Climate Change Bill [HL]

My Lords, I reinforce what the Minister said about shipping. The International Maritime Organisation, which is responsible for all regulations regarding international shipping, has been urgently looking into the question of ship emissions. I spoke to the secretary-general last week, who told me that the work has been delayed for precisely the reason the Minster has just given: the complication of international shipping. I also remind the noble Lord, Lord May, that, although shipping may on the face of it be responsible for large amounts of emissions, he should remember that the vast bulk of international trade goes by sea. In fact, shipping per tonne mile is way more efficient than both lorries and aviation.
