Understanding your emissions

The average carbon dioxide (CO₂) emitted by an individual’s daily activities varies widely across the globe. This is due to differences determined by:

• Climate and varying seasons;

• Development stage of a country;

• National resources and energy mix;

• Available transportation systems;

• Government regulations;

• Varying standards of living.

To illustrate how these factors translate into different carbon emission brackets, let us review select statistics from Our World in Data’s Per capita CO₂ emissions report:

Annual CO₂ emissions (per capita), tonnes per person

These figures highlight significant differences between continents, shaped by varying consumption patterns and efficiency levels. Looking deeper into the report, which presents per-capita emissions by country, it becomes possible to derive estimated emission ranges for individuals and organizations.

Understanding these reference values is important. Calculating precise personal or corporate CO₂ footprints can be time-consuming, costly, and complex. At Tree-Nation, we therefore support and encourage the use of emission estimates as a practical starting point for climate action, for three key reasons:

Accessibility

Average emission figures are easy to understand, widely available, and do not require specialized expertise. They provide a clear reference point that individuals and companies can use to contextualize their climate impact and define meaningful climate contributions.

Fairness

Average emissions vary significantly between countries and regions, with higher-income economies generally emitting more CO₂ per capita. Using regional and national averages helps reflect these differences and encourages those with higher emissions to take proportionate responsibility in supporting climate action.

Collective responsibility

Climate change is driven by cumulative global emissions. While emission levels differ across countries and individuals, addressing climate change requires participation at every level. Emission estimates help frame this challenge collectively and encourage action that contributes to broader climate and ecosystem solutions.
