Carbon/CO2 Trade Calculator

completedcode_genP2

Description

Build rosetta_core/carbon_calc.py — CO2 emissions calculator for trade corridors using Freightos CO2 API (LIVE, confirmed in freightos_api_live patch). API: POST https://api.freightos.com/api/v1/co2calc, auth: x-apikey header. Modes: FCL, LCL, LTL, air, rail, barge, express. Returns: CO2 emissions (gross/energy weight), sailing/flying distance, EN 16258 report. Integrate with CBAM module for EU carbon pricing. Build: calculate_transport_co2(origin, dest, mode, weight_kg) → CO2Result with emissions_kg, distance_km, mode_factor. Cache results per corridor. Air emits ~50x more than ocean per unit. Tests with mock API responses. Credential: API key in env var FREIGHTOS_API_KEY.
