Uncertainty in REDD+ carbon accounting: a survey of experts involved in REDD+ reporting

Table 1 Levels of reporting, experience, and importance for improvement for sources of error related to uncertainty of emission factors and activity data in REDD+ reporting. Uncertainties in activity data were not disaggregated into multiple sources because a vast majority of countries report only sampling error for activity data
