Everyone makes their contribution in their own way. The point that my hon. Friend makes is right in this sense: if we are to tackle climate change, it is essential that we get international agreement. It is worth pointing out to the House that, as a result of the growth being experienced by China, we estimate that even if we shut down all the emissions in this country, it would take the Chinese economy about 12 months to make up the difference. Of course, we must continue our leadership role on the issue. That is why we will more than meet—indeed, we will double—our Kyoto targets. It is important that we take measures in the United Kingdom, but there is no serious answer to climate change except at an international level.
