Priority Planning for Methane Emissions Abatement via Marginal Abatement Cost Curves (MAC) and Shapley-Shubik Power Index

Methane is the second largest emitted greenhouse gas next only to carbon dioxide. Methane is also a more potent greenhouse gas with higher global warming potential. The oil and gas sector is a major contributor to the methane emissions. Given the impact of methane emissions on global warming, there is an urgent need to report and mitigate these emissions from the sector. This necessitates the need for systematic tools to strategies the methane emissions reduction. This work proposes an integrated marginal abatement cost (MAC) and Shapley-Shubik methodology to determine the most cost-effective selection and deployment strategy of methane abatement technologies to meet the set emissions reduction targets. A case study from the Malaysian oil and gas sector is used to demonstrate the applicability of the aforementioned methodology.
