Air quality across Argyll and Bute remains ‘consistently good’

Air quality across Argyll and Bute has remained consistently high, with pollution levels well below national limits, according to a newly published council report.
The 2025 Local Air Quality Annual Progress Report shows that all monitored pollutants met required standards throughout the year, with no need to designate any Local Air Quality Management Areas.
Figures from the council’s Environmental Health service also reveal that nitrogen dioxide (NO₂) levels, closely linked to road traffic, have fallen significantly in some of the area’s busiest towns. In Oban and Helensburgh, concentrations have dropped by an average of 51 per cent over the past decade.
Officials say the improvement is likely due to advances in vehicle technology and a growing number of electric and hybrid cars on the roads.
The report highlights the wider importance of clean air, not only for tackling climate change but also for protecting public health, particularly among vulnerable groups such as children, older people and those with existing medical conditions.
Looking ahead, Argyll and Bute Council is preparing to strengthen its approach to maintaining air quality standards. Plans include setting up a new multi-service working group, reviewing planning processes to ensure air quality remains a key consideration in future developments, and creating a new Local Air Quality Strategy aligned with national policy.
Councillor Gordon Blair, policy lead for planning and regulatory services, welcomed the findings.
He said: I am heartened to hear that our air quality continues to remain good and that we are moving to ensure it stays that way. It’s important for the health and wellbeing of our communities, and for the economy that is boosted by visitors who come to enjoy air that is often bracing, but always fresh.
The council will continue to carry out annual monitoring to track long-term trends and ensure standards are maintained.
