Absolutely. I agree with the hon. Gentleman's very good point. We support new clause 67, which stands in the name of the Leader of the Opposition, which would protect environmental provisions. This is linked to a constituency concern that I have. Last week, I visited the Tarmac quarry at Cairneyhill, near Caldercruix in my constituency. It provides 30 good jobs and some of its staff have worked there for decades. Aggregate industry businesses such as Tarmac are energy and carbon-intensive, but they are working hard to reduce their carbon footprint as responsible operators. The EU emissions trading system has underpinned the UK's carbon reduction commitments for many years and provided a basis from which companies such as Tarmac operate. They need to know whether we will be in or out of the EU ETS. If we are out, what will the new rules be? Will they be linked to the EU ETS or to schemes such as the one in California? How will that be paid for? Who will police the rules? It is simply not good enough for the UK Government just to say, as they have so far, that this is subject to the negotiations, and here is why: businesses such as Tarmac make very long-term investment decisions that are based on their certainty of legislation and regulation. At my visit last week, we talked about Tarmac's plans for the Cairneyhill site 20 years down the line. It is not just for its own business's benefit that it does this; it is to protect the supply chain for infrastructure projects commissioned by Governments across these isles. Will the Minister guarantee that EU ETS allowances issued to UK operators for 2018 will be accepted for compliance purposes at the end of the EU ETS accounting year? Without such a guarantee, UK companies will face a bill that might run into millions. This uncertainty and lack of detail is concerning businesses and stakeholders across industry and civic life, especially with the ramping up of the Government's nonsensical no-deal rhetoric. We have before us a mess of a Bill, but that is little wonder given that, from the start of the process, the Government have made a mess of Brexit. From taking the electorate for granted before the referendum to assuming they did not need to plan for a leave vote, triggering article 50 before they were prepared, and calling a snap election to strengthen their position but in fact creating chaos, they have made a mess of Brexit. Our amendments would provide certainty in areas of confusion, confirming our existing rights and protecting them from those who wish to sweep them away, and would finally lift EU nationals living here from their tortuous limbo. We must give them protection and the lifeline assurance of the right to remain that the Government have disgracefully denied them. I commend amendment 70 to the Committee.
