Well, actually, you raise an issue. There is, as you know quite well, an issue in the Greater Vancouver area, and particularly in Surrey and North Delta, with some changes we made in recent years to the approach and departure paths for Vancouver International Airport. Those changes, by the way, are right now saving the airlines $20 million a year in fuel and--I've forgotten the number--thousands of metric tonnes in greenhouse gas emissions. However, that has upset some residents who feel they weren't adequately consulted. They now are experiencing aircraft noise that they didn't before. So we listened to that. We made some changes to those patterns as a result of that.
The number of noise complaints we have received since we made those changes has dropped dramatically. The issue has not gone away, so we have funded noise monitoring stations in the areas, along with the YVR airport, which is also funding them. We've also recently put up an interactive website that shows all of the air traffic movements in real time in that area, and it identifies the flights and has a process for people. If they are bothered by a flight, they can identify specifically which one it is because they can replay the tape and right on the exact time.
However, on noise monitoring, we have not had any incidents yet where any aircraft, other than I think on one or two rare occasions, actually penetrated the internationally accepted levels of noise, as being more than just the urban background noise. We've certainly detected lots of other noise events that are not aviation related.
Having said all that, there are still people with a lot of concerns. We're continuing to meet with those groups, with the various municipal councils. I'll take your invitation for July 9 under advisement. We'll see if we can send somebody there. We are sensitive to them. We've also committed that in future we will do more consultation ahead of time with various communities if we feel there are going to be any adverse effects.
