“When Canada and the United States signed the Air Quality Agreement in 1991, transboundary movement of air pollution from industrial activities on both sides of border resulted in acid rain causing serious damage to our environment and in smog posing a serious threat in the air we breathe. After twenty years of cooperation, emissions causing acid rain have been cut in half and emissions causing smog have been cut by one-third in the region covered under this agreement,” said Minister Kent.
In Canada, emissions of the key pollutants that contribute to smog, acid rain and poor air quality have seen significant declines since 1990. Emissions of sulfur oxides (SOx) declined by about 54%, mainly due to reductions from base metal smelters which were down 72% and fossil fuel-fired electricity generating utilities which decreased by 45%.
Regulators such as OSHA, ABSA and other authorities and code committees such as API, ISO, ISA, and FSA have come up with industry codes by showing an active participation along with manufacturers to reduce emissions.
