What is ESG? & Why It Matters

ESG — Environmental, Social, and Governance — is a set of criteria used by investors, procurement teams, regulators, and trading partners to evaluate how a company manages its impact on the world and how transparently it operates. It emerged from the socially responsible investment movement of the 1970s but became mainstream after a landmark 2004 UN report titled "Who Cares Wins" argued that companies integrating ESG factors would outperform over the long term.

Unlike financial metrics, ESG captures non-financial risks and opportunities: the carbon footprint of your operations, how fairly you treat workers in your supply chain, whether your board has adequate oversight of compliance, and whether you can prove all of the above with verified documentation.

For manufacturers, suppliers, and procurement teams, ESG is no longer an abstract concept. It is a procurement prerequisite, a regulatory requirement, and increasingly, a condition for access to capital markets.

The E in ESG covers a company’s relationship with the natural environment. At its core, environmental reporting tracks greenhouse gas emissions across three scopes: Scope 1 (direct emissions from operations), Scope 2 (indirect emissions from purchased energy), and Scope 3 (all other indirect emissions including the entire supply chain).

CSRD’s ESRS E1 standard requires companies to disclose a complete GHG inventory aligned with the GHG Protocol. This means manufacturers must now gather emissions data from their suppliers — not just their own facilities. Beyond carbon, environmental reporting covers energy management (ISO 50001), water consumption and recycling, biodiversity impact, and waste management.

The S in ESG covers a company’s relationships with employees, suppliers, customers, and the communities where it operates. For supply chains, this means documenting labor practices not just in your own operations, but across every tier of your supplier network.

LkSG makes this legally enforceable. It requires companies to conduct regular human rights due diligence, maintain documented processes for identifying risks, and take corrective action when violations are found — in their own operations and in their direct suppliers. From 2024, this extends to indirect suppliers where there is substantiated knowledge of a violation.

Key social documents include a Human Rights Policy Declaration, a Code of Conduct for Suppliers, and evidence of internal grievance mechanisms. Workforce diversity data, wage equality metrics, and safety incident records are increasingly required by procurement frameworks like EcoVadis.

Governance covers how a company is directed and controlled. For supply chain compliance, governance documentation proves that your organization has formal policies, processes, and oversight mechanisms in place — not just good intentions.

Core governance documents include a Code of Business Conduct, an Anti-Corruption and Anti-Bribery Policy (often certified under ISO 37001), a Supplier Code of Conduct, and a Data Privacy Policy. CSRD’s ESRS G1 requires disclosure of business conduct policies, confirmed incidents of corruption, and anti-corruption training.

ESG scoring translates documentation completeness and compliance status into a numerical score. Atlasia uses three document weight tiers: Critical (3×) for documents that directly impact supplier qualification (e.g. IATF 16949, ISO 9001), Important (2×) for documents expected by procurement teams (e.g. EcoVadis, ISO 50001), and Standard (1×) for governance and policy documents.

Draft documents receive 30% of their full weight — rewarding progress without overstating readiness. The resulting score maps to readiness levels: Foundation, Structured, Operational, Integrated for governance, and Initial, Developing, Aligned, Industry-Ready for sector-specific alignment.
