however reported methane emissions are often based on production volumes and standard emission factors in large part derived from us epa work iea the year global warming potential cited here is most commonly used but in scenarios where climate change impacts become severe already in the near term one could argue that a higher value shorter time scale should be used according to the industry itself this is not primarily the result of a specific focus on reducing methane leakages but rather due to strict safety regulations and highquality equipment statoil all oil and gas production in norway also takes place offshore which requires greater attention to pipe sealing and equipment durability than onshore production we do estimate what the impact of this would be but do not use it as the main scaled abatement potential for this solution by this had gone down to kgch tj an average reduction of peryear
