What is ESG? Meaning and relevance for SMEs explained simply

ESG stands for Environmental, Social, and Governance – an evaluation framework for the environmental, social, and corporate governance aspects of a company. ESG is now appearing in customer questionnaires, tender documents, and bank discussions – often without a detailed explanation of what is actually meant by it. Anyone trying to classify the term for the first time usually finds either very superficial definitions or immediately highly complex regulations. This article lies in between: understandable, but concrete enough for practical application.

ESG: the three letters in plain English

E – Environmental: Energy consumption, CO₂ emissions, resource use, waste. For most businesses, this is the most tangible part because it translates directly into costs.

S – Social: Working conditions, employee health, fair pay, diversity – both within one's own business and increasingly across the supply chain.

G – Governance: Transparent decision-making processes, compliance, dealing with conflicts of interest, anti-corruption measures.

The crucial point: ESG is not a single law and not a single certificate, but an evaluation framework. Anyone looking for "the ESG obligation" usually finds nothing concrete – because depending on the context (customer inquiry, bank, tender), there are different, sometimes informal expectations that converge under this collective term.

Why ESG becomes relevant even without a legal obligation

The classic EU reporting requirements (CSRD) primarily affect large companies following the Omnibus reform. For most medium-sized companies, the actual pressure does not arise directly from the law, but indirectly: large customers, who are themselves subject to reporting requirements, pass their data requests down to suppliers (more on this: Sustainability in the supply chain: Why your customers are demanding data now). Banks increasingly ask for ESG indicators when granting loans. Tenders contain ESG criteria as an evaluation factor.

This means: the relevant question is rarely "Am I legally obliged?", but rather "How often am I asked about this in practice – and am I prepared?"

Where the pragmatic starting point lies

The most common mistake when starting with ESG is to begin with the largest building block – such as a full sustainability report according to a formal standard. The reverse order is usually more practical:

1. Record energy data. The "E" part can be linked most directly to cost savings while simultaneously providing the data foundation for everything else.

2. Derive the CO₂ footprint from the energy data (see Creating a CO₂ footprint without consultants).

3. Document governance basics – often already in place but not written down (e.g., responsibilities, basic compliance processes).

4. Only after that, if necessary, tackle a structured report or certification.

The misconception: ESG as a pure compliance issue

Anyone who views ESG solely as a regulatory compliance exercise misses out on the actual benefit: the data foundation for ESG answers – especially in the energy sector – is usually identical to the data foundation for cost savings. Anyone who sets up energy tracking first for cost reasons has already completed most of the ESG preparatory work on the side.

How strait simplifies the entry into ESG

strait starts with energy data collection – continuously via IoT sensors instead of reconstructed once a year from invoices. This first visibly reduces energy costs, and the same auditable data can then be used for the CO₂ footprint, customer questionnaires, or a voluntary report – without having to set up data collection from scratch for every purpose.
