Our experience is specific to the area of supermarkets. We're in the heat removal business. As part of the refrigeration process, we're rejecting heat from our stores, and generally it's rejected outside. We've worked with various developers on concepts where we would have a small district energy project where the heat we would be rejecting from our stores would be hosted in a larger development. That was one way we've looked at it.
We also look at the carbon intensity of the various regions where the electricity is consumed. We try to focus on those areas where we will see the greatest impact on carbon reductions as a result of the composition of the electricity generation supporting that region.
