Southern Company Gas Subsidiaries Complete New Renewable Natural Gas Purchases

Southern Company Gas' subsidiaries, Virginia Natural Gas and Chattanooga Gas, have completed new renewable natural gas (RNG) purchases, expanding their portfolios of clean and sustainable fuel. These transactions are estimated to avoid 18,978 metric tons of carbon dioxide equivalent (CO2e) in lifecycle emissions, equivalent to the carbon sequestered by 19,036 acres of U.S. forests in one year. This initiative aligns with Southern Company Gas' goal of achieving net-zero direct greenhouse gas emissions from operations by 2050.

Key Takeaways:

• Southern Company Gas' subsidiaries, Virginia Natural Gas and Chattanooga Gas, have completed new RNG purchases, adding to their portfolios of clean and sustainable fuel.
• The total lifecycle emissions avoided by these transactions are estimated to be 18,978 metric tons of CO2e, equivalent to the carbon sequestered by 19,036 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, RNG significantly reduces greenhouse gas emissions, making it fully compatible with existing natural gas infrastructure and appliances.
• This purchase follows the utilities' first-ever RNG purchases in 2023, made possible by supportive policies in Virginia and Tennessee, including the Virginia Energy Innovation Act and the Tennessee Natural Gas Innovation Act.
• Southern Company Gas aims to achieve net-zero direct greenhouse gas emissions from operations by 2050, with the RNG purchases being a step towards this goal.

Statistics:

• 18,978 metric tons of CO2e: The total lifecycle emissions avoided by these RNG purchases.
• 19,036 acres: The equivalent amount of U.S. forests that can sequester the same amount of carbon as the RNG purchases in one year.
• 190,000 tons: The estimated reduction in greenhouse gas emissions over the production lifecycle of the RNG.
• 2023: The year when Southern Company Gas made its first-ever RNG purchases.
• 2050: The target year for Southern Company Gas to achieve net-zero direct greenhouse gas emissions from operations.
