Chattanooga Gas expands clean energy portfolio with new renewable natural gas agreement
Lifecycle emission reductions estimated to be 3,416 metric tons of CO2e, equivalent to the carbon sequestered by 3,426 acres of U.S. forests in one year
CHATTANOOGA, TN – June 25, 2025 – Chattanooga Gas has completed a new renewable natural gas (RNG) purchase, further enhancing its portfolio of clean, sustainable fuel. The lifecycle emissions avoided by this transaction are estimated to be 3,416 metric tons of carbon dioxide equivalent (CO2e), which is equivalent to the carbon sequestered by 3,426 acres of U.S. forests in one year.
RNG is a sustainable product produced from naturally occurring methane emitted from landfills, agricultural waste, wastewater and food waste as it decomposes. By capturing this methane before it enters the atmosphere, RNG significantly reduces greenhouse gas emissions. This fuel is fully compatible with existing natural gas infrastructure and appliances, providing a seamless transition to a more sustainable energy source.
“This agreement strengthens our commitment to providing our customers and communities with fuel that is clean, safe, reliable and affordable," said Walt Farrell, president and CEO of Chattanooga Gas. "By incorporating renewable natural gas into our innovative energy portfolio, we are not only addressing our customers' expectations for sustainable solutions but also demonstrating our dedication to our goal to achieve net zero operational emissions by 2050. This is just one of the many initiatives we are implementing to ensure a cleaner, greener future.”
This purchase involves acquiring environmental attributes from facilities in Texas. It follows the company’s first-ever RNG purchase in 2024. The agreement was made possible by the passage of supportive policies in the state. The Tennessee Natural Gas Innovation Act permits natural gas utilities to pursue cleaner energy options and allows incremental innovative natural gas costs to be reflected in the utility’s purchased gas adjustment.
