Greece vs Slovakia
Greece emits more CO₂ per capita than Slovakia by about ~0.0 tCO₂e/person/year (about 1% higher). Globally, Greece ranks around #25 and Slovakia around #27 by CO₂ per capita. Both can be compared to the global median of ~4.7 tCO₂e per person.

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:
- Supporting policies that phase out fossil fuels
- Ensuring new infrastructure is low-carbon from the start
- Expanding clean energy access without locking in fossil dependency
- Avoiding high-emission development pathways
- Building resilience while keeping emissions low

Frequently asked questions
Which country has higher CO2 per capita: Greece or Slovakia?
Greece has higher per-capita emissions (~5.3 tCO₂e/person/year) than Slovakia (~5.3 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 Greece compare to the global median?
About 12% above the global median of ~4.7 tCO₂e per person.
How does Slovakia compare to the global median?
About 11% 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?
Data comes from Our World in Data, World Bank, and Ember. Coverage and latest year vary by metric.
