What data is expected?

Aggregate data about the emission of air pollutants especially those potentially harmful to human health (although it is not a requirement to include information on greenhouse gas emissions). Aggregate means national-level or available for at least three major cities. In order to satisfy the minimum requirements for this category, data must be available for the following pollutants and meet the following minimum criteria:

  • Particulate matter (PM) Levels
  • Sulphur oxides (SOx)
  • Nitrogen oxides (NOx)
  • Volatile organic compounds (VOCs)
  • Carbon monoxide (CO)
  • Updated on at least once a week.
  • Measured either at a national level by regions or at leasts in 3 big cities.

What data is available

  •   Openly licensed? No (No URL given)
  •   Is the data available for free? Yes
  •   Is the data machine readable? No (n/a)
  •   Available in bulk? No
  •   Is the data provided on a timely and up to date basis? Yes
  •   Publicly available? Yes(as trend Charts by Pollutants published by National Environment Agency)
  •   Is data in digital form? Yes
  •   Is the data available online? Yes (Here)
  •   Does the data exist? Yes


The URL does not lead directly to the data, it is required to manually locate the Air Pollution data (for instance via the site map). Pollutants data seems to only be available in simple html, and is therefore not machine readable nor available in bulk. Some entries (for instance Sulphur Dioxide SO2 Emission Inventory) show numbers from 2010, so not deemed up-to-date either. Data didn't change
