Ozone Annex to the Air Quality Agreement Document type Bilateral Field of application Regional/restricted Date Dec 7, 2000 Source FAO, FAOLEX; IUCN (ID: TRE-160041) Place of adoption Washington Language English, French Entry into force Dec 7, 2000 Subject Air & atmosphere Keyword Long-range air pollution Public participation Public health Ozone layer Renewable energy Transboundary effects Emissions trading Emissions Air quality/air pollution Research Monitoring Geographical area North America Abstract The Ozone Annex was added to the Canada-United States Air Quality Agreement (December 2000) to address the transboundary air pollution leading to high air quality levels of ground-level ozone, a major component of smog. The long-term goal of the Ozone Annex is the attainment of the ozone air quality standards in both countries. Where there are transboundary flows of the pollution that creates ozone, the Ozone Annex commits both countries to reduce their emissions of nitrogen oxides and volatile organic compounds, the precursor pollutants to ground-level ozone.
