C.Scale determines the baseline from conservative assumptions representing a project in which no efforts have been made to reduce carbon emissions. The baseline provides a reference point for evaluating carbon reduction measures. * Baseline scenarios are **fully customizable.** * Baseline scenarios can be configured as **new construction, renovation or a combination of both**. * Baseline scenarios can be configured **to align with code**. * Baseline scenarios are flexible, and **any scenario can be tagged as the baseline**. ### Refining the Baseline In the left-hand panel, **select the scenario tagged "Baseline"**.

Baseline scenario selected in the left-hand panel.

After selecting the baseline scenario in the left-hand panel, the following warning will be displayed in the right-hand panel. The warning serves as a reminder that you are editing the baseline, which is used as the reference for all other scenarios.

Warning that the baseline is being edited.

The baseline can be refined using the [**Carbon Reduction Measures**](/users-guide/reduce-emissions.md) in the right-hand panel. ### Setting Another Scenario as the Baseline Any scenario within the project can be set as the baseline, and serve as the reference point for the project. To set another scenario as the baseline, click the **3-dot menu** to the right of the scenario name in the left-hand panel.

Click the 3-dot menu to set another scenario as the baseline.

Within the menu, click **Set as Baseline** to set another scenario as the reference for comparison.

### Analyzing the Baseline With the baseline scenario selected in the left-hand panel, analyze it using the following charts: * [Emissions Over Time](/users-guide/reduce-emissions/analyze-scenarios.md#emissions-over-time) * [Emissions by Scope Category](/users-guide/reduce-emissions/analyze-scenarios.md#emissions-by-scope-category) * [Emissions by Life Cycle Stage](/users-guide/reduce-emissions/analyze-scenarios.md#emissions-by-lca-stage) * [Emissions Summary](/users-guide/reduce-emissions/analyze-scenarios.md#emissions-summary) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.cscale.io/users-guide/create-a-project/set-a-baseline.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
