Singapore's Emissions Profile

Find out more details on Singapore's emissions profile.

Last updated 30 July 2026

Climate change is a global challenge that requires a global response. Despite the unique challenges and constraints Singapore faces as a densely built-up city-state with no hinterland and limited resources, we are committed to doing our part in the global fight against climate change.

Historically, our strategic position along the East-West trade routes has made Singapore a natural location for oil storage and refining facilities serving the region. Building on our position as a key regional port, the refining and petrochemical sector helps create synergies and is part of a business supply network in Southeast Asia, the Western Pacific, South Asia and Australasia. Although the refining and petrochemical sector remains a significant proportion of our total carbon emissions, we are taking steps to reduce emissions.

Emissions Profile

Carbon Intensity (CO2 per $GDP)

Singapore performs well in terms of carbon intensity globally (164th out of 195 countries/territories for CO2 emissions per dollar GDP PPP in 2023, with the 1st having the highest carbon intensity).1
