Introduction
The Paris Agreement’s greatest challenges lie not only in international negotiations, but in how countries reconcile global climate commitments with domestic energy policies. Canada provides a vivid example of this tension, with its climate leadership narrative on the global stage and its ongoing support for oil sands and liquefied natural gas (LNG) projects at home.
Canada’s Oil Sands, LNG Projects, and Climate Targets
In 2025, Canada pledged to cut emissions by 45–50% below 2005 levels by 2035 and achieve net-zero by 2050. Yet, the oil sands in Alberta remain a significant source of carbon-intensive crude despite concerns over its impact on endangered species. Meanwhile, LNG projects in British Columbia are marketed as a transition fuel, but risk locking in fossil fuel infrastructure well beyond 2030. Moreso, critics argue that the LNG Canada Project approved as Canada’s largest LNG facility undermines Canada’s Paris targets.
Additionally, Indigenous-led legal challenges highlight the tension between climate policy, Indigenous rights, and energy development. Despite opposition from Indigenous groups and environmentalists, the federal government also purchased and pushed forward the Trans Mountain Pipeline Expansion project, arguing it balances economic and environmental priorities. Multiple legal challenges cited inadequate consultation and climate risks, though most were dismissed. This raises a crucial question: Can Canada realistically meet its Paris Agreement commitments while continuing to expand fossil fuel production?
Legal Tensions Between Federal and Provincial Policies
Under Canada’s constitutional framework, provinces retain significant authority over natural resources, while the federal government leads on international commitments. This has led to a jurisdictional tug-of-war where the federal government implements national climate policies such as the carbon pricing system, methane regulations, and clean fuel standards. Whereas provinces like Alberta and Saskatchewan, however, have resisted such policies, arguing federal policies undermine their economies and jurisdiction.
In fact, several provinces also challenged the federal carbon price, culminating in the 2021 Supreme Court ruling upholding it as constitutional. The Supreme Court of Canada upheld the federal carbon pricing law in 2021, affirming the Federal Government’s role in addressing climate change as a matter of “national concern” (Reference re Greenhouse Gas Pollution Pricing Act, 2021 SCC 11). Illustrating that domestic courts are becoming arenas for negotiating the balance between domestic energy expansion and international climate obligations. Despite this ruling, political and legal conflicts continue, especially with Alberta challenging federal emissions caps and clean electricity regulations. Moreover in 2025, the Canadian government proposed a four phased permanent repeal of the fuel charge under the Greenhouse Gas Pollution Pricing Act (GGPPA).
Conclusion
The Paris Agreement requires countries like Canada to align national policies with ambitious climate goals. Yet, Canada’s continued support for oil sands and LNG projects shows a persistent gap between rhetoric and reality. Courts can mediate tensions, but ultimately, political will and coherent policy alignment are necessary to resolve this collision course. If Canada wants to credibly lead on climate change internationally, it must reconcile its Paris commitments with its energy policies at home. The world—and future generations—are watching.
