This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
HF Sinclair operates a refining and marketing business with a carbon intensity that ranks in the bottom half of its industry peer group. In 2024, the company placed 16th out of 25 companies in its sector based on Scope 1 emissions intensity. Its most ambitious operational climate target is a 25% reduction in net greenhouse gas emissions intensity by 2030.
The company has a documented pattern of criteria air pollutant violations at its facilities. In January 2025, HF Sinclair Navajo Refining LLC agreed to a settlement with the U.S. Department of Justice and EPA for violations of the Clean Air Act. The lodged complaint alleged failures to monitor and control emissions of hazardous air pollutants, including benzene and volatile organic compounds, and cited violations of National Emissions Standards. This enforcement action addresses systematic failures at the facility to provide accurate emissions data and control releases of known carcinogens.
HF Sinclair Corporation operates as a major independent petroleum refiner and marketer in the United States. The company derives substantially all of its revenue from refining crude oil into transportation fuels and other products, operating refineries in Kansas, Oklahoma, New Mexico, Utah, Washington, and Wyoming. Its business includes the marketing of refined products under the Sinclair brand through a network of approximately 1,500 branded wholesale locations and travel centers.
The company was formed through the 2022 combination of HollyFrontier and Sinclair Oil, creating a new downstream parent entity, HF Sinclair Corp. This merger consolidated significant refining and marketing assets, including the acquisition of Sinclair Oil's branded marketing business and its related logistics network. The company's operations are concentrated in the refining and sale of gasoline, diesel, jet fuel, and other petroleum-based products.
HF Sinclair has been involved in ongoing climate litigation. In November 2023, a settlement between HF Sinclair and Shell was noted as having resolved Sinclair's claims against the Delaware Department of Natural Resources and Environmental Control related to such proceedings. The company's core business model remains focused on the processing and sale of fossil fuels.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
