Climate & Policy
New Zealand's climate targets, emissions profile, and the policy framework driving the transition.
Emissions Profile
Where NZ's greenhouse gas emissions come from
Emissions by Sector
By Greenhouse Gas
| Carbon dioxide (CO₂) | ~42% | Fossil fuels, industry |
| Methane (CH₄) | ~43% | Livestock, waste |
| Nitrous oxide (N₂O) | ~12% | Agriculture, fertilisers |
| F-gases | ~3% | Refrigeration, industry |
Trends Since 1990
- Gross emissions up ~14% since 1990
- Agriculture stable — livestock numbers declining but intensity up
- Transport up significantly — more vehicles, more driving
- Electricity down — more renewables, less gas/coal
- Forestry offsets — net emissions lower due to carbon sinks

Targets & Emissions Budgets
The legislative framework under the Zero Carbon Act
Emissions Budgets
| Budget Period | Budget (Mt CO₂-e) | Status | Reduction Plan |
|---|---|---|---|
| EB1: 2022-2025 | 290 | ✓ On track | ERP1 (May 2022) |
| EB2: 2026-2030 | 305 | ⚠ Moderate risk | ERP2 (Dec 2024) |
| EB3: 2031-2035 | 240 | ⚠ Significant risk | ERP3 (due 2029) |
The Zero Carbon Act (2019)
Amended the Climate Change Response Act 2002 to establish:
- Net zero by 2050 for all gases except biogenic methane
- Separate methane target (originally 24-47% reduction by 2050)
- Five-yearly emissions budgets as "stepping stones"
- Mandatory emissions reduction plans
- Independent Climate Change Commission
October 2025 Policy Changes
The current government has revised climate policy:
- Methane target reduced to 14-24% by 2050
- Agricultural emissions pricing delayed to 2030
- ETS reform underway (biennial settings)
- Carbon Neutral Government Programme target moved to 2050
- Focus on "technology-led" approach

NZ Emissions Trading Scheme
The primary policy tool for reducing emissions
How It Works
Emitters must surrender one NZU (New Zealand Unit) per tonne of CO₂-e emitted. NZUs can be:
- Purchased at auction — Government sells limited units
- Bought on secondary market — Trading between parties
- Received as free allocation — For emissions-intensive industries
- Earned from forestry — Trees absorbing carbon
What's Covered
| ✓ Fossil fuels (petrol, diesel, coal, gas) |
| ✓ Electricity generation |
| ✓ Industrial processes |
| ✓ Forestry (removals & deforestation) |
| ✓ Waste (landfill methane) |
| ✗ Agriculture (reporting only) |

Energy Transition Policy
The policy framework driving NZ's clean energy future
⚡ 100% Renewable Electricity
Aspirational target for 100% renewable electricity by 2030. Currently at ~85%. Focus now on "progress over perfection" — reaching 95%+ while maintaining affordability.
Target: 2030🔋 50% Renewable Energy
Target for 50% of total final energy consumption from renewables by 2035. Requires electrification of transport and industrial heat.
Target: 2035🚗 Clean Car Standard
CO₂ emissions standards for imported vehicles (new and used). Targets average 112g/km by 2027. Clean Car Discount scheme ended in 2024.
✓ Active🏭 GIDI Fund
Government Investment in Decarbonising Industry — co-funding for businesses to switch from coal/gas to electricity or biomass for process heat.
✓ Active🌬️ Offshore Wind Framework
Developing regulatory framework for offshore renewable energy. NZ has world-class offshore wind potential. Consenting framework expected 2025.
⚠ In development🔥 Gas Transition Plan
Managing decline of natural gas while maintaining energy security. Includes exploring LNG imports and supporting alternative fuels (biogas, hydrogen).
⚠ In developmentKey Energy Targets
| Target | Deadline | Current | Status |
|---|---|---|---|
| 90% renewable electricity | 2025 | ~85% | ⚠ Close |
| 100% renewable electricity | 2030 (aspirational) | ~85% | ⚠ Challenging |
| 50% total energy renewable | 2035 | ~40% | ⚠ Needs acceleration |
| Government fleet carbon neutral | 2050 (revised from 2025) | — | Delayed |
