Kogas and Tata Daewoo, Korea's second-largest truck manufacturer, will test the vehicle at the gas firm's operation in Tongyeong, South Gyeongsang, and at a gas charging station in the central city of Daejeon. The gas firm said it will step up efforts to promote LNG trucks as a more eco-friendly and economically viable alternative to diesel vehicles. If half the 120,000 diesel vehicles over eight tons are replaced with LNG trucks, it would reduce fine dust emissions by 1,474 tons in Seoul, it added. Kogas vowed to expand natural gas charging stations in major ports, cargo terminals and highway gas stations and to consult with the government to expand subsidies and incentives for LNG commercial vehicles.
