Interim Plan 2001 on Particulate Matter and Ozone: chapter 2
2.0 Emissions
The basis of this Interim Plan 2001 on Particulate Matter and Ozone is a series of actions aimed at emission sources with the greatest impact on air quality. Transboundary pollution, and the transportation and industrial sectors, are the major sources. The table below shows the importance of addressing emissions in the transportation and industrial sectors.
