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


Additional data can be easily accessed through the Energy community at The primary datasets with this material are the Toxic Release Inventory, but other datasets provide insight to additional environmental pollutants. Air pollution data exists at the given link. As the data is provided from federal websites and is therefore public domain (at least in the US) we consider it openly licensed.

There was no terms of use of license related to these data, however these are presumed to be in the public domain as is common for these federal agengies. A tweet was sent. The URL provided was for the entire EPA site which did not point to TOU.

I Updated the file formats as there are many more.

Reviewer comments

I could not find information regarding licencing, I can presume the public domain but could not find evidence of that, also, I updated the file formats.
