Colour me sceptical.
mCDR (Marine Carbon Dioxide Removal) is an umbrella term which encompasses things from looking after mangroves and seagrasses (good stuff) to borderline geoengineering and dumping a variety of materials into the ocean (questionable and even probably bad stuff).
So far it has been mostly proven to be an efficient mechanism for dodgy start-ups to sell carbon credits and do greenwashing.
Beware the Snake Oil salespeople.
