# carbon_footprint_calculator

Calculate a company's greenhouse-gas footprint under the GHG Protocol (Scope 1 + 2 + 3, in tCO2eq, tier-2 accuracy ±20%). Returns the emissions breakdown, hotspot identification, 5-8 reduction levers each with capex and payback, an SBTi-aligned reduction trajectory over 5-25 years, the 15 Scope-3 categories in detail, and CSRD/ESRS reporting readiness. When to use this tool: the user needs a carbon assessment for CSRD compliance pre-audit, green-finance access, or supplier ESG scorecards. Inputs: the company profile and its activity data. Delivered by Émilie, the AI Sustainability lead of the Gapup portfolio.

## Why carbon_footprint_calculator is rated Low

This tool performs calculations and analysis based on input data, returning reports and assessments. It reads/computes information (emissions breakdown, reduction levers, reporting readiness) without creating, modifying, deleting, or moving financial assets. The output is informational/analytical, making this a Read-category tool.

From the tool's own definition: "Calculate a company's greenhouse-gas footprint... Returns the emissions breakdown, hotspot identification, 5-8 reduction levers... SBTi-aligned reduction trajectory... CSRD/ESRS reporting readiness"

Risk signals: High parameter count (32 properties)
