# 3.13. Downstream Leased Assets

Scope 3.13 Downstream Leased Assets Calculation Engine - Help Page

The Scope 3.13 Downstream Leased Assets calculation engine allows you to calculate the greenhouse gas (GHG) emissions generated from the use of assets that are leased by your company to customers. This engine is designed to track and report the indirect emissions that occur throughout the lifecycle of these leased assets. Below is a guide on how to effectively use this calculation engine:

### **Data Entry Screen:**

**Asset Information:** 

* **Usage Duration:** Specify the duration for which the asset has been leased to the customer. This information can be entered in months or years.

**Energy and Fuel Usage:**

* **Energy Consumption:** Enter the amount of energy consumed during the use of the leased assets (measured in kWh or MJ). 
* **Fuel Consumption:** Input the amount of fuel consumed during the asset’s use (measured in liters or kilograms). This could include, for example, the fuel used by leased vehicles.

**Emission Factors:**

* **Emission Factors:** Emission factors are automatically applied based on the type of asset and the types of energy or fuel used. These factors are sourced from reliable organizations such as IPCC and DEFRA and can be adjusted to reflect regional or national standards.

### **Calculation Engine:**

**Data Aggregation:**

* The calculation engine aggregates all entered data and calculates the total emissions generated from the use of the leased assets.

### **Emission Calculation:**

* Greenhouse gas emissions are calculated based on the energy and fuel consumption during the asset's usage period. The calculations are based on the specified emission factors and report the total Scope 3.13 emissions.

### **Reporting:**

* The calculated emissions are presented in detailed reports and graphical formats. These reports can be used to manage your organization's Scope 3.13 emissions and to develop and refine your sustainability strategies.

### **Best Practices:**

* **Accurate Data Entry:** Ensure that the data related to the use of leased assets is accurate and complete. Accurate data entry will improve the reliability of the calculations.
* **Detailed Asset Usage Analysis:** Conduct a thorough analysis of the energy and fuel consumption associated with the leased assets.
* **Ongoing Monitoring:** Regularly monitor the emissions generated from downstream leased assets and keep your reports up to date.
