I often tell the story of the chief executive who said to me during the passage of our zero carbon Act that his young daughter had told him one evening that she no longer wanted to have children, because of the climate crisis. He asked me, "What do I say to her?" Well, what I can say is that today, because of this bill, every organisation covered by the emissions trading scheme can start to play a greater part in making this world cleaner and safer, a world that I am sure that chief executive is hoping will one day be home to his grandchildren.
