Carbon Markets & Border Mechanisms
How pricing and border measures interact, technically and procedurally, across trading partners.
Study time: 60 min
By the end of this module you can
- Trace how an instrument's scope, benchmarks and thresholds operate
- Follow how carbon costs are recognised between systems
- Read a compliance timeline and its obligations accurately
Overview
Carbon pricing does not stop at a border, and border measures do not work without pricing behind them. This module reads the two together: how an instrument's scope, benchmarks and thresholds actually operate, how carbon costs are recognised between systems, and how to read a compliance timeline for the obligations it really imposes. It works across the compliance systems in the tracked set, comparing how different jurisdictions structure scope, benchmarks and the recognition of carbon costs.
Exercise
Pick one system from the tracked set. List, in order, the compliance steps it imposes on a covered entity.
Explain in three sentences how a carbon cost paid in one system is recognised (or not) in another.

Leakage is the concept that links carbon pricing to trade policy, and the usual justification for free allocation or border adjustments.
