1. What's a scenario?
They allow you to simulate your carbon strategy by applying different actions (with different dates and levels of application).
Pro tip: an existing scenario can be duplicated and used as the basis for another scenario.
2. Case 1: compare different categories of actions
Let's take the example of a company that wants to see the impact of actions focused solely on its energy consumption: it then selects actions in this category (insulating its buildings, replacing its gas heating with a heat pump, reducing the use of air conditioning, etc.). On the other hand, if you're wondering about the impact of an action plan focused on transport, you create a scenario containing actions such as carpooling, favoring train travel over air travel, etc.
You can then compare the trajectories of the different scenarios and choose the one that seems most relevant.
3. Case 2: compare different levels of ambition
Another use case is the comparison of different ambitions: to do this, you can select actions in a first scenario, then duplicate it and increase or decrease the level of application of the actions. This way, you'll know at what level your actions will achieve your objectives!
