The carbon price floor was introduced by this Government—or, rather, this Government when they were in coalition. The point is not to deny that transition needs to take place; the point is we have to do it in the right way, and I do not disagree with that.
I now wish to carry on making my case. If we support zero emissions globally—that is what the Secretary of State has done—the logical position is that we must also support it domestically. We set a target of an 80% reduction, but it does not make sense to have 80% as the target when we know from the science and from the global agreement that we will eventually have to get to zero emissions.
The second part of my case is based on economics, and I wish to make the following comments to Conservative Members in particular. They will worry that my proposal sounds as though it is going to raise costs, but quite the opposite is true. I ask them to listen to some of the business voices who are saying that they want us to set a clear target for zero emissions. Why are they saying this? It is because certainty is the friend of business in this area and uncertainty its enemy. Richard Branson has said that a net zero emissions goal simply makes “good business” as it
“will drive innovation, grow jobs, build prosperity”.
He is joined by many other business leaders in making that case. Just as it is the right thing to do for business, so, too, is it the right thing for government. We are
going to have to make decisions on infrastructure now which will have implications for 20, 30, 40 years hence. It is right to make those decisions on the basis of what we will eventually have to achieve, albeit in the second half of the century, because we know that we will have to get there.
Thirdly, and finally, my case goes beyond our borders. The Paris agreement is a great one, but its biggest weakness is that if we look at the aggregate of the different commitments made by different countries, we see that although the aspiration may be to limit warming to less than 1.5°, when we add them up they seem to be more like 3°-worth of commitments. Some might ask what difference the UK can make, as it represents only 1% of global emissions. They might ask why our acting has an impact. I say to the House that it does have an impact. The Climate Change Act—I give credit to the Conservative party because it supported this and actually pushed the then Government to do this—had an impact, not only in Britain but around the world. When the Secretary of State went to the Paris negotiations and urged others to take action, they were not able to say to her, “You are pretending you care about these things and want to legislate for them, but actually you are not taking action in your own domestic legislation.” We did do that.
