Perform accuracy assessment to identify uncertainty in activity data.

Identify errors and conduct uncertainty analysis of ground observations used to generate emissions/removals factors.

Combine uncertainties to generate an uncertainty estimate for the REDD+ estimates.

Use key category analysis to identify priority areas to reduce uncertainty based on relative contribution to overall emissions.

Document identified errors, assumptions and approach applied in conducting the uncertainty analysis.

Establish approaches to reduce uncertainty and inform data collection and analysis processes.
