Building a bright and sustainable future for the communities, customers and employees that we are so proud to serve.


Delivering on a profound responsibility to create solutions that accelerate a sustainable future for those we serve.

Deep in our Company’s heart is a desire to lead positive change in all that we do. While providing essential natural gas services, our commitment to responsibly advancing environmental, social and corporate governance (ESG) efforts further drives our success. Here, our board and management team provide the oversight needed to help ensure these directives are met and that we uphold the greatest integrity in doing so.
In 2020, we expanded our ESG reporting framework to include Sustainability Accounting Standards Board (SASB) metrics, which enhance the standardization of our reporting and ultimately aid in the external assessment of our business.

Building Sustainable Practices

As our business expands, we continue building upon our sustainable environmental practices. In 2021, we embarked on a critical evaluation of the pathways to attaining shared emissions-reduction goals in our service territory. Demonstrating progress in this area, we continue to actively reduce our carbon footprint through improvements to our fleet and building facilities. We have also made significant progress in delivering low-carbon fuels to the marketplace through renewable natural gas (RNG) projects and hydrogen blending pilot programs.
All this comes while maintaining critical reliability and an inherent ability to withstand the tests of outside forces. When severe winter weather curtailed interstate natural gas deliveries in early 2021, our liquified natural gas (LNG) plant in Tucson, Arizona, proved its resilience as a reliable energy source in unlikely high-impact events. Similarly, with the importance of cybersecurity broadening in the utility space, we are elated to see our proactive enhancements in digital safety credited by CSO for combining resilience and innovation while protecting confidential data.

Prioritizing Our Communities

As a Company, we continue to prioritize our efforts to mitigate the pandemic’s impact on the communities where we live and work. In early 2021, Southwest and Centuri put forth a collaborative effort toward the COVID-19 vaccine rollout, partnering with a local nonprofit in Arizona to administer over 18,500 doses in five days. Combined with the myriad of volunteer efforts we participate in throughout the year, we are heartened by how our employees’ dedication continues to evolve, invariably reaching new and meaningful heights. Our employees selflessly gave a remarkable $2.2 million to over 220 local nonprofits in 2020, assisting when and where our communities needed us most.
Together, our strong focus on social responsibility has empowered us to take significant steps forward. We continue to build upon our diversity, equity and inclusion (DE&I) efforts by continuing to announce new commitments to advance our Company’s collective strategy.
By including the many diverse views that comprise Southwest Gas, we can forge a bright future that we all take pride in sharing. To build a better tomorrow, we remain committed to acting with diligence today.
