- Its headcount at each site
- Its ownership percentage in each operation (Correct answer)
- Its financial control over the entity
- Its operational control over the facility
Correct answer: Its ownership percentage in each operation
Under the equity share approach, a company reports its share of emissions from operations in proportion to its ownership stake.
Question 15: What is 'additionality' in carbon offsetting?
- A method for calculating combined Scope 1 and Scope 2 emissions
- The additional cost of purchasing carbon offsets above market price
- The requirement that an offset project achieves reductions that would not have occurred without the carbon credit incentive (Correct answer)
- The process of adding more carbon credits to a registry
Correct answer: The requirement that an offset project achieves reductions that would not have occurred without the carbon credit incentive
Additionality ensures that offset projects deliver genuine emission reductions beyond what would have happened under a business-as-usual scenario.
Question 16: Which principle requires that a GHG inventory include all emission sources within the defined boundary, avoiding selective exclusion of inconvenient sources?
