Analysis
Hong Kong recorded 38.91 million tonnes of CO₂ equivalents for annual greenhouse gas emissions by world region in 2024.
The figure is up 0.9% on the previous year and down 23.3% over ten years.
Over the whole period, annual greenhouse gas emissions by world region in Hong Kong peaked at 50.72 million tonnes of CO₂ equivalents in 2014 and was at its lowest, 35,460 tonnes of CO₂ equivalents, in 1850.
Hong Kong ranks 111th of 199 countries on this measure, in the middle of the range.
The series is highly variable year to year, so single readings are best treated with caution.

About this data
Greenhouse gas emissions are measured in tonnes of carbon dioxide-equivalents over a 100-year timescale.
