Issues Insufficient policy guidance on critical methodological issues: –Definitions (forest, deforestation, degradation) –Project and Baseline Emissions –Emissions from land-use after deforestation –Leakage (types, attribution, assessment) –Etc. Components of a baseline –Quantity –Location –Carbon stock changes

Applicability conditions (a)Only “gross deforestation”. (b)Deforestation agents, drivers and underlying causes can be identified. (c)Deforestation and forest degradation agents are bound to a certain region and cannot migrate beyond that region. (d)Information on forest cover and forest status before the start of the project activity is available for at least two points in time. (e)Information on land use-use and land-cover on deforested land before the start of the project activity is available.

Step 1. Define the boundaries of the proposed REDD project activity: spatial, temporal, carbon pools and sources of greenhouse gas emissions. Step 4. Project the quantity of future deforestation and forest degradation Step 3. Analyze agents, drivers and underlying causes of deforestation and forest degradation Step 5. Project the location of future deforestation and forest degradation by analyzing the spatial correlation between historical land-use and land-cover change and biogeophysical and socioeconomic factors (vicinity to roads, slope, population density, etc.) Step 7. Estimate the expected baseline carbon stock changes and non-CO 2 emissions. Step 2. Analyze historical land-use and land-cover change in the reference region during the past 10-15 years and project potential forest regeneration. Approach a: Linear projection. Deforestation and forest degradation are linearly projected from observed historical trends. Approach c: Corridor. Deforestation and forest degradation are projected as a likelihood corridor to reflect uncertainty. Step 6. Project future baseline activity data (the land-use and land-cover change component of the baseline) by combining the results of steps 2, 4 and 5. Step 10. Calculate the expected ex ante net anthropogenic GHG emission reductions. Step 8. Estimate the expected actual carbon stock changes and non-CO 2 emissions. Step 9. Estimate the expected leakage carbon stock changes and non-CO 2 emissions. Approach b: Multiple regression. Deforestation and forest degradation are projected using multiple regression.

Step 1. Define the boundaries of the proposed REDD project activity. 1.4 Sources of emissions and GHG Under the REDD activity scenario: GHG emissions that would occur in the baseline are avoided. GHG emissions due to project activities are likely to occur. GHG emissions due to leakage are likely to increase. Conservatively ignore them. Can count non-CO 2 emissions from forest fire. Reasonably assume that project emissions are less than baseline emissions ignore. Leakage prevention measures and activity displacement may lead to significant GHG emissions consider.

27
Step 4. Project the quantity of future deforestation and forest degradation 4.1Analysis of remaining forest area that is suitable for conversion to non-forest use and logging activities Time DD rates are likely to decrease once only “sub-optimal” areas remain available. DD rates should decrease once only “marginal” areas remain available. DD rates should be zero once no suitable area remains available. DD rates are likely to continue at the historical level as long as “optimal” areas are available. Ha yr -1

Step 4. Project the quantity of future deforestation and forest degradation 4.2Selection of the baseline approach (a)Linear projection: Future deforestation and degradation is linearly projected from past trends. (b)Modeling approach: Future deforestation and degradation is projected using multiple regression techniques (requires sufficient data points). (c)Corridor approach: Future deforestation and degradation is projected as an average of the historical rate. The 90% confidence interval of the mean is calculated to determine a “corridor” of likely baseline deforestation and forest degradation.

7.6Estimation of total baseline carbon stock changes and non-CO 2 emissions (C BASELINE )
47
Step 8. Estimate the expected actual carbon stock changes. Estimations are based on planned project activities. The expected level of “activity data” is reported in tables similar to the previous ones. The numbers of reduced activity data for “degradation” and “deforestation” and the underlying assumptions must be explained and justified. If specific measures are undertaken to enhance carbon stocks in “regeneration” forest classes, the Potential Forest Regeneration Map must be adjusted accordingly.
48
Step 9. Estimation of expected leakage: carbon stock changes and non-CO 2 emissions (C LEAKAGE ) E Displacement = (C BASELINE - C ACTUAL ) * X%
49
Assumptions about attributability of different types of leakage Attributable to a REDD project activity are: –Activity displacement. –Emissions from measures implemented to prevent activity displacement. Not attributable are: –Positive leakage (consistently with CDM). –Market effects: Project can not control markets and market actors, but government can Market effects are attributable to governments If market effects are not controlled by governments and carbon prices, DD will continue.
