# 3.11. Use of Sold Products

Scope 3.11: Use of Sold Products Calculation Engine 

The Scope 3.11 Use of Sold Products calculation engine enables you to quantify the greenhouse gas (GHG) emissions generated during the use of your sold products by customers or end users. This tool is essential for tracking and reporting the indirect emissions that occur throughout the product's lifecycle during its usage. Below is a guide to help you effectively utilize this calculation engine:

### **Data Entry Screen:**

* **Product Information:**
* **Usage Process Data:** 
* **Emission Factors:**
  * **Emission Factors:** The system automatically applies emission factors based on the selected energy type and usage process data. These factors are sourced from reliable institutions such as IPCC and DEFRA and can be adjusted to reflect the region where the product is used.

**Calculation Engine:**

* **Data Aggregation:**
  * The calculation engine aggregates all the entered data to compute the total emissions generated during the product's usage phase.
* **Emission Calculation:**
  * Greenhouse gas emissions are calculated based on the energy and fuel consumed during the product's lifecycle. The calculations are performed using the predefined emission factors, and the results are reported as Scope 3.11 emissions.
* **Reporting:**
  * The calculated emissions are presented in detailed reports and graphs. These outputs are valuable for managing your organization's Scope 3.11 emissions and refining your sustainability strategies.

**Best Practices:**

* **Data Accuracy:** Ensure that all data related to the product’s usage phase is accurate and complete. Accurate data entry enhances the reliability of the calculations.
* **Comprehensive Product Analysis:** Conduct a thorough analysis of energy consumption and emissions throughout the product’s lifecycle.
* **Continuous Monitoring:** Regularly monitor and report the emissions resulting from the use of sold products to maintain up-to-date records.
