Net zero’s cost-benefit ratio is crazy high

From the Fraser Institute
The best academic estimates show that over the century, policies to achieve net zero would cost every person on Earth the equivalent of more than CAD $4,000 every year. Of course, most people in poor countries cannot afford anywhere near this. If the cost falls solely on the rich world, the price-tag adds up to almost $30,000 (CAD) per person, per year, over the century.
Canada has made a legal commitment to achieve “net zero” carbon emissions by 2050. Back in 2015, then-Prime Minister Trudeau promised that climate action will “create jobs and economic growth” and the federal government insists it will create a “strong economy.” The truth is that the net zero policy generates vast costs and very little benefit—and Canada would be better off changing direction.
Achieving net zero carbon emissions is far more daunting than politicians have ever admitted. Canada is nowhere near on track. Annual Canadian CO₂ emissions have increased 20 per cent since 1990. In the time that Trudeau was prime minister, fossil fuel energy supply actually increased over 11 per cent. Similarly, the share of fossil fuels in Canada’s total energy supply (not just electricity) increased from 75 per cent in 2015 to 77 per cent in 2023.
Over the same period, the switch from coal to gas, and a tiny 0.4 percentage point increase in the energy from solar and wind, has reduced annual CO₂ emissions by less than three per cent. On that trend, getting to zero won’t take 25 years as the Liberal government promised, but more than 160 years. One study shows that the government’s current plan which won’t even reach net-zero will cost Canada a quarter of a million jobs, seven per cent lower GDP and wages on average $8,000 lower.
Globally, achieving net-zero will be even harder. Remember, Canada makes up about 1.5 per cent of global CO₂ emissions, and while Canada is already rich with plenty of energy, the world’s poor want much more energy.
In order to achieve global net-zero by 2050, by 2030 we would already need to achieve the equivalent of removing the combined emissions of China and the United States — every year. This is in the realm of science fiction.
The painful Covid lockdowns of 2020 only reduced global emissions by about six per cent. To achieve net zero, the UN points out that we would need to have doubled those reductions in 2021, tripled them in 2022, quadrupled them in 2023, and so on. This year they would need to be sextupled, and by 2030 increased 11-fold. So far, the world hasn’t even managed to start reducing global carbon emissions, which last year hit a new record.
Data from both the International Energy Agency and the US Energy Information Administration give added cause for skepticism. Both organizations foresee the world getting more energy from renewables: an increase from today’s 16 per cent to between one-quarter to one-third of all primary energy by 2050. But that is far from a transition. On an optimistically linear trend, this means we’re a century or two away from achieving 100 percent renewables.
Politicians like to blithely suggest the shift away from fossil fuels isn’t unprecedented, because in the past we transitioned from wood to coal, from coal to oil, and from oil to gas. The truth is, humanity hasn’t made a real energy transition even once. Coal didn’t replace wood but mostly added to global energy, just like oil and gas have added further additional energy. As in the past, solar and wind are now mostly adding to our global energy output, rather than replacing fossil fuels.
Indeed, it’s worth remembering that even after two centuries, humanity’s transition away from wood is not over. More than two billion mostly poor people still depend on wood for cooking and heating, and it still provides about 5 per cent of global energy.
Like Canada, the world remains fossil fuel-based, as it delivers more than four-fifths of energy. Over the last half century, our dependence has declined only slightly from 87 per cent to 82 per cent, but in absolute terms we have increased our fossil fuel use by more than 150 per cent. On the trajectory since 1971, we will reach zero fossil fuel use some nine centuries from now, and even the fastest period of recent decline from 2014 would see us taking over three centuries.
Global warming will create more problems than benefits, so achieving net-zero would see real benefits. Over the century, the average person would experience benefits worth $700 (CAD) each year.
But net zero policies will be much more expensive. The best academic estimates show that over the century, policies to achieve net zero would cost every person on Earth the equivalent of more than CAD $4,000 every year. Of course, most people in poor countries cannot afford anywhere near this. If the cost falls solely on the rich world, the price-tag adds up to almost $30,000 (CAD) per person, per year, over the century.
Every year over the 21st century, costs would vastly outweigh benefits, and global costs would exceed benefits by over CAD 32 trillion each year.
We would see much higher transport costs, higher electricity costs, higher heating and cooling costs and — as businesses would also have to pay for all this — drastic increases in the price of food and all other necessities. Just one example: net-zero targets would likely increase gas costs some two-to-four times even by 2030, costing consumers up to $US52.6 trillion. All that makes it a policy that just doesn’t make sense—for Canada and for the world.

The stupidity of Net Zero | Bjorn Lomborg on how climate alarmism leads to economic crisis

From spiked on YouTube
Note: This interview is focused on Europe and the UK. It very much applies to Canada. The 2025 Federal Election which will see Canadians choose between a more common sense approach, and spending the next 4 years continuing down the path of pursuing “The Stupidity of Net Zero”.
European industry is in freefall, and Net Zero is to blame.
Here, climate economist Bjorn Lomborg – author of Best Things First and False Alarm – explains how panic over climate change is doing far more damage than climate change itself. Swapping cheap and dependable fossil fuels for unreliable and expensive renewables costs our economies trillions, but for little environmental gain, Lomborg says.
Plus, he tackles the myth of the ‘climate apocalypse’ and explains why there are more polar bears than ever.

