The Dutch Clean Air Agreement is outperforming expectations. That deserves recognition — municipalities have worked hard on this for years. But those responsible for air quality policy know that the next challenge is already visible and more complex.
RIVM is clear: under the current adopted policy, the stricter 2030 European standards will not be met in many places. In Amsterdam, not a single monitoring station meets WHO advisory values for NO₂ and fine particulate matter. The downward trend is flattening. The time to adjust course is now, not four years from now.
From generic to place-based
The current particulate matter policy focuses on reducing total mass. This approach has delivered barely any health gains since 2015. TNO therefore advocates a different method: identify which sources produce the most harmful (ultra-)fine particles at each location, measure their composition, and link this to health outcomes. The sources in Rotterdam (shipping) differ fundamentally from those in Amsterdam (wood burning, traffic) or Eindhoven (agriculture). A policy that ignores these distinctions loses both effectiveness and public support.
Air quality is not good enough
This points to a broader challenge. Air quality is only one of the factors determining residents’ health. RIVM shows that 4.5% of the total health burden stems from an unhealthy living environment, with noise, lack of green space, and limited opportunities for physical activity weighing equally heavily. And climate change is further amplifying that burden: more heat stress, longer pollen seasons, and rising infectious diseases.
The opportunity lies in integrating policy for healthier urban environments. Greening neighborhoods reduces heat stress and encourages physical activity. Reducing through-traffic improves air quality, noise levels, and road safety simultaneously. Measures with double or triple health returns exist — but they require air quality, climate adaptation, and spatial planning to be programmed together, not alongside each other.
The full picture of a healthy living environment is the real assignment. Four months longer is a start. A healthy neighborhood for everyone is the goal.
