Earth Day serves as a global reminder of the importance of environmental stewardship. At Marathon Petroleum, guided by our Core Values, we work to demonstrate our unwavering commitment to safe and environmentally responsible operations every day. We celebrated Earth Day 2025 with a variety of activities and community investments across many of our locations across the country. From tree planting and educational events to significant donations for environmental projects, Marathon Petroleum's focus on sustainability and community engagement shines through.
