Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In Taiwan, the incinerators process up to 16,693 tons of waste daily, and the greenhouse gas so emitted accounts for about 7.6% of all Taiwan greenhouse emissions. The study aims to provide a simple way to determine the average carbon dioxide emissions from eight municipal waste incinerators in Taiwan to aid in managing greenhouse gas emissions. The determination of carbon dioxide emissions is based on the lower heating value, the amount of electricity generated, as well as the content of carbon in waste incinerated. According to the resulting data from each incinerator, the finding of the study is that the carbon dioxide emission determined based on the content of carbon in waste incinerated is higher than that on lower heating value (wet basis) and that on amount of electricity generated. Another finding is that the resulting data is consistent to the original observations by each incineration plant. For a single incinerator, the conversion factors based on lower heating value is 0.772, and those based on the amount of electricity generated and the content of carbon in waste incinerated are 1.909 and 0.669 respectively. For a single incinerator, the mean absolute percentage error based on lower heating value is +0.017, and those based on the amount of electricity generated and the content of carton in waste incinerated are -0.029 and -0.030 respectively.
