The three letters: E, S and G
ESG stands for Environmental, Social, Governance. It describes a set of non-financial factors that can affect both a company's long-term performance and the effects the company has on people and the environment. ESG is not a single rule or a specific standard, but an analytical lens used by companies, investors, banks and public authorities.
| Pillar | What it covers | Example topics and indicators |
|---|---|---|
| E – Environmental | Impact on the climate and natural resources | Greenhouse gas emissions, energy and water use, waste, pollution, biodiversity |
| S – Social | Relationships with employees, customers, suppliers and the community | Occupational health and safety, fair pay, professional training, customer data protection, human rights in the supply chain |
| G – Governance | How the company is managed, controlled and overseen | Board independence, executive pay, shareholder rights, anti-corruption policies, audit and internal control, transparency |
Why ESG matters
For a company, ESG topics are often “hidden” financial risks: a drought can cut production, a workplace accident can halt operations, and weak governance can lead to fraud or a loss of trust among partners. Managing them carefully can lower costs, ease access to financing and strengthen the company's reputation.
For an investor, ESG information complements traditional financial analysis. It helps identify risks that do not yet appear on the balance sheet, as well as companies that are better prepared for changes in regulation, technology or consumer preferences.
- Access to capital: more and more international lenders and institutional investors ask for ESG data before granting loans or buying securities.
- Supply chains: large customers, including those in the European Union, may ask suppliers for information on emissions or working conditions.
- Risk management: extreme weather events, energy prices and regulatory changes directly affect costs.
- Reputation and talent: employees and consumers pay increasing attention to how responsibly companies behave.
Double materiality, explained simply
A topic is material if it is important enough to be managed and reported. In sustainability, importance can be viewed from two directions, hence the term double materiality.
| Perspective | Key question | Main users |
|---|---|---|
| Financial materiality | How does this topic affect the company's revenue, costs, assets or access to financing? | Investors and creditors |
| Impact materiality | How does the company affect people, the community and the environment? | Society, employees, communities, authorities, and investors too |
Useful clarifications
- ESG is not philanthropy: sponsorships are welcome, but what really matters is how the company runs its core business.
- Material topics differ from one sector to another: for a bank, governance and data protection may weigh more than water use.
- A good ESG score does not guarantee higher returns, and a poor score does not automatically mean a bad investment.
- The pillars are interconnected: strong governance makes environmental and social commitments more credible.
Key takeaways
- ESG stands for environmental (E), social (S) and governance (G), and it is an analytical lens, not a single standard.
- ESG topics can represent real financial risks and opportunities for companies.
- Double materiality combines the topic's impact on the company with the company's impact on people and the environment.
- Material topics depend on the sector, and governance gives credibility to the other two pillars.

Explanation: The structure and independence of the board relate to how the company is run and controlled, which is the governance pillar.
Explanation: Impact materiality looks “inside-out”: how the company affects people, the community and the environment.
Explanation: It is enough for the topic to be material from one perspective; if it is material from both, there is all the more reason to manage and report it.
