What ESG Data Should Malaysian Suppliers Start Measuring Malaysia
What ESG Data Should Malaysian Suppliers Start Measuring Malaysia
When a customer asks your company for ESG data, it may not be clear what information should be collected first.
Should you measure electricity consumption?
Indoor air quality?
Carbon dioxide?
Water quality?
Noise?
Machine vibration?
The answer depends on your operations and customer requirements.
A Malaysian supplier does not need to purchase every type of environmental instrument immediately. Start with the data that is relevant to your facility, production process and supply-chain customers.
1. Electricity and Energy Consumption
Electricity usage is one of the most practical areas to begin monitoring.
Start by collecting:
Monthly electricity consumption
Operating hours of major machines
Generator fuel usage
Electricity used by different production areas
Energy consumption before and after improvements
Electricity bills provide an overall figure, but they may not explain which machine or department uses the most energy.
Further checking may require:
Clamp meters
Power meters
Power-quality analysers
Thermal imaging cameras
Temperature measuring instruments
The correct equipment depends on whether you need a simple electrical check or detailed energy monitoring.
2. Factory Temperature and Humidity
Temperature and humidity can affect:
Raw materials
Finished products
Electronic components
Packaging
Warehouse conditions
Employee comfort
Production processes
Do not take only one reading near the factory entrance.
Compare several locations, such as:
Production Area → Temperature + RH
Warehouse → Temperature + RH
Loading Bay → Temperature + RH
Air-Conditioned Room → Temperature + RH
Reported Problem Area → Temperature + RH
A handheld temperature and humidity meter is suitable for walk-around inspections.
If conditions change during the day or overnight, a temperature and humidity data logger may be more appropriate.
3. Indoor Air Quality
Indoor air quality may be relevant to factories, offices, laboratories, warehouses and other occupied areas.
Common parameters include:
CO
PM2.5
PM10
TVOC
Temperature
Relative humidity
A multi-parameter air-quality monitor can provide a general indication of changing indoor conditions.
For example:
CO → Ventilation conditions in occupied rooms
PM2.5 → Fine particles, haze or dust
TVOC → Changes associated with volatile compounds
Temperature and RH → Indoor environmental conditions
Portable instruments such as selected Temtop air-quality monitors can be used for spot checks and temporary monitoring.
However, a general air-quality monitor does not identify every individual gas or chemical compound.
4. Gas Detection
Factories handling gases, chemicals, fuel or confined spaces may need dedicated gas detectors.
Possible gases include:
Oxygen O
Carbon monoxide CO
Hydrogen sulphide HS
Combustible gas LEL
Ammonia NH
Sulphur dioxide SO
The instrument must have a sensor designed for the target gas.
Do not assume that a standard four-gas detector can detect every toxic gas, refrigerant, VOC or chemical vapour.
Before selecting a detector, confirm:
What gas may be present?
Where will the detector be used?
Is the application personal protection, leakage checking or confined-space entry?
Is diffusion or pump sampling required?
Portable options may include suitable models from OTYWELL, Wintact and Benetech, depending on the target gas and application.
5. Noise Levels
Noise measurements may support factory maintenance, workplace screening and equipment comparison.
Useful measurement locations include:
Production machines
Compressors
Generators
Pumps
Loading areas
Workshop sections
Areas where workers report excessive noise
Compare readings under similar operating conditions.
For example:
Machine Running Normally → Measure
Machine Under Heavy Load → Measure
Before Maintenance → Measure
After Maintenance → Measure
A handheld sound-level meter is useful for spot checking.
Formal occupational-noise assessment may require a suitable instrument, measurement method and competent assessment process.
6. Machinery Vibration
Machine vibration can provide useful information about changing mechanical conditions.
Applications include:
Motors
Pumps
Fans
Compressors
Blowers
Generators
Rotating machinery
Abnormal vibration may be associated with:
Imbalance
Misalignment
Bearing wear
Mechanical looseness
Foundation problems
Coupling problems
Portable vibration meters such as the Landtek VM6310, VM6360 or VM6380 can support routine machinery checks, depending on the required measurement functions.
