We have a very active climate change working group, with respect to our own operations. Oil pipelines generally use electric pumps and therefore, in and of themselves are zero emitting. Natural gas pipelines use gas-fired compressors. We're looking for ways to run those more efficiently, and also to do waste heat recovery and other technologies.
I would just add, though, that on a global level, I personally do believe in climate change. I'm active personally on the board, for example, of the Climate Change and Emissions Management Corporation in Alberta, which is where the carbon levy funds $1.3 billion of technology projects.
I think in Canada we do need to recognize that from the oil sands, for example, we are producing just 0.15% of global emissions overall. The World Energy Council recently concluded its conference in Korea. I think that the closing statements from all global energy and environment leaders were very profound about the need to really address the global issues directly.
