Hess Midstream LP published the 2022 Hess Midstream Sustainability Report in December 2023 as part of our commitment to transparency about environmental, social and governance plans and performance. Leading sustainability reporting frameworks were used to develop the report, including the Energy Infrastructure Council (EIC) and GPA Midstream Association Environment, Social and Governance (ESG) Reporting Template, the Sustainability Accounting Standards Board standard for oil and gas – midstream, the Taskforce for Climate-Related Financial Disclosures and the Global Reporting Initiative (GRI) Standards. The 2022 Hess Midstream Sustainability Report is a companion to the 2022 Hess Corporation Sustainability Report, which provides greater detail on the sustainability strategy, management systems and programs for Hess Corporation that also apply to Hess Midstream.
