GRI Data Collection & Measurement Techniques 3 — Questions and Answers
Question 1: When using supplier surveys to collect supply chain emissions data for Scope 3 Category 1, what is a key limitation GRI reporters must disclose?
- Surveys cannot be used for Scope 3 Category 1 under any circumstances
- Response rates may be low, leading to gaps filled with spend-based estimates (Correct answer)
- Supplier data is legally confidential and cannot be disclosed publicly
- Only Tier 1 suppliers are legally obligated to respond to surveys
Correct answer: Response rates may be low, leading to gaps filled with spend-based estimates
Low supplier survey response rates are a common limitation requiring gap-filling with secondary data, which must be disclosed as part of transparent reporting.
Question 2: Under GRI 303 (Water and Effluents), which measurement unit is required for reporting water withdrawal volumes?
- Gallons per day
- Cubic meters (megalitres acceptable) (Correct answer)
- Percentage of local watershed capacity
- Water intensity per unit of revenue
Correct answer: Cubic meters (megalitres acceptable)
GRI 303 requires water volumes to be reported in megalitres (ML) or cubic meters to ensure comparability across organizations.
Question 3: A manufacturing company uses different accounting software at each plant. What is the recommended GRI approach for ensuring data consistency?
- Select the plant with the best system as the reference and model others after it
- Implement a centralized data management system with standardized definitions (Correct answer)
- Report each plant separately with its own methodology
- Limit sustainability reporting to plants that share the same software
Correct answer: Implement a centralized data management system with standardized definitions
GRI's principle of comparability requires consistent definitions, methods, and systems across reporting units so data can be meaningfully aggregated.
Question 4: For energy consumption measurement under GRI 302, which conversion factor should be applied to fuel data?
- Lower heating value (LHV) as the default for most fuels (Correct answer)
- Higher heating value (HHV) as the only accepted standard
- An organization-specific factor derived from internal lab testing
- The conversion factor mandated by the local tax authority
Correct answer: Lower heating value (LHV) as the default for most fuels
GRI 302 recommends using lower heating values (LHV) as the default conversion factor for fuels, consistent with IEA and IPCC guidelines.
Question 5: An organization wants to report on employee training hours under GRI 404. Which employees should be included in the denominator when calculating average training hours?
- Only full-time permanent employees
- All employees including part-time, temporary, and seasonal workers (Correct answer)
- Employees who received at least one training session during the year
- Senior management and technical staff only
Correct answer: All employees including part-time, temporary, and seasonal workers
GRI 404 requires average training hours to be calculated across all employees regardless of contract type, ensuring full workforce representation.
Question 6: What does the GRI concept of 'materiality assessment' determine in the context of data collection?
- The financial thresholds for capitalizing sustainability investments
- Which topics are significant enough to require data collection and disclosure (Correct answer)
- The level of external assurance required for reported data
- The number of years of historical data that must be collected
Correct answer: Which topics are significant enough to require data collection and disclosure
A materiality assessment identifies economic, environmental, and social topics that reflect significant impacts, guiding which data must be collected and reported.
Question 7: When measuring diversity data for GRI 405, which demographic categories are required to be disclosed?
- Age and gender only, as these are universally measurable
- Gender identity, age group, and other indicators like minority or vulnerable groups where applicable (Correct answer)
- Ethnicity and nationality across all global operations
- Only categories required by local employment law in each jurisdiction
Correct answer: Gender identity, age group, and other indicators like minority or vulnerable groups where applicable
GRI 405 requires gender and age group as minimum disclosures, with additional indicators recommended where data is available and legally permissible.
