I don't have access to studies of that nature. However, I would point out that in the last figures I saw in Canada, the forest products industry is one of the only industrial sectors, if not the only sector, that has met what in the past would have been Kyoto targets. The last number I saw was about 28% below those targets in 1990. We've done an excellent job of beating the greenhouse gases.
Unfortunately, a big part of that is because of the curtailments in operations and the shutdowns and certainly the application of new technologies and what not. I think it's very apparent, if you look at the figures, that the transportation industry, along with the electrical sector, has a significant impact on greenhouse gases and carbon emissions.
If you were to eliminate the opportunity of rail and had to go by truck, there would be a significant increase in greenhouse gases, mostly because there are a lot more diesel engines on the road moving the same amount of product. Rail is a very environmentally friendly option because of the ability to move large volumes with very low emission rates. It's the same with the seaway. Unfortunately, the seaway is only available to those people who have access to it and are relatively close. It doesn't do a lot of good for people in Saskatchewan and Manitoba unless they can get it to a port. I would suggest that is a key item you bring up.
