Expand `Emissions` in the left sidebar and open `Emission Factors` to create, publish, and edit factor sets. For how factors convert activity into carbon, see [Emission factors](/products/energ/concepts/emissions-accounting#emission-factors). ## Navigate to Emission Factors Click `Emissions` > `Emission Factors` in the portfolio left sidebar. Emissions Factor Library page with Search field, Filter button, Create Factor button, and table with Name Status Methodology Scope Service Type Country Region Grid Source and Created columns showing factors such as AIB EU Residual Mix and California Market Based Click `+ Create Factor` to open the **Create Factor Set** panel. Review the library table to check existing factors before you add or edit entries. For the column definitions in this table, see [emission factor fields](/products/energ/reference/emissions-reference#emission-factor-fields). ## Search and filter factors Use **Search** to find factors by name. Click `Filter` to show additional filters. Search field with Filter button and dropdown filters for Status Service Type Country Methodology and Effective date range with calendar icon | Filter | Purpose | | ------------------------ | ----------------------------------------------------------- | | **Status** | Show `Active`, `Draft`, or other statuses | | **Service Type** | Filter by commodity such as `Electric` or `Coal Anthracite` | | **Country** | Limit factors to one country | | **Methodology** | Filter by approach such as `Market Based` | | **Effective date range** | Show factors effective within a date window | Use pagination at the bottom to move through large libraries (for example, `1–50 of 139`). ## Publish or edit a factor Each factor row includes actions on the right side of the table. | Action | Purpose | | ----------------- | ------------------------------------------------------------------------ | | **Publish Draft** | Activate a factor in `Draft` status so it applies to carbon calculations | | **Edit** | Open the factor set to change details, documentation, or geography | | **Delete** | Remove the factor from the library | Emission factor table row actions showing Publish Draft tooltip on the publish icon, edit pencil icon, and delete trash icon for a draft factor dated 05/05/2026 Factors with **Active** status are already published. Click **Publish Draft** on draft rows (such as `California Market Based`) before you rely on them in emissions reports. ## Create a factor set Click `+ Create Factor` to open the **Create Factor Set** panel on the right. Create Factor Set side panel with Factor Name Description Organization Default checkbox Service Type Methodology and Scopes fields, Documentation section with Source Reference Provenance and Documentation Notes, and Close Add Factor Version and Save buttons Fill in **Factor Name**, **Service Type**, and **Scopes** (for example, Scope 2). Add **Description**, **Methodology**, and **Organization Default** when needed. Enter **Provenance** and optional **Source Reference** and **Documentation Notes**. Choose **Apply to Building** or **Apply geography wise**. When you apply geography wise, set **Country**, then **Region** and **Grid Code**, which activate after you select a country. Click `Add Factor Version` to add a version before you save, or click `Save` to store the factor set. Click `Close` to exit without saving. For the full list of factor set fields, see [emission factor fields](/products/energ/reference/emissions-reference#emission-factor-fields). Factors in `Draft` status do not affect production calculations until you activate them. Review draft entries before you rely on them in [Emissions overview](/products/energ/analytics/portfolio-emissions-overview) or [Benchmarking](/products/energ/analytics/portfolio-emissions-benchmarking). ## Next steps Understand how factors convert activity into carbon.
