Emerging carbon removal technologies like enhanced weathering and ocean alkalinity enhancement are moving from concept to field deployment.
Recent scientific assessments suggest current carbon removal estimates may be overly optimistic due to complex Earth-system feedbacks.
Captured carbon can be lost as it moves through soils and rivers, often becoming trapped in new minerals before reaching the ocean.
Long-term durability and the issue of 'additionality' remain critical hurdles for the credibility of global carbon credit markets.
