Reporting of greenhouse gases by major sources is required by the California Global Warming Solutions Act (AB 32, 2006). The regulation affects industrial facilities, suppliers of transportation fuels, natural gas, natural gas liquids, liquefied petroleum gas, and carbon dioxide, operators of petroleum and natural gas systems, and electricity retail providers and marketers. All GHG reports must comply with the regulatory requirements and be submitted via the Cal e-GGRT reporting system.
