Clearly, various devolved responsibilities are involved in promoting renewables and in the work across a range of sectors to promote climate change measures. It is self-evident that global warming can be tackled only by nations working together, irrespective of national or international borders. It is therefore incumbent on all nations to do everything that they can to tackle climate change. I pay tribute to my hon. Friend for the work that he has done, especially with his private Member's Bill, to raise awareness of these matters, in this House and throughout Scotland.
