CO2 emissions have become the decisive criterion. The new federal government of Germany emphasises that future investments must be measured by how climate- and environmentally-friendly they are. This applies to all areas of the economy and society- especially the transport sector. The federal and state governments agree that, in addition to a pure change in propulsion -towards electromobility on rail and road - a change in mobility is also needed, with a significantly stronger rail system, especially in areas where public transport has not yet been strong enough. In some places, efficient public transport also requires new underground, light rail and tram lines, additional tracks, longer platforms, etc. - and thus also new rail structures such as bridges, tunnels, etc. The basic principle here must be that transport structures must be built in such a way that they can be used efficiently. The basic principle must be that transport structures are built as efficiently and emission-free as possible, but are not prevented from being built by escalating costs. An almost emission-free construction method can be expected in the long term. The decisive factor is that relevant amounts of CO2 are saved every year.
