According to current knowledge, CO₂ produced by human activity is the biggest contributor to global warming. In 2024, the CO₂ concentration in the atmosphere was approximately 422 ppm, around 52% above the pre-industrial level (before 1750 = 278 ppm). Therefore, the consensus is that global average per capita CO₂ emissions must be reduced as quickly as possible from the current level of around 7.4 tons to less than 1 ton.

We have compiled the following facts and figures to give you a better idea of what 1 ton of CO₂ is and what this target means for humanity and for each individual:
