Title:	Klimaschutz im Verkehrswegebau - Ausbau der Infrastruktur in Deutschland
Abstract:	Der CO2-Ausstoß ist zum entscheidenden Maßstab geworden. Die neue Bundesregierung betont, dass Zukunftsinvestitionen sich daran messen lassen müssen, wie klima- und umweltfreundlich sie sind. Das betrifft alle Bereiche von Wirtschaft und Gesellschaft - gerade auch den Verkehrssektor. Bund und Länder sind sich hier einig, dass es neben einer reinen Antriebswende - hin zur Elektromobilität auf Schiene und Straße - vor allem auch einen Mobilitätswandel braucht, mit einem deutlich stärkeren Bahnsystem gerade dort, wo der ÖPNV bislang noch nicht ausreichend stark war. Für einen effizienten ÖPNV braucht es mancherorts auch neue U-Bahn-, Stadt- und Straßenbahnlinien, ergänzende Gleise, längere Bahnsteige etc. - und damit auch neue Schienenbauwerke, wie Brücken, Tunnel etc. Grundsatz muss hierbei sein, dass Verkehrsbauten zwar einerseits so effizient und emissionsfrei wie möglich hergestellt, aber andererseits auch nicht durch ausufernde Kosten verhindert werden. Eine nahezu emissionsfreie Bauweise ist dabei eher langfristig zu erwarten. Entscheidend ist, dass jedes Jahr relevante Mengen an CO2 eingespart werden. Climate Protection in Transportation infrastructure Construction - infrastructure expansion in Germany 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.
