Table 4 Summary of IPCC data categories for Activity Data on forest area changes and Emission Factors for changes in carbon stocks from deforestation and forest degradation.
Approaches for Activity Data: Forest Area Changes | Tiers for Emission Factors: Changes in Carbon Stocks |
|---|---|
1. Non-spatial country statistics | 1. IPCC default values by continent and forest type |
2. Maps, surveys, and other national statistical data | 2. Country specific data for key factors |
3.Spatially explicit data from interpretation of remote sensing imagery | 3.National inventory of carbon stocks, via repeated measurements of key stocks through time or modeling |
