📡 Brighton's 50-Sensor Network & Major Improvements
1. 50 Real-Time Sensors Deployed Oct 2024 (Sussex Portal)
Network: 50-sensor deployment providing comprehensive city coverage
Brighton deployed 50 real-time air quality sensors in October 2024 as part of the Sussex Portal monitoring system - one of the UK's largest urban air quality networks. The sensors provide continuous PM2.5, NO2, and other pollutant measurements with hourly updates. This unprecedented monitoring granularity enables precise identification of pollution hotspots, rapid intervention, and evidence-based policy decisions. The Sussex Portal makes data publicly accessible for residents.
2. Vogue Gyratory 54→37 µg/m³ (17 µg/m³ Improvement)
Success: 31% NO2 reduction at major traffic junction
Vogue Gyratory achieved a remarkable improvement from 54 µg/m³ to 37 µg/m³ NO2 - a 17 µg/m³ reduction representing 31% improvement. This major traffic junction was previously Brighton's worst pollution hotspot, exceeding the 40 µg/m³ legal limit by 35%. Now below the limit for the first time, the improvement demonstrates how targeted traffic management, cleaner vehicles, and junction optimization can dramatically reduce pollution at critical locations.
3. Lewes Road 40→28 µg/m³ (12 µg/m³ Drop)
Improvement: 30% NO2 reduction on major arterial route
Lewes Road dropped from 40 µg/m³ to 28 µg/m³ NO2 - a 12 µg/m³ reduction (30% improvement). Previously right at the legal limit, Lewes Road now has comfortable compliance margin. The major arterial route carries heavy traffic but benefited from bus fleet improvements, traffic flow optimization, and the city's air quality interventions. The 28 µg/m³ level is one of Brighton's best outcomes for a major route.
4. Hollingdean Road 35→19 µg/m³ (16 µg/m³)
Achievement: 46% NO2 reduction - Brighton's best improvement
Hollingdean Road achieved Brighton's most impressive improvement: 35→19 µg/m³ NO2 - a 16 µg/m³ reduction representing 46% improvement. This nearly halves the NO2 level, bringing it well below the 40 µg/m³ limit and approaching the WHO's 20 µg/m³ interim guideline. The dramatic improvement demonstrates how residential street interventions can achieve exceptional results through traffic calming, vehicle restrictions, and local measures.
5. WHO Interim Targets 2026
Ambition: Targeting WHO interim guidelines by 2026
Brighton is targeting WHO interim air quality guidelines by 2026 - stricter standards than UK legal minimums. Current PM2.5 levels of 6-11 µg/m³ are close to WHO's 5 µg/m³ annual guideline. NO2 improvements (Vogue Gyratory 54→37, Lewes Road 40→28, Hollingdean Road 35→19) position Brighton well for WHO interim targets. The 50-sensor network (Oct 2024) enables precise tracking toward these ambitious health-protective standards.

🏠 Protect Your Health: Indoor Air Quality Solutions
While Brighton achieved excellent improvements (Vogue Gyratory 54→37 µg/m³, Lewes Road 40→28 µg/m³), the 50-sensor network shows localized hotspots remain. Check Sussex Portal data before opening windows.
Recommended Solutions
- MERV13-16 Air Purifiers: Remove 85-95% of PM2.5 and NO2 pollutants. Target 5-6 air changes per hour (ACH) in bedrooms and living rooms.
- DIY Corsi-Rosenthal Box: Cost-effective solution at £150-200 using filters from B&Q or Screwfix. Excellent for coastal city pollution protection.
- Use Sussex Portal Data: Brighton's 50-sensor network (Oct 2024) provides real-time pollution data. Check your local sensor before ventilating - only open windows when outdoor pollution is low.
- Targeted Protection: Essential near Vogue Gyratory (now 37 µg/m³, was 54), major routes, and localized hotspots identified by the 50-sensor network.
💨 Why Indoor Air Filtration Matters in Brighton
Brighton's dramatic improvements (Vogue Gyratory 31% drop, Lewes Road 30%, Hollingdean Road 46%) demonstrate excellent progress. However, PM2.5 levels of 6-11 µg/m³ still exceed WHO's 5 µg/m³ guideline. The 50-sensor network shows micro-level variations - indoor filtration provides consistent protection regardless of hyperlocal outdoor fluctuations, especially important near traffic routes and during high pollution episodes.
