Confex: a mix of conference and exhibition centre

Confex – the new multi-talent
A nationally unique pilot project: Koelnmesse is set to implement CO2-free heating at one of the world’s largesttrade fair centers

Within the framework of a new energy partnership with E.ON and RheinEnergie, by 2028, Koelnmesse will have completely switched the heating supply for its exhibition centre in Cologne – the eighth largest trade fair site in the world – to climate-friendly technology. The systems used will be powered by sustainable sources such as air, groundwater and the sun. In innovative combination with the RheinEnergie district heating system, this new heating concept will secure significant energy and CO2 savings amounting to 5,800 tonnes per year. These plans form part of the sustainability strategy that Koelnmesse is launching today, which involves the company and Koelnmesse's own events reaching the requirements for climate-neutrality as early as 2030. This is five years earlier than initially planned.

On the events in Ukraine

At Koelnmesse we are closely following developments in Ukraine. The Russian attack stands in absolute opposition to our own values. As a trade fair organiser, we stand wholeheartedly for peaceful coexistence and free trade around the world.

The war has caused tremendous uncertainty and commotion regarding unrestricted service provision, monetary transactions and passenger transport between Russia, Belarus and Europe or Germany in particular. We are therefore suspending the participation of Russian and Belarusian exhibitors on our physical and digital platforms until further notice. However, we remain in contact with our partners in Russia, some of whom have been with us for many years and who unfortunately cannot attend our trade fairs now in Cologne.
