ESG

Environmental, social and governance (ESG) groups the evidence a company provides about its environmental effects, treatment of people and business oversight when investors, customers or rating providers ask.

What is ESG?

ESG stands for environmental, social and governance. It groups the evidence investors, customers and rating providers ask for about environmental effects, people and company oversight. It is not one standard, score or report; the named request tells you what to answer and prove.

What do E, S and G mean in practice?

  • Environmental: your energy use, greenhouse gas (GHG) emissions, water, waste, pollution and effects on nature.
  • Social: working conditions, pay, health and safety, human rights, workforce practices, customer safety and effects on communities.
  • Governance: who is responsible, who approves decisions, how data is checked, business ethics, anti-bribery controls and how staff can report misconduct.

For a mid-sized company, this work usually sits across finance, operations, human resources, procurement and management. A credible answer names the responsible person, reporting period, company or site covered, evidence used and any gap.

Why does ESG matter to your company?

An investor may send a due diligence questionnaire (DDQ), a structured set of questions used before an investment. Invest Europe's guidance tells fund managers to examine company structure and governance, past incidents, environmental policies and progress, and social policies and enforcement.

A customer questionnaire breaks the same subjects into separate answers and document uploads. EcoVadis assesses company evidence across Environment, Labor and Human Rights, Ethics, and Sustainable Procurement themes. Drive Sustainability SAQ 5.0, a supplier sustainability questionnaire, asks separate questions on company management, human rights and working conditions, health and safety, business ethics, environment and supply-chain management. The request may say “ESG”, but your response still needs the facts and documents named in each field.

How should you handle an ESG request?

Start with the wording you received. Make a simple table with one row per question and columns for scope, period, owner, answer, evidence and gap. Separate policies from actions and results. A policy states what your company commits to do, an action shows what it did, and a result records what happened. Answer for the named company or site, use the requested period, and explain missing data plainly.

What mistakes should you avoid?

  • Sending a broad ESG report instead of answering each question and attaching the evidence requested.
  • Answering only environmental questions while ignoring social and governance evidence in a supplier request.
  • Calling a self-written disclosure an ESG rating. A rating requires an assessor and a stated method.
  • Using group policies or figures without confirming that they cover the company, site and period being assessed.

What is the difference between an ESG rating, ESG reporting and an ESG request?

An ESG rating is an assessment that produces a score or scorecard under the assessor's method. EcoVadis, for example, rates evidence across four themes. ESG reporting is a disclosure prepared under a named law, standard, listing rule or contract. An ESG request is the questionnaire, DDQ, portal task or customer email asking for answers and evidence. A request may feed a rating or report, but the three are not interchangeable.

Is ESG reporting mandatory?

Not merely because someone calls the work ESG. A legal duty depends on the named law, listing rule and the entities it covers. A contract or customer programme can still make a response commercially necessary even when no law requires a public report. Read the exact requirement before deciding what to prepare.

How is ESG different from sustainability?

Sustainability describes how a company manages its long-term effects on people, nature and the business. ESG is a way for investors, customers and rating providers to arrange questions about that work. The labels overlap, but neither tells you which evidence a particular request requires.

Example

Hypothetical example. A 180-person automotive parts supplier receives a Drive Sustainability SAQ 5.0 invitation from a customer. The finance lead confirms which site the invitation covers, then assigns each question to the person who owns the evidence.

  • For questions 5, 9 and 10, answer against the human rights, business ethics and environmental policies that actually cover the site.
  • For question 18, answer “Yes” only if the company has set corporate social responsibility (CSR) or sustainability requirements for suppliers, then upload the document that supports that answer.
  • If question 18 is “Yes”, answer question 18c separately by selecting the process or processes used to review whether suppliers fulfil those requirements. If no review process exists, select “None” for question 18c and record the gap, owner and planned date internally. Do not change a truthful “Yes” to question 18.

Upload each document against the question it supports. Do not substitute a generic ESG report for missing answers, and do not claim that a parent-company document covers the site unless it does.
