We are often told not to judge something by its cover. The same principle should apply to cleaning products. A bottle may look sustainable on the shelf because it is smaller, recyclable or labelled with words such as natural, biological or biodegradable. Those characteristics can all matter, but none of them, viewed alone, tells us the full environmental impact of achieving a clean result.
Much of that impact occurs beyond the bottle itself. Before a cleaning product reaches site, raw materials have been sourced, processed and transported, the formulation has been manufactured, and packaging has been produced. During use, dilution, dosage, water temperature, rinsing and repeat application can all influence its footprint. Afterwards, the formulation enters the wastewater system, and the packaging moves into recycling or waste streams.
Judging a cleaning product by just the bottle risks placing too much weight on what is easiest to see. Life cycle assessment provides a more complete view by examining the connected impacts that sit behind the product, its use and its end of life.
You cannot understand a cleaning product’s environmental impact by judging the bottle alone.
A life cycle assessment, usually shortened to LCA, is a structured method for measuring the environmental impacts associated with a product, service or process across defined stages of its life. In simple terms, it looks beyond what a product is made from and asks what was required to make it, move it, use it and manage it at the end of its life.
An LCA will commonly examine raw material extraction, manufacturing, packaging, distribution, product use and end of life. Depending on the goal of the study, its boundary may stop at the factory gate or continue through the use and disposal stages. That distinction matters: a cradle-to-gate figure does not describe the same system as a cradle-to-grave assessment.
The recognised framework is set out through ISO 14040 and ISO 14044, which cover goal and scope definition, inventory analysis, impact assessment and interpretation. For product carbon footprints specifically, ISO 14067 provides requirements and guidance for quantifying greenhouse gas emissions.
The result is not simply a badge or a single sustainability claim. It is evidence that can help identify environmental hotspots, test assumptions and support more informed decisions.
Cleaning is easy to overlook in an organisation’s environmental strategy. Products are often relatively small, distributed across cupboards and sites, and purchased as part of a much wider facilities or operational budget. Their impact is therefore fragmented across products, locations, suppliers and everyday tasks.
Yet commercial cleaning is highly repetitive. One dose may appear insignificant, but that dose can be repeated across hundreds of rooms, thousands of cleaning tasks and an entire national estate. Small differences in formulation, concentration, transport, water temperature or application can become material when multiplied at scale.
Life cycle thinking brings those connected decisions into view. For cleaning products, this can include:
In commercial cleaning, small impacts are multiplied by every dose, every task and every site.
A bottle and its label can provide useful information about the product in front of us: its ingredients, concentration, hazard classification, dosage instructions, certifications and packaging. Packaging matters. So do ingredient choices, biodegradability, concentration and recyclability. The problem begins when one visible characteristic is treated as proof of the product’s total environmental performance.
A smaller container, for example, may use less packaging and improve transport efficiency. Those are meaningful benefits, but they do not automatically describe the impact of the formulation, the manufacturing process, the required dose or the way the product is used. Likewise, terms such as plant-based, natural, biodegradable and reusable may describe valuable characteristics without accounting for the whole lifecycle.
LCAs help move the conversation away from isolated features. They can reveal trade-offs that are otherwise easy to miss: reducing plastic while increasing transport weight, lowering emissions in manufacturing while increasing energy in use, or choosing a reusable system that requires additional collection, washing and redistribution.
This does not make visible sustainability improvements unimportant. It means they should be considered within the wider system rather than used as substitutes for it.
A sustainability claim highlights a feature. An LCA examines the system around it.
| What the bottle shows | What an LCA investigates |
|---|---|
| Ingredients and formulation | How raw materials are sourced and processed |
| Packaging and certifications | Manufacturing, packaging and transport impacts |
| Dilution instructions | The actual dose required |
| Environmental claims | Water and energy used during application |
| Disposal guidance | Wastewater and end-of-life impacts |
Cleaning products are not passive items that are purchased and discarded. They are diluted, applied, agitated, rinsed and repeatedly used by people in live operational environments. This makes the use phase particularly important.
If a product is routinely overdosed, more concentrate is consumed than the intended calculation assumes. If hot water is used unnecessarily, the cleaning process carries an additional energy demand. If a formula requires rinsing, water consumption increases. If inconsistent training leads teams to repeat tasks or use the wrong product, both environmental and operational efficiency can suffer.
The opposite is also true. Concentrated products, accurate dosing, cold-water performance, no-rinse applications, effective training and product rationalisation can reduce several connected impacts. However, those benefits should be supported by suitable evidence and by an operational system capable of delivering them consistently.
This is why products need to be compared on a genuine like-for-like basis. One litre of concentrate is not equivalent to one litre of ready-to-use solution. Their dosage, number of applications, packaging and transport requirements can be significantly different. The fairest comparison therefore considers what each product requires to achieve the same cleaning outcome
LCA figures need context. Before using them to compare cleaning products or support environmental claims, procurement, sustainability and FM teams should understand how the result was produced.
Transparency does not require every dataset to be perfect. Real-world assessments will include limitations and assumptions. What matters is that these are stated clearly enough for the result to be interpreted responsibly.
For many organisations, purchased goods and services sit within Scope 3: the indirect emissions that occur across the value chain rather than from assets directly owned or controlled by the reporting company. Cleaning products may be a relatively small category individually, but they are part of the purchasing decisions that collectively shape a company’s supply-chain footprint.
Product-level carbon information can give sustainability teams more specific evidence than broad spend-based estimates alone. It can help procurement teams examine alternatives on a more consistent basis, while FM and operational teams can identify where product selection, dosing or site adoption may be affecting results.
An LCA should not be treated as a guarantee that one product is universally better than another. Its value lies in showing where impacts occur and creating a more credible basis for improvement. When linked to verified purchasing and usage information, lifecycle data becomes more than a figure in a report: it becomes an operational decision-making tool.
The cleaning industry does not lack environmental claims. What it often lacks is the accessible, consistent data needed to examine those claims within a complete cleaning system
.Organisations need to know more than whether a product is described as green. They need to understand the methodology behind its footprint, the lifecycle stages included, how the product is being purchased and used, and where changes could create a measurable improvement.
That requires collaboration between manufacturers, distributors, procurement teams, sustainability leaders and the people managing cleaning on site. It also requires suppliers to be clear about where direct information has been used, where averages have been necessary and which assumptions sit behind the result.
Better cleaning decisions begin with making the relevant information easier to see and understand. Because when impact remains hidden across products, spreadsheets, suppliers and sites, even organisations with ambitious environmental goals can struggle to act on it.
The cleaning cupboard may occupy only a small part of a building, but the decisions made within it connect to manufacturing, transport, water, energy, waste and supply-chain emissions. The bottle can tell us something about the product. To understand its environmental impact, however, we must also examine the evidence behind it, the way it is used and the wider system in which it operates.
Cleaning has a transparency issue. Let’s talk about it here.
