For many small and medium enterprises, the hardest part of ESG is not deciding whether sustainability matters. It is deciding where to begin.
A business may be asked about carbon emissions by a multinational customer, employee practices by a procurement team and sustainability policies by a bank—all while operating without a dedicated ESG department.
The result is often one of two extremes: companies either postpone ESG because it appears too complicated, or they attempt to measure everything at once and create a reporting process they cannot maintain.
A more practical approach is to establish a reliable baseline first.
SMEs Do Not Need to Measure Everything Immediately
The ASEAN Simplified ESG Disclosure Guide for SMEs in Supply Chains, or ASEDG, provides a useful regional reference for this approach.
Version 2 contains 38 disclosures across 15 topics under the environmental, social and governance pillars. Importantly for smaller companies, the disclosures are divided into Basic, Intermediate and Advanced categories rather than assuming every organisation should immediately reach the same reporting maturity.
The guide is voluntary and specifically recognises that SMEs may need ESG information because customers, investors or financiers request it.
That creates a useful principle:
Start with information that is measurable, relevant to the business and realistic to maintain consistently.
The Five-Part SME ESG Baseline
Instead of beginning with dozens of indicators, an SME can organise its first ESG baseline around five practical areas.
| Area | Examples of Data | Why It Matters |
|---|---|---|
| Energy & Emissions | Electricity, fuel, Scope 1 and Scope 2 emissions | Establishes environmental baseline |
| Resources & Waste | Water, waste generated, waste diverted | Identifies operational resource use |
| People | Employees, training, workforce composition | Builds social-performance visibility |
| Safety | Workplace injuries and fatalities | Tracks a fundamental workforce risk |
| Governance | Policies, directors, corruption incidents, responsibilities | Creates accountability |
These categories do not represent every ESG issue. They provide a manageable starting architecture.
1. Start With Energy Consumption
Electricity bills are one of the simplest environmental datasets available to many businesses.
An SME can begin by collecting monthly electricity consumption across its offices, factories, warehouses, shops or other operating locations.
Where relevant, businesses should also track fuel consumed by company-owned vehicles or equipment.
This information creates two benefits.
First, it provides a baseline against which future efficiency improvements can be measured.
Second, energy and fuel information can form part of greenhouse-gas calculations.
ASEDG’s Basic environmental disclosures include energy consumption as well as Scope 1 and Scope 2 greenhouse-gas emissions.
2. Build a Basic Emissions Baseline
Carbon accounting can appear complicated, but SMEs do not necessarily need to begin with every possible value-chain emission.
At a basic level, businesses should understand two important categories.
Scope 1 emissions arise directly from sources owned or controlled by the company. Examples can include fuel burned in company vehicles or equipment.
Scope 2 emissions relate to emissions associated with purchased electricity, steam, heating or cooling consumed by the organisation.
Other indirect value-chain emissions fall into Scope 3 and can become important as a company’s reporting maturity increases.
For Malaysian SMEs, Capital Markets Malaysia provides an SEDG GHG calculator designed to help companies estimate Scope 1 and Scope 2 emissions using operational information.
The important first step is not obtaining an impressive carbon number. It is creating a repeatable methodology and retaining the underlying source data.
3. Track Waste and Water Where They Are Material
Not every sustainability metric has the same significance for every business.
Water consumption may be highly relevant to a manufacturer or food-processing company but less material to a small professional-services office.
Likewise, packaging waste may be highly relevant to a retailer or manufacturer.
ASEDG encourages companies to determine which topics and disclosures are material to their own operations rather than treating all 38 disclosures as equally important.
Where relevant, basic information can include:
- total water consumed or withdrawn;
- total waste generated;
- waste diverted from disposal;
- waste sent for disposal;
- major materials used in production or packaging.
Again, consistency matters. Measuring waste for one month and extrapolating an annual sustainability claim without a reliable methodology would provide weak evidence.
4. Do Not Treat ESG as Only an Environmental Exercise
Companies sometimes begin ESG by measuring electricity and recycling while overlooking employees entirely.
The social pillar is equally important.
ASEDG’s Basic social disclosures include areas such as employee training, workforce composition, compliance with applicable minimum-wage laws, occupational injuries and fatalities, and certain human-rights indicators.
An SME could initially track:
- total number of employees;
- workforce composition;
- average training hours;
- recordable workplace injuries;
- health and safety incidents;
- employee turnover where useful.
These indicators can often be sourced from existing payroll, HR or safety systems rather than requiring a completely new ESG platform.
5. Establish Governance Before Creating Ambitious Targets
Measurement becomes difficult when nobody owns the data.
