I beg to move,
That this House has considered net zero targets and decarbonising transport.
It is a genuine pleasure to see you in the Chair, Ms Nokes, and to have an opportunity to serve under your chairmanship. Tackling climate change is the defining challenge of our age. In the developed world—the rich world, with our higher per capita emissions—our responsibility is all the greater. I was proud last year when the UK became the first advanced economy to set in legislation a date for net zero, and I am pleased today that we are taking a further practical step by bringing forward the phase-out of petrol and diesel vehicles to 2035.
The UK has been decarbonising more quickly than any other G20 country, although one would not know that from hearing most commentary in this country. One would think that it is because of some accounting methodology, the cunning exclusion of some categories, or the financial crash of 2007-08. One would think that it all happened before 2010 and that nothing has improved since, or that it was because we have exported all our emissions to somewhere else in the world. But no, this country has made good and sustained progress on decarbonisation under Governments of both types. The greatest part of that progress has been made on energy decarbonisation, and the reality is that there is a limit on how much further we can go in that area with current technology, because of the intermittent nature of the sources—the sun and the wind. It will change as battery technology improves, but that is the situation today. We have made good progress, but it is not enough. To hit our net zero 2050 target, we need to increase the decrease, as it were, in our rate of emissions by about 30% compared with what we have managed per annum since 1990. Partly because of the success in energy, transport is now the biggest single source of emissions.
There are many different aspects of decarbonising transport, and we have only 90 minutes for this debate. Other colleagues might talk about active travel, such as walking and cycling, or about shipping, on-demand buses, the electrification of rail, heavy goods vehicles, the development of autonomous vehicles, alternative jet fuel technology or what could be the huge potential, eventually, of hydrogen—and it would be a turn-up for the books if nobody mentioned either HS2 or Heathrow airport. We could talk about many different aspects, but I will concentrate on roads, which is the biggest category, and specifically cars.
