New Zealand Emissions Trading Scheme
The New Zealand Emissions Trading Scheme (NZ ETS) is a partial-coverage all-free allocation uncapped highly internationally linked emissions trading scheme. The NZ ETS was first legislated in the Climate Change Response (Emissions Trading) Amendment Act 2008 in September 2008 under the Fifth Labour Government of New Zealand and then amended in November 2009 and in November 2012 by the Fifth National Government of New Zealand.The NZ ETS covers forestry (a net sink), energy (42% of total 2012 emissions), industry (7% of total 2012 emissions) and waste (5% of total 2012 emissions) but not pastoral agriculture (46% of 2012 total emissions). Participants in the NZ ETS must surrender one emission unit (either an international 'Kyoto' unit or a New Zealand-issued unit) for every two tonnes of carbon dioxide equivalent emissions reported or they may choose to buy NZ units from the government at a fixed price of NZ$25.Individual sectors of the economy have different entry dates when their obligations to report emissions and surrender emission units take effect. Forestry, which contributed net removals of 17.5 Mts of CO2e in 2010 (19% of NZ's 2008 emissions,) entered the NZ ETS on 1 January 2008. The stationary energy, industrial processes and liquid fossil fuel sectors entered the NZ ETS on 1 July 2010. The waste sector (landfill operators) entered on 1 January 2013. From November 2009, methane and nitrous oxide emissions from pastoral agriculture were scheduled to be included in the NZ ETS from 1 January 2015. However, agriculture was indefinitely excluded from the NZ ETS in 2013. The NZ ETS is highly linked to international carbon markets as it allows the importing of most of the Kyoto Protocol emission units. It also creates a specific domestic unit; the 'New Zealand Unit' (NZU), which will be issued by free allocation to emitters, with no auctions intended in the short term. Free allocation of NZUs will vary by sector. The commercial fishery sector (who are not participants) will receive a free allocation of units on a historic basis. Owners of pre-1990 forests will receive a fixed free allocation of units. Free allocation to emissions-intensive industry, will be provided on an output-intensity basis. For this sector, there is no set limit on the number of units that may be allocated. The number of units allocated to eligible emitters will be based on the average emissions per unit of output within a defined 'activity'. Bertram and Terry (2010, p 16) state that as the NZ ETS does not 'cap' emissions, the NZ ETS is not a cap and trade scheme as understood in the economics literature.Some stakeholders have criticized the New Zealand Emissions Trading Scheme for its generous free allocations of emission units and the lack of a carbon price signal (the Parliamentary Commissioner for the Environment), and for being ineffective in reducing emissions (Greenpeace Aotearoa New Zealand).The NZ ETS was reviewed in late 2011 by an independent panel, which reported to the public in September 2011. In response, the NZ ETS was amended in November 2012.
