I think, from our research, we had exactly the same question. As an environmental organization, we want to look at it from an environmental perspective. Certainly if there's going to be no benefit to this, we don't want to be supporting it and seeing it being promoted as an environmental activity. So we did conduct our own research, and we have looked at the research of others. The large majority of the research says that there is a reduction in the life cycle of greenhouse gas emissions. I am aware of several studies that do not provide those same conclusions. For example, Dr. Pimentel is probably one of the more famous fellows who is not in favour of this. His research has been discredited by many. So at this point, as an environmental organization, we are fairly comfortable in the research that's out there and the research that we've done to say that there is a life cycle greenhouse gas benefit to this technology.
There are several environmental organizations in the United States that have taken the same approach and said we want to look at all the research and make sure we're actually promoting something that's good for the environment. They've come to the same conclusion as well.
