Thank you for the question.
It's not an area where we have active members of our association. It is an area where there's an awful lot of investment taking place, especially in the United States, but also in other parts of Canada.
The argument is that in the U.S. the use of more natural gas could help to significantly reduce the use of coal and therefore reduce their greenhouse gas emissions. That's why there have been such significant investments in the U.S. in this area; it's viewed as a way to reduce their overall carbon footprint. That would be the environmental argument around that.
