Tokyo Gas Group has been creating and enhancing LNG value chains for over four decades, and highly environmentally friendly, securely suppliable, and versatile natural gas is at the core of our business development. Below we explain the benefits of the natural gas and city gas systems that form the foundations of the Group's business.
Natural gas consists mostly of colorless, odorless, clear methane, which produces less carbon dioxide (CO2) when combusted than other fossil fuels like oil and coal. It also produces lower nitrogen oxides (NOx) emissions, which are a cause of photochemical smog, and no sulfur oxides (SOx), which cause asthma and acid rain, giving it significant potential as a clean and environmentally friendly energy source.

There are abundant reserves of natural gas around the world, and "unconventional" natural gas reserves are also being developed today, especially in North America. Technological innovations have made possible the commercial development of these previously unprofitable resources, broadening the potential for sourcing stable supplies of cheaper natural gas and thereby greatly improving supply security.
Significantly, we source our LNG primarily from Southeast Asia, which makes us less dependent on the Middle East. Although LNG demand is rising worldwide, our involvement in upstream gas field projects and our receipt of LNG from them gives us secure access to competitively priced LNG procurement sources.
