Managing Air Emissions

As good stewards of the environment, we seek to responsibly manage our impact on critical natural resources. We’re committed to meeting or exceeding all applicable federal, state and local air emissions requirements. Beyond full regulatory compliance, we support effective, voluntary programs to reduce greenhouse gas and criteria air pollutant emissions. We further manage emissions by maximizing operational efficiencies and implementing industry best practices.


An annual greenhouse gas inventory is prepared and submitted to the Environmental Protection Agency (EPA) for our midstream gathering, natural gas processing and interstate transmission and storage operations. Combusted, vented and fugitive greenhouse gas emissions are tracked and reported to the EPA using their methodologies. We calculate and report our facilities’ annual criteria air pollutant emissions to the applicable regulatory agencies in accordance with permit requirements.

Williams recognizes the important role natural gas can play in helping to address environmental concerns about air quality and climate change, particularly when it comes to displacing more polluting fuels.

Natural gas is a flexible, lower-emission fuel compared to other hydrocarbons such as coal or heating oil. Because the United States has an abundant supply of natural gas, using this local, cleaner resource can help reduce the country’s demand for foreign energy sources, create jobs and reduce emissions.

As we seek to maximize natural gas resources to meet growing demand, we are working to reduce greenhouse gas emissions from our operations. In addition to complying with regulations, we support effective voluntary programs to reduce emissions and increase transparency of greenhouse data.
