One of the other things the Bill does is take forward measures to widen and deepen the devolution agenda by making it easier to set up new combined authorities, for authorities to join them and for them to gain new powers. How would you like to see the devolution agenda drive positive environmental outcomes? Is it primarily through helping towards our transport mission and better public transport? Is it through the housing quality mission? Or is it something else entirely? How do you think the devolution agenda can best serve a wider environmental agendaQ ? I put that to Carolyn first.
