Sustainability specialist Greengage has joined the One Global TMC network as a preferred supplier.

Based in the UK, Greengage offers sustainability consulting services to corporates looking to reduce their carbon footprint as well as its ECOsmart sustainability certification platform for hotels and meeting venues.

Existing partners and clients of One Global will now be able to access the ECOsmart platform to either attain certification (for hotel supplier partners within the network) or assess the sustainability credentials of potential suppliers during a sourcing exercise.

Additionally, Greengage¡¯s carbon measurement tool Eventsmart, which can assess the carbon footprint of meetings and events, will also be made available.

Andrew Perolls, CEO of Greengage, said: ¡°We want to establish a world beating sustainability proposition that provides competitive differentiation to One Global partners¡­ There¡¯s a real opportunity to leap ahead of other international TMC networks with a common global approach to responsible corporate travel.¡±

One Global managing director Jodie Gentles added: ¡°Sustainability plays a big part in our strategy at One Global and to be able to now count upon Greengage on our journey forward will be invaluable, especially as we work collaboratively to achieving sustainable net-zero-goals.¡±

One Global Travel is the 13th largest network of travel management companies operating in Europe, according to BTN Europe¡¯s Leading TMCs 2025 report.
