Thank you very much, Madam Chair.
Thank you to the witnesses for being here.
It's a pleasure to see you again, Ms. Brouillette. I want to touch on the letter that the Climate Action Network jointly signed to the Prime Minister earlier this year, in March.
The industrial carbon pricing is “widely agreed to be the most efficient road to industrial decarbonization”. Can you explain to the committee what is meant by “efficient”?
