The building industry is the main source of carbon dioxide emission worldwide. In particular concrete infrastructure is responsible for a great part thereof, with 8% to 9% of the global carbon dioxide emissions being traced back to cement production. In these times of climate crisis, new strategies have to be deployed to reduce the carbon footprint. The present paper addresses the potential application areas of carbon fiber-reinforced polymer (CFRP) reinforcement in concrete infrastructure engineering. In the first part an overview of the very diverse European market of FRP manufacturers is given to prove the availability and to highlight challenges for a broad application. The second part addresses potential application areas with a main focus at fields where either the high corrosion resistance or the low required concrete cover allowing for a mass reduction is advantageous. In the third part a static parametric study is presented. A simple structure was examined in terms of the load-bearing capacity and the serviceability with the results being compared to ordinary RC-structures. By assigning the material consumption to characteristic values of the Global Warming Potential (GWP) for the various building materials, the eco-efficiency is highlighted. The results of the research can then serve as a decision-making tool whether a concrete structure should be built using non-metallic reinforcement or ordinary steel-reinforcement.
