The Environment & Ecology Bureau today released the 2024 greenhouse gas (GHG) emission inventory for Hong Kong.

Hong Kong’s total GHG emissions in 2024 amounted to about 33.2 million tonnes of carbon dioxide equivalent (CO2-e), representing a decline of about 3.6% compared with 2023 levels and a decrease of about 27% from the peak emissions in 2014.

Per capita GHG emissions reached a new low of 4.41 tonnes in 2024, 3.5% lower than the previous year. The emissions were about one-quarter of the US level and 60% of the European Union amount.

Carbon intensity in 2024 was 0.011kg CO2-e per Hong Kong dollar of GDP, about 6% lower than in 2023.

Electricity generation continued to be the largest source of emissions, generating 61% of total emissions in 2024. Other major emission sources were transport, accounting for 18% of the total, and waste management, which accounted for 8%.
