Halfway Between Kyoto and 2050: Zero Carbon Is a Highly Unlikely Outcome

The global goal to achieve “net-zero” carbon emissions by 2050 is impractical and unrealistic, finds a new study published today by the Fraser Institute, an independent, non-partisan Canadian public policy think-tank.

“The plan to eliminate fossil fuels and achieve a net-zero economy faces formidable economic, political and practical challenges,” said Vaclav Smil, professor emeritus at the University of Manitoba and author of Halfway Between Kyoto and 2050: Zero Carbon Is a Highly Unlikely Outcome.

Canada is now also committed to this goal. In 2021, the federal government passed legislation mandating that the country will achieve “net-zero” emissions—that is, will either emit no greenhouse gas emissions or offset its emissions through other activities (e.g. tree planting)—by 2050.

Yet, despite international agreements and significant spending and regulations by governments worldwide, global dependence on fossil fuels has steadily increased over the past three decades. By 2023, global fossil fuel consumption was 55 per cent higher than in 1997 (when the Kyoto Protocol was adopted). And the share of fossil fuels in global energy consumption has only slightly decreased, dropping from 86 per cent in 1997 to 82 per cent in 2022 (the latest year of complete production data).

Widespread adoption of electric vehicles—also a key component of Ottawa’s net-zero plan—by 2040 will require more than 40 times more lithium and up to 25 times more cobalt, nickel and graphite worldwide (compared to 2020 levels). There are serious questions about the ability to achieve such increases in mineral and metal production.

Although the eventual cost of global decarbonization cannot be reliably quantified, achieving zero carbon by 2050 would require spending substantially higher than for any previous long-term peacetime commitments. Moreover, high-income countries (including Canada) are also expected to finance new energy infrastructure in low-income economies, further raising their decarbonization burdens.

Finally, achieving net-zero requires extensive and sustained global cooperation among countries—including China and India—that have varied levels of commitment to decarbonization.

“Policymakers must face reality—while ending our reliance on fossil fuels may be a desirable long-term goal, it cannot be accomplished quickly or inexpensively,” said Elmira Aliakbari, director of natural resource studies at the Fraser Institute.

Summary

This essay evaluates past carbon emission reduction and the feasibility of eliminating fossil fuels to achieve net-zero carbon by 2050.
Despite international agreements, government spending and regulations, and technological advancements, global fossil fuel consumption surged by 55 percent between 1997 and 2023. And the share of fossil fuels in global energy consumption has only decreased from nearly 86 percent in 1997 to approximately 82 percent in 2022.
The first global energy transition, from traditional biomass fuels such as wood and charcoal to fossil fuels, started more than two centuries ago and unfolded gradually. That transition remains incomplete, as billions of people still rely on traditional biomass energies for cooking and heating.
The scale of today’s energy transition requires approximately 700 exajoules of new non-carbon energies by 2050, which needs about 38,000 projects the size of BC’s Site C or 39,000 equivalents of Muskrat Falls.
Converting energy-intensive processes (e.g., iron smelting, cement, and plastics) to non-fossil alternatives requires solutions not yet available for largescale use.
The energy transition imposes unprecedented demands for minerals including copper and lithium, which require substantial time to locate and develop mines.
To achieve net-zero carbon, affluent countries will incur costs of at least 20 percent of their annual GDP.
While global cooperation is essential to achieve decarbonization by 2050, major emitters such as the United States, China, and Russia have conflicting interests.
To eliminate carbon emissions by 2050, governments face unprecedented technical, economic and political challenges, making rapid and inexpensive transition impossible.

Trump opens door to Iranian oil exports

U.S. President Donald Trump’s chaotic foreign policy is unravelling years of pressure on Iran and fuelling a surge of Iranian oil into global markets. His recent pivot to allow China to buy Iranian crude, despite previously trying to crush those exports, marks a sharp shift from strategic pressure to transactional diplomacy.

This unpredictability isn’t just confusing allies—it’s transforming global oil flows. One day, Trump vetoes an Israeli plan to assassinate Iran’s supreme leader, Ayatollah Khamenei. Days later, he calls for Iran’s unconditional surrender. After announcing a ceasefire between Iran, Israel and the United States, Trump praises both sides then lashes out at them the next day.

The biggest shock came when Trump posted on Truth Social that “China can now continue to purchase Oil from Iran. Hopefully, they will be purchasing plenty from the U.S., also.” The statement reversed the “maximum pressure” campaign he reinstated in February, which aimed to drive Iran’s oil exports to zero. The campaign reimposes sanctions on Tehran, threatening penalties on any country or company buying Iranian crude,
with the goal of crippling Iran’s economy and nuclear ambitions.

This wasn’t foreign policy—it was deal-making. Trump is brokering calm in the Middle East not for strategy, but to boost American oil sales to China. And in the process, he’s giving Iran room to move.

The effects of this shift in U.S. policy are already visible in trade data. Chinese imports of Iranian crude hit record levels in June. Ship-tracking firm Vortexa reported more than 1.8 million barrels per day imported between June 1 and 20. Kpler data, covering June 1 to 27, showed a 1.46 million bpd average, nearly 500,000 more than in May.

Much of the supply came from discounted May loadings destined for China’s independent refineries—the so-called “teapots”—stocking up ahead of peak summer demand. After hostilities broke out between Iran and Israel on June 12, Iran ramped up exports even further, increasing daily crude shipments by 44 per cent within a week.

Iran is under heavy U.S. sanctions, and its oil is typically sold at a discount, especially to China, the world’s largest oil importer. These discounted barrels undercut other exporters, including U.S. allies and global producers like Canada, reducing global prices and shifting power dynamics in the energy market.

