What is the annual mean PM2.5 concentration in Isle of Wight?

The population-weighted annual mean PM2.5 concentration in Isle of Wight is 5.58 µg/m3 (DEFRA Pollution Climate Mapping model, 2024). This is above the WHO 2021 annual guideline of 5 µg/m3 and below the UK 2028 interim target of 10 µg/m3.

What fraction of deaths in Isle of Wight are attributable to air pollution?

According to UKHSA Fingertips (indicator 93861, 2024), an estimated 4.2% of mortality in Isle of Wight is attributable to particulate air pollution. This figure, produced by OHID from DEFRA modelled data, forms the health-context component of the Gera Air Health Index.

How is the Gera Air Health Index calculated for Isle of Wight?

GAH = 0.6 × PM2.5_score + 0.4 × health_context_score. PM2.5_score is min-max normalised across all 296 LAs (4.20 µg/m3 = 10/10, 10.96 µg/m3 = 0/10); health_context_score is min-max normalised from UKHSA Fingertips mortality fractions (3.2% = 10/10, 8.1% = 0/10). Full methodology at /methodology/gera-air-health-index.

Is the air quality in Isle of Wight getting better or worse?

The 2024 figures reflect the most recent DEFRA PCM modelled annual mean. UK PM2.5 concentrations have fallen substantially since 2010 due to emission reductions, but remain above the WHO 2021 annual guideline of 5 µg/m3 in most English local authorities. Isle of Wight (5.58 µg/m3) is working towards the WHO guideline. Gera updates GAH annually when DEFRA publishes new PCM data.
