Key Tips for an Accurate Carbon Footprint Estimation

Use Accurate, Site-Specific Data 📈

Reference Period: Data must be as precise as possible and represent a 12-month average period, as recent as possible (within the last two years).
Data Source: For example, energy consumption must come directly from your official records.
Quality Control: Review all data to ensure it is complete and relevant to obtain a high-quality analysis that meets Life Cycle Assessment (LCA) standards.

Responsibility for Entered Data ✅

You are responsible for the accuracy of all data entered into the CO₂ calculator.
ORIS cannot be held accountable for any erroneous or incomplete information you provide.

Comprehensive Accounting, Without Double Counting 🔍

Make sure to include all energy and material consumption related to the different stages of the production process.
Each emission source must be accounted for only once to ensure a reliable assessment.

Limit the Analysis to Aggregate Production 🚧

Only consider emissions directly related to aggregate production.
To be excluded from the calculation: energy and material consumption from administrative buildings or any other infrastructure not directly involved in production.

Definition of "Annual" Activities 📅

When you enter annual activities, only include those that occur every year or can be consistently annualized.
This includes regular maintenance activities or recurring operations essential for quarry operations.
Activities to exclude:
- Quarry opening or closure activities.
- Full equipment replacement with depreciation spread over more than three years.

Entering Values and Units ✍️

Decimal Separator: Always use the period (.) as the decimal separator (e.g., "3.25" instead of "3,25").
Quantity Unit: Quantities must be entered in tonnes (t). The unit symbol is 't' in the calculator.
