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.

Start-up asked for regulation changes to allow controversial marine carbon storage

Gigablue applied for permission to put a thousand tonnes of its particles in New Zealand waters - but was told its plans amounted to marine dumping.

Alternate (but still quite accurate) summary from a contact elsewhere:

"James Shaw lobbying for Israeli geoengineering startup to remove regulation so they can scale up unproven technology in the ocean without peer review in order to sell carbon credits to the corporate greenwashing market."

Make of that what you will. 🤷

@pezmico that sounds horrific.
@Niall @pezmico my goodness!! What's he thinking.
