Amsterdam, Netherlands Air Quality & Smog

Dominant pollutants, when pollution and smog are worst, a notable historical episode, and the official monitoring agencies for Amsterdam, Netherlands — plus how to check the current reading. Amsterdam reports air quality on the European Air Quality Index — our full guide explains how that scale works and how it compares to the US AQI.

Dominant pollutants

Nitrogen dioxide (NO₂, traffic), PM2.5.

Seasonal pattern: when smog is worst

Amsterdam's air is moderate. Traffic NO₂ is the main inner-city pressure, while PM2.5 has a notable secondary component formed from ammonia emitted by the Netherlands' intensive agriculture, plus contributions from port and industrial activity. The city operates a low-emission "milieuzone."

A notable air-quality episode

The Netherlands' nationwide nitrogen (ammonia + NOₓ) problem has been a major policy and legal issue, with court rulings forcing emissions cuts that affect farming, construction, and traffic across the country.

The local index and who runs it

Amsterdam reports air quality using the European Air Quality Index, not the US AQI — so the same air can read as a different number than you may be used to. The Dutch RIVM publishes the national air-quality index and station data; the EEA aggregates the Netherlands into the common European Air Quality Index.

• RIVM (National Institute for Public Health and the Environment)
• European Environment Agency (EEA)
