# 3.12. End of life of sold products

Scope 3.12: End-of-Life Treatment of Sold Products Calculation Engine 

The Scope 3.12 End-of-Life Treatment of Sold Products calculation engine enables you to calculate greenhouse gas (GHG) emissions arising from the processes involved in the end-of-life treatment of products sold by your organization. This engine is designed to track and report the indirect emissions generated during the disposal, recycling, or other treatment of products after they have reached the end of their useful life. Below is a guide on how to effectively use this calculation engine:

### **Data Entry Screen:**

* **Product Information** 
* **End-of-Life Processing Data** 
* **Emission Factors** 

**Calculation Engine** 

* **Data Collection:** 
  * The calculation engine aggregates all the data entered to compute the total emissions generated during the end-of-life treatment of the products. 
* **Emission Calculation:** 
  * Greenhouse gas emissions from the end-of-life treatment processes are calculated based on the energy and fuel used, and the corresponding emission factors. The engine reports emissions within the Scope 3.12 category. 
* **Reporting:** 
  * The calculated emissions are presented through detailed reports and graphs. These reports can be used to manage your organization’s Scope 3.12 emissions and to refine your sustainability strategies. 

**Best Practices:** 

* **Accurate Data Entry:** Ensure that all data regarding the end-of-life treatment processes are accurate and complete to guarantee the precision of the emission calculations. 
* **Detailed Processing Types:** Clearly define the processing methods (e.g., recycling, disposal) used for the end-of-life products to better understand the sources of emissions. 
* **Regular Monitoring:** Continuously monitor and update the emissions resulting from the end-of-life treatment of sold products to keep your reports current and relevant.
