NHS Grampian has saved more than £4.5 million in medical costs due to falling emissions in the north-east.
According to new figures released by the Office for National Statistics (ONS), the health board has saved £4,524,437 in health costs due to a reduction in emissions.
The statistics also show that woodlands, grasslands and shrubs in the north-east absorbed 36,400kg of pollutants in 2015.
The figures form part of a £1 billion saving for the NHS across the UK, which means an estimated 7,100 fewer heart and lung-related admissions to hospitals, 27,000 life years saved and 1,900 fewer premature deaths.
A spokesman for NHS Grampian said: “The health benefits of clean, fresh air are well documented and in the north-east we are fortunate to have one of the country’s finest national parks on our doorstep.
“Woodlands, grasslands and shrubs in Aberdeenshire and Aberdeen absorbed an estimated 36 tonnes of air pollutants and around 80% of that was potentially harmful ground-level ozone.
“That has a multitude of benefits upon health and wellbeing in our area which should not be underestimated.
“We also recognise the importance of green space in helping to reduce air pollution which is one of the major reasons we are investing in a multi-million-pound project to improve the green areas across the Foresterhill Health Campus over the next few years.”
Gregor McAbery, spokesman for Friends of the Earth Aberdeen, said: “There can be no doubt that measures that reduce air pollution will mean reduced health costs in the long run and better quality of life for residents and patients.
“That is why more must be done to encourage active travel and bus use where possible.
“Clearly this summer’s extreme weather is an urgent reminder that we need to continue making the changes needed to tackle climate-changing emissions.”
