THE HIDDEN CARBON FOOTPRINT OF CHAIN SLINGS

A LIFECYCLE PERSPECTIVE FOR PROCUREMENT & BUYING TEAMS

Sustainability in industrial procurement has matured rapidly. Carbon reporting, supplier assessments, and Scope 3 emissions are no longer abstract concepts; they are active decision drivers. Yet within this shift, many critical categories of equipment remain largely invisible in environmental discussions.

One of these blind spots is lifting equipment - and in particular, chain slings.

Chain slings are essential to heavy industry. They are specified by engineers, relied on by operators, and quietly approved by procurement as 'standard items'. But beneath their familiar appearance lies a surprisingly complex environmental footprint - one that depends less on the product itself and more on how it is sourced, maintained, and managed over time.

For procurement and buying teams, understanding this lifecycle is becoming increasingly important.

WHY CHAIN SLINGS DESERVE ATTENTION IN CARBON CONVERSATIONS

Chain slings sit at an uncomfortable intersection in sustainability reporting. They are:

Steel-intensive products
Used across carbon-heavy sectors (construction, steel, energy, offshore, manufacturing)
Long-lived and often reused for years

Because of this longevity, chain slings are frequently excluded from sustainability assessments. They are perceived as “minor” purchases compared to vehicles, machinery, or energy use.

This assumption is misleading.

From a lifecycle perspective, most of the carbon associated with a chain sling is embedded before it ever reaches site. For procurement teams tasked with reducing Scope 3 emissions, this makes chain slings a category worth examining—not because they are disposable, but because they are manufactured through highly energy-intensive processes.

STAGE ONE: EMBEDDED CARBON IN ALLOY STEEL PRODUCTION

The environmental footprint of a chain sling begins long before it is assembled.

Lifting-grade chain is produced from high-strength alloy steel, which requires:

Iron ore extraction and processing
Transportation of raw materials
Energy-intensive steelmaking
Alloying with elements such as chromium, molybdenum, and nickel

These alloying elements are essential for achieving the strength, toughness, and fatigue resistance demanded by lifting applications - but they also increase the carbon intensity compared to standard structural steel.

From a procurement standpoint, this matters because:

The largest proportion of emissions occurs upstream
Price pressure alone does not reduce carbon impact
Supplier manufacturing routes (e.g. electric arc furnace vs blast furnace) can significantly influence embedded emission

Once produced, this carbon is “locked in.” The question then becomes how effectively that embodied carbon is utilised over the sling’s working life.

STAGE TWO: MANUFACTURING, HEAT TREATMENT, & QUALITY ASSURANCE

Chain slings are not simply cut steel assembled into shape. They undergo extensive heat treatment and testing to meet Grade 80 or Grade 100 performance standards.

This includes:

Forging of links and fittings
Quenching and tempering processes
Controlled cooling cycles
Proof testing and sample destructive testing

Each stage consumes energy. From a sustainability perspective, this introduces an important tension: the same processes that make chain slings safe and reliable also increase their manufacturing footprint.

For buyers, this highlights a key insight:

Sustainability in lifting equipment cannot be achieved by lowering performance standards - it must be achieved by extending useful life.

STAGE THREE: TRANSPORT & DISTRIBUTION: THE OVERLOOKED EMISSIONS

Once manufactured, chain slings typically move through global supply chains:

Raw materials sourced internationally
Manufacturing concentrated in specific regions
Finished assemblies shipped to distributors
Stock then held or redistributed locally

Transport emissions vary widely depending on sourcing strategies. For procurement teams, working with suppliers who:

Hold local stock
Assemble or configure slings domestically
Reduce emergency shipping

…can make a meaningful difference to overall footprint, even if it is rarely quantified explicitly.

THE USE PHASE: WHERE MOST ASSUMPTIONS BREAKDOWN

A common assumption in procurement is that once a chain sling is purchased, its environmental impact is essentially complete.

