The Natural Gas Supply Collaborative (NGSC) is a voluntary collaborative of natural gas purchasers that are promoting safe and responsible practices for natural gas supply. Natural gas plays a vital role in the U.S. energy mix. This abundant domestic resource currently provides significant economic and environmental benefits to customers in the electric power, residential, industrial and commercial sectors and across the U.S. economy. At the same time, as public-facing companies in the natural gas value chain, electric generators and natural gas utilities face questions from the public, regulators, investors, and other stakeholders concerning natural gas production.

ERM is convening and managing the collaborative and overseeing development and release of all products of the collaborative.
