Response: NDCs – Nationally Determined Contributions

Home > Climate wiki > Response > Nationally Determined Contributions NDCs

Under the 2015 Paris Agreement (Article 4, paragraph 2) to reduce greenhouse gas emissions, 195 countries promised to set their own targets for reducing their emissions based on their circumstances. The self-regulating system was called Nationally Determine Contributions or NDCs. The goal was to keep the world well below 2°C; preferably no more than 1.5°C warming.

Figure 1 is Zealand’s submissions to the UNFCC in 2020. The target to reduce emissions is managed using an emissions budget—monetising emissions through the Emissions Trading Scheme—was one of the least ambitious on Earth (Fig. 2). The targets were supposed to include all sectors and all greenhouse gases. But many sectors were given exemptions including a 100% exemption on farming. But biogenic methane, i.e. methane from livestock is our largest greenhouse gas emissions by sector (Fig. 3).

New Zealand’s Paris Agreement target is inconsistent with the Government’s goal of keeping the average temperature increase to within 1.5°C, officials have told ministers. The advice from the Ministry for the Environment was given to Climate Change Minister James Shaw in February and obtained by Stuff under the Official Information Act. –  Stuff July 2020

In 2024 the Climate Change Commission published the first emissions reduction monitoring report. The report provided insight into the progress made, challenges experienced, and opportunities and risks that needed to be considered. In short, the country was not meeting it’s already abysmal emissions targets. During the webinar to present the report (Video 1) the Commissioner, Dr Rod Carr was asked:

What would happen if New Zealand wasn’t able or didn’t comply with our nationally determined contributions (NDCs)? What are the implications for us?

Reply:

When the rest of the world looks at New Zealand, if we haven’t met our national determine contributions—we won’t know on the 31st of December 2030 as it takes a couple of years for inventories and count up—but when the partners that we care about look at our behaviour and go, ‘Did you do all that you said you would? Did you do all that you said you would? And did you do all the things you could have done?’ That’s going to inform whether it’s ‘that you tried hard but missed’ or ‘you didn’t try’.

So foreign countries who are in incurring very real economic costs to reduce their emissions today—and that includes the Europeans, the Brits, and the Americans (there’s half a trillion U.S. dollars of taxpayers money being made available to reduce their emissions so the idea they’re not doing anything; that’s just wrong)—so when those countries look at NZ in the early 2030s and they look back to 2020, they go, ‘Well you could have made a better effort to, for example, decarbonized ground transport there were known technologies that were available, but you just chose to buy cheap high polluting cars. You could have chosen to stop burning as much coal and fossil gas to make electricity by investing more sooner in renewables, but you chose not to.’ I think that’s going to influence what the world thinks about New Zealand ‘s behaviour more than whether we did or did hit the exactnnumber of tonnes for this decade.

And the rest of the world looks at New Zealand and says, ‘You didn’t try. You didn’t take up the known technologies. You are short sighted, selfish, and reckless in your use of the climate for profit.’ I think their attitudes to us will be very different than if we had tried hard and done all we could but things didn’t turn out well. 

In January 2025 the Government submitted New Zealand’s second NDC climate target under the Paris Agreement. 

95% of countries miss UN deadline to submit 2035 climate pledges. ‘Just 13 of  the 195 parties published their new emissions-cutting plans, known as “nationally determined contributions” (NDCs), by the 10 February 2025 deadline…. The group has not yet analysed New Zealand’s NDC, but a climate expert within the country described it as ‘shockingly unambitious‘ – Carbon Brief 2025

Having failed to meet its commitments, the Minister for Climate Change Simon Watts stated: 

Claims that failure to meet Paris commitments would cost billions are baseless, Watts tells farmers: ‘It’s not a liability on our books, it’s intent and there is no legal obligation in the context around that.’ – Farmers Weekly 16 Feb. 2025

Government climate strategy: Let it burn. – Newsroom, November 2025

Those moves have rattled confidence in the emissions trading scheme, New Zealand’s main mechanism for driving private sector emission reductions. The price of NZU carbon credits has crashed from $88.50 in November 2022 to $39.75 at time of publication, a sign that investors doubt the government’s long-term commitment to the scheme. – The Spinoff, December 2025
