The EU is targeting a 75% reduction in carbon dioxide emissions per passenger kilometer between the years 2000 and 2050. Core exhaust loss. The “Core exhaust” loss is primarily due to thermal energy lost to the surroundings, although some excess kinetic energy and fluid friction associated pressure losses contribute as well.
