# Materiality Assessment — ESG Materiality Assessment

Enhances the materiality analysis capabilities of the esg-reporter and improvement-planner agents.

## Double Materiality

### Concept

```
Financial Materiality:
  ESG issue -> Impact on corporate value
  "Does this issue affect revenue, costs, or assets?"

Impact Materiality:
  Corporate activity -> Environmental/social impact
  "What is our business's impact on the environment/society?"

Double Materiality = Consider both financial + impact materiality
(CSRD/ESRS requirement)
```

## Materiality Assessment Process

### 5-Step Procedure

```
Step 1: Develop ESG Issue Pool
  - Reference GRI Standards topics
  - SASB industry-specific indicators
  - Competitor/peer benchmarking
  - Media/regulatory trends

Step 2: Identify Stakeholders
  - Internal: Management, employees, board
  - External: Investors, customers, supply chain, communities, regulators

Step 3: Assess Materiality
  - Stakeholder surveys/interviews
  - Expert panel evaluation
  - Data-driven analysis

Step 4: Build Matrix
  - X-axis: Business impact (financial materiality)
  - Y-axis: Stakeholder concern (impact materiality)
  - Plot issues -> Quadrant classification

Step 5: Validation and Approval
  - Management review/approval
  - Board reporting
  - External verification (optional)
```

## Materiality Matrix

```
Stakeholder Concern
High  +---------------+---------------+
      |  Monitor      |  Top Priority |
      |  (Enhance     |  (Strategic   |
      |   dialogue)   |   core)       |
      +---------------+---------------+
      |  Observe      |  Manage       |
      |  (Minimal     |  (Improvement |
      |   oversight)  |   plan)       |
Low   +---------------+---------------+
      Low        Business Impact     High
```

### Quadrant Response Strategies

| Top Priority | Carbon emissions, human rights, governance | Strategic integration, KPIs, reporting |
| Manage | Waste, supply chain | Improvement plans, monitoring |
| Monitor | Biodiversity, information security | Stakeholder dialogue, trend tracking |
| Observe | Certain philanthropic efforts | Minimal oversight |
