# Creating Custom Emission Factors

## Overview

In addition to standard [emission factors](https://support.lucanet.cloud/en/documentation/glossary.md#emission-factor) from our database, you can use custom emission factors to include missing or organization-specific data, ensuring that your results better reflect your organization's activities or specific supplier data.

Custom emission factors must first be created in the **Custom Emission Factors** workspace by an **ESG Administrator** before they can be used.

## Creating a Custom Emission Factor

To create a custom emission factor:

{% stepper %}
{% stepper-step %}
Navigate to the **Custom Emission Factors** workspace and click **Add custom factor**.
{% /stepper-step %}
{% stepper-step %}
In the **Create Custom Emission Factor** dialog, enter the required data.
{% /stepper-step %}
{% stepper-step %}
Click **Create** to save.

 The new custom emission factor will be displayed in the table as follows, for example:

'Custom Emission Factors' workspace

{% /stepper-step %}
{% /stepper %}
## Status of Custom Emission Factors

Custom emission factors can have two statuses: **In use** (actively used in the calculation of a footprint) and **Not used** (not currently referenced). The status is displayed in the custom emission factors overview as follows, for example:

Status of custom emission factors

Custom emission factors with the status **Not used** can be edited or deleted as needed.

## Exporting Custom Emission Factors

There are two options for exporting custom emission factors, including all their attributes, to a CSV file:

- Use the context menu opened by the three-dot icon next to each factor to download a single emission factor.
- Click **Export all** above the overview table to download all custom emission factors at once.
