The root methodology lies primarily in exhaustively researching company sustainability information that is published in the public domain.

Published data from 2017 forwards has been incorporated in the ECoLibri Library.

ECoLibri collates and analyses in depth the information available across 3 key pillars (see example):

• Contributions and Impacts to UNGC SDGs (via comparisons against sector agnostic, sector specific and entity specific SDGs: the SDG-strategy)

• Achievements and Best Practices (via a desktop scan: the implementation)

• Performance data that supports the above (via a Performance Data Report: the measurement)

Where relevant, ECoLibri uses terminology that aligns with the European Corporate Sustainability Reporting Directive (CSRD).

By using an algorithmic approach ECoLibri is able to determine a unique Sustainability Index (ESI) that can be spread (company ratings) all over the Library content, across each sector and each ESI key pillar.

Data analysis and simulation allows informative decision making in developing an improvement strategy for the effectiveness of the Sustainability Report, hence for the support of the stakeholders.
