Trading platforms bring together supply and demand for emission allowances. In Europe, there are currently two large trading platforms on which emission allowances and their derivatives are traded: the German European Energy Exchange (EEX) and the British Intercontinental Exchange (ICE). The ICE unit that trades emission allowances is based in the Netherlands.
Trading in financial derivatives, such as futures of emission allowances, also takes place on the platforms. A future is a contract to deliver a certain quantity of emission allowances at an agreed point in the future at an agreed price. There are contracts for delivery in the short term or further into the future. These futures can be traded on the trading platform until shortly before the time of delivery. This does not require an account in the EU ETS Registry. When the contract end date has passed, the allowances are delivered through the EU ETS Registry and arrive in the account of the purchasing account holder. Without an account in the EU ETS Registry, delivery contracts cannot be met.
Like other trading platforms, the two platforms mentioned above are subject to admission requirements that may be a barrier for small issuers. On the other hand, trading platforms offer guarantees and assurances that deliveries and payments will take place.
