# Scenarios

## Available Scenarios

PACTA as a methodology is scenario agnostic, however the methodology requires data with sufficient technological and regional breakdowns; i.e. it should cover the same sectors and ideally provide pathways at a country or regional granularity. 

The table below gives an overview of available scenarios in the for Investors tool. 

| **Scenario**                              | **Sectors Covered**                                 | **Global Average Temperature rise in 2100** | **Probability**    | **Publication**                                                  | **Abbreviation**       |
