Who emits the most CO₂, how that has changed, and each country's share of the all-time total…
Tracking who emits the most CO₂, how emissions have changed over time, and the cumulative burden each country carries - from the top annual emitters to per-capita rankings and all-time historical totals, for every country and region. Pick a place below for its own emissions, fuel mix and trend. Data from Our World in Data (Global Carbon Project).

Top Emitters
Top 10 Annual CO₂ Emitters
The top 10 countries produce over two-thirds of global annual CO₂ emissions. Source: Our World in Data – Global Carbon Project.
Top 10 Emitters Per Capita
Per-capita figures highlight small, fossil-fuel-rich nations - the biggest absolute emitters often rank lower here. Source: Our World in Data – Global Carbon Project.
Top 10 Cumulative CO₂ Emitters
CO₂ persists for centuries, so early-industrialised nations carry a disproportionate share of the total warming burden. Source: Our World in Data – Global Carbon Project.

Global Annual CO₂ Emissions
To limit warming to 1.5 °C, global emissions must roughly halve by 2030 and reach net zero by 2050. Source: Our World in Data – Global Carbon Project.
