Why is the program ending?
Air quality in Washington is much cleaner than when the program began in 1982, and every community in our state currently meets all federal air quality standards. The combination of the testing program, advances in vehicle technology, and improved motor fuels have led to significant reductions in transportation-related air pollution.
In 2005, the Legislature passed a plan to phase out emission testing based on Ecology’s projection that we would no longer need the program by 2020 (RCW 70.120.170). Despite the end of mandatory emission testing, we believe air quality will continue to improve in the years ahead as newer, cleaner vehicles replace older, less-efficient models.
Even after the emission check program ends, Ecology and our local clean air agency partners will continue to monitor, protect, and improve air quality. We are also continuing to work to reduce greenhouse gas emissions from motor vehicles - the largest source of carbon pollution in Washington.
