Manchester Airport has become the first organisation of its kind in the UK to achieve the carbon neutral status.
It has invested more than £7.5 million in energy efficiency projects over the last decade in a bid to reduce its energy use.
That includes installing more than 25,000 LED lights throughout the airport, which helped save the same amount of energy as used by 10,000 homes annually.
The carbon neutral status has been certified by the independent carbon management programme Airport Carbon Accreditation.
Ken O’Toole, CEO of Manchester Airport said: “At Manchester Airport, we are committed to being one of the leading European airports when it comes to environmental management.
“As an organisation we recognise that climate change is an important global challenge. This achievement demonstrates the lengths we go to ensuring we balance our role as economic generator, alongside caring for the environment.”
Nice Airport in France has also become carbon neutral.
