How do I know which materials are supported?

You can use the `get_material_registry` tool to retrieve a complete list of all materials currently in the system along with their specific emission factors.

Can I calculate savings for multiple materials at once?

Yes, the `calculate_batch_recycling_impact` tool allows you to provide a JSON array of items to calculate cumulative CO2 savings for an entire batch.

How is the environmental impact tier determined?

The `get_impact_tier` tool compares your calculated avoided CO2 against pre-defined thresholds to categorize the savings as low, medium, or high impact.

This MCP server provides tools to quantify environmental benefits through carbon avoidance. By comparing the energy-intensive primary production process with more efficient recycled production, users can determine the exact kilograms of CO2 prevented from entering the atmosphere. Use get_material_registry to see supported materials, calculate_single_material_savings for individual calculations, and calculate_batch_recycling_impact to assess entire product lists at once.
