Thomas Cook is extending its celebrations for World Environment Day to last the whole of this week.

The United Nations event, which aims to focus the world’s attention upon the need to look after the planet, will be held this Friday, June 5.

However, the operator is kicking off its own week-long celebrations today with employees both in the UK and overseas undertaking a number of activities to help the environment.

Thomas Cook acting head of sustainability Soeren Stoeber said: “We take our responsibilities to embrace green travel initiatives very seriously.

“Making travellers aware of the local communities they are visiting and the positive impact their holiday can have is all-important.

“It is up to companies like Thomas Cook to educate both our employees and guests about the environmental impact of travel and ensure that we are offering the most effective sustainable options when it comes to leisure travel.”

Events planned for the week by Thomas Cook staff include a beach clean up in Paphos harbour, a sustainable tourism fashion show and a clean up of Flower Street in Sunny Beach, Bulgaria.
