HOW IT WORKS

Five steps from cap to compliance

Every game runs the same loop a real emissions trading system does — you make the decisions, the market sets the price.

  1. 01

    Receive your cap

    Each firm starts with a compliance obligation — an absolute allowance budget under cap-and-trade, or an emissions-intensity benchmark per unit of output under an intensity-based system.

  2. 02

    Choose abatement investments

    Read your marginal abatement cost curve and decide which emission cuts are worth funding, working from the cheapest tonnes upward.

  3. 03

    Trade allowances

    Buy or sell allowances with other firms on a live order book whenever the market price diverges from your own cost of abating a tonne.

  4. 04

    Watch prices emerge

    A continuous double auction turns every firm’s decisions into a clearing price — supply and demand discovered in real time, not assumed.

  5. 05

    Analyze the outcome

    At period end, settle against your cap: surrender allowances, bank surpluses, or pay penalties — then review profits, emissions, and compliance.
