Chapter 5 Estimation and uncertainty
This chapter sets out activity data and emission factor requirements and exemplifies statistical inference methods for their estimation using unbiased estimators consistent IPCC definition of good practice and for use in the methods outlined in Chapter 3. These methods remove the expectation of bias and quantify uncertainties. Methods for combining uncertainties to generate an overall uncertainty estimate are provided, building on IPCC guidance. Guiding principles given at the end of the chapter summarise aspects that may help a country decide on the combination of data sources and methods used to support reporting on GHG emissions and removals.
