Returns ESG/Green-Index tagged Intelligence articles plus carbon scores for L3 packaging indices. Scores are kg CO₂e per unit. CFF-adjusted scores (where pipeline has run) follow EU PEF Circular Footprint Formula (EC 2013/179/EU), cradle-to-gate. Virgin-basis scores sourced from PlasticsEurope LCIA 2023, WRAP 2023, Ecoinvent 3.9, IAI 2023. Scope 3 Category 1 cradle-to-gate material production only. Use for procurement Scope 3 reporting: carbon_score × annual_volume = kg CO₂e.

## Response `200`
