Methane is probably one where we could have the biggest impact, given that the sheer impact of every methane emission, by a factor of 28 compared to CO2s, and we're still a large and significant emitter. The government has made significant commitments to reduce it, and we feel that quite a few of the technologies available out there could be applied right now. We've clearly put this as a top priority, and the provinces are working with us and the industry, recognizing that this is something we could do in fairly short order that would have significant impact at a macro level.
