Air quality in Campo de Ourique, Lisboa

No modelled values here

Campo de Ourique falls outside the domain of the 1 km European air quality maps, which stop at the European mainland. There is no modelled annual value and therefore no rating for anywhere in this freguesia. That is a gap in the data, not a statement that the air is good or bad.

Thirty Portuguese municipalities — all of them in the Azores and Madeira — are in this position.

What the monitors near Campo de Ourique have measured

These are real measurements from the nearest official monitoring stations. A station a few kilometres away can differ a lot from a specific street, especially for nitrogen dioxide, which falls off sharply away from traffic.

Fine particles under 2.5 micrometres (PM2.5)

Coarse particles under 10 micrometres (PM10)

Nitrogen dioxide (NO₂)

Ozone (O₃)

This is the annual mean of the hourly ozone measurements. The EU target value of 120 µg/m³ is written against a different statistic — the daily maximum 8-hour mean — so it is not drawn here. Ozone behaves unlike the others: it is destroyed by fresh traffic exhaust, so a busy street often reads lower than the countryside around it.

The stations these come from

A traffic station sits beside a busy road and reads the worst case; a background station reads what the area as a whole breathes; an industrial one sits near a plant. Which kind you are looking at matters more than the distance.

MEASURED — hourly observations reported by Portugal to the European Environment Agency, aggregated here into annual means. Years with less than 50% valid hours are left off the chart. Station names and locations come from APA's QualAr register; station type and setting from the EEA's station metadata. Verified data through 2025; the most recent year is provisional and not yet verified.

This is a hand-curated list with sources, not a forecast and not a model. We have not estimated how much any of these would change the air. The list is small and certainly incomplete: it holds 15 entries for the whole country. Anything genuinely local — a quarry, a new estate road, a planning application — will not be here, and a buyer should still ask the council.

• Metro de Lisboa — Linha Circular (Rato–Cais do Sodré, estações Estrela e Santos)
  rail · under construction · likely effect on air: better

  888 m
  south-east

  Two new metro stations and a new link between the Yellow and Green lines give central Lisbon another alternative to driving, and the surrounding streets should carry less car traffic once it opens.

• Zona de Emissões Reduzidas de Lisboa (Zona 1 Avenida/Baixa, Zona 2)
  low emission zone · operating · likely effect on air: better

  1.6 km
  north-east

  Cars that do not meet the Euro standard set for the zone need council authorisation to drive in the Avenida da Liberdade and Baixa axis and in a wider surrounding zone, which keeps the oldest and dirtiest vehicles out of central Lisbon.

  low emission zone · proposed · likely effect on air: better

  1.6 km
  north-east

  A much stricter low-emission zone for the Avenida, Baixa and Chiado was recommended to the city council by the municipal assembly and has not been implemented, so it is a possibility for the area rather than a rule in force.

• SN Seixal — Siderurgia Nacional, Paio Pires (Seixal)

  12 km
  south-east

  A steel plant operates at Paio Pires and has been the subject of long-running complaints and court proceedings about its emissions, in which the court found it complies with its environmental licence.

  The waste-to-energy plant that burns municipal waste for Lisboa, Loures, Amadora and Vila Franca de Xira runs at São João da Talha under an environment agency permit, so it is a permanent permitted stack in the lower Tagus corridor.

Sources and what they cannot tell you

• Measured history — European Environment Agency Air Quality Download Service: 19,038,066 validated hourly observations from Portugal's 71 stations, 2013–2026. Station names from APA QualAr. A station is not your street. Nitrogen dioxide in particular varies by hundreds of per cent over a few hundred metres.
• Modelled values at the address — the EEA / ETC-HE 1 km European air quality maps, 2024 and the three years before it. A 1 km cell is an average over a square kilometre. It cannot see one side of a street being busier than the other, and it will understate a very local source and overstate a very local clean spot.
• Industry — European Industrial Emissions Portal, reporting year 2024, as declared by operators. Only installations above the European reporting thresholds appear. Emissions reported are annual totals: they say nothing about when, or which way the wind was blowing.
• Roads — OpenStreetMap, © OpenStreetMap contributors (ODbL). Distance to a road class, not to traffic. A quiet primary road and a jammed one look identical here.
• Boundaries — CAOP (Carta Administrativa Oficial de Portugal, DGT), all 308 concelhos and the freguesias of the Lisbon and Porto metropolitan areas.
• Known projects — curated by hand, each with a citation. Not a forecast. Incomplete by construction.
• Address lookup — OpenStreetMap Nominatim. A geocoder returns the coordinate it thinks you meant. Check the place name we echo back before trusting the figures.
• Not used — CAMS reanalysis, which would give hourly modelled history, needs a Copernicus Atmosphere Data Store key that this build does not have. Madeira and the Azores fall outside the 1 km European map domain, so those 30 municipalities have measured station data but no modelled values and no rating.