A small business may not need a sustainability committee or dedicated ESG department immediately, but it should know who is responsible for each area.
| ESG Data | Possible Internal Owner |
|---|---|
| Electricity and utility data | Finance / Facilities |
| Fuel consumption | Operations / Finance |
| Waste | Operations |
| Employee information | HR |
| Safety incidents | Operations / HSE |
| Policies and governance | Management / Compliance |
ASEDG’s Basic governance indicators also include matters such as directors, key corporate policies, the year of the most recent audited financial report and confirmed corruption incidents where applicable.
Governance therefore does not have to begin with a sophisticated ESG committee. It begins with clear responsibility, policies and reliable information.
Start With Data You Can Reproduce
An ESG metric becomes more useful when the company can explain where it came from.
For each important indicator, retain information such as:
- the reporting period;
- the source document or system;
- the calculation methodology;
- the employee responsible for collecting it;
- any assumptions used;
- changes made to methodology between reporting periods.
This creates a basic audit trail.
Without it, an organisation may discover next year that nobody remembers how a sustainability figure published this year was calculated.
Measure the Baseline Before Announcing the Target
A common sustainability mistake is announcing a reduction target before understanding current performance.
Consider a company saying:
“We aim to reduce electricity consumption by 20%.”
The statement raises several immediate questions.
- Twenty percent compared with which year?
- Does the figure cover every facility?
- Is the measurement based on electricity consumed or electricity cost?
- Has business growth been considered?
- Who calculates the result?
A target becomes much more useful once the baseline and measurement methodology are defined.
Start Now, Add Later
The following progression can help smaller businesses avoid overcomplicating ESG.
| Stage | Priority |
|---|---|
| Stage 1: Baseline | Collect reliable operational ESG data |
| Stage 2: Consistency | Use the same methodology across reporting periods |
| Stage 3: Performance | Identify improvements and reductions |
| Stage 4: Targets | Set evidence-based objectives |
| Stage 5: Advanced Measurement | Add more complex indicators where material |
This proportional approach is consistent with broader sustainability-reporting thinking. IFRS Foundation guidance recognises that reporting approaches can be commensurate with the skills, capabilities and resources available to an organisation.
Why SMEs May Receive More ESG Data Requests
An SME may not itself be required to publish the same sustainability disclosures as a major listed corporation, but it can still be affected indirectly.
The ASEDG specifically identifies SMEs in supply chains that receive ESG information requests from customers, investors and financiers as intended users of the framework.
This matters as larger businesses strengthen sustainability reporting.
For example, Singapore currently requires listed companies to report Scope 1 and Scope 2 greenhouse-gas emissions from financial years beginning in 2025, with additional ISSB-based climate disclosures phased according to company category.
As large companies improve their own reporting systems, suppliers can increasingly become part of their ESG-data collection processes.
An SME with organised records may therefore be able to respond to customer questionnaires much more efficiently than a business trying to reconstruct several years of sustainability information when a request arrives.
ESG Reporting Is Not the Same as ESG Performance
A company can produce an attractive sustainability report without demonstrating substantial improvement.
Conversely, an SME may be reducing energy consumption, improving safety or cutting waste without formally documenting the progress.
The objective should be to connect the two.
Measurement makes performance visible. Reporting communicates that performance.
Neither should replace actual operational improvement.
From ESG Baseline to Measurable Sustainability Achievement
Once several years of consistent ESG information exist, businesses can begin distinguishing normal improvement from exceptional achievements.
For example, an organisation may eventually document a significant and objectively measurable renewable-energy, recycling, waste-reduction or social-impact milestone.
If such an achievement is specific, evidence-based and independently verifiable, the organisation may consider whether it is relevant to forms of sustainability recognition in Asia, including independent recognition through organisations such as Asia Record.
This should come after measurement—not before it.
An Asia Record recognition should document the specific achievement being recognised. It should not be used to convert an ordinary sustainability commitment into a proven result or to support environmental claims beyond the evidence available.
A Simple SME ESG Starting Checklist
- Choose a reporting period. Usually begin with the most recent full financial or calendar year.
- Identify material topics. Do not measure indicators that have little relevance simply because they appear on an ESG list.
- Assign data owners. Decide who is responsible for each metric.
- Collect source documents. Use bills, payroll records, safety systems, procurement information and operational records.
- Create a baseline. Establish current performance before setting targets.
- Document methodology. Record how each number was calculated.
- Review data quality. Check for missing locations, periods or inconsistent units.
- Track consistently. Repeat the same process in the next reporting period.
- Add complexity gradually. Expand to more advanced ESG measurements when useful.
Good ESG Starts With Better Business Data
SMEs do not need to begin ESG with a lengthy sustainability report, a complicated dashboard or dozens of targets.
A more durable starting point is knowing what the company currently consumes, emits, produces, manages and governs—and being able to support those figures with reliable records.
Once that baseline exists, businesses can identify risks, set realistic targets, respond to stakeholder requests and measure whether sustainability initiatives are actually working.
For smaller companies, ESG becomes much more manageable when the first objective is not to report everything.
It is to measure the right things consistently.
