In the fall of 2020, Environment and Climate Change Canada (ECCC) engaged the Canadian Institute of Climate Choices (Institute) to conduct an independent ssessment of the effectiveness of carbon pricing systems within the country. From the first engagement, it was made clear that the Institute would have the latitude to conduct its own independent assessment of federal, provincial, and territorial carbon pricing systems. ECCC initially consulted provinces, territories, and National Indigenous Organisations (NIOs) to define the scope of the assessment. The Institute adopted this scope and developed a work plan to conduct the research and a process to verify the findings.
