Trees are essential for people, wildlife and the environment By absorbing CO2 from the atmosphere, trees help to combat climate change. For every guest who stays at the Hayloft, we will donate a tree to our Hayloft's grove in Scotland. We welcome donations from our guests too. One car journey (in a 1 litre petrol car) from London Paddington to Plymouth is 190 miles (0.5 tonnes of carbon). A single tree absorbs about 48 pounds of carbon in a year. We use the www.carbonfootprint.com/calculator to calculate our carbon footprint.
