Environmental Strategy Overview

Atmos Energy's comprehensive environmental strategy is focused on reducing our Scope 1, 2, and 3 emissions and environmental impact from our operations in five key focus areas: Operations, Fleet, Facilities, Gas Supply, and Customers

We are implementing operating practices and solutions to reduce carbon from our operations through:

Ongoing system modernization work

Reducing third-party damage to our system

Improving monitoring and measuring of methane emissions

Expanding supply options and opportunities including renewable natural gas (RNG)

Expanding customer energy efficiency programs

Exploring clean energy technologies through research and development

Collaboration with our legislators, regulators, customers, and suppliers

Future carbon reduction targets will be established based upon existing legislation, regulation, and technologies

For more information, see our latest CRS report: atmosenergy.com/sustainability/

The ONE Future Coalition is a group of more than 50 natural gas companies working together to voluntarily reduce methane emissions across the Natural Gas value chain to 1% (or less) by 2025. ONE Future is actively developing the next phase of methane-reduction goals. In 2024, overall methane intensity decreased to 0.28%, a 15.4% decrease in intensity

from 2023.

Supporting research and development initiatives to further reduce emissions

Accelerating the commercial deployment of low- and zero-carbon technologies

from 2030 to scale through 2050 for economy-wide deep decarbonization

The Coalition for Renewable Natural Gas is a public policy advocate and education platform for the RNG industry in North America.

Sustainable Methane Abatement & Recycling Timeline (SMART) is an initiative to capture and control methane from 43,000+ organic waste sites in North America by 2050, achieving significant benchmarks by 2025, 2030 and 2040.
