Second-hand machinery and the circular economy: the real impact on your company's carbon footprint

24 March, 2026

When a company evaluates its sustainability strategy, it usually thinks about solar panels, electric fleets, or environmental certifications. But there is a purchasing decision that has an equally relevant impact on the corporate carbon footprint and almost always goes unnoticed: choosing second-hand industrial machinery instead of new.

This is not a green marketing argument. It is a reality backed by data. And if your company has ESG commitments, reports emissions, or simply wants to reduce its environmental impact in a concrete way, this article is for you.

The invisible problem: embedded emissions in new machinery

When we talk about the carbon footprint of an industrial machine, we tend to think only about the emissions it generates during use: the diesel consumed by an excavator, the electrical energy of an articulated platform, the gases from a tower crane on site.

But there is another type of emission that does not appear on the energy bill: embedded or lifecycle emissions, also known as Scope 3 emissions under the GHG Protocol methodology. These are generated during the extraction of raw materials, the manufacturing of the equipment, its transportation, and assembly.

Manufacturing a medium-sized excavator requires between 15 and 25 tonnes of steel, aluminium, copper, and other materials. The associated metallurgical process can generate between 35 and 60 tonnes of CO₂ before the machine has worked a single hour. For heavier machinery, that figure multiplies considerably.

When you buy new machinery, you take on those embedded emissions in full. When you buy used machinery, those emissions were already generated in the past. You do not produce them. You simply extend the useful life of an asset that already exists.

What is the circular economy applied to industrial machinery?

The circular economy is a productive model that seeks to keep resources in use for as long as possible, extracting maximum value from them before they reach the end of their useful life.

Applied to industrial machinery, this principle translates into something very concrete: instead of manufacturing a new piece of equipment to replace one that still works, a second life is given to that equipment — through inspections, repairs, and certifications — and it is put back on the market.

This cycle generates benefits on three levels:

• Environmental: the manufacture of a new piece of equipment and all associated emissions are avoided.
• Economic: the buyer gains access to a quality asset at a significantly lower cost.
• Industrial: productive capital that would otherwise become waste is kept in operation.

CYCLICA operates precisely within this model. Every machine it sells is a piece of equipment that has been assessed, verified, and prepared to continue generating value, rather than being scrapped or abandoned.

The real impact in numbers: how much CO₂ do you avoid by buying used?

Putting concrete figures to the environmental impact of acquiring second-hand machinery helps to understand the true scale of the decision.

Estimates based on life cycle analysis (LCA) for construction and industrial machinery. Actual values vary by manufacturer, model, and configuration.

In other words, acquiring a used excavator instead of a new one can be equivalent to eliminating between 8 and 12 years of emissions from a conventional passenger vehicle. This is a real, measurable, and reportable impact.

Why this matters now: regulation, ESG, and the supply chain

The pressure on companies to reduce their carbon footprint is no longer purely ethical. It is regulatory and commercial.

The European CSRD (Corporate Sustainability Reporting Directive), in force since 2024, requires a growing number of companies to report their Scope 3 emissions — including those associated with acquired capital goods. Large corporations are also passing this requirement down to their suppliers and subcontractors through their approval criteria.

This means that if your company works with large industrial clients, construction firms, or multinational groups, in the coming years you may be asked how much CO₂ you generated when renewing your machinery fleet. Having a clear — and favourable — answer could make a difference in a tender.

Buying verified used machinery is not just a smart financial decision. It is also a strategic decision for your company's future competitiveness.

How to report the environmental impact of your used machinery acquisitions

If your company prepares sustainability reports or wants to quantify the environmental benefit of opting for second-hand equipment, here are the basic steps:

1. Identify the embedded emissions of the equivalent new equipment. You can consult life cycle analysis (LCA) databases such as EcoInvent or data published by manufacturers under the ISO 14040/14044 methodology.
2. Apply the avoidance factor. By acquiring the used equipment, the manufacturing emissions were already attributed in its original lifecycle. Your company does not generate them.
3. Document the transaction. The purchase invoice, the original manufacturing date of the equipment, and its verified technical condition are the documents that support the calculation.
4. Include it in your Scope 3 reporting. Under the GHG Protocol, emissions avoided through the acquisition of second-hand goods can be reported under the category "Acquired capital goods."

Well-purchased used machinery is not a compromise. It is an advantage.

There is still a prejudice that opting for second-hand machinery means accepting technical risks or missing out on the latest technology. The reality of today's market dismantles that argument.

The leading manufacturers — Caterpillar, Komatsu, Liebherr, Sandvik — produce equipment designed to last decades. A machine with 5,000 hours of use against a potential of 20,000 is in full productive life. With proper maintenance, its operational performance is comparable to that of a new piece of equipment, at a fraction of the cost and with a radically lower environmental impact.

At CYCLICA, all equipment goes through a rigorous technical evaluation process before being sold. This means the buyer receives not just a machine, but the information needed to know exactly where it stands in its lifecycle and what performance to expect.

Conclusion: every used machine you buy is a sustainability decision

The transition to more sustainable production models does not always require large investments in new technology. Sometimes, the greenest decision is also the most economically rational one: giving a second life to a piece of equipment that still has a great deal to offer.

Buying used industrial machinery through verified platforms like CYCLICA means actively contributing to the circular economy, reducing your company's Scope 3 emissions, and making smarter purchasing decisions. All at once.
