u.s.–canada air quality agreement
in recent years, the canada-united states air quality agreement, signed on 13 march 1991, has improved air quality by reducing sulfur dioxide and nitrogen oxide emissions in both countries. the agreement was meant to address the issue of transnational air pollution between the two countries. the agreement was expanded in 2000 to also include goals of reducing emissions of volatile organic compounds and levels of ground-level ozone. ground-level ozone is caused by reactions between nitrogen oxides and vocs in the presence of sunlight. ozone is a contributor to smog and is known to cause numerous respiratory diseases. the 2012 canada-united states air quality agreement progress report found that "canada's total emissions of sulfur dioxide have decreased by 57% from 1990 levels while the u.s. has reduced total sulfur dioxide emissions from covered sources by 67% from their 1990 emission levels. between 2000 and 2010, canada reduced total emissions of nitrogen oxides by 40% in the transboundary ozone region while u.s. total nitrogen oxide emissions decreased by 42% in the region".
