Footnotes:

  1. Emissions due to transport, other fuel combustion, and other sources.
  2. Percentage change since 1991.


Definitions & Technical notes:

Data on emissions of NOx are usually estimated according to international methodologies on the basis of national statistics on energy, industrial and agricultural production, waste management and land use, etc.

The most widely used methodologies are the 1996 Guidelines of the Intergovernmental Panel for Climate Change (IPCC) (see http://www.ipcc-nggip.iges.or.jp/public/gl/invs1.html) which is the basis for reporting to the UNFCCC. The latest revision and update of this guideline is 2006 IPCC Guidelines for National Greenhouse Gas Inventories (see http://www.ipcc-nggip.iges.or.jp/public/2006gl/index.htm). In earlier years the guidelines produced for the UNECE Convention on Long Range Transboundary Air Pollution were widely used in Europe, and are still used in some countries.

The main source for NOx is burning of fuels, particularly petroleum products. In some countries agriculture and burning of savannas is also an important contributor, but estimating these emissions is more difficult and often data are not available.

NOx emissions per capita is calculated by UNSD.


Data Quality:

Although standardised methods for calculating NOx emissions have been available for many years, calculating emissions of NOx is more difficult than for SO2, as many more parameters need to be taken into account. Therefore the quality of data on NOx emissions is considered to be only fair.
