Researchers look at marine environment’s huge potential for carbon sequestration

Scientists are aiming to unlock the local secrets of blue carbon, with research underway to deliver Aotearoa’s first national estimate of natural kelp-carbon sequestration in the marine environment.

With our native giant kelp sequestering about 52 tonnes of carbon dioxide per hectare every year - more than double the amount of pine trees - blue carbon has huge potential for climate mitigation.
