As you know, the fossil fuel area is a very active area economically. It contributes a lot directly to GDP. It's an area in which industy has to meet increasingly stringent regulations. Industry is investing a lot; it is also reorganizing itself a bit differently. The Canadian oil sands industry alliance is a good example of how industry is trying to mobilize itself to address some of the challenges it faces in environmental performance.
A number of companies have not only agreed to pool some funding for the research but to pool their IP as well. There are a large number of contracts being put in place, and actually some economists at Harvard are now looking at this model to see how well it is going to do in achieving environmental performance through pooling industrial funding. Because of the pressures now to do better as far as environmental impact goes, we see much more investment by the private sector, but also more innovative models for their ways of working together.
