Our sustainable travel solutions

Switch For Green

CDS’s “Switch for Green” program supports a more sustainable approach to hotel booking in business travel. By highlighting responsible partners and offering smart search filters, the platform makes it easier for companies to align travel policies with their CSR goals. Backed by strong partnerships and a long-standing commitment to sustainability, CDS empowers clients to make informed, eco-conscious choices — without compromising on comfort or efficiency. Switch for Green is part of CDS’s broader ambition to help shape a more responsible travel ecosystem across Europe.
