The results of the survey are extrapolated to match the number of employees declared in the "Company Information" page.
This means we do not specifically extrapolate the answers of your company's employees.
Methodology for Extrapolating Employee Emissions
Purpose: To estimate GHG emissions for employees who do not respond to the annual survey, ensuring a complete and accurate carbon inventory.
Foundation: Calculations are based on a standard work profile derived from survey averages.
Number of effective workdays per year: 222.5
Number of remote days per week: 1.7
Behavioral Data: The activity profile (commuting, meals, energy use) is based on average results from a survey of French employees.
→ It's a mix of employees who have answered the Greenly survey (all employees, not just French) and Greenly assumptions based on studies (mostly French studies but also EU studies).
Application: This standardized activity data is applied globally to all non-respondents.
Localization: Final emissions are calculated using country-specific emission factors to ensure geographic accuracy.
Guiding Principle: The methodology uses conservative assumptions to prevent the under-reporting of emissions.
Hypotheses by Category:
Meals
The following average weekly diet from survey data (e.g., occurrences of vegan, red meat meals) is applied to non-respondents.
Number of Vegan meals: 0.29
Number of Vegetarian meals: 1.41
Number of Fish meals: 0.71
Number of White Meat meals: 1.64
Number of Red Meat meals: 0.95
→ Total: 5 meals
This baseline is validated against external benchmarks such as ADEME data to ensure it is representative.
Home Office Heating
A conservative approach is used, assuming 100% of non-respondents use the most carbon-intensive heating fuel available: fuel oil.
This is applied to the average home office surface area (12.8 m²) and a conservative heating temperature (21°C).
Home Office Air Conditioning
A conservative assumption of 100% usage is applied to non-respondents to avoid underestimation.
Calculations use the average cooled surface area (12.8 m²) and temperature (23.0°C) from survey data.
Commuting
The number of commuting days is derived from the work profile (5 workdays - 1.7 remote days ≈ 3 commute days per week).
A standard, multi-modal weekly travel scenario is applied per employee.
1 day by electric bike (10 km)
1 day by public transport (20 km)
1 day by car (20 km)
Car Assumptions (Conservative Approach):
Vehicle Type: Sedan with a diesel engine. This reflects a common vehicle type from past surveys and is a conservative choice for emissions.
Carpooling: The carpooling percentage is set to 0% to ensure a conservative calculation.
These weekly distances are scaled to an annual total per non-respondent to determine total emissions.
