Greenhouse Gas Emissions from Heavy-duty Natural Gas Vehicles in Korea
Abstract Since 1991, heavy-duty natural gas vehicles (NGVs) have been supplied as an alternative to heavy-duty diesel vehicles (HDVs) in Korea. This study calculated the emissions from 40 compressed natural gas (CNG) buses by using a backward-looking vehicle simulation model; based on these results,...

| Summary: | Abstract Since 1991, heavy-duty natural gas vehicles (NGVs) have been supplied as an alternative to heavy-duty diesel vehicles (HDVs) in Korea. This study calculated the emissions from 40 compressed natural gas (CNG) buses by using a backward-looking vehicle simulation model; based on these results, the total heavy-duty NGV GHG emissions in the country were estimated to be 1.66 million tons annually, which contributes 6.75% of the total national GHG emissions from HDVs. Compared to diesel HDVs in a similar weight class, heavy-duty NGVs emit 6.3% less GHG—or 39.3 tons less per vehicle annually—on average. |
