Renowned energy expert says Ottawa’s ‘net-zero’ emissions plan impractical and unrealistic

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

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.
