About WECH-RB
We Create Harmony with Responsible Businesses
WECH-RB is an independent document-review-based certification platform for EHS, ESG, business ethics, anti-corruption, responsible procurement, and supplier due diligence.
WECH-RB combines four proven frameworks into a single, accessible certification: RBA-style supplier Code of Conduct topics, EcoVadis-style ESG and sustainable procurement scorecard topics, FCPA-style anti-bribery and anti-corruption controls, and third-party due diligence and supplier risk screening concepts.
Our first-version certification is document-review based — no on-site audit is required. Applicants apply online, complete a structured questionnaire, upload supporting evidence, and receive an AI-assisted preliminary review followed by an admin document review that determines final certification.
We believe responsible companies help create a safer, more ethical, more sustainable, and more harmonious society — and that credible, evidence-based certification helps buyers and partners recognize them.
