At Congrex, we believe that sustainable hotel booking an effective way to reduce the environmental impact of international conferences. Every small choice matters, especially when thousands of participants travel, stay, and engage together.

That is why we now offer a new option for delegates to easily prioritise eco-friendly accommodation during the booking process. This supports our ongoing commitment to conference travel sustainability across all events we manage.

Why Sustainable Hotel Booking Matters

For many of our clients and their delegates, sustainability is no longer a “nice-to-have”, it is a priority. With our new filter for sustainable hotel booking, participants can now select accommodation based on environmental practices such as energy efficiency, waste reduction, and responsible sourcing. Many of these hotels are certified by programmes like Green Key or the EU Ecolabel.

This functionality is made possible through our integration with HotelMap, a global platform that specialises in modernising hotel booking for conferences and group travel. With this technology, the “Green Hotels” toggle is seamlessly built into the booking experience, making it simple and intuitive for delegates to align travel with their values.

How Congrex Supports Greener Travel

This new option complements our wider mission at Congrex: to offer smarter, more responsible services that enhance the delegate experience. As a full-service PCO, we provide hotel booking for events through centralised services that make logistics simple – and now, more sustainable. Learn more about our delegate accommodation services.

From accommodation to venue selection, we continuously evolve our services to reflect client needs and social responsibility. Read more about our eco-friendly practices for sustainable conferences.

Part of a Broader Sustainability Strategy

This feature is one part of our broader approach to sustainable event management. Whether it is reducing printed materials, supporting green venues, or providing digital solutions, our goal is to make every aspect of your conference more conscious and future-ready.

We also align our efforts with the UN Sustainable Development Goals, particularly those focusing on responsible consumption and climate action. Learn more about our values and long-term efforts on our Sustainability & CSR page.
