RESILIENCE AND ADAPTATION We maintain and test robust business continuity planning and preparedness programs and other initiatives. Examples include: • Hardening assets to enhance their reliability, including our industry-leading pipeline river crossing program and the power substation elevation at Bayway Refinery in Linden, New Jersey • Installing a state-of-the-art power distribution facility at Wood River Refinery in Roxana, Illinois, improving facility reliability and reducing flaring from unplanned events • Providing comprehensive community awareness, education and outreach programs to ensure that everyone living or working near pipelines or facilities is aware of their existence, adopts safe digging practices, learns the signs of a potential pipeline leak and knows how to respond quickly if a problem is suspected GHG METRICS AND TARGETS The majority of our GHG emissions are from refining. Our goal is to improve our operational excellence, improve our energy efficiency and reduce our GHG emissions intensity. We have set a goal for our refining sites to achieve top-third energy efficiency by 2030. We use a third-party industry manufacturing energy-efficiency index to measure our progress. In the fall of 2021, Phillips 66 became an ENERGY STAR Partner to reflect our commitment to improving energy efficiency. Our refineries process a combined average of about 2 million barrels per day of crude oil into clean, affordable everyday energy products. Most of our Scope 1 GHG emissions are CO 2 , resulting from manufacturing energy products. Our methane and other GHG emissions are negligible. More stringent regulatory standards can require more processing, which takes more energy. 52 PHILLIPS 66 2022 SUSTAINABILITY REPORT 52 PHILLIPS 66 2022 SUSTAINABILITY REPORT OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT Sweeny Hub Fractionator 4 OLD OCEAN, TX
