Caring for Our People. Caring for Our Planet.
At the center of our responsibilities as a company are the people we serve, our environment and the leaders and organizations in our communities. This includes a focus on sustainability as a natural extension of Southern Star’s vision of one community working together to be the leading provider of clean, safe and reliable energy for tomorrow. Through innovation and partnership, Southern Star remains committed to being a leading partner in delivering your energy needs both now and tomorrow.
48% reduction in methane emissions since 2020
26% reduction in greenhouse gas emissions since 2020
As demand for sustainable energy continues to grow, Southern Star is positioned to continue meeting the needs of the communities where we live and work through responsible environmental, social and governance practices.
Environmental Stewardship
We are dedicated to finding ways to reduce energy and water consumption at our facilities, restoring areas impacted by construction back to their original state, and increasing recycling efforts across our system.
Southern Star is committed to a 50-percent reduction of methane emissions by 2025. Southern Star is a member of the ONE Future coalition which uses science-based technology and methods to reduce emissions across the entire natural gas supply chain. Further, as a member of the Interstate Natural Gas Association of America (INGAA), we are committed to methane emission reduction initiatives by increasing leak surveys, reducing bleeding pneumatic devices, and increasing focus on rod packing leaks and changeouts.


Social Responsibility
Southern Star serves our communities through outreach efforts, engagement, and partnerships. We help fuel the quality of life within the communities where we work and operate through volunteerism and corporate giving. Team members give their time and talent to local non-profit and youth organizations across our footprint, including STEM and robotics programs in local schools.
Governance
Strong, ethical leadership is the foundation of Southern Star’s culture of safety, reliability, and sustainability. At every level, Southern Star team members are empowered to take responsibility and accountability in the operation of our transmission system.

Project Highlights
Hydrogen Pilot Project
In 2022, Southern Star launched the “H2 Pilot Project,” which involves using a hydrogen-blend fuel in a natural gas reciprocating engine at the Hugoton, Kansas compressor station. Southern Star is the first natural gas transmission company in the United States to utilize hydrogen as a component in its fuel to reduce its carbon footprint. Our team continues to find unique opportunities to ensure we continue to deliver the service customers count on as the energy sector evolves.
Solar Arrays & Charging Stations
Our first solar array was installed at Southern Star’s headquarters, generating enough electricity to offset the facility’s power demand. This addition made our headquarters the first known net zero carbon-based energy facility of its size in Owensboro, KY. We continue evaluating other locations for further solar array enhancements, like our newest solar array in Welda, KS. Southern Star has also sponsored several solar charging benches in our local parks and communities to provide sustainable charging stations for our neighbors.
Community Tree Plantings
Every year, Southern Star team members across our system take the opportunity to plant new trees for local community parks and organizations. Through these efforts, our team shares our focus on building a sustainable future with the people we serve one sapling at a time.
