The Shinkansen, Japan's bullet trains, are electric, so there are no carbon emissions while running. The electricity used comes from a variety of sources, including renewable and nuclear, which have very few emissions. As well as this, the modern trains, eg, the N700A, uses 19% less energy than the 1999 models because of clever developments in technical areas such as regenerative braking and computer speed control.
