Germany is an industrialised country with a strong production and export sector in the heart of Europe. However, German industry is dependent to varying degrees on imports of energy sources, raw materials and semi-finished products. Russia's war of aggression against Ukraine is having many consequences - from the break-up and rebuilding of previous supply chains to possible and already implemented sanctions by the EU against Russia as well as reductions in supply volumes up to a supply boycott by Russia, which are having an impact on German industry. This paper shows how operators of industrial plants, licensing authorities and the federal legislator can meet the challenges of maintaining production while reducing energy and raw material consumption. This also supports industry on its transformation pathway towards decarbonisation.
