GRI G4 Indicator Index

Tesoro utilizes two sources as the primary framework for reporting its sustainability performance: 1) the Global Reporting Initiative’s (GRI) General Guidelines and Oil and Gas Sector Supplement (version 3.1) and 2) “Oil and Gas Industry Guidance on Voluntary Sustainability Reporting” (2015), developed by the International Petroleum Industry Environmental Conservation Association (IPIECA), the International Oil and Gas Producers Association (OGP) and the American Petroleum Institute (API). These guidelines are used as a basis for selection of specific disclosures intended to provide stakeholders with relevant information on topics of concern. View a full listing of GRI indicators here.
