Clean air is a human right. Air pollution causes 8.1 million premature deaths every year, making it the second leading risk factor for death globally ahead of smoking and poor diet.
State of Global Air, 2024
Urbanisation and ecosystem degradation have deepened the crisis, but nature – from forests to urban green spaces – holds the key to cleaner air, healthier communities and climate resistance.
With new regulations in Europe and Belgium expanding accountability for air quality from 2027 – covering offices, schools, restaurants, public areas and beyond – the pressure to act is building.
Clean air isn’t a luxury. It’s the baseline condition for a livable environment – and the data from forests and cities tells us exactly how far we’ve drifted from it.
WHAT
ForestScan compares air quality between forests and cities in real time.
ForestScan is an open-sourced dashboard by Airscan.org and GoForest.be. We compare real-time air quality data between forests and cities to reveal the contrast between our environments with one fundamental difference – the presence of human activity.
Reveal
The stark contrast in air purity between forest and urban environments.
Educate
How ecosystems act as natural air purifiers and carbon sinks.
Advocate
For policies that protect nature and expand green space in and around cities.
