The point I'd really want to make with regard to greenhouse gas emissions is that TransCanada is committed to doing its part to reduce greenhouse gas emissions. We are, in so doing, addressing the global issue of climate change. Our belief is that the solution lies both in terms of environmental performance, but as well in terms of using technology. Each year we do more to reduce our own emissions. We develop, together with our peers in the industry, technologies that can be brought to bear to achieve those reductions.
One of the specific examples would be this. We have quite an extensive program within our pipeline company to reduce what we call fugitive emissions, which are basically emissions from seals and things of that nature, to first of all, identify those and to take measures to reduce those. That's just one small example.
