„Bäume binden CO2 – Aufforstung ist also gut fürs Klima? So einfach ist es nicht, wie eine neue Studie nun belegt. In einigen Gebieten könnte es demnach sogar kontraproduktiv sein, viele Bäume zu pflanzen.“
Here is a subjective list of key players and experts in the global Direct Air Capture ecosystem, compiled by Julius Wesche (PhD); Climate Innovation Researcher at the Norwegian University of Science and Technology, Trondheim, Norway. The list will be continuously updated, based on suggestions and comments.
The Yale Center for Natural Carbon Capture (https://naturalcarboncapture.yale.edu/) at Yale University is accepting applications for up to three Postdoctoral Associates. Applicants are welcome with research interests across the full range of disciplines related to the Center’s three focal areas: Ecological and Biological Carbon Capture; Geological and Ocean Carbon Capture, and Industrial Carbon Utilization.

Here, the authors present estimates for the response of CO2 emissions from tropical peat soils, rivers and coastal waters to changing soil acidity induced by enhanced weathering application. They estimate that the potential carbon uptake associated with enhanced weathering is reduced by 18–60% by land-based re-emission of CO2 and is potentially offset completely by emissions from coastal waters.

In this report, the Institute for Global Sustainability synthesizes scientific literature, industry reports, government policies, and news to assess the potential for DACCS as a compliance pathway in local emissions reduction ordinances and other regulations, for example by the City of Boston through the Building Emissions Reduction and Disclosure Ordinance 2.0 (BERDO 2.0).

The Carbon Business Council, a trade association of more than 65 carbon management companies, has published this white paper on the intersection of voluntary carbon markets (VCMs) and carbon dioxide removal (CDR). The paper features recommendations for market regulators and existing market providers about how to grow VCMs, scale carbon removal, and provide a more diverse portfolio of climate solutions for purchasers. VCMs are projected to grow to a $50 billion market by 2030.

This work discusses a hybrid method that combines primary production via the growth of autotrophic microorganisms (i.e., photosynthetic cyanobacteria) and microbially-induced carbonate precipitation. Carbon fixation and carbonate precipitation can be co-optimized by using bipolar membrane electrodialysis devices (BPMEDs), which generate seawater with adjustable pH. The authors examine the scale-up potential for naturally produced bio-carbonate composite materials and compare its production with published ocean CDR strategies for reducing anthropogenic CO2 emissions.

This article first describes the challenges and uncertainties the authors face as an early buyer in quantifying carbon removal deliveries in a nascent field. The authors then suggest a framework to make it actionable for buyers–including Frontier itself. The hope is that this helps buyers more confidently make purchasing decisions from a range of carbon removal pathways–particularly from promising early solutions that are harder to quantify.
The new version of Puro Standard Biochar carbon removal methodology – edition 2022 – is ready to be used. During last 2.5 years, the Puro project members have been fortunate to gather feedback and learn from our global biochar producers, scientific experts, pioneering CORC buyers as well as auditors in Europe, Australia and the Americas. All of these learnings are now captured in the updated methodology.
