# Calculated Metrics (Biogenic Emissions)

## Understanding Biogenic Emission Corrections in 2050-Materials Platform

### Overview

The 2050-Materials platform employs a process to update our material data (`MaterialFact` model) based on calculated biogenic emissions. This is crucial for accurately reflecting the carbon footprint of materials, especially those with significant biogenic content.

### The Correction Process

#### Key Points

* **Biogenic Emissions**: These are emissions associated with biogenic materials like wood. They're factored into the total and manufacturing CO2e (Carbon Dioxide Equivalent) values.
* **Fields Updated**: The process corrects fields like total biogenic CO2e, manufacturing emissions, end-of-life emissions, and total CO2e for the material.

#### Steps Involved

1. **Biogenic Material Percentage**: The system first checks the percentage of biogenic material by weight.
2. **Scaling Factor**: It retrieves a scaling factor to convert the declared unit to kilograms, essential for accurate corrections.
3. **Calculation**: Biogenic emissions are calculated based on the biogenic material percentage and scaling factor.
4. **Conditional Corrections**: Corrections are applied to manufacturing, end-of-life, and total CO2e emissions based on specific conditions.
5. **Updates**: The `MaterialFact` instance is updated with new corrected values.

### Importance of Biogenic Emission Corrections

Correcting for biogenic emissions is vital in providing a more accurate representation of a material's carbon footprint. This process helps ensure our platform delivers reliable and comprehensive environmental data.
