How far should Ontario’s emissions crackdown go?

by John G Smith

Cleaner air comes with a price tag. It’s paid every time equipment evolves in the name of controlling emissions. A tighter focus on particulate matter gave us diesel particulate filters. When regulators squeezed the allowable levels of NOx, we saw the widespread introduction of exhaust gas recirculation and diesel exhaust fluid. The current push to reduce greenhouse gas emissions has led to the rollout of everything from new oil categories to aerodynamic refinements and lighter components. Even battery-electric and hydrogen-electric trucks are now on the horizon.
