Notes and Sources
Notes: Historic data may be revised annually. SOX= Sulphur oxide. NOX= Nitrogen oxide. PM2.5= Particulate matter less than or equal to 2.5 microns. VOC= Volatile organic compounds. CO= Carbon monoxide.
Description:
Table EN5 outlines air pollutant emissions from the transportation sector from 2005 to 2023, showing a significant overall decline across pollutants such as SOX, NOX, PM2.5, VOC, and CO. Notably, sulfur oxides (SOX) saw the steepest reduction over this time falling by 96%, followed by VOC at 71%, PM2.5 at 65%, NOX at 63%, and CO at 59%.
Methodology:
The data were taken directly from the original data source.
