It is a pleasure to follow the hon. Member for Weaver Vale (Mike Amesbury), but I have a different view from his. It is worth remembering that this country has reduced its carbon emissions very substantially over the last decade—twice as fast, in fact, as the European Union. It is worth remembering that when we say that we are not making progress. There is an awful lot to do, as we have heard, and we cannot rule out any options, so legislating against a particular technology is not where the Government should be. We have to be technology-neutral. Frankly, we will need all options if we are to get to net zero; we cannot simply rule out one or the other.
We will have houses heated in one way and others in another way; we in this House cannot simply take the decision to blanket refuse a particular approach.
There are things that we should encourage. Frankly, I cannot see why we do not put in place robust rules on building solar into every new building—particularly every new commercial building. We can do things that do not close options but take us a step down the road. The Government should be taking such measures, but they probably fall into the pot of the Department for Levelling Up, Housing and Communities rather than that of the Department for Energy Security and Net Zero.
I will focus in particular on an area of energy that has been touched upon only briefly in an intervention: the whole issue of aviation fuel. If we are to achieve net zero, we need an aviation industry that also moves rapidly towards net zero, and that is not an easy task. It is a particularly difficult task for the aviation sector because the technology is not yet there to make significant progress in that direction. But it is getting there, and we have to do what we can to encourage it, because the aviation sector is hugely important to this country. Both sides of the House have agreed in the past that its importance needs to be supported and protected. That was noted in particular when we voted on the expansion of Heathrow airport: the vast majority of Members supported the industry on that night. We have to continue doing so while accepting that the industry has to transform itself. It cannot simply stand outside the plans to deliver net zero; it has to change.
The industry will change—insofar as we can currently see the technological routes—in two different ways. First, hydrogen will play an important part in the future of the aviation industry. The first very short-haul 19-seater passenger planes with hydrogen technology powering them are already being tested, and that is a positive step forward. There will be some electrification of aircraft, but only at the smallest end of the scale. Given the way in which technology is developing, it is realistic to assume that, by the middle of the 2030s, we will start seeing short-haul passenger aircraft—the A320s and A319s, or their equivalents and successors—powered by hydrogen. However, there is very little prospect any time soon of long-haul aircraft being powered by hydrogen or electricity. We will not abandon travel around the world. That would be disastrous, not just economically but for a whole raft of reasons. If we took away long-haul aviation, serious damage would be done to conservation efforts around the world, for example.
We will need what is called sustainable aviation fuel. The benefit of that fuel is that it can, to a significant degree, be produced from waste. By waste, I do not just mean more biowaste; I actually mean municipal waste. Some of the early projects to create sustainable aviation fuel have used municipal waste—black binbag waste from people’s homes. That is a huge opportunity, but we have to support the development of that industry. We live in a world that is increasingly shaped by what is happening in North America, including the United States’ Inflation Reduction Act—a slightly strangely named piece of legislation if ever there was one—and what will now happen in the European Union as a result. I am a strong free marketeer, but we cannot ignore other countries taking a different path and simply allow important industries, such as the one that will emerge to produce sustainable aviation fuel, to go elsewhere.
We will have that fuel anyway. The airlines will buy it and use it, and they will fly to other countries, which will have sustainable aviation fuel to put in the jets. We will have to do the same.
