For decades, the climate movement has led with the moral argument. Millions will die. Cities will flood. Species will vanish. Coral reefs will bleach and disappear.

These arguments are true — every one of them — but they have not been enough to move governments to act at the scale the science demands. Certainly not in this political moment, where economic pragmatism is the order of the day and the word “environment” has become politically toxic in some quarters.

Something may be shifting. The UN’s landmark report A Future We Choose — released in December 2025 — reads less like a traditional environmental alarm and more like a brief to a board of directors.

Its central argument is economic: staying on the fossil fuel path is ruinously expensive, and investing in the transition is enormously profitable.

It is, in spirit, the climate movement’s equivalent of James Carville’s famous insight during Bill Clinton’s 1992 presidential campaign — when Carville refocused the entire race by pinning a sign to the wall of campaign headquarters that read: “It’s the economy, stupid.”

The point wasn’t that other things didn’t matter. It was that leading with the economic argument was the move that would actually win.

That reframe arrived at a particularly pointed moment in Canada. In late November 2025, Prime Minister Mark Carney and Alberta Premier Danielle Smith stood together in Calgary to announce what they called a “grand bargain” — a memorandum of understanding committing the federal government to scrap Canada’s planned oil and gas emissions cap, delay methane regulations by five years, and support construction of a new pipeline designed to carry one million barrels of Alberta bitumen per day to the west coast. The stated goal: to make Canada a fossil fuel superpower.

Twelve days later, the United Nations released A Future We Choose.

What the report is — and why it matters

A Future We Choose is the seventh edition of the Global Environment Outlook, or GEO-7 — the UN Environment Programme’s flagship scientific assessment of the state of our planet. It is not an advocacy document. It is the product of 287 multidisciplinary scientists from 82 countries, with contributions from over 800 reviewers worldwide. It took three years to produce and runs to 1,240 pages. It is, by any reasonable measure, the most comprehensive scientific assessment of the global environment ever carried out.

The report does something important that a lot of climate science communication fails to do: it doesn’t just describe the problem. It models two futures in detail — what happens if we stay on our current path, and what happens if we don’t — and it puts hard economic numbers on both. That framing is deliberate. This is a report designed to be read by finance ministers and CEOs, not just scientists and environmentalists.

The trajectory we’re on

The emissions picture the report paints is not encouraging. Global greenhouse gas emissions have risen 1.5% every year since 1990 without interruption. In 2024, global temperatures hit 1.55°C — the highest ever recorded. On a business-as-usual path, we reach 75 gigatonnes of CO₂ equivalent per year by 2050 — nearly 50% higher than today.

The physical consequences of that trajectory are not abstract. The report identifies a series of tipping points that, once crossed, become irreversible: the collapse of the Greenland and West Antarctic ice sheets, the thawing of permafrost releasing massive quantities of methane, the withering of the Amazon into savannah, the disappearance of nearly every warm-water coral reef on Earth. These are not scenarios from the distant future. The report warns they could be triggered within decades, under trajectories that current policies are not ruling out.

The economic argument — which should matter to everyone

What makes GEO-7 particularly useful for anyone trying to make the case for action to a business or policy audience is its economic modelling. The report doesn’t frame the climate transition as a cost — it frames inaction as the much larger one.

Under a business-as-usual scenario, climate change alone is projected to shave 4% off global GDP every year by 2050. By 2100, that rises to 20% — one dollar in every five, year after year, permanently. Climate disasters already cost the world an average of $143 billion annually. Air pollution — driven primarily by fossil fuel combustion — caused $8.1 trillion in health-related losses in 2019 alone.

On the other side of the ledger, the transformation pathway — the one that means moving away from fossil fuels — requires roughly $8 trillion per year in investment through 2050. The return: $20 trillion per year in economic benefits by 2070, rising to $100 trillion per year by 2100. That’s equivalent to a quarter of global GDP, every year, indefinitely.

Put simply: the math favours action by a wide margin, and the gap grows with every decade of delay.

Beyond the economic returns, the transformation pathway would also prevent more than 9 million premature deaths per year — most of them caused by air pollution from burning fossil fuels — and lift 200 million people out of hunger and 150 million out of extreme poverty.

The Canada problem

Here is the juxtaposition that should give Canadians pause.

The Carney government’s justification for the Alberta MOU was economic. US tariffs and trade uncertainty, the argument went, meant Canada needed to unlock its energy sector to protect jobs and GDP. Expanding oil and gas production was framed as a pragmatic response to a difficult moment.

GEO-7’s data makes the counterargument clearly and without political agenda: the economic risks of staying on the fossil fuel path are far larger than the economic risks of transitioning off it. Countries that use short-term economic pressure as a reason to delay climate action are not protecting their economies — they are mortgaging them.

There is also a specific Canadian dimension worth noting. As I’ve written before, around 85% of emissions from oil and gas come from combustion, not production. When Canada expands oil sands output, the emissions from burning that oil abroad don’t show up in our national totals — but they are real, they contribute to global warming, and the atmosphere doesn’t care how we account for them. In 2023, Canada’s exported fossil fuel emissions topped one billion tonnes of CO₂ — significantly exceeding our total domestic emissions of 702 million tonnes. Expanding production makes that number larger.

Prime Minister Carney has acknowledged that Canada will miss its 2030 and 2035 climate targets. That is a significant admission — and GEO-7 makes clear what missing those targets means, not just for the climate, but for Canada’s long-term economic interests.

The two-economy world

There is a larger frame worth keeping in mind as Canada makes these decisions. The world is not simply dividing along environmental lines — it is dividing along economic ones. Countries that are moving aggressively toward clean energy, electrification, and the circular economy are building the industrial base of the next several decades. Countries that are doubling down on fossil fuels are betting on an industry that every credible long-term forecast — including GEO-7 — projects will decline.

This is not an abstract concern. The competitiveness gap between these two camps will compound over time. Clean energy manufacturing, battery technology, grid infrastructure, and green hydrogen are growth industries attracting trillions in investment. Oil and gas is a mature industry facing structural demand decline as electrification accelerates globally. Countries that lock in fossil fuel infrastructure today — pipelines, export terminals, long-term supply contracts — are not just making an environmental choice. They are making a bet on which economy will be more valuable in 2040, 2050, and 2060.

Canada’s MOU with Alberta, if it leads to a final agreement in April as intended, would lock in decades of additional oil sands development. GEO-7’s economic modelling suggests that the countries building the clean economy will capture $20 trillion per year in benefits by 2070. The question Canada needs to answer honestly is not whether we can afford the transition — it’s whether we can afford to be on the wrong side of it.

A future we choose

The title of the report is worth sitting with. A Future We Choose is not a statement of despair — it’s a statement of agency. The scientists who wrote it are explicit that the transformation pathway is still available. The window hasn’t closed. The economic case for taking it is stronger than the case for staying put.

But windows don’t stay open indefinitely, and the tipping points the report describes are, by definition, irreversible once crossed. Every policy decision that moves in the wrong direction — a scrapped emissions cap here, a delayed methane regulation there — narrows the window a little more.

Canada has not yet made a final choice — the MOU commits to negotiating a full agreement by April, and that window is still open. But the direction of travel is clear, and it runs counter to everything the world’s most comprehensive environmental assessment is telling us. The countries that will thrive in the decades ahead are not the ones that extracted the most oil. They are the ones that moved fastest to build what comes next. Canada has the talent, the resources, and the industrial capacity to be on the right side of that divide.

The question is whether our political leaders will choose to get there.
