Grand CommitteeMy Lords, Governments are torpid in their response to the climate threat. This is, of course, because its worst impacts will not be manifest until the second half of the century, beyond the time horizon of political and even investment decisions. We are like the proverbial boiling frog, contented in a warming tank until it is too late to save itself.
Most of us do care about the life chances of children and grandchildren who will be alive in 2100, but even well-intentioned individuals feel helpless. Politicians respond to pressure from voters, and voters are responsive not to scientists but to charismatic influencers. I shall highlight a disparate quartet of these—first, Pope Francis, through his 2015 encyclical; secondly, our secular pope, David Attenborough; thirdly, Bill Gates; and, fourthly, Greta Thunberg. Thanks to those personalities, public opinion has shifted. More people care and the rhetoric of business has changed. Climate has gained prominence on the political agenda.
To take a small example, Michael Gove, when at Defra, introduced legislation to ban non-reusable drinking straws. He would not have done this had not David Attenborough’s TV series alerted millions of voters to the downsides of ocean pollution. Likewise, the public would accept regulations that constrain our driving, flying and eating behaviour, and they would support measures to nudge industry towards the circular economy. For instance, buildings with short-intended lifetimes contain materials such as girders and piping that are re-usable. Better still, of course, is to use timber rather than steel, and there has been remarkable progress in timber-frame buildings.
Achieving a net-zero target is a major technological challenge—let us not forget that—but it is a realistic challenge that could be met not just by the UK, which contributes only 2% of the world’s emissions, but by all the countries of the prosperous global North. However—crucially—that is not enough. By 2050, there will be 4 billion people in the global South. Their individual per capita energy consumption is currently less than a quarter of ours, but they will suffer most from global warming and its effects on food production and water. If they gain prosperity, as we surely hope, they could collectively by 2050 be using more energy than the global North does today. If that energy comes from fossil fuels, the world could then be as far from net zero as it is today, and the prospects dire for all, but especially for equatorial nations. It is crucial, therefore, that these nations do not track our trajectory of economic development but leapfrog directly to clean energy, just as they have adopted smartphones without ever having landlines. This benign scenario requires renewables, energy storage and perhaps nuclear to advance technically and fall in cost.
We in the UK contribute only 2% of the world’s emissions, but we could have more leverage if we led a campaign to establish a kind of mega-Marshall plan to stimulate these developments, best of all by collaborating with other countries in the global north. This is perhaps a kind of foreign aid that the public may well endorse ungrudgingly, and it could be to our economic benefit too.
