That's a good question. I think the reductions we have seen with respect to methane regulations are real reductions, but what you're saying is that the absolute starting point may be different.
I think a lot of data out there would suggest that methane emissions are higher than we previously thought. That is why we have announced the methane centre of excellence, a body that is going to look at this. It will be independent of the industry. It will ensure that we have in place the appropriate methodology to measure.
