My hon. Friend is making a fascinating speech—despite starting off talking about sheep, he has managed to keep everyone’s enthusiastic attention throughout. A lot of emissions-intensive British industries will already find it difficult to compete in the global marketplace. As we begin to encourage the use of carbon capture and clean hydrogen by heavy industry, they will face higher production costs. Would a border carbon adjustment enable heavy industry to decarbonise while preventing job losses, and is that something the Treasury would also find attractive?
