The techniques and technologies involved in reducing exhaust emission levels from aircraft gas turbine engines are examined and current pollution levels are compared with other modes of transport. The nature of gas turbine emissions and the available technology for reducing emission levels are discussed. A pollution comparison in traveling from London to Paris by air and via the Channel Tunnel is made. The first two routes compared were by air and by the through train from Waterloo to Paris (Gare du Nord Station); both of these routes offer journey times of approximately three hours and would therefore compete for a similar market. The entire rail network will be electrified between the two capitals, and hence the power station emissions produced in providing the energy to move the strains was included. With the exception of sulphur dioxide emissions (produced from power stations), the emissions per passenger in traveling by train are substantially lower than going by air. To complete the study, a third route was examined. This route is by petrol vehicle utilizing the Tunnel Shuttle. Comparisons of the emissions per passenger illustrated that travelling by car is the most damaging form of transport in terms of effect on the environment.
