I beg to move,
That this House has considered the UK’s Climate Progress: the Committee on Climate Change’s 2021 Progress Report.
It is a pleasure to serve under your chairmanship, Sir Christopher. It is slightly regrettable that a similar debate is taking place in the main Chamber as we speak; it would have been nice to be able to speak in both, but this is one of the scheduling things that happens.
I think we all agree that tackling climate change is the biggest challenge facing humankind at present. Global temperatures have so far risen by 1.2° centigrade over the last century, and they are currently rising at about 0.25° per decade. That is being driven by the rise in greenhouse gas emissions—most significantly, carbon dioxide. Carbon dioxide is now 429 parts per million in the atmosphere, which is 50% higher than before the industrial revolution. Human civilisation is destroying the benign climate that our planet has enjoyed for the last 20,000 years and that enabled human civilisation to flourish in the first place. Our generation has a moral duty to pass on to future generations a planet that is sustainable, but it is also in our generation’s self-interest to achieve that.
I am not a natural doom-monger but an optimist at heart. We have had far more than our share of dark times over the last couple of years, so I want to highlight some good news. According to Our World in Data, a fantastic source of information, the UK emitted less carbon dioxide per capita in 2019 than in any year since 1859, when the industrial revolution was just gathering pace—with the one exception of 1926, which was the year of the general strike. Our per capita CO2 emissions are the lowest they have been for a century and a half. In total, our CO2 emissions have declined by almost a half since the benchmark year of 1990. That is not just a bigger decline than in any other G7 country; it is actually a bigger decline than in any G20 country.
“World-leading” may be a much-abused phrase, but it really is true that the UK is world-leading on reaching towards net zero. Our emissions per capita are now less than those of China, and they are one third of the levels in US, Canada and Australia. We emit less per capita than the EU average, less per person than Germany and less even than the eco-leaders Norway and Denmark. When I meet parliamentarians from other countries who are interested in environmental issues, the most frequent question they ask is: what is the UK’s secret to doing so well in reaching towards net zero?
At the beginning of the industrial revolution, the UK was responsible for almost exactly 100% of global greenhouse gas emissions. We are now responsible for just 1%. That is a tribute to the hard work and leadership of this and past UK Governments, and I welcome the announcements that we had this week, which I will refer to later. It is also a tribute to those in environment groups and industry who have worked so hard to raise awareness of climate change and help tackle it. Their efforts are bearing fruit.
In its 2021 report to Parliament on reducing emissions, the Climate Change Committee recognises the UK’s achievements. It says:
“The UK has a leading record in reducing its own emissions”.
That leadership role really matters as we head off to Glasgow for COP26, which the UK is obviously leading. We have enshrined in law not just reaching net zero by 2050, but a 78% reduction in emissions by 2035. That is the most ambitious nationally determined contribution that any country in the world is bringing to COP26— I hope that point is being made in the debate taking place in the main Chamber. Fingers crossed, such leadership will help us achieve more ambitious contributions from other countries. In turn, that will hopefully keep global warming down to a maximum of 1.5° centigrade—we need to keep 1.5 alive.
When it comes to net zero, we as a country can be justifiably be proud of what we have achieved so far. That is absolutely no excuse for complacency, but it means that our efforts so far have been worth while—they are paying off. But now the bad news: we are still not doing enough. That is the overriding message from the Climate Change Committee’s 2021 progress report. If we are to get to net zero by 2050, the hard work has yet to come. We have reduced emissions by around a half over the past three decades, as I said, but it will be far more difficult to do the same over the next three decades. The CCC says:
“UK emissions are nearly 50% below 1990 levels, but the journey to Net Zero is far from half done.”
In policy terms, we have cut the fat but we are now down to the bone.
Most of our cuts in emissions have come from decarbonising the power sector. We are on the brink of phasing out coal, and wind power is now our main source of electricity—that was unthinkable when I was environment editor of The Observer and The Times 20 years ago. Other sectors have done well: emissions from industry have fallen by 53% since 1990 and emissions from waste are down by 69% as a result of sending less biodegradable matter to landfills. More topically, the CCC has reported that we had the biggest ever drop in emissions last year; as a result of the pandemic, they fell by 13%. Unsurprisingly, the biggest fall was in aviation emissions, which were down 60% last year alone. However, clearly that is a one-off and already bouncing back.
The good news is that our reductions in emissions mean that, in purely numerical terms, as of now we are on track to meet net zero by 2050. Our reductions have been big enough to get there. The CCC said that the rate of the reduction since 2012—over the last nine years—is enough to get us to net zero by 2050 if we carry on reducing at that rate. This is a very big “if”. The CCC report, using charts and graphs, said that we do not have the policies in place to keep reducing at that rate. The key message was that
“The Government has made historic climate promises in the past year, for which it deserves credit. However, it has been too slow to follow these with delivery.”
It warned that we will not meet our emission targets for 2028 to 2032—the so-called fifth carbon budget—let alone the sixth carbon budget of 2033 to 2037. At the time of its publication in June, it estimated that the credible policies covered only about 20% of the reductions to meet the sixth carbon budget.
This is all very perplexing: how can we be both on track, as I said earlier, but also off track? The best analogy that I can come up with is the 2010 film “Unstoppable”, about a runaway train—a very good film for those who want to pass a couple of hours. Our heroes, Denzel Washington and Chris Pine, keep the speeding, out-of-control train on track, but they know there is a sharp bend ahead. It is inevitable that when the train reaches that bend it will fly off the track and kill lots of people in houses, unless they do something dramatic. Likewise, we need to do something dramatic to stay on track for net zero by 2050. That means we cannot just keep on with the policies that have served us so far.
The decarbonisation of power generation is a one-off that cannot be done forever: once we have phased out coal, we cannot phase it out again. The Government have just committed to making all power generation net zero by 2035—something that I have publicly called for and welcome. However, that means that power, the sector that has done most of the heavy lifting to net zero, will not be able to do any more from 2035. Other sectors will have to make up the difference.
