Our Sustainability Mindset in Action
We strive to be a valued member of the communities in which we operate. Responsible environmental stewardship is key to our sustainability mindset. We continue to prioritize protection of the environment in our operations. Par Pacific’s renewables strategy integrates environmental considerations into our decision-making processes. We leverage local resources and policies to meet local needs, striving to provide reliable, affordable, and low-carbon products to the communities we serve.
As part of Par Pacific’s commitment to sustainability and managing climate-related air risks, we continue to evaluate and refine our established business processes. These processes reduce our emissions and mitigate current and future energy transition risks to our business.
Fresh water is a critical natural resource for our everyday life. Stewarding this valuable resource involves responsible sourcing, conservation, reuse, recycling and suitable disposal.
We strive to be good stewards by mitigating our environmental impact and promoting biodiversity.

Biodiesel Tank Conversion Project
In 2024, U.S. Oil identified the opportunity to convert an underutilized storage tank to biodiesel service. Upon conversion, we are now able to import biodiesel through our rail offloading facilities and into the tank. From there, biodiesel can be fed to the truck loading rack’s ultra-low sulfur diesel (ULSD) loading arms. This has allowed our team to blend up to 5% biodiesel into all ULSD sold at the Tacoma truck rack, which provides a significant contribution to lowering the carbon intensity of ULSD sold at the refinery.
