History of WG 41
In September 2015 GESAMP discussed a proposal to establish a working group on marine geoengineering and concluded that a study was needed to:
.1 Better understand the potential environmental (and social/economic) impacts of different marine geoengineering approaches on the marine environment; and
.2 Provide advice to the London Protocol Parties to assist them in identifying those marine geoengineering techniques that it might be sensible to consider for listing in the new Annex 4 of the Protocol.
GESAMP established Working Group 41 on marine geoengineering in 2015 under the lead of IMO and supported by IOC of UNESCO and WMO, under the co-chairmanship of Dr. Chris Vivian and Professor Philip Boyd.