In reality, the use phase introduces ongoing, often avoidable emissions:

Travel for inspection and testing
Premature replacement due to misuse
Scrappage of assemblies where only one component is damaged
Emergency sourcing of replacements

This is where procurement decisions intersect directly with engineering and operational behaviour.

If chain slings are treated as consumables, their embedded carbon is amortised over a short life. If they are treated as maintainable assets, that same carbon is spread across many years of safe service.

MAINTENANCE VERSUS REPLACEMENT: TEH CARBON CASE FOR SERVICING

This is the most important sustainability lever available for chain slings - and one that procurement teams can actively influence.

Chain slings are modular by design. Individual components such as:

Hooks
Shortening clutches
Connectors
Isolated chain links

can often be replaced following inspection, rather than scrapping the entire assembly.

From a carbon perspective, the difference is significant:

Manufacturing a new sling repeats the full upstream emissions cycle
Servicing and repairing an existing sling avoids most of that embedded carbon

Extending the service life of a chain sling by even 12–24 months through structured inspection and maintenance can materially reduce its lifetime carbon footprint.

For procurement, this reframes servicing:

Inspection and repair are not just compliance costs - they are sustainability actions.

THE LIGHTWEIGHT PARADOX: ARE ALTERNATIVES ALWAYS GREENER?

It is tempting to assume that lighter lifting equipment automatically carries a lower environmental impact. In some applications, that may be true. However, lifecycle analysis complicates this narrative.

Synthetic and textile slings often:

Have shorter service lives in harsh environments
Require more frequent replacement
Present disposal challenges at end-of-life

In contrast, alloy steel chain slings:

Tolerate heat, abrasion, and impact
Degrade visibly rather than invisibly
Can be repaired and re-certified
Are fully recyclable

From a procurement sustainability lens, replacement frequency matters as much as material weight. A product replaced five times over a decade may carry a higher cumulative footprint than a heavier product maintained once.

END-OF-LIFE: RECYCLING & CIRCULARITY

At the end of their service life, chain slings offer a clear environmental advantage: they are recyclable.

Alloy steel can re-enter electric arc furnace processes, contributing to new steel production with lower marginal emissions than virgin material. This aligns well with circular economy principles increasingly referenced in procurement frameworks.

Synthetic materials, by contrast, often face:

Limited recycling pathways
Downcycling
Disposal as waste

For buying teams under pressure to demonstrate circularity, this distinction is increasingly relevant.

WHAT PROCUREMENT TEAMS CAN DO TODAY

Sustainability does not require radical changes to lifting operations - but it does require intentional procurement decisions.

Practical steps include:

Specifying serviceable, repairable chain sling assemblies
Prioritising suppliers that offer inspection and maintenance support
Treating lifting equipment as managed assets, not consumables
Tracking service life and replacement drivers
Including lifting equipment in Scope 3 discussions where appropriate

These actions also deliver parallel benefits: reduced downtime, improved safety assurance, and lower total cost of ownership.

THE LES PERSPECTIVE: LIFECYCLE THINKING IN PRACTICE

At LES – Lifting Equipment Store, we see chain slings across their entire lifecycle - from initial specification through inspection, servicing, repair, and eventual retirement.

This vantage point reveals a consistent pattern:

Slings that are maintained last longer
Longer service life reduces cost, risk, and waste
Sustainability aligns naturally with good engineering and compliance

For procurement teams, this reinforces an important message: responsible sourcing does not sit in opposition to operational efficiency - it supports it.

CONCLUSION: SUSTAINABILITY IS ABOUT LONGEVITY, NOT NOVELTY

Chain slings are neither inherently sustainable nor unsustainable. Their true environmental impact is shaped by decisions made after purchase as much as before it.

For procurement and buying teams, the opportunity lies not in chasing the newest material or the lowest unit price, but in:

Maximising service life
Reducing unnecessary replacement
Partnering with suppliers who support lifecycle management

In heavy industry, where safety and reliability are non-negotiable, the most sustainable equipment is often the one that lasts longest - safely.
