Report Profile

The information in this report is from the 2016 calendar year.

  • We published our 2015 Social Responsibility Report in June 2016.
  • We will continue to report annually for each calendar year.
  • The framework for defining the content of this report was determined using guidelines set by the Global Reporting Initiative (GRI) G4, Oil and Gas Sector Supplement.
  • This year’s report is different in format from previous reports – it is web-based and cannot be downloaded in its entirety as a PDF.

Defining Report Content

  • Tesoro conducted a materiality assessment in 2015 to identify the environmental and social issues that are most important to our stakeholders and to our continued success as a business.
  • As our material issues had not substantively changed since this assessment, we used these same material issues to inform our report content for 2016. To read more about the materiality and stakeholder engagement process in 2015, please read the 2015 Social Responsibility Report.
  • Per Tesoro’s materiality assessment and stakeholder engagement conducted in 2015, the following have been identified as priority issues:
    • High priority issues are safety and asset integrity, oil spill prevention and response, air emissions, and business ethics and transparency.
    • Moderate priority issues are hazardous and nonhazardous waste, water usage, climate change, community impacts, social investment, the extent to which Tesoro is an attractive employer, supply chain, workforce development, shared benefits, biodiversity and ecosystems, diversity and inclusion, renewable energy and human rights.
