No, we've not done it, but that's one of the reasons we partnered with Pollution Probe on this modest document. We have a very large concern that there has been a lot of emphasis over the past number of years--the planning period--on large final emitters, and that's fine. I know that under the previous government there was a process through which many of those large final emitters were in a very active dialogue with the government, but in our view the whole question of small and medium-sized businesses has not really been raised. Many SMEs don't even think of this as an issue that will impact them one way or the other.
