Karel Harris, managing director of Sarnia Hotels, underwent the training and said: “It’s going to become more and more important and certainly some of our business guests, our corporate guests are asking what are we already doing and what plans do we have in place.”

She added: “If each one of us just makes one little change, and it can be in what we eat, it can be remembering to turn lights off, or taking a slightly quicker shower.

“It’s walking to work, sometimes, or cycling to work. There’s so many small actions we can all do, which collectively will make a difference.”

Mrs Harris said the hotel chain already have carbon offsetting schemes in place.

“We have a partnership with Guernsey Trees For Life where for every room that guests choose not to have cleaned, we make a donation of £2.

“We’ve been doing that for a year now and we will have helped to have planted 1,000 trees with this because a lot of the guests really buy into it.”
