# Set Project Strategy

### Create a new scenario

Scenarios are sets of carbon reduction measures that you define, analyze, and compare.

Click the **+ New Scenario** button to create a new scenario where you can apply carbon reduction measures. The new scenario includes all carbon reduction measures applied to the baseline. You can also duplicate an existing scenario to create a new one.

Name the new scenario and click **Create**.

With the newly created scenario selected in the left-hand panel, use the right-hand panel to begin applying carbon reduction measures, which are generally divided into the following categories:

* [**Reuse**](/users-guide/reduce-emissions/carbon-reduction-measures.md#reuse). These measures deal with the savings from reuse of existing building assemblies.
* [**Form and Massing**](/users-guide/reduce-emissions/carbon-reduction-measures.md#form-and-massing). These measures pertain to the impact the form of the building has on the amount of materials used in the structure and enclosure.
* [**Energy Use**](/users-guide/reduce-emissions/carbon-reduction-measures.md#energy-use). These measures pertain to reducing the use of energy in the building, and selecting clean sources of energy.
* [**Structure**](/users-guide/reduce-emissions/carbon-reduction-measures.md#structure). These measures pertain to selecting low carbon alternatives for the substructure and superstructure, including both lateral and gravity systems.
* [**Enclosure**](/users-guide/reduce-emissions/carbon-reduction-measures.md#enclosure). These measures pertain to selecting low carbon alternatives for the opaque enclosure, transparent enclosure, and roofing, and their replacement periods.
* [**Interior**](/users-guide/reduce-emissions/carbon-reduction-measures.md#interior). These measures pertain to selecting low carbon alternatives for the interior construction and fit-out, and their replacement periods.
* [**Services**](/users-guide/reduce-emissions/carbon-reduction-measures.md#services). These measures pertain to selecting low carbon alternatives for the mechanical, electrical, and plumbing (MEP) services and PV Array, and their replacement periods.
* [**Refrigerants**](/users-guide/reduce-emissions/carbon-reduction-measures.md#refrigerants). These measures pertain to selecting low carbon alternatives for the refrigerants used in building services (e.g., HVAC+R).
* [**Sitework**](/users-guide/reduce-emissions/carbon-reduction-measures.md#sitework). These measures pertain to the hardscape and landscape surrounding the building, and assess their respective potential to add or sequester carbon.
* [**Jobsite**](/users-guide/reduce-emissions/carbon-reduction-measures.md#jobsite). These measures pertain to the construction-related (A5) emissions.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.cscale.io/users-guide/reduce-emissions.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
