I pay tribute to the hon. Lady and the Environmental Audit Committee. She knows that I and others are very impressed with the work she does. She raises an important point. The whole-of-Government approach is so valuable. We can no longer just point to a silo and say that if we have solved that, the problem is solved. We have to advance on all fronts. I will look at what she suggests we review. If improvement is needed, we will deliver it.
