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.

Data Location


The data is not the official. The Official data should be on National Oil Spill Detection and Response Agency(NOSDRA) but presently they do not have a data portal.

In 2014, NOSDRA released a map data of oil spills in the country at however, overall pollutants emission monitoring is the responsibility of NESREA (National Environmental Standards & Regulation Enforcement Agency) which has its website at , unfortunately, it does not have a data portal

Reviewer comments

The official government website does not have the required data. Most data for this needs to be available in bulk.
