Australia vs New Zealand
The gap between Australia and New Zealand is about ~8.2 tCO₂e/person/year per person per year (about 132% higher). Globally, Australia ranks around #3 and New Zealand around #21 by CO₂ per capita. Both can be compared to the global median of ~4.7 tCO₂e per person.

Quick comparison
Australia has higher per-capita emissions (~14.5 tCO₂e/person/year) than New Zealand (~6.2 tCO₂e/person/year). The difference is about ~8.2 tCO₂e/person/year, or about 132% higher.
In the global ranking by CO₂ per capita, Australia stands around #3 and New Zealand around #21.
Australia is above the global median (~4.7 tCO₂e/person), about 205% above.
New Zealand is above the global median (~4.7 tCO₂e/person), about 31% above.
Why the numbers can differ
GDP per capita often correlates with energy use: higher incomes tend to mean more transport, heating, and consumption. The relationship is not fixed—policy, energy mix, and urban design can decouple emissions from economic activity.
Urbanization affects transport patterns and building energy use. Denser cities can support public transit and district heating; sprawl tends to increase car dependency and per-capita emissions.
Electricity carbon intensity and the share of renewables in the power mix influence how much emissions drop when transport and heating electrify. Cleaner grids amplify the benefit of electric vehicles and heat pumps.
How to interpret per-capita vs total
Per-capita emissions divide a country's total CO₂ output by its population. That lets us compare nations fairly regardless of size. A large country with high total emissions can still have low per-person emissions if its population is very large. Total emissions matter for the global climate, but per-capita figures help us understand lifestyle and policy differences between countries.
What would move the gap
Targeted actions depend on each country's starting point. Levers that can narrow or reverse the gap include:
- Switching to renewable electricity and heat pumps for heating
- Phasing out coal and fossil gas in power generation
- Improving industrial process efficiency
- Improving building insulation and energy efficiency
- Expanding public transit and active mobility
- Shifting diets toward less carbon-intensive foods
- Reducing car use and choosing electric vehicles
- Reducing food waste along the supply chain
- Cutting down on air travel and long-haul freight
- Increasing renewable share in electricity generation

Frequently asked questions
Which country has higher CO2 per capita: Australia or New Zealand?
Australia has higher per-capita emissions (~14.5 tCO₂e/person/year) than New Zealand (~6.2 tCO₂e/person/year).
How do per-capita emissions differ from total emissions?
Per-capita emissions divide total national emissions by population, allowing fair comparison across countries of different sizes. Total emissions matter for global impact; per-capita figures help compare lifestyle and policy.
How does Australia compare to the global median?
About 205% above the global median of ~4.7 tCO₂e per person.
How does New Zealand compare to the global median?
About 31% above the global median of ~4.7 tCO₂e per person.
Does this include consumption-based emissions?
The main figure is territorial (production-based). We also show consumption-based CO₂ per capita when available, which counts emissions embedded in imported goods.
How often is this data updated?
