International Carbon Allowance Trading

Interactive 3D simulation of linked emissions-trading systems: watch the EU, California and China carbon markets drift apart on their own fundamentals, then converge as you link them and allowances flow from the cheap market to the expensive one.

Compliance carbon markets rarely share one clearing price — the EU ETS, California's cap-and-trade and China's national scheme have each drifted to a wildly different price per tonne of CO₂, because each runs its own cap and its own demand curve. Linking systems together, as the Paris Agreement's Article 6 rules for cross-border trading allow, lets allowances flow from the cheapest market to the most expensive one until prices converge. This simulation lets you toggle which markets are linked and adjust cap tightening and demand growth to watch three independent carbon prices either drift apart or pull together.
