# IOOI analysis -based monetization
## Introduction
Upright conducts IOOI (Input, Output, Outcome, Impact) based monetization with the following two-step process:
1. **Impact pathway analysis**: The IOOI (Input, Output, Outcome, Impact) framework is applied to scope relevant *inputs* and *outputs*, and their consequences as *outcomes* and *impacts*.
2. **Monetization**: Impacts are monetized using monetization factors corresponding to the impacts defined in the impact pathway analysis.
## Example (GHG emissions)
We will demonstrate this monetization approach using *harms caused by human-emitted carbon emissions* as an example.
**Figure 1** summarizes forms of carbon emissions along with their consequences using the structure provided by the IOOI framework.
Figure 1: Summary of the IOOI analysis conducted for costs related to GHG emissions
The monetization factor Upright uses for CO2 equivalent emissions is 417 USD per CO2 tonne, based on [*Ricke, K., Drouet, L., Caldeira, K. et al. Country-level social cost of carbon. Nature Clim Change 8, 895–900 (2018)*](https://doi.org/10.1038/s41558-018-0282-y)*.*

**Background on the cost of carbon figure used by Upright**
Upright has used the cost of 417 USD per CO2 tonne since 2018, when the *Ricke et al.* paper was published.
While there has been an abundance of new research published since that, it has not provided a compelling reason to update the figure, as the 417 USD figure falls well into the (published) margins of error of also newer mainstream research, or simply reflects a slight change in assumptions, such as discount rate ([as in this article](https://doi.org/10.1038/s41586-022-05224-9)).

**IOOI outputs vs impacts**
In the IOOI framework, Carbon emissions — as well as several other commonly measured impacts — are considered "outputs" rather than "impacts".
Upright uses IOOI analysis to translate outputs — like emissions — and direct impacts — like Meaning & Joy — to a common class of impacts that can be monetized consistently.
