Cost allocation and incentive mechanisms for environmental, climate protection and resource conservation along global supply chains

Analysis of the cotton, tin, natural rubber, coffee and iron ore supply chains

This report analyses the functioning, power structures and institutional framework of five global supply chains with high environmental and human rights risks: cotton for ready-made garments, tin for solder products, natural rubber for car tyres, coffee for consumption and iron ore for quality steel in the automotive industry. The report finds significant power imbalances in most of the supply cha...read more

Sustainability criteria for carbon dioxide removals

Requirements for sustainability criteria in the EU CRCF proposal and elements to be included in a delegated act

In November 2022, the European Commission put forward a proposal for a regulation for a Carbon Removal Certification Framework (CRCF). The principles laid out in the CRCF proposal of the European Commission and the proposed amendments by Council and European Parliament set minimum sustainability criteria. They are vague and require specification into executable criteria for certification. This rep...read more
