Thank you, Madam Chair.
And thanks very much to our presenters. It's certainly been an interesting morning, in hearing the different aspects, as we have, from the different countries.
My questions, to start with, are going to be directed to Professor Rubin, please. It was very interesting to hear about the San Francisco experience. It's amazing that one city has passed the ordinance when the nation has not and when apparently others have not.
Have other jurisdictions looked at doing the same thing that San Francisco has done? Is this something that is catching on? That's one question.
I think you said at the end that there has been very little, if anything, done at this point. Have there been any improvements? Has this made a difference at all?
You also referred to some challenges that were apparent in the public works department. So I wondered if you would like to specify some of that and maybe just talk a bit more about those challenges.
