A survey of international environmental experts suggests that attitudes to the decommissioning of offshore infrastructure have shifted.

Almost 95 percent of the experts, drawn from 10 nations and across academia, government and industry, believe that a more flexible, case-by-case, approach to equipment removal would be better for the environment.

Obsolete offshore infrastructure, including oil and gas platforms and wind turbines, must be removed in most regions of the world once they reach the end of their productive lives. Yet the practice has potential large-scale environmental impacts, including the loss of biodiversity and destruction of sea-bed habitat. More than 7,500 offshore oil and gas platforms in 53 countries will become obsolete in the next few decades, with eventual removal of rapidly growing wind turbine infrastructure a looming issue.
