The Government recently consulted on technical changes to emissions trading scheme and synthetic greenhouse gas levy regulations. 

Read our consultation document on proposed changes to NZ ETS and SGG levy regulations

The New Zealand Emissions Trading Scheme (NZ ETS) is a hugely important tool for Aotearoa’s efforts to reduce greenhouse gas emissions. 
It puts a price on emissions that encourages those who emit warming gases to reduce them by for example, investing in clean, climate-friendly technologies. 

To make sure the NZ ETS performs as well as it can to reduce emissions, its regulations are tweaked and updated every year. As part of that we wanted to hear from people interested or involved in the NZ ETS. Some of the changes are more significant this year – so it’s worth a look at the consultation if you’re involved in the scheme. 

The consultation included the following proposed changes to NZ ETS and SGG levy regulations:

  • Update unit limit and auction price control settings 
  • Update the default emissions factors (DEFs) for waste and natural gas fields, and update other DEFs and reference data to reflect new global warming potentials (GWPs) 
  • Update the electricity allocation factor used in industrial allocation 
  • Improve the methodology that accounts for waste in the NZ ETS 
  • Update the schedule of goods covered by the SGG levy 
  • Implement new regulations for an NZ ETS auction monitor