All of this happened with full knowledge of the U.S. administration. Analysts now expect Iranian crude to continue flowing freely, as long as Trump sees strategic or economic value in it—though that position could reverse without warning.

Complicating matters is progress toward a U.S.-China trade deal. Commerce Secretary Howard Lutnick told reporters that an agreement reached in May has now been finalized. China later confirmed the understanding. Trump’s oil concession may be part of that broader détente, but it comes at the cost of any consistent pressure on Iran.

Meanwhile, despite Trump’s claims of obliterating Iran’s nuclear program, early reports suggest U.S. strikes merely delayed Tehran’s capabilities by a few months. The public posture of strength contrasts with a quieter reality: Iranian oil is once again flooding global markets.

With OPEC+ also boosting output monthly, there is no shortage of crude on the horizon. In fact, oversupply may once again define the market—and Trump’s erratic diplomacy is helping drive it.

For Canadian producers, especially in Alberta, the return of cheap Iranian oil can mean downward pressure on global prices and stiffer competition in key markets. And with global energy supply increasingly shaped by impulsive political decisions, Canada’s energy sector remains vulnerable to forces far beyond its borders.

This is the new reality: unpredictability at the top is shaping the oil market more than any cartel or conflict. And for now, Iran is winning.

Mines demonstrate significant strides through technological innovation

Tailings are a byproduct of mining operations around the world.

In Alberta’s oil sands, tailings are a fluid mixture of water, sand, silt, clay and residual bitumen generated during the extraction process.

Engineered basins or “tailings ponds” store the material and help oil sands mining projects recycle water, reducing the amount withdrawn from the Athabasca River.

In 2023, 79 per cent of the water used for oil sands mining was recycled, according to the latest data from the Alberta Energy Regulator (AER).

Decades of operations, rising production and federal regulations prohibiting the release of process-affected water have contributed to a significant accumulation of oil sands fluid tailings.

The Mining Association of Canada describes that:

“Like many other industrial processes, the oil sands mining process requires water.

However, while many other types of mines in Canada like copper, nickel, gold, iron ore and diamond mines are allowed to release water (effluent) to an aquatic environment provided that it meets stringent regulatory requirements, there are no such regulations for oil sands mines.

Instead, these mines have had to retain most of the water used in their processes, and significant amounts of accumulated precipitation, since the mines began operating.”

Despite this ongoing challenge, oil sands mining operators have made significant strides in reducing fluid tailings through technological innovation.

This is demonstrated by reductions in “legacy fluid tailings” since 2015.

Legacy Fluid Tailings vs. New Fluid Tailings

As part of implementing the Tailings Management Framework introduced in March 2015, the AER released Directive 085: Fluid Tailings Management for Oil Sands Mining Projects in July 2016.

Directive 085 introduced new criteria for the measurement and closure of “legacy fluid tailings” separate from those applied to “new fluid tailings.”

Legacy fluid tailings are defined as those deposited in storage before January 1, 2015, while new fluid tailings are those deposited in storage after January 1, 2015.

The new rules specified that new fluid tailings must be ready to reclaim ten years after the end of a mine’s life, while legacy fluid tailings must be ready to reclaim by the end of a mine’s life.

Total Oil Sands Legacy Fluid Tailings

Alberta’s oil sands mining sector decreased total legacy fluid tailings by approximately 40 per cent between 2015 and 2024, according to the latest company reporting to the AER.

Total legacy fluid tailings in 2024 were approximately 623 million cubic metres, down from about one billion cubic metres in 2015.

The reductions are led by the sector’s longest-running projects: Suncor Energy’s Base Mine (opened in 1967), Syncrude’s Mildred Lake Mine (opened in 1978), and Syncrude’s Aurora North Mine (opened in 2001). All are now operated by Suncor Energy.

The Horizon Mine, operated by Canadian Natural Resources (opened in 2009) also reports a significant reduction in legacy fluid tailings.

The Muskeg River Mine (opened in 2002) and Jackpine Mine (opened in 2010) had modest changes in legacy fluid tailings over the period. Both are now operated by Canadian Natural Resources.

Imperial Oil’s Kearl Mine (opened in 2013) and Suncor Energy’s Fort Hills Mine (opened in 2018) have no reported legacy fluid tailings.

Suncor Energy Base Mine

Between 2015 and 2024, Suncor Energy’s Base Mine reduced legacy fluid tailings by approximately 98 per cent, from 293 million cubic metres to 6 million cubic metres.

Syncrude Mildred Lake Mine

Between 2015 and 2024, Syncrude’s Mildred Lake Mine reduced legacy fluid tailings by approximately 15 per cent, from 457 million cubic metres to 389 million cubic metres.

Syncrude Aurora North Mine

Between 2015 and 2024, Syncrude’s Aurora North Mine reduced legacy fluid tailings by approximately 25 per cent, from 102 million cubic metres to 77 million cubic metres.

Canadian Natural Resources Horizon Mine

Between 2015 and 2024, Canadian Natural Resources’ Horizon Mine reduced legacy fluid tailings by approximately 36 per cent, from 66 million cubic metres to 42 million cubic metres.

Total Oil Sands Fluid Tailings

Reducing legacy fluid tailings has helped slow the overall growth of fluid tailings across the oil sands sector.

Without efforts to reduce legacy fluid tailings, the total oil sands fluid tailings footprint today would be approximately 1.6 billion cubic metres.

The current fluid tailings volume stands at approximately 1.2 billion cubic metres, up from roughly 1.1 billion in 2015.
