Climate Change Bill [HL]

What happens then if some of these parts come in from overseas? How and at what stage is it recorded, and who has to keep records? It seems an absolute nightmare. In principle, the idea is good. Most of us around the Chamber would agree that it is sensible, but I can see this paper trail going everywhere. If you are looking at component parts that come into this country which are then put together or manufactured here, where does the buck start and how does it get passed back to the relevant authorities?
