About these reports
The Commission has an important role in monitoring and reviewing Aotearoa New Zealand's progress towards its emissions reduction goals. This includes monitoring progress towards meeting emissions budgets, emissions reduction plans and the 2050 target.
We do this in two ways:
- An annual progress report
- A ‘periodic’ (end of an emissions budget) progress report – around every five years
About these reports
Our monitoring reports give people an independent assessment of whether Aotearoa New Zealand is on track to reach its goals. The Government and others can use this information to continually improve efforts to respond to climate change and smooth the transition to a low emissions future.
These reports are required under sections 5ZJ to 5ZL of the Climate Change Response Act 2002.
About the annual monitoring reports
Next due by 15 July 2026
The Commission provides an annual monitoring report that includes (for the most recent year of the emissions budget period for which data is available):
- measured emissions and removals for that year;
- the latest projections of current and future emissions and removals; and
- an assessment of the adequacy of the Government’s Emissions Reduction Plan and progress in its implementation, including any new opportunities to reduce emissions.
Reports are timed to follow the release of the New Zealand Greenhouse Gas Inventory report.
About the end of budget period monitoring reports
First due in 2027
The Commission will provide a report at the end of each emissions budget period (approximately every five years), evaluating progress made in an emissions budget period. These reports will include:
- an evaluation of how well the emissions reduction plan has contributed to progress;
- recommendations on any banking and borrowing across emissions budgets that would be appropriate; and
- an assessment of the amount of offshore mitigation required to meet the emissions budget for that period.
These less frequent reports must be prepared no later than two years after the end of the relevant emissions budget period. New Zealand’s first emissions budget covers the period 2022–2025, which means the first of these reports is expected to come out in 2027.
