Air Pollutant - Nitrogen Dioxide
What this data shows
Published by National Environment Agency. 52 records. Fields include Year, Nitrogen Dioxide Mean (2 columns in total). Covers 2000-01-01 to 2025-12-31. Last updated 2026-04-01.
Description
National Environment Agency annual CSV of Singapore's nitrogen dioxide annual mean concentration from 2000 through 2025. Each row pairs a year with the NO2 mean, giving a compact long-run series of ambient nitrogen dioxide levels, a pollutant associated largely with vehicle exhaust, power generation, and industrial combustion. Environmental researchers and policy analysts use it to assess progress against air-quality targets and to relate NO2 trends to traffic growth and changes in the energy mix. The series also serves as background exposure data for public-health and epidemiological studies in Singapore.
