Malcolm can speak about it a bit more, but we've taken a staged approach.
For the real property plans, which are the plans you're talking about, we started with the departments that represent the overwhelming bulk of emissions, 81% of emissions. There were eight departments. Those plans are completed. The plan was that, in the greening 3 plan, which will be next year, we would move to have the additional 19 departments have their plans in place.
Because the methodologies had to be developed and approved, we've been phasing it in by starting with the departments that represent the most emissions and then proceeding to the other ones that can do that.
Malcolm, are there other things you want to add?
