Now, as we know, good Governments should seek to play a facilitative role in markets to help create and shape markets, as well as provide the framework within which these markets operate. This bill does exactly that for emissions. For a start, we're moving away from the scheme's $25 fixed price options for emissions units. This was always meant to be temporary, but it has ended up as an artificially low ceiling on the cost of emissions. What it will be replaced with is both a price floor and a cost containment reserve. Working in tandem, these mechanisms will stop the price of emissions either getting too low or too high. In effect, then, the gap between them, between the lowest price an emissions unit can drop to and triggering of the cost containment reserve, is where the market will operate.
