For consistency with the CH4 and N2O sheets, the total amount incinerated should be reported here. However the fossil CO2 emissions from MSW should be reported either for total MSW or its components.

When a substantial quantity of waste in open dumps is burned, a relatively large part of waste is left unburned. In this situation, B frac should be estimated using survey or research data available or expert judgement.