The most useful approach is to measure the same machine at consistent locations and operating conditions.
A single reading without previous records may be difficult to interpret.
7. Water Quality
Water-related ESG data may involve:
Incoming water
Process water
Cooling water
Boiler water
Wastewater
Storage tanks
Possible parameters include:
pH
Conductivity
TDS
Dissolved oxygen
ORP
Turbidity
Temperature
The reqired measurement depends on the process and reporting purpose.
A portable water-quality meter can support internal checking, but it does not automatically replace laboratory testing or formal compliance procedures.
Confirm the required parameter before selecting the instrument.
8. Thermal Inspection
Thermal inspection can help maintenance teams identify unusual temperature patterns.
Possible applications include:
Electrical panels
Cable connections
Motors
Bearings
HVAC equipment
Insulation
Production machinery
An infrared thermometer measures a selected spot.
A thermal imaging camera displays a wider temperature pattern.
These instruments are not the same.
For basic surface-temperature checks, an infrared thermometer may be sufficient. For locating abnormal heat patterns across electrical or mechanical equipment, a thermal camera may be more useful.
9. Material Moisture
Material moisture measurement may be relevant after:
Water leakage
Roof leakage
Flooding
Plumbing failure
High-humidity exposure
Building maintenance work
Possible materials include:
Concrete
Screed
Wood
Drywall
Building materials
Meters such as selected Tramex moisture instruments are designed for different materials and applications.
The correct meter should be selected according to the material being inspected.
A moisture reading can support an investigation, but it does not automatically identify the source of moisture.
10. Waste and Material Records
Not all ESG data requires an electronic measuring instrument.
Companies should also record:
Raw-material usage
Packaging consumption
Scrap quantities
Scheduled waste
General waste
Recycled material
Disposal records
These records may already exist in purchasing, production or waste-collection documents.
Measurement equipment should be used where physical operating or environmental data is required.
A Simple ESG Measurement Route
A basic factory inspection could follow this route:
Point 1 Main electrical area
↓
Point 2 Production machines
↓
Point 3 Employee work area
↓
Point 4 Chemical or gas-handling area
↓
Point 5 Warehouse
↓
Point 6 Loading bay
↓
Point 7 Water or wastewater area
↓
Point 8 Reported problem location
Record only the parameters relevant to each location.
Do not use one instrument for measurements it was not designed to perform.
Create a Simple ESG Measurement Record
For routine monitoring, record:
Date
Time
Measurement location
Parameter
Instrument model
Reading
Operating condition
Observation
Corrective action
For example:
LocationParameterReadingObservation
Production AreaTemperature and RHRecord readingNormal operation
OfficeCO and PM2.5Record readingAir-conditioning operating
Motor AreaVibrationRecord readingCompare with previous result
Loading BayTemperature and RHRecord readingDoor frequently open
Water AreapH or conductivityRecord readingIdentify sample source
Using the same measurement locations and recording method makes future comparisons more meaningful.
Spot Checks or Continuous Monitoring?
Portable instruments are suitable for:
Walk-around inspections
Troubleshooting
Comparing several locations
Periodic checking
Initial ESG data collection
Continuous monitoring may be more appropriate when you need:
Overnight records
Daily trends
Automatic data logging
Alarm notifications
Remote access
Long-term monitoring
A handheld reading shows conditions at the time of measurement.
It cannot show what happened several hours earlier when nobody was checking.
Which ESG Measurement Should You Start First?
Start with the areas that are:
Requested by customers
Relevant to your operations
Associated with higher energy use
Connected to worker safety
Causing repeated maintenance problems
Already supported by existing company records
For many Malaysian SMEs, a practical starting group may include:
Electricity consumption
Temperature and humidity
Indoor air quality
Gas safety
Noise
Machine vibration
Water quality
It is better to collect a small amount of consistent and useful data than to purchase many instruments without a clear monitoring plan.
