Among the types of automobile that are currently commercially viable, Tokyo Gas is working to popularize the use of clean, low CO2
-emitting natural gas vehicles (NGVs). We are also helping to develop the hydrogen supply infrastructure to assist the spread of fuel cell vehicles, which emit no CO2
at the combustion stage, in order to diversify fuel use.
Number of NGVs in Use(in Tokyo Gas's Service Area)
■Popularization of NGVs
There are presently about 46,000 NGVs on Japan's roads (as of March 2017), and their numbers are steadily growing. In fiscal 2016, a further 532 NGVs (primarily trucks and garbage trucks) appeared on the roads in our service area alone. As of the end of March 2017, there were 16,737 NGVs in operation in our service area. In addition, there were 75 natural gas stations (including 13 fueling stations used solely by buses or delivery vehicles) in our service area.
■Environmental friendliness of NGVs
* Diesel limits are for diesel vehicles weighing over 3.5 tons GVW.
As NGVs use natural gas as fuel instead of diesel or gasoline, they emit only small quantities of NOx and virtually no black smoke or SOx. They produce about 10%-20% fewer CO2
emissions than gasoline vehicles and are receiving positive coverage as environmentally friendly vehicles.
NGV Exhaust Performance

NGVs' environmental friendliness and superiority in terms of improved energy security make them a highly viable alternative to gasoline vehicles, and NGV cargo trucks, buses, garbage trucks, vans and other vehicles are already in widespread use on urban roads. With fuel diversification needed in the long-distance inter-city road haulage sector, too, Isuzu Motors Ltd. released a new heavy-duty CNG truck in December 2015, followed by additional models in November 2016. As a result, CO2 emission reductions and fuel diversification can now be achieved throughout the logistics sector.
