All the GSES pillars are structured based on the ISO High Level Structure and the Plan, Do, Check, Act philosophy.
On the platform GSES System, two different assessments can be found: one suited for small and medium sized companies (SMEs – companies with max. 100 fte in the Benelux and max 1000 fte in the rest of Europe) and one for corporates.
Both contain the same core metrics, but the Corporate Assessment also assesses if the organization has conducted an analysis of Context (internal and external issues in relation to CSR), Stakeholders, Risk and opportunities and Leadership.
For SMEs, these topics are also important, but they often lack the resources to do analyses on them. Therefore, SME Scan focusses on the Plan, Do, Check, Act part of the High Level Structure.
The GSES CSR pillar is based on the international guideline for Social Responsibility of Organizations: ISO 26000:2011.
In absence of an international ISO standard for Circular Economy, the Circular Economy pillar of GSE Standard is based on the BS 8001:2017 ‘Framework for implementing the principles of the circular economy in organizations – Guide, British Standards Institution (BSI), 2017’.
The CO2 pillar of GSE-Standard is for the most part based on ISO 14064-1:2019 and ISO 50001:2018. The GSES CO2 pillar standard further contains specific requirements for reporting and verification of the organization’s greenhouse gas (GHG) emissions and CO2 offset/compensation.
The Sustainable Procurement (SP) or Socially Responsible Procurement (SRP) pillar from GSE Standard is based is based on the ISO 20400. SP is a theme that plays a prominent role in organizations that develop and implement a sustainable strategy.
The GSE-Standard Health & Safety (HS) pillar is based on the international standard ISO 45001:2018 ‘Occupational health and safety management systems – Requirements with guidance for use’.
The GSE-Standard for Bio-Diversity is based on the UN Guidance Note on Standard 1: Biodiversity Conservation and Sustainable Natural Resource Management. As yet, there are no internationally accepted certifiable standards available for managing biodiversity on the organizational level, comparable to ISO standards.
