The TDi CAHRA Index is designed to support supply chain due diligence, and in particular ‘red flag assessment’ as described in the OECD Due Diligence Guidance for Repsonible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.

TDIs unique CAHRA scoring uses both a geometric and arithmetic mean alongside a qualitative phase 2 assessment from our expert analysts. This ensures our scoring is highly accurate and tried and trusted by hundreds of companies.

We combine ten indices published by international institutions and civil society bodies to produce the TDi CAHRA Index. The eleven indices measure the prevalence of conflict, corruption and governance weaknesses, and shortcomings in human rights and labour rights.
