All right.
What you're proposing is a very interesting step toward reducing greenhouse gas emissions. The government will have to want to head in that direction. However, that's not what we're currently seeing. The only person who thought it was important to reduce greenhouse gas emissions was expelled from the Conservative caucus yesterday. That's quite revealing.
The current strategy is to try to confuse the public by associating the fight against smog with global warming. And yet, from what I understand, you can fight smog by filtering emissions and particles that contribute to smog without reducing greenhouse gas emissions, since CO2 would be filtered. The reverse would be more effective, that is to say to reduce greenhouse gas emissions by lowering our fuel use at source, which would have the effect of reducing smog.
Do I have a good understanding of the problem?
