Marine CO₂ removal lacks standardized indicators to quantify carbon removed and environmental impacts. This absence of reliable metrics prevents verification, inhibits investment, and blocks entry into carbon trading systems.

One of my staff asked an interesting question today; to what extent companies can #patent the ideas behind 'negative emission technologies'. Their reason for asking was a company filing a patent that covers many aspects of the use of ocean alkalinity enhancement for sequestering CO2.

Like all other CO₂ removal (CDR) techniques, significantly more research is needed over the next few decades to determine whether enhanced rock weathering is a viable method for CDR.
Challenges and opportunities in scaling enhanced weathering for carbon dioxide removal - Nature Reviews Earth & Environment
Commercial investment in enhanced rock weathering for carbon dioxide removal on agricultural lands is growing rapidly. This Review explores the potential of large-scale deployment, outlining the challenges faced in science, policy and governance to scale the technology.

We finally have a new paper out looking at how summary statistics from the AR6 scenario database are highly dependent on the sampling of the database.
High profile statistics are often more representative of the model fingerprint, not the physics.
