Gas plants and infrastructure emit nitrogen oxides (NOx) during combustion, which degrade local air quality. Gas plants and their associated infrastructure, including pipelines, production wells, and compressor stations, have had an extremely harmful impact on public health and the environment. First, there’s air pollution.
