What Is the Average Carbon Footprint by Country?

The global average carbon footprint is roughly 4.7 tonnes of CO₂ per person each year, but national averages stretch from under 1 tonne to more than 15. Wealth, energy mix and the way each country counts its emissions all move the figure, so treat any single number as a well-informed estimate rather than a fixed fact. The gap between the highest and lowest emitters is more than twentyfold, which is why one global average hides as much as it reveals.

Average carbon footprint by country

• United States ≈ 14–15 t. High car dependence, large detached homes and heavy energy use keep per-person emissions among the highest of any large economy.
• Australia ≈ 15 t. A coal-heavy electricity grid and long travel distances push it to a similar level, and some estimates rank it above the US.
• China ≈ 8 t. Now clearly above the global average, driven by manufacturing and coal power, though still only about half the US figure per person.
• United Kingdom ≈ 5 t. Close to the world average after two decades of switching from coal to gas, wind and imports.
• India ≈ 2 t, many African nations under 1 t. Lower incomes and less energy-intensive lifestyles keep footprints small despite very large populations.

Territorial vs consumption: why imports change the picture

Most headline figures use territorial accounting — the emissions produced inside a country's borders. A consumption-based count instead adds the emissions embedded in imported goods and subtracts those in exports, and it can lift a wealthy nation's footprint by 10–40% because that country has effectively outsourced its factory emissions overseas. This is why the UK and much of Western Europe look cleaner on paper than the products their residents actually buy, while big manufacturing exporters like China carry emissions for goods consumed elsewhere. To see where you personally sit against these averages, the free Evertreen CO₂ calculator gives a quick, consumption-style estimate in a couple of minutes.

Why the numbers differ so much

Three factors explain most of the gap. First, energy mix: a grid built on coal emits far more per kilowatt-hour than one built on hydro, nuclear or wind, so two equally wealthy countries can differ sharply. Second, wealth and consumption: richer populations fly more, drive more and heat larger homes. Third, transport and density: sprawling, car-dependent nations burn more fuel than compact ones with strong public transit. Because sources and years disagree — the International Energy Agency, Our World in Data and national inventories each use slightly different methods — a given country's figure can shift by a tonne or more depending on which dataset you read.

How to find, cut and offset your own number

Start by measuring, then reduce the big levers — flights, driving, home heating and diet — before offsetting whatever is left. Evertreen keeps that final step transparent: you can plant real, geolocated trees from £1.5 each through our tree-planting projects, and every tree is tracked with GPS coordinates and photos so you can see exactly what your contribution funded. We are also open about the science behind the benefit — our page on how we estimate tree CO₂ sets out the assumptions and typical per-tree sequestration ranges, so planting complements genuine cuts rather than excusing them.

Frequently asked questions

What is the average carbon footprint per person? Globally it is around 4.7 tonnes of CO₂ per person per year, though estimates vary with the source, the year and whether imported goods are counted.

Which country has the highest carbon footprint per person? Among large economies the United States and Australia sit near the top at roughly 14–15 tonnes per person, while several small oil-producing states such as Qatar are higher still.

How many trees offset one person's carbon footprint? A mature tree may absorb roughly 20–25 kg of CO₂ a year, so offsetting a 5-tonne footprint could take a few hundred trees over their lifetime — a useful guide rather than an exact figure.
