I don't know that there are any specific elements. It's more the broader issue of the agenda around sustainability. We are being asked, as a biofuels industry, to take that issue very seriously from an economics, environmental, and social perspective. In doing so, we have suggested to a number of different forums, including the Canadian government, that looking at the issues around sustainability with respect to our industry by default implies that you would have to look at our feedstock sources as well. So when you look at a number of practices that have been put in place, which I alluded to in our presentation, Canada is a significant leader in that effort. We use lower amounts of inputs in our agriculture. In fertilizer inputs, for example, nitrogen content is clearly diminishing. We have no-till practices. The province of Quebec has fairly progressive agricultural practices with respect to where farmland is located, ensuring that you're not planting crops near open waterways and things like that.
Our members, our producers in Quebec, GreenField Ethanol and their Varennes project, in fact go beyond provincial standards and have established sustainability criteria practices, so that if you want to provide that feedstock to that ethanol plant, you have to meet a number of these additional conditions. So I think my suggestion is that we simply look at some of those models that we already have and expand them.
