The net abatement is then 216 (200-233) MtC02eq (6.66 MtCHJ in 2025 and 357 (323-384) MtC02eq (10.0 MtCHJ in 2030. Further, because of the great variations between onsite conditions, individual countries must be able to use a variety of country-specific 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 2013 report on Global Mitigation of Non-C02 Greenhouse gases (US EPA, 2013). 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 cost-effective for their individual circumstances in order to reach the same rate of reduction in methane intensity of oil and gas production as Norway.
