A new report says that CDR technologies will need to be deployed at rates even faster than solar power, to have a chance of limiting global warming to 1.5C.

Q&A: The current state of ‘carbon dioxide removal’ around the world - Carbon Brief
Abatify Summary
Nature & Climate Perspective
**The rapid scaling of Carbon Dioxide Removal (CDR) technologies represents a double-edged sword for global ecosystems, promising long-term atmospheric stabilization while posing acute risks to biodiversity and land-use systems if over-reliant on land-intensive methods. **
- Traditional LULUCF-based removals like afforestation offer immediate ecological co-benefits but suffer from high reversal risks, directly challenging the ICVCM Core Carbon Principles (CCPs) on permanence.
- Novel CDR pathways such as enhanced rock weathering and biochar improve soil health and ocean alkalinity, serving as high-integrity alternatives to traditional land-intensive carbon sinks.
- Large-scale deployment of BECCS (Bioenergy with Carbon Capture and Storage) risks accelerating habitat loss and freshwater depletion, requiring strict ecological safeguards to prevent biodiversity net loss.
Market & Policy Outlook
The integration of engineered CDR into compliance and voluntary markets is driving a systemic shift toward high-permanence assets, reshaping corporate decarbonization strategies under SBTi guidelines.
- The SBTi Net-Zero Standard enforces a strict mitigation hierarchy, mandating that companies use permanent CDR rather than temporary avoidance offsets to neutralize residual Scope 3 emissions.
- Article 6.4 of the Paris Agreement is actively establishing the international accounting framework for integrating CDR credits, allowing them to be traded globally as ITMOs.
- To align with the ICVCM CCPs, voluntary carbon markets are transitioning away from cheap avoidance credits toward highly-vetted, high-cost CDR methodologies to mitigate regulatory and reputational risks.
