Enhanced rock weathering may offer durable, cost-competitive carbon removal with potential added benefits like increased crop yields. However, uncertainty persists in ERW projects, with key risks related to over crediting and the potential for causing environmental and social harms. This means that, to maximize benefits and reduce risks, this carbon removal pathway requires more research and investment. 

A new report by Carbon Direct analyzes the current risks and benefits of enhanced rock weathering and assesses it against high-quality criteria to help buyers make more informed purchases.
