I rise to speak in support of amendment 124, tabled by my right hon. Friend the Member for Carshalton and Wallington (Tom Brake), and new clause 27, tabled by the hon. Member for Brighton, Pavilion (Caroline Lucas). I am very pleased that she is here to introduce it later on. What is the biggest long-term issue facing people here in Britain and across the world? It is not Brexit and it is not the world economy; it is climate change and the environment. For decades, we have thoughtlessly exploited our planet, heated the atmosphere and polluted the earth. The price we pay for continuing as before will be enormous. As part of the European Union, Britain is making progress to tackle climate change. Together, we have signed up to the Paris agreement. Many European laws and regulations, which are our laws, have been a force for good and have nudged the UK towards better environmental protection and better protection for human health. That was possible through the effective enforcement of those laws by EU agencies and the European Commission. The Bill carries with it the risk that we might scrap the commitments we have shared with the EU to go it alone, or to throw in our lot with America or another country. I want this country to become the greenest in the world. Before I became an MP, I was closely involved in improving how we dealt with our household and commercial waste following the EU landfill directive. Landfill produces a potent greenhouse gas, methane, and diverting landfill waste through recycling, composting and waste reduction is the only way to stop this greenhouse gas getting into the atmosphere. The UK is still one of the worst recyclers in the developed world, according to figures released the other day. We have a long way to go and would not have gone as far as we have without the EU pushing us in the right direction and the effective enforcement of the European enforcement agencies and the Commission. We have talked for a while today about how the UK has been a leader on particular EU legislation. That is the beauty of the EU: in some areas, we are leaders; in other areas, such as air pollution, other countries have been leaders. Together, we have produced a body of legislation that makes things better for us all. Another example of good EU legislation is how our beaches have been cleaned up following EU directives. British beaches are now 99% clean and safe-that is what the EU has done for us. The environment is owned by everybody. It is not a person or legal entity that can complain. Private ownership in a deregulated world does not protect the environment. That is why the legal principles that underpin the EU, as well as powerful and independent enforcement bodies, are so essential. Frankly, I am not reassured by Ministers. The recent Brexit impact assessment debacle or the war of words over regulatory alignment or divergence are prime examples of why we should not be bamboozled by fine words, but keep a watchful, eagle eye on the Government's every move. The draft animal welfare Bill that has been produced in a panic is not at all reassuring, but rather an example of how all the Government can do in the face of Brexit is to firefight. Indeed, the biggest problem for me is that Brexit has to happen in such an enormous rush, and that there is apparently the need to undo in a few short months the laws, regulations, enforcement, co-operation and partnerships that have evolved over 40 years. The protection of the environment depends on cross-border co-operation. The environment is not a game of politics. It is the one thing that can either guarantee or endanger our own survival. The next best thing to staying in the EU would be to stay in the single market and the customs union. That alone would protect the high standards for the environment, health, safe employment, consumer protection and animal rights, and the oversight and enforcement of those standards by independent agencies. That is why everybody in the House should support amendment 124, tabled by my right hon. Friend the Member for Carshalton and Wallington, which would ensure that the Bill's provisions would not undermine EU regulations and their enforcement during the transition period, while we are still operating in the single market. At the very least, we should set up independent regulatory bodies that are effective and have enough teeth to hold powerful organisations, global companies, industries and individuals to account, and new clause 27 would allow that to happen. Of course, it would be great if we could count on everybody to do the right thing, but experience tells us otherwise. Environmental crimes continue unfettered where there are not powerful laws and powerful enforcement agencies. Would it not be a tragedy if Brexit meant that we aligned ourselves with Trump's America, pulling out of the Paris climate change agreement, expanding our fossil fuel industry, undermining our renewable energy industry, trampling over environmental protection laws and sitting idly by as the planet warmed up? Climate change is not “Project Fearâ€; it is the worrying and brutal reality. I started by saying that climate change is the biggest challenge of our age-bigger than Brexit. What a tragedy it will be if the environment and vital action to tackle climate change are the biggest victims of Brexit.
