The American Gas Association (AGA), founded in 1918, is an American trade organization representing natural gas supply companies and others with an interest in the manufacturing of gas appliances as well as the production of gas. About 92% of the 70 million natural gas customers in the US receive their gas from AGA members.
The association contains two divisions, operations and engineering, and public affairs. These two divisions work together to handle finance, corporate affairs, communications, and membership departments to deliver timely and relevant information to association members. The AGA also works with lawmakers, regulatory bodies, environmental and consumer affairs organizations, and the public at large, informing them of the natural gas utility industry in the United States.
