relevant for the uptake of carbon removals, such as energy consumption, cost saving, and innovations


Report: Greenhouse gas removal in Australia: A report on the novel negative emissions approaches for Australia roundtable

The Australian Academy of Science convened a roundtable of experts in 2022 to discuss the scientific capability, research and collaboration needed to support new breakthroughs in greenhouse gas removal. This report provides a summary of the roundtable discussions and presentations, and provides some guidance on opportunities and actions.


Report: Biochar in forestry. Status in the Nordic-Baltic countries

Hanssen, Kjersti Holt; Bruckman, Viktor J.; Gundale, Michael; Indriksons, Aigars; Ingerslev, Morten; Kaivapalu, Marju; Lazdina, Dagnija; Makovskis, Kristaps; O’Toole, Adam; Ots, Katri; Palviainen, Marjo; Stokland, Jogeir Nicolai; Varnagiryte-Kabasinskiene, Iveta (2023); NIBIO https://hdl.handle.net/11250/3054879

The report gives an overview of current and potential uses, production methods and facilities, legislation, current and future research as well as biochar properties and effects. So far, most biochar studies have been conducted on agricultural soils, though research in the forestry sector is starting to emerge. The first biochar field experiments in boreal forests support that wood biochar promotes tree growth. Also, studies on the use of biochar as an additive to the growing medium in tree nurseries show promising results.


Report: Development of Novel Materials for Direct Air Capture of CO2: MIL-101 (Cr)-Amine Sorbents Evaluation Under Realistic Direct Air Capture Conditions 

Christopher W Jones, Ryan P Lively, Matthew J Realff; Final Report, United States, 2023; doi:10.2172/1907464

The overarching goal of this project is to evaluate the CO2 adsorption properties of a small family of metal-organic framework (MOFs) materials functionalized with amines at sub-ambient conditions. The authors use the sub-ambient lab instrumentation designed or adapted to study the behavior of the pristine metal organic framework (MOF) MIL-101(Cr) and the MOF in the presence of amines ranging from small molecules (e.g. TREN, tris(2-aminoethylamine)) to oligomers (e.g. PEI, poly(ethyleneimine)).


Report: The Ocean Carbon Dioxide Removal Decision-Making Landscape

Sarah R. Cooley, George H. Leonard, Anna Zivian, Eleanor D. Pierel, on Ocean Conservancy.org, 28 pp.

Ocean carbon dioxide removal (OCDR) research is advancing rapidly as part of a global hunt for effective climate mitigation actions. This report examines 12 interest groups in the U.S. OCDR community, spanning from specialists like academic researchers to general information users in civil society. The authors evaluated public-facing products from each interest group, then conducted semi-structured interviews and informal conversations with interest group members to learn about their interests, activities and concerns. Following the analysis of each interest group, we synthesize the most prominent themes.


Enhanced Rock Weathering in the Global South: Exploring Potential for Enhanced Agricultural Productivity and Carbon dioxide Drawdown

F. Garrett Boudinot, Gabrielle Dreyfus, Caitlan Frederick, Yifan Powers (Precision Development (PxD) and the Institute for Governance & Sustainable Development (IGSD)); January 2023; 42 pp.

The authors aim to identify opportunities in agriculture with potential benefits for smallholder farmers, either directly or through compensation mechanisms for their environmental services, as well as for GHG mitigation. In identifying these opportunities, the authors will outline the evidence for impact on farmers‘ outcomes and on GHG-mitigation outcomes as well as address challenges in building that evidence, particularly in outcome measurement methods. They will also address practical next steps to build a pathway to scale for the identified opportunities.


White Paper: Ocean-Based Carbon Dioxide Removal Practices

Release date: February 7, 2023; Foundation for Climate Restauration

This is the fifth installment of the Foundation’s Solution Series, which examines a diverse portfolio of natural and technological approaches that can remove CO2 from the atmosphere and return us to safe, preindustrial levels of carbon. In this paper, the authors explore Ocean-Based Carbon Dioxide Removal through a climate restoration lens. They discuss Ocean-Based CDR’s capacity to achieve scalable, financeable, durable, and equitable outcomes and then provide ways for readers to advocate for its safe and thoughtful implementation.
