How do Scottish local authorities under COSLA perform against air quality targets compared to other UK regions?
Every single local authority in Scotland's COSLA network meets air quality targets that exceed WHO standards, a performance distinctly ahead of most UK regions. This success stems from a coordinated national approach where Scottish authorities actively share best practices across different cities and communities.
A collaborative framework that works across Scotland
The Community of Local Authorities Scotland (COSLA) operates as a unified system where air quality compliance is measured against internal standards more stringent than international WHO benchmarks. This creates a performance floor significantly higher than the legal minimum required under UK legislation.
What distinguishes Scotland's approach, as detailed in the episode with Kate Barnard, is the recognition that uniform solutions do not translate across different geographies. Each Scottish city and region faces distinct air quality challenges shaped by local traffic patterns, geography, and economic activity.
Knowledge sharing as a competitive advantage
Rather than competing or working in isolation, Scottish local authorities function as a coordinated national team that openly shares what works. This peer-to-peer learning accelerates problem-solving: a solution proven effective in one city becomes a reference point for others facing similar challenges.
By contrast, many UK local authorities struggle with compliance. In fact, as Kate Barnard explains in The Responsible Finance Podcast, UK local authorities have a legal requirement to document and demonstrate their air quality performance—yet a surprisingly high number fail to meet even mandatory standards.
"The local authorities in the UK have a legal legislative requirement to document and provide evidence of their air quality and it is quite surprising how many do not meet it."

According to research commissioned by Enjoy the Air through Yonder polling of 4,000 people across the UK, 48% of 18 to 24-year-olds would move to a city or place with better air quality.
Key takeaways
- All COSLA local authorities in Scotland meet air quality targets stricter than WHO standards, demonstrating nationwide compliance at a higher threshold than mandatory UK requirements.
- Scotland's coordinated approach enables active sharing of best practices between authorities, recognizing that solutions must be tailored to each region's unique geography and circumstances.
- Many UK local authorities outside Scotland fail to meet even legal compliance documentation requirements, despite statutory obligations to prove air quality performance.
- Peer-to-peer knowledge transfer within COSLA accelerates the adoption of proven interventions across different cities and communities.
