Mr. Stewart Stevenson:

We are approximately two thirds of the way there at the moment. It varies from year to year. Last year, we had a 10% reduction. That was big, but it can be attributed to the very mild winter. God was helping us a little on that one. The areas that continue to be difficult are transport and property, as one might expect. We include in our numbers things that are not generally included elsewhere, such as aviation and shipping. There is no international requirement to include them. Incidentally, shipping is a much bigger issue than aviation when it comes to the emission of sulfur dioxide and particulates. Shipping is still running on 3% sulfur fuel, whereas aviation is moving away from such fuel and the rest of transport does not use it.
