Climate change in Hong Kong

Averaged over the whole country, the last ten years (2016–2025) were 1.1 °C warmer than 1951–1980 according to Copernicus ERA5 — about as fast as the global average of 1.1 °C over the same period. Land areas warm faster than the oceans, so most countries warm faster than the global figure.

Climate models project Hong Kong to be about 1.3 °C warmer in 2040–2059 than in 1995–2014 under an intermediate scenario (SSP2-4.5; model range 1.0–1.8 °C), and 1.7 °C under very high emissions (SSP5-8.5).

Hong Kong emitted 33 million tonnes of CO₂ from fossil fuels and industry in 2024, 0.1% of the global total, or 4.5 tonnes per person — 95% of the world average. Historically it has emitted 0.1% of all CO₂ since 1750.
