Debates over the Pan-Canadian Framework on Clean Growth and Climate Change are almost universally framed in economic or constitutional language — carbon tax rates, provincial autonomy, and judicial division of powers under section 91(POGG) of the Constitution Act.
Yet when examining Nova Scotia’s Output-Based Pricing System (OBPS) alongside the federal backstop at the Johnson Shoyama Graduate School of Public Policy, what struck me was how much of carbon federalism is fundamentally an information architecture problem.
Inter-jurisdictional data asymmetry
Provincial industrial compliance relies on facility-level emissions reporting that feeds into provincial environmental databases. But federal equivalency reviews under the Greenhouse Gas Pollution Pricing Act (GGPPA) require verifiable, standardized data metrics that can be audited by federal analysts.
When systems do not share semantic standards or measurement cadences, policy debates get bogged down in reconciliations between differing data models rather than environmental efficacy.
Designing transparent emissions ledgers
To achieve genuine environmental accountability, intergovernmental agreements must treat emissions registries as shared, auditable information infrastructures. Without high-fidelity data governance, emissions trading benchmarks remain vulnerable to administrative arbitrage.
