Canada has only reduced carbon emissions by 4 per cent in the 25 years from 1979-2022, from 86% to 82%. That emissions will drop the remaining 82% in the next 25 years is an impossible dream
By Vaclav Smil, Fraser Institute, May 28, 2024
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 of Fraser Institute report
- 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.
