From July 2015, the Australian federal government will set the price of the permits in its emissions trading scheme free – within limits. The government intends to introduce a price floor and price ceiling until at least 2017/18.
This is good news for emission reduction activities whose viability depends on prices several years hence, such as larger, more complex projects. Further, the goal of abatement at least-cost should be balanced against the goal of abating as rapidly as possible; should reaching current targets be cheaper than expected, a floor price can ensure a minimum level of spending on abatement.
Last December, the government released a discussion paper and called for submission on the price floor, which combines a reserve price for Australian carbon units at auction with an ‘international unit surrender charge’ that ensures international carbon credits cost at least as much as domestic units. Four options are being considered for the international unit surrender charge.
