Message From Our CEO
At WES, sustainability and responsible operations are built into our corporate mission: to improve lives through safe, sustainable, and efficient energy delivery. In 2024, we continued to implement a coordinated approach to managing sustainability topics across the organization,
with a focus on protecting our people, minimizing our environmental footprint, and improving our communities.
We also continue to focus on managing and minimizing our emissions, illustrating that, even as we grow our company and increase throughput, our emissions management efforts are helping
us operate more efficiently and responsibly. We also conducted aerial flyovers over a portion of our assets to assess emissions leaks. During this effort, which was an element of our sustainability-linked corporate goals for the year, we found no new significant emissions sources.
I am especially proud of the WES employees’ focus on supporting and investing in our local communities. In 2024, we had another record year of employee participation in our social investment program, with 80% of our employees volunteering approximately 21,000 hours for more than 600 causes. In Texas, we also organized an inaugural golf tournament to support Meals on Wheels Montgomery County. This event brought together WES employees, local and industry businesses, and community members to raise over $700,000 for that charitable organization, nearly doubling our initial fundraising goal. This was just one of many efforts our people engaged in to support their local communities across our operating areas.
Looking back on 2024, I am filled with gratitude and pride by the accomplishments of our employees, and I am excited to continue our momentum on key sustainability and strategic priorities in 2025, to help us continue creating value for all of our stakeholders.
