About
The Oil Climate Index plus Gas (OCI⁺) is an open-source analytic tool that estimates and compares the life-cycle greenhouse gas (GHG) emissions intensities of a majority of oil and gas resources worldwide from supply chain segments including production; refining and petrochemical processing; gathering, to storage and transport; and end use consumption of petroleum products. This climate intelligence is used to differentiate the variation of heterogenous oil and gas resources across various stages of the supply chain.
The OCI⁺ is designed to inform a diverse set of stakeholders, policymakers, industry, financal institutions, NGOs, and civil society. By making oil and gas climate impacts visible and quantifiable, the OCI⁺ provides strategic inputs stakeholders can use to make more secure decisions about oil and gas development, operations, regulations, investing, and infrastructure planning.
The OCI⁺ has been updated and expanded over the course of a decade. While originally developed as an oil-centric tool to alert public and private stakeholders to the full array of oil’s climate impacts, the model was expanded in 2021 to include global gas resources.
Please let us know if there are use cases you need that we should consider in our future tool development efforts.
