She said that the city's intense use of greenery with its numerous parks, gardens and nature reserves allowed carbon dioxide to be trapped and stored in the plants.
This was a sustainable solution for other cities to explore, she said.
'Singapore shows urbanisation does not damage the environment, when combined with environmentally friendly policies like the intense use of greenery and low motor usage here compared to other cities with similar income levels,' she said.
The report alluded to Singapore's success in this regard, but noted it did not take into consideration the amount of carbon dioxide produced by industry for products and services destined for foreign countries, including oil refineries and aviation.
The energy consumed in agriculture, in heat and light for residential buildings and power consumed by industry as well as transport were considered.
