🇳🇺 Niue's Greenhouse Gas Emissions

Key Messages

• Emissions: Niue emitted around 0.01 megatonnes CO₂e in 2024, effectively 0% of the global total.
• Per person: Emissions were around 4.8 tonnes per person per year in 2024, rated moderate on a scale where any level above zero adds warming.
• Trend: Emissions fell by around 1.44% a year over the ten years to 2024, slower than the 4% yearly global decline needed for Net Zero in 2050 and warming of around 1.7 °C.
• What drives it: CO₂ makes up 80.2% of emissions, methane 16.1%, nitrous oxide 3.69% and F-gases 0%.
• Historic responsibility: Since 1851, Niue's emissions have produced around 0.9 megatonnes CO₂e of warming impact, 0% of the global total, or around 3.8 tonnes per person per year on a population-weighted basis.
