Thank you very much, Chair.
I'd like to follow up on the comments made by Mr. Harris and Mr. Cullen with regard to the effectiveness of the program and how we measure success. I think we've spent, according to your numbers, $960 million over four years for these programs, and the overall objective is how much we reduce gases by.
You mentioned, Mr. Corey, that you would love to spend a lot more money if it were available. Obviously we have limited resources, so it does boil down to value for money. In your opinion, are we getting the optimal value for money for the investments we're making to reduce the greenhouse gases?
