BIODIVERSITY AND CONSERVATION Our environmental stewardship goes beyond regulatory requirements and focuses on connecting conservation efforts to our business and managing natural capital in and around the communities where we work and market our products. Natural capital encompasses the supply of the world's natural resources from which economic value and benefits can be derived, such as forests, oceans and freshwater, and the biodiversity that supports these ecosystems. We believe the careful management of natural capital is a core component of a resilient, long-term strategy. We collaborate with local and national environmental and conservation organizations to promote biodiversity and environmental stewardship and support their efforts by donating money and resources. Our employees and interns volunteer their time and make monetary contributions, many of which are matched by the company. Phillips 66 has long-standing partnerships with many national conservation organizations, including the National Fish and Wildlife Foundation, Ducks Unlimited, Trees For Houston and the Wildlife Habitat Council. We view the management of natural capital and biodiversity risks as essential. We address them throughout the planning and development of major capital projects by conducting environmental impact analyses, collecting critical environmental data, and implementing mitigation and monitoring programs to reduce impacts and ensure results. Creating Green Space The Edwardsville Children’s Museum Micro Forest project near our Wood River Refinery in Roxana, Illinois, is aiding the environment in a big way. When micro forests — small, wooded areas in urban settings — are planted, they can become a diverse ecosystem in just 20 years. This benefits biodiversity and air quality and slows stormwater runoff, helping prevent flooding and water pollution. Phillips 66 was proud to sponsor and provide volunteers to plant more than 100 trees in spring 2021. The museum hopes to have a full 2-acre forest preserve by 2033. The micro forest project also connects to a STEM forest display sponsored by the refinery inside the museum. PROTECTING WILDLIFE IN OUR COMMUNITIES We also make an annual contribution to a bird or wildlife rescue and rehabilitation organization in every region. In 2021, we donated to numerous groups, including: • Tri-State Bird Rescue and Research • The Wildlife Center of Texas • International Bird Rescue • Sutton Avian • Treehouse Wildlife Center • Wild West Wildlife Rehabilitation Center 36 PHILLIPS 66 2022 SUSTAINABILITY REPORT Wilson’s Plover GRAND ISLE, LA Edwardsville Children’s Museum Micro Forest EDWARDSVILLE, IL 36 PHILLIPS 66 2022 SUSTAINABILITY REPORT 36 OUR BUSINESSES: TODAY AND TOMORROW ENVIRONMENT AND SAFETY GOVERNANCE STAKEHOLDER ENGAGEMENT
