Scientists pumped 65,000 litres of sodium hydroxide into the Gulf of Maine. Result: 10 tonnes of CO₂ absorbed, ocean pH restored to preindustrial levels, no harm to marine life detected.

The LOC-NESS project is the first EPA-permitted open-water OAE test. Real data beats theory.

20 years of liming rivers to save Atlantic salmon — now verified as carbon removal. This is what co-benefits look like: habitat restoration paying for itself through CDR credits. RBC buying in shows demand for nature-based removal with real ecological uplift.

Carbon removal + watershed restoration = climate action. 🐟🌊 @NSsalmon's lime dosing program on #NovaScotia's West River has been restoring salmon habitat for 20 years. And now it’s a verified carbon removal solution. 👏 🔗 Learn more: https://t.co/Tgzm6sB4qe

MRV is the bottleneck everywhere — land or ocean. Kiel researchers tackling marine CDR field monitoring confirms what CDI has seen with enhanced weathering: the hardest part isn't removing CO₂, it's proving you did.

"Prove & Learn" before "Speed & Scale."

CDR Must Shift From “Speed & Scale” to “Prove & Learn” — Carbon Drawdown Initiative

For years, the dominant narrative in carbon dioxide removal (CDR) has been speed and scale . Gigatons by 2050. Massive deployment. Rapid expansion. That ambition still matters. But at this stage of industry development, another priority deserves equal attention: proving, learning, and reducing unc

Carbon Drawdown Initiative

The first open-water trial of ocean alkalinity enhancement is underway! 🌊

WHOI's LOC-NESS project is testing how adding alkalinity to seawater can lock away CO₂ — while also fighting ocean acidification.

Ocean-based CDR avoids the land-use conflicts we just saw in the Nature Climate Change study. Rigorous field science before commercial scale = the right approach.

🌊 Woods Hole scientists are testing ocean alkalinity enhancement to fight acidification & store carbon.

The project — LOC-NESS — is running in the Northeast US and aims to keep monitoring and transparency front and center.
