Sustainability · 4 min read
Sustainability work becomes manageable when it starts with a defined operating boundary, reliable records, and a small number of accountable actions. For an SME, the first useful question is often where energy, materials, or products are being wasted. Establishing that baseline supports both operational improvements and more precise communication.
Define what you are measuring
Choose the reporting period, locations, and activities before collecting figures. Record electricity in kWh, fuel in appropriate physical units, materials in consistent quantities, and waste by type where records allow. Keep invoices, meter readings, and contractor reports alongside the figures. Identify estimates and missing information so the baseline can improve over time.
Assign an owner for each dataset and agree a monthly collection routine. A shared workbook may be sufficient initially if it has clear definitions, controlled inputs, and a record of corrections. Software can help later, but it cannot resolve an unclear reporting boundary or inconsistent source records.
Distinguish consumption from emissions
Energy use and greenhouse-gas emissions are related measures, but they are not interchangeable. An emissions estimate generally combines activity data with appropriate emission factors and a defined accounting method. Record the factor’s source, year, units, and application so another person can reproduce the calculation.
The GHG Protocol distinguishes direct emissions from owned or controlled operations (Scope 1), emissions associated with purchased electricity, steam, heating, or cooling (Scope 2), and other upstream and downstream value-chain emissions (Scope 3). Its Corporate Standard and Scope 3 Standard provide frameworks for organising an inventory. A first operational energy review should not be described as a complete carbon footprint.
Track absolute results and intensity together
An intensity measure relates resource use to an activity such as units produced. It helps explain efficiency, but should be shown beside total use. Otherwise a business can appear to improve while its overall consumption rises.
Worked example — illustrative figures: A workshop uses 10,000 kWh to produce 2,000 units in a baseline month, or 5 kWh per unit. A comparable later month uses 9,500 kWh for 2,000 units: 4.75 kWh per unit. Both absolute electricity use and electricity intensity have fallen by 5%.
If output instead rises to 2,500 units at 4.75 kWh per unit, total use becomes 11,875 kWh. Intensity remains 5% below the baseline, while total electricity use is 18.75% higher. Reporting both results gives managers a clearer picture. Check product mix, weather, operating hours, and measurement coverage before attributing a change to one intervention.
Choose improvements with a clear owner
Create a short opportunity list with evidence, expected effort, cost, operational dependencies, and an owner. Possible investigations include equipment running during idle periods, avoidable material offcuts, or damaged stock. Validate the opportunity with the people doing the work before estimating savings or committing to a target.
Pilot one intervention where practical. Record when it started and what else changed, then compare equivalent periods. Review quality and service alongside resource use so an apparent saving does not come from producing more rejects or delaying orders. Document results even when the intervention does not perform as expected.
Make claims that the evidence supports
Describe the exact measure, period, and coverage: for example, electricity used at one workshop during comparable months. State material exclusions and estimates. Avoid turning a narrow operational result into a claim about the environmental performance of the whole business.
A practical first cycle is to define the boundary, collect a baseline, select one measurable improvement, and review it after an agreed period. Repeating that cycle builds a record that can support better decisions and more detailed reporting as the business’s needs develop.
