Renewable Diesel and Alternative Fuels Phillips 66 provides transportation fuels that move people and goods, and as we push forward into a lower- carbon future, we are prioritizing renewable fuel projects that leverage existing infrastructure. We will process waste fats, cooking oils and other renewable feedstocks into transportation fuels. In 2021, we began producing renewable fuels from vegetable oil at our San Francisco Refinery in Rodeo, California, and we refine fuel from used cooking oil (UCO) at our Humber Refinery in North Lincolnshire, United Kingdom. In 2021, we announced that we are securing feedstock for our growing portfolio of renewable fuels projects by investing in Shell Rock Soy Processing, a new soybean-processing plant in Iowa. Additionally, we support future renewable diesel production through our agreement with New Rise Renewables in Nevada. CONVERTING OUR SAN FRANCISCO REFINERY The Rodeo facility's focus on energy efficiency was recognized in early 2020 when it became the first crude oil refinery in California to earn an Environmental Protection Agency (EPA) ENERGY STAR certification for superior energy efficiency. Now we're taking the refinery to the next phase. It's being converted to process waste fats, UCO and other renewable feedstocks. When the conversion is complete in early 2024, Rodeo will be one of the world’s largest renewable fuels facilities, able to produce more than 800 million gallons per year (over 50,000 BPD) of renewable diesel, renewable gasoline and sustainable aviation fuel (SAF). The conversion is expected to significantly reduce criteria pollutant emissions from our operations, preserve well-paying jobs and help California meet both its demand for transportation fuels and its environmental goals. To further reduce GHG emissions, the refinery is pursuing other sustainable projects, including solar power to provide electricity to run its processes and exploring carbon capture. Phillips 66 made a final investment decision in 2022 to move forward with Rodeo Renewed after the project received approval from Contra Costa County. 10 PHILLIPS 66 2022 SUSTAINABILITY REPORT San Francisco Refinery RODEO, CA 10 PHILLIPS 66 2022 SUSTAINABILITY REPORT OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT
