My Lords, I certainly share the right reverend Prelate's view that this matter will not become a reality unless we build from the bottom up and make sure that local groups, local initiatives, local business and local public authorities take on board the sustainability messages. That is an important dimension of what we see as the priorities for Johannesburg. For that to work properly a framework needs to be established by the heads of government. I am grateful for the right reverend Prelate's recognition of the role that the Prime Minister has played here. He was the first head of government to indicate that he would attend the summit.
