03

Every decision backed by traceable evidence

Outline shape thin white border on a transparent background.

Most due diligence programmes spend more time collecting data than using it.

beSirius was built to fix this at the structural level.
beSirius structures what your suppliers already disclose, maps it against your criteria, and shows you exactly where the gaps are. Assessment cycles that used to take months take days.

Your own assessment frameworks

Custom assessment frameworks allow teams to design evaluations based on their own criteria, aligned with internal policies, regulatory needs or industry methodologies.

Define evaluation criteria rather than relying on imposed standards

Create different frameworks for each type of counterparty

Support flexible scoring and performance levels

Industry and regulatory frameworks

Run ESG assessments aligned with leading industry and regulatory frameworks, including:
GBA Benchmark, EU Battery Regulation, OECD Due Diligence, ICMM, TSM, IRMA, Copper Mark and more.
‍
The same underlying data and evidence can be reused across multiple frameworks without repeating work.

How it works, step by step.

Step 1. Capture existing evidence

Start with the information that already exists for suppliers, customers or partners.

Audits, certifications and site reports

Policies, procedures and codes of conduct

Sustainability, ESG and due diligence reports

This step focuses on using what is already available, instead of sending broad questionnaires or starting from zero.

Step 2. Create Sustainability Twin™

beSirius automatically builds a Sustainability Twin™ for each counterparty or internal entity.

A structured, living representation of sustainability policies, processes and performance

Evidence organised by topic, site, asset and product group

Continuously updated as new information becomes available

Each Sustainability Twin™ becomes the single, reusable foundation for all assessments that follow.

Step 3. Define the assessment framework

Choose how sustainability performance should be evaluated.

Define your own ESG or sustainability criteria, aligned with internal policies or customer expectations

Or apply regulatory and industry frameworks the system is purpose-built for, including GBA Benchmark, EU Battery Regulation, OECD, IRMA, ICMM, TSM and Copper Mark

Set scoring logic and performance levels relevant to your use case

beSirius is purpose-built to handle complex multi-criteria sustainability frameworks.
