No, we haven't looked at an exemption, even though I know that some of our provincial colleagues have an exemption. I think Nova Scotia has been given an exemption to continue to use coal up until the 2030s.
I think we're going to work together and look at the existing system. We have about 25 communities that rely solely on diesel. We haven't found any economically feasible ways to get off diesel, although we've been holding public hearings on a new climate change policy for the Northwest Territories and a new energy strategy. We have some environmental groups that have come up with strategies that claim that within 23 years we can become 100% free of diesel, so we're looking at that.
I think this is going to require working closely with the federal government. We have asked for funding to convert to renewable and alternative forms of energy, to invest more in hydro, and to invest in road infrastructure that will reduce our greenhouse gas emissions.
