the net abatement is then mtc eq mtchj in and mtc eq mtchj in further because of the great variations between onsite conditions individual countries must be able to use a variety of countryspecific measures to achieve the targeted reduction rates we therefore base our cost estimate on the most comprehensive assessment of global methane abatement opportunities to date the us epa report on global mitigation of nonc greenhouse gases us epa in so doing we are strictly speaking assuming that each target country will not take exactly the same measures as in norway but rather that they will implement the measures that are most costeffective for their individual circumstances in order to reach the same rate of reduction in methane intensity of oil and gas production as norway
