**4.7 Benefits of ComplexTrans to reduce energy consumption and emissions and protect the climate**

The ComplexTrans system can be powered entirely by electricity, partly by hydrogen produced from water using electricity. If all sources of electricity are renewable, ComplexTrans ground transport will become fully renewable and completely emission-free.

The ComplexTrans system is capable of transporting all passengers and most of the goods, carried by the freight transport modules, using only electricity and largely by rail, consuming less energy.

The ComplexTrans rail transport is also capable of completely replacing continental air transport up to a distance of about 3000 km and replaces the fossil fuels by electricity.

Large and heavy goods will continue to be transported by trucks or sea containers. Also semitrailors and containers are transported on the ComplexTrans system by fast electric rail waggons, and first and last mile services may be provided by electric or hydrogen powered trucks.

Thus, the vast majority of passenger and freight transport can be provided emission-free by ComplexTrans.
