Glasgow Airport saved £11,000 in energy costs by implementing new efficiency measures in the last year.
It installed LED lighting, improved air conditioning systems and installed energy efficient vending machines, which resulted in more than 730 tonnes of annual carbon savings.
The airport also introduced a new terminal recycling system, which together with staff awareness training, helped save more than £8,000 a year.
An action group was formed last year which included retailers at the airport such as Boots, JD Weatherspoons and World Duty Free.
The airport worked with the businesses to ensure they followed new waste rules.
Commercial Manager Vicky McDowell said: “The charter was a joint agreement involving behavioural change, operational change and KPI [Key Performance Indicator] improvements. All 600 retail staff from over 30 businesses were trained in how to deliver the charter and we are delighted with the improvements we have seen so far.”
The savings follow the so-called ‘Resource Efficiency Pledge’ made by the airport in March last year. It is Zero Waste Scotland’s initiative which encourages businesses to commit to reducing their impact on the environment by making better use of energy, water and raw materials.
