Annual due diligence assessment of IRBC Agreement members shows continued progress

Compliance with this commitment is assessed annually using the Due Diligence Assessment Framework, developed by parties of the Agreement, as a reference point. The 2026 assessment, conducted from April to July 2026, shows that participating companies are progressing with their due diligence.

Compared with the 2024 baseline assessment, both the wind and solar sectors have improved their scores. The wind sector, already relatively mature, rose from 67% to 74%. The solar sector made significant progress, from 36% to 65%. Solar companies that took part in both assessments improved by 24 percentage points on average. This shows the gain is not just the result of new members joining.

Due diligence step 6, OECD Due Diligence Guidance for Responsible Business Conduct, remains the most challenging. Yet, both the wind and solar sector have improved considerably here too. Moving forward, parties need to further improve the accessibility and effectiveness of grievance and remedy processes.

The assessment also points to addressing impacts deeper in the value chain. Companies need to strengthen their ability to identify, prevent and address impacts beyond their immediate business relationships. The Agreement will address defined priorities through collective guidance, knowledge-sharing and impact projects on key materials such as copper (currently ongoing in Peru) and lithium.

Overall the assessment shows the progression of Agreement companies over recent years. The recent results will inform the Agreement's collective due diligence support programme for the coming period.
