Reducing smog emissions is a key part of our Anti-Smog Action Plan. The plan unites more than 50 partners in a joint effort to reduce smog-causing emissions in Ontario by 45 per cent of 1990 levels by 2015. There is also a particulate strategy, with an interim reduction of at least 1 per cent in emissions contributing to fine particulate matter. We've also pressed the smog issue with our American neighbours, who account for 50 per cent or more of the emissions that cause our smog. We went to court in support of the U.S. Environmental Protection Agency's efforts to reduce the transboundary movement of ground level ozone and nitrogen oxides from several U.S. states.
Climate change is another issue that respects no borders.
Ontario is a leader in its efforts to address the issue. Many of our programs have side-benefits that are helping in this respect. For example, a year of Drive Clean has led to an estimated reduction of 18,500 tonnes in emissions of carbon dioxide, a key contributor to climate change. Again, this was accomplished with less than a third of the vehicles to be covered by Drive Clean. Greater reductions will be realized as the program expands.
