Koelnmesse aims to achieve carbon neutrality by 2030 with a strong focus on energy supply as a key element of its strategy. The company is concentrating on expanding photovoltaic (PV) systems and developing alternative heating solutions. Since 2015, Koelnmesse has integrated sustainability into its modernisation and construction projects, organising its efforts into three strategic pillars: nature, events, and community. A major goal is to reduce energy consumption while increasing the use of renewable energy sources on its exhibition grounds. Additionally, Koelnmesse is developing a new heating concept in collaboration with energy provider E.ON, aiming to completely eliminate the use of fossil fuels.
