"Sustainability is crucial to our airports’ success, and as we plan for the future we are committed to using the most sustainable features and processes possible. We are ensuring a better future for the next generation, and that’s creating a great Nashville Airports Experience for our passengers, business partners and employees."

Raul Regalado, MNAA’s President & CEO

(Quote from Airport World article: “Nashville Keeps Sustainability a Top Priority.”)

"This historic project will significantly reduce our electricity usage and potable water consumption, which will result in substantial annual utility savings. This is the very essence of sustainability."

- Rob Wigington, MNAA President, CEO

Through a two-phase energy performance contract, ESG helped the airport modernize infrastructure while reducing operating costs via lighting upgrades and other sustainability measures. The geothermal lake plate cooling system project represented a third collaboration highlighting the airport's commitment to energy efficiency - delivering savings while exemplifying how airports can advance environmental responsibility.


This project ultimately enhanced sustainability, cut costs, and demonstrated the airport's dedication to responsible energy practices.
