The spectacle of another annual climate conference is getting under way in Dubai. Like Kabuki theatre, performative set pieces lead from one to the other: politicians and celebrities arrive by private jets; speakers predict imminent doom; hectoring NGOs cast blame; political negotiations become fraught and inevitably go overtime; and finally, the signing of a new agreement participants hope and pretend will make a difference.
This circus has repeated since the 1990s. Despite 27 previous conferences with iterations of ominous speeches and bold promises, global emissions have inexorably increased, punctuated just once by the economic shutdown of Covid-19. This year is likely to see higher emissions than ever before.
Almost every rich country preaches far more than it delivers. This is exemplified by the EU, which has promised more than anyone else, yet when forced by Russia’s invasion of Ukraine to cut off gas imports, went looking in Africa for more oil, gas and coal. Meanwhile, almost every poor country understandably prioritises prosperity, which means abundant, cheap and reliable energy — which still means fossil fuels.
Underpinning the climate summit farce is one big lie repeated over and over: that green energy is on the precipice of replacing fossil fuels in every aspect of our lives. This exaggeration is today championed by the International Energy Agency, which has turned from an impartial arbiter of energy data to the proponent of the far-fetched prediction that fossil fuels will peak within just seven years.
The claim ignores the fact that any transition away from fossil fuels is occurring only with enormous taxpayer-funded subsidies. And while major energy players such as Exxon and Chevron are moving back to investment in fossil fuels, big bets on green energy have failed spectacularly. Over the past 15 years alternative energy stocks have plummeted in value, thus sending the pensions of ordinary workers tumbling due to virtue-signalling pension companies, while general stocks have increased more than fourfold.
What won’t be acknowledged in the United Arab Emirates — because it has never been acknowledged at a global climate summit — is the awkward reality that while climate change has real costs, climate policy does too.
In most public conversations climate change costs are vastly exaggerated. Just consider how every heatwave is depicted as an end-of-the world, cataclysmic killer, while the far greater reductions in deaths from warmer winters pass without being remarked on. Yet the costs of climate policy are bizarrely ignored.
Analysing the balance between climate and policy costs has been at the heart of the study of climate change economics for more than three decades. Renowned economist William Nordhaus is the only climate change economist recognised with a Nobel prize. His research shows that we should absolutely do something about climate change: early cuts in fossil fuel emissions are cheap and will reduce the most dangerous temperature rises. But his work also shows that highly ambitious carbon reductions will be a bad deal, with phenomenally high costs and low additional benefits.
Climate activists, who insist we should listen to the science, have consistently ignored this research and encouraged rich world leaders to make ever-greater climate promises. Many leaders have even gone so far as to promise net-zero carbon emissions by 2050.
Despite this likely being the single costliest policy ever promised by world leaders, it was made without a single peer-reviewed estimate of the full costs. Earlier this year, a special issue of Climate Change Economics made the first such analysis.
This astonishing work has gone almost entirely unreported by any major news outlet. It shows that even with very generous assumptions, the benefits of pursuing net zero will slowly inch upwards over the century. By mid-century, the benefits — meaning the avoided costs from climate change — could reach about $1-trillion each year.
But the costs would be far, far higher. Three different modelled approaches all show far higher costs than benefits for every year throughout the 21st century and far into the next. By 2050, the annual costs of the policy range between $10-trillion and $43-trillion. That’s 4%-18% of global GDP. Consider that the total tax intake of all governments across the world today is about 15% of global GDP — and politicians would potentially have us spend more than that.
Across the century the benefit is 1.4% of global GDP while the cost averages out at 8.6% of global GDP. Every dollar in cost delivers perhaps 16c of climate benefits. Clearly, this is an atrocious use of money.
The only thing that could avoid this summit being a retread of 27 other failures is if politicians acknowledge the real cost of net zero policy — and instead of making more carbon cut promises, vow to dramatically increase green energy R&D.
This would help innovate the price of low-carbon energy below that of fossil fuels so every country in the world will want to make the switch. Instead of subsidising today’s still-inefficient technology and trying to brute force a transition by pushing up the price of fossil fuels, we need to make green technologies genuinely cheaper.
Sadly, that seems a far-fetched hope. Instead, this climate summit looks set to be another wasted opportunity producing yet more hot air.
