For the Land Use Scenario:

1) Has the land-use designation for the area been changed?

For Other Scenarios:

2) Has the vegetation attribute [forest cover or carbon content-at maturity except for the Land Cover scenario] of the area passed a threshold [various possible definitions; or changed by more than a specified amount] since the last evaluation?

3) Is the activity that caused the crossing of the vegetation-attribute threshold an activity that results in the creation of ARD land (i.e., DHI)?

4) If the vegetation does not currently meet the criterion for forest, is it expected to grow past that threshold (all scenarios except Land Cover)?

For All Scenarios:

5) For ARD land where the ARD activity started before 2008: What was/is the carbon stock in the beginning of the commitment period? For ARD land where the ARD activity started after 1 January 2008: What was/is the carbon stock at the beginning of the activity (activity-based approach and land-based approach II)? What was/is the carbon stock at the beginning of the commitment period (land-based approach I)?

6) For ARD land: What is the carbon stock in the end of the commitment period?

7) Calculate carbon stock change as 2012 stocks from item 6 above minus [2008 stocks or pre-activity stocks] from item 5 above.

If the option of a D-R Rule and A/R Debit Rule is adopted, then:

8) For ARD land that was deforested between 1990 and 2007, limit credits from item 7 above to the extent by which the carbon stock in 2012 exceeds those [prior to deforestation or in 1990].

9) Limit any debit for afforestation and reforestation activities to credits received previously.
