Due to the geographical characteristics of Macao, there are only emissions from energy activities and waste disposal within its administrative division. In 2010, Macaos total greenhouse gas emissions were 1.193 million tons of carbon dioxide equivalent (see Table 8-2 and Table 8-3), of which energy activity emissions accounted for 98.3% of the total emissions, and waste disposal emissions accounted for 1.7% of the total emissions (See Figure 8-1). In 2010, the total greenhouse gas emissions in Macao were about 1.159 million tons of carbon dioxide, accounting for about 97.2% of the total emissions; methane was about 4,000 tons of carbon dioxide equivalent, accounting for about 0.3% of the total emissions; nitrous oxide was about 30,000 tons tons of carbon dioxide equivalent, accounting for about 2.5% of the total emissions (see Figure 8-2).