Don’t double-down on net zero again

From the Fraser Institute
In the preamble to the Paris Agreement, world leaders loftily declared they would keep temperature rises “well below 2°C” and perhaps even under 1.5°C. That was never on the cards—it would have required the world’s economies to effectively come to a grinding halt.
The truth is that the “net zero” green agenda, based on massive subsidies and expensive legislation, will likely cost more than CAD$38 trillion per year across the century, making it utterly unattractive to voters in almost every nation on Earth.
When President Trump withdrew the United States from the Paris Climate Agreement for the first time in 2017, then-Canadian Prime Minister Justin Trudeau was quick to claim the moral high ground, declaring that “we will continue to work with our domestic and international partners to drive progress on one of the greatest challenges we face as a world.”
Trudeau has now been swept from the stage. On his first day back in office, President Trump signed an executive order that again begins the formal, twelve-month-long process of withdrawing the United States from the Paris Agreement.
It will be tempting for Canada to step anew into the void left by the United States. But if the goal is to make effective climate policy, whoever is Canada’s prime minister needs to avoid empty virtue signaling. It would be easy for Canada to declare again that it’ll form a “coalition of the willing” with Europe. The truth is that, just like last time, that approach would do next to nothing for the planet.
Climate summits have generated vast amounts of attention and breathless reporting giving the impression that they are crucial to the planet’s survival. Scratch the surface, and the results are far less impressive. In 2021, the world promised to phase-down coal. Since then, global coal consumption has only gone up. Virtually every summit has promised to cut emissions but they’ve increased almost every single year, and 2024 reached a new high.
Way before the Paris Agreement was inked, the Kyoto Protocol was once sold as a key part of the solution to global warming. Yet studies show it achieved virtually nothing for climate change.
In the preamble to the Paris Agreement, world leaders loftily declared they would keep temperature rises “well below 2°C” and perhaps even under 1.5°C. That was never on the cards—it would have required the world’s economies to effectively come to a grinding halt.
The truth is that the “net zero” green agenda, based on massive subsidies and expensive legislation, will likely cost more than CAD$38 trillion per year across the century, making it utterly unattractive to voters in almost every nation on Earth.
The awkward reality is that emissions from Canada, the EU, and other countries pursuing climate policies matter little in the 21st century. Canada likely only makes up about 1.5 per cent of the world’s emissions. Add together Canada’s output with that of every single country of the rich-world OECD, and this only makes up about one-fifth of global emissions this century, using the United Nations’ ‘middle of the road’ forecast. The other four-fifths of emissions come mostly from China, India and Africa.
Even if wealthy countries like Canada impoverish themselves, the result is tiny — run the UN’s standard climate model with and without Canada going net-zero in 2050, and the difference is immeasurable even in 2100. Moreover, much of the production and emissions just move to the Global South—and even less is achieved.

One good example of this is the United Kingdom, which—like Prime Minister Trudeau once did—has leaned into climate policies, suggesting it would lead the efforts for strong climate agreements. British families are paying a heavy price for their government going farther than almost any other in pursuing the climate agenda: just the inflation-adjusted electricity price, weighted across households and industry, has tripled from 2003 to 2023, mostly because of climate policies. This need not have been so: the US electricity price has remained almost unchanged over the same period.
The effect on families is devastating. Had prices stayed at 2003 levels, an average family-of-four would now be spending CAD$3,380 on electricity—which includes indirect industry costs. Instead, it now pays $9,740 per year.
Rising electricity costs make investment less attractive: European businesses pay triple US electricity costs, and nearly two-thirds of European companies say energy prices are now a major impediment to investment.
The Paris Treaty approach is fundamentally flawed. Carbon emissions continue to grow because cheap, reliable power, mostly from fossil fuels, drives economic growth. Wealthy countries like Canada, the US, and European Union members have started to cut emissions—often by shifting production elsewhere—but the rest of the world remains focused on eradicating poverty.
Poor countries will rightly reject making carbon cuts unless there is a huge flow of “climate aid” from rich nations, and want trillions of US dollars per year. That won’t happen. The new US government will not pay, and the other rich countries cannot foot the bill alone.
Without these huge transfers of wealth, China, India and many other developing countries will disavow expensive climate policies, too. This potentially leaves a rag-tag group led by a few Western European progressive nations, which can scarcely afford their own policies and have no ability to pay off everyone else.
When the United States withdrew from the Paris Agreement in 2017, Canada’s doubling down on the Paris Treaty sent the signal that it would be worthwhile spending hundreds of trillions of dollars to make no real difference to temperatures. We fool ourselves if we pretend that doing so for a second time will help the planet.
We need to realize that fixing climate change isn’t about sanctimonious summits, lofty speeches, and bluster. In coming weeks I’ll outline the case for efficient policies like innovation, adaptation and prosperity.
