CSC Data Collection & Analysis 2 — Questions and Answers
Question 1: Which data collection method is most appropriate when quantifying a company's Scope 3 upstream emissions from purchased goods?
- Supplier-specific activity data with emission factors (Correct answer)
- Direct metering of facility energy consumption
- Employee commute surveys only
- Satellite imagery analysis
Correct answer: Supplier-specific activity data with emission factors
Scope 3 upstream emissions require supplier-specific activity data combined with relevant emission factors from databases like ecoinvent or EPA.
Question 2: A sustainability consultant is benchmarking water intensity across a manufacturing portfolio. Which normalization approach best enables cross-facility comparison?
- Water consumed per unit of production output (Correct answer)
- Total water withdrawn per facility
- Water discharged per employee
- Rainwater harvested per square foot
Correct answer: Water consumed per unit of production output
Normalizing water consumption by production output (intensity metric) removes scale differences and allows meaningful cross-facility benchmarking.
Question 3: Which statistical technique is most useful for identifying which ESG variables have the strongest predictive relationship with a company's financial performance?
- Multiple regression analysis (Correct answer)
- Simple frequency distribution
- Pie chart visualization
- Single-variable mean comparison
Correct answer: Multiple regression analysis
Multiple regression analysis can identify and quantify the predictive relationship between multiple ESG variables and a financial outcome variable.
Question 4: When a company uses the market-based method for Scope 2 GHG accounting, which data source takes highest priority?
- Contractual instruments such as renewable energy certificates (RECs) (Correct answer)
- National average grid emission factor
- Regional average emission factor
- Supplier's default emission factor
Correct answer: Contractual instruments such as renewable energy certificates (RECs)
The GHG Protocol's market-based Scope 2 hierarchy places contractual instruments like RECs at the top, reflecting the company's actual energy procurement choices.
Question 5: An analyst notices a sudden spike in a facility's monthly energy data. Before flagging it as a real increase, what should be the first verification step?
- Check for meter errors, billing anomalies, or reporting period mismatches (Correct answer)
- Immediately revise the annual GHG inventory
- Report the anomaly to regulators
- Remove the data point as an outlier
Correct answer: Check for meter errors, billing anomalies, or reporting period mismatches
Data quality requires verifying whether spikes are genuine operational changes or artifacts of measurement/reporting errors before taking action.
Question 6: Which ISO standard provides the framework for environmental performance indicators used in sustainability data collection?
- ISO 14031 (Correct answer)
- ISO 14001
- ISO 26000
- ISO 50001
Correct answer: ISO 14031
ISO 14031 specifically addresses environmental performance evaluation, including selection and use of environmental performance indicators.
Question 7: A consultant wants to assess biodiversity impact from a client's land use. Which data approach is most rigorous?
- Species richness surveys combined with habitat quality indices on-site (Correct answer)
- Carbon offset project registry data only
- Employee biodiversity awareness survey results
- Annual rainfall data from the nearest weather station
Correct answer: Species richness surveys combined with habitat quality indices on-site
On-site species richness surveys combined with habitat quality indices provide direct, site-specific biodiversity impact data required for rigorous assessment.
