The independent agency announced a new campaign - "It’s not easy being green" - to urge clients to travel responsibly wherever they go. 

Available on TravelTime World’s website, the responsible travel guide includes tips such as reducing the use of plastic, as well as travelling light and being conscious of local customs. 

The agency’s staff said they will follow up when customers return from their travels, using a short survey to check whether they have “travelled responsibly.”

The mission comes as TravelTime World has launched its first ESG policy, which sets out the agency’s commitment to sustainability. 

The company has also pledged to produce an annual report to reflect its environmental impact over the previous year and to plan ahead to reduce it.

“We want to make sure we’re able to have the same experiences in thirty years’ time, for our children and grandchildren to enjoy just as much as we have been able to,” said its innovation director Ashley Quint.

“For them to lie on the same beach in the Maldives, visit the same indigenous community in Fiji or see the coral at the amazing Great Barrier Reef.”

Quint said TravelTime World was aspiring to reach B Corp status, a certification given to businesses making a positive impact on their staff, communities, customers and the planet, and had "taken our first steps" by completing an initial assessment.

"It’s our ambition to be one of the first travel agencies in the UK to reach this standard," he said. "We realise there are not necessarily right answers to everything, and the path might change along the way.

"However, what we can say is that we are committed to playing our part in making travel a force for good, one which both respects our environment and makes a positive contribution to communities around the world."
