Singapore's consumption-based footprint is 32.3 tonnes of CO₂ per person, ahead of Qatar. The United States, the country people expect on top, is #11 at 15.8 t, and China is #36. Consumption-based CO₂ counts goods people buy, including imports, so a trading hub ranks above the countries that make them.
