Greenhouse Gas Emissions from Decommissioning Manmade Structures in the Marine Environment; Current Trends and Implications for the Future

The decommissioning of manmade structures in the marine environment causes large volumes greenhouse gas (GHG) emissions to be released. Current GHG calculation methods for offshore oil and industry infrastructure leave sources unaccounted for. results presented here show that these consequential are underreported by 50%. Until now, no study has looked at cumulative impact decommissioning, but this shows globally produced 25 MtCO2e date, around 0.5% annual global emissions. Importantly, also due growth wind industry, increasing numbers will emplaced environment, from increase 200-fold 5 GtCO2e 2067. Crucially, is not compatible with Paris Agreement, new required meet challenge.
