The donation is part of the Association’s efforts to offset its carbon footprint in hosting the annual conference Liverpool, from 6-8 June.
A 500 square mile area is covered by the long-term tree planting programme that was established in the early 1990s.
“We are very conscious that hosting a large conference and bringing more than 1,000 people to the city of Liverpool will have a significant impact on the local environment,” said Susi Ozkurt, Airmic’s Head of Events.
“It is with this in mind that we have chosen to make a donation to Mersey Forest, a local initiative that does great work in planting trees in urban spaces.”
The Mersey Forest has planted more than nine million trees in the Forest area and has been praised for bringing a host of environmental, health and economic benefits.
