Dr Lyndsey Dodds is the head of marine at the World Wildlife Foundation environmental charity.
She believes North Sea platforms should be decommissioned.
Dr Dodds said: “Having made hundreds of millions of pounds in profit over the years, oil and gas companies should not be allowed to dodge their obligations to clean up their mess and protect the marine environment.
“The agreement under OSPAR (the mechanism by which Governments co-operate to protect sea life) already allows, in certain circumstances such as protecting worker safety or preventing serious risk to the environment, for companies to request permission to leave some stuff behind on the seabed.
“This is something we support.
“It should be remembered that it’s only because of these OSPAR rules that every rig placed in the North Sea for the past two decades has had to be built in a way that allows it to be removed.
“Any moves to unwind OSPAR’s rules on this issue would not be in the interests of protecting the marine environment or maintaining the ‘polluter pays’ principle.
“The possibility of some future funding for environmental projects is not a reason for the oil and gas sector to leave behind potentially polluting infrastructure in the North Sea.”
