# Repository Structure

This document outlines the organization of the IFVI Value Factors repository.

## Overview

The repository contains value factors for converting environmental impacts into monetary terms, derived from the Global Value Factors Database (GVFD) released by the International Foundation for Valuing Impacts (IFVI).

## Data Organization for Policy and Governmental Users

The core-data directory is organized to facilitate use by policy makers and governmental actors:

1. **By Policy Domain**: 
   - Climate Policy: GHG emissions value factors
   - Air Quality Policy: Air pollution value factors
   - Land Use Policy: Land use and conversion value factors
   - Waste Management Policy: Waste value factors
   - Water Resource Policy: Water pollution and consumption value factors

2. **By Region**:
   - Continental regions
   - Economic zones (e.g., EU, OECD, G20)
   - Development status (e.g., developed, developing economies)

3. **By Impact Type**:
   - Health impacts
   - Ecosystem impacts
   - Economic impacts
   - Social impacts

4. **Aggregated Data**:
   - Complete datasets in multiple formats
   - Summary statistics and key indicators
   - Benchmark values for policy reference

## File Formats

- **JSON**: Primary data format, suitable for programmatic access
- **CSV**: Tabular format for spreadsheet applications and policy analysis
- **Parquet**: Columnar storage format for efficient querying and big data analysis
