When a procurement asks for “CAM-compliant” materials, it is not asking for certification: it is asking for proof. EPD is the strongest evidence there is, and it is the only one that works outside Italy as well.
In many public tender specifications you will read the phrase “the product must comply with Building CAM.” Often the supplier replicates with a signed sheet where he or she declares compliance, sometimes accompanied by a stamp bearing words such as “CAM Certificate.” Well: neither of these two documents alone is legally sufficient in the new specifications based on Legislative Decree 36/2023 and Building CAM 2022 and 2026.
The reason is that CAM and EPD are not the same thing, nor are they equivalent. They are entities of a different nature: one is a set of requirements that public procurements must meet, the other is a third-party certified document that verifiably proves some of those requirements. Confusing them is a frequent but costly mistake: at the design verification or testing stage, a supplier who cannot provide the right proof stops the construction site.
This article explains the difference in operational terms, why it matters to those installing or designing ACR systems, and why having a product with EPD today is a strategic advantage-not just an ethical one.
Minimum Environmental Criteria (CAM) are environmental requirements that public administrations must include in calls for tenders for works, service and supply contracts. They are not a certification, and there is no body that issues a “CAM mark.” These are regulatory requirements.
The legal framework is as follows:
CAM is organized into three families:
For each criterion, the CAM defines what evidence is allowed to demonstrate compliance. And that is where EPD comes in.
The Environmental Product Declaration**(EPD)**, or Environmental Product Declaration, is a documentary statement that reports the environmental impacts of a product throughout its life cycle, from raw material to end of life. It is regulated by two international technical standards:
The EPD is based on a Life Cycle Assessment (LCA) study conducted according to ISO 14040/14044, which quantifies:
The data are organized by life cycle modules according to EN 15804: A1-A3 (production), A4-A5 (transport and installation), B1-B7 (use), C1-C4 (end of life), D (benefits beyond the system, e.g. material recovery).
Three points worth mentioning:
The difference can be summarized as follows:
| Appearance | CAM | EPD |
|---|---|---|
| Nature | Regulatory requirement for public procurement | Voluntary technical declaration |
| What does it establish | What the product must satisfy | What the product contains and how much it impacts |
| Who issues it | The Ministry (decree) | A manufacturer, validated by third party |
| Is it a certification? | No | Yes, Type III (ISO 14025) |
| Validity | Permanent until further decree | 5 years renewable |
| Scope | Italy (public procurement) | International |
The CAM says, “the product must have at least X% recycled matter, documented durability, low emissions in use.” The EPD says, “This product contains Y% copper from recycling, has a GWP A1-A3 of Z kg CO₂eq per kg, and an expected useful life of W years.” The first is the demand, the second is the proof.
More specifically, EPD is one of the means of evidence allowed by CAM to demonstrate compliance with certain criteria. Building CAM 2022 (under 1.3.4 on means of proof) and CAM 2026 list among the accepted documents:
Simple self-declarations by the manufacturer unsupported by technical documentation certified by an accredited body are no longer allowed-this has changed in recent years.
Building CAM is not a static regulation. Recent evolution has three directions, all of which are relevant to those who supply or install plant components:
Enhanced traceability. CAM 2026 permanently eliminates the loopholes of self-declarations. Demonstrating the recycled matter content in a material or component requires a certified means of proof, and the Type III EPD is the most technically comprehensive because it documents not only the percentage of recycled material but the entire environmental profile.
Extension of LCA from product to building. Both CAM 2022 and CAM 2026 introduce rewarding criteria for projects that apply LCA at the building scale (UNI EN 15978). To conduct that analysis, the designer needs the EPDs of individual materials. A supplier who does not provide them subtracts points from the project.
Alignment with Europe. The new European Construction Products Regulation (CPR 2024/3110) will integrate EPD requirements into the Performance Declarations (DoPs) of CE-marked products in the coming years. EN ISO 22057:2022 also defines the data format for integrating EPDs into BIM models, as required by CAM 2026 for procurements falling under Art. 43 of Legislative Decree 36/2023.
In summary: The direction is clear. EPD is moving from a voluntary tool to a de facto required document, even where it is not yet formally mandatory.
For an installation company or design firm, working with EPD-equipped products is not an ethical detail-it is an operational lever that translates into measurable benefits. Let’s look at them one by one.
In post-D.Lgs. 36/2023 public tenders, the absence of valid means of proof may cause the bid to be excluded or its acceptance to be blocked. A company that routinely uses components with EPDs already has documentation ready, can respond to specifications without asking anything of the supplier, and goes through the verification phase without surprises. For a small or medium-sized company that does not have a structured race office, this is a significant operational savings.
The CAM 2022 and 2026 reward criteria award additional points to:
All these criteria are powered by product EPDs. A contractor proposing components with EPDs allows the designer to accumulate reward points that can be decisive in the award.
The premium building and office segment is increasingly working with voluntary protocols such as LEED, BREEAM, ITACA, GBC Italia, DGNB. All of these schemes award specific credits for the use of materials with EPDs (e.g., LEED v4 – credit “Building Product Disclosure and Optimization – Environmental Product Declarations”). EPD-related credits can be worth up to 5-6 points out of 110 in the final tally of a LEED project. In a market where sustainability certification affects the real estate value and occupancy rate of an office building, these are points that matter.
NRP-funded interventions and new NZEB (Nearly Zero Energy Buildings, mandatory for public administration from 2019 and private from 2021) are by definition subject to CAM and, in many measures, explicitly reward the availability of EPDs. The same applies to regional funds and calls on energy efficiency, where the presence of EPDs in installed materials is often an eligibility requirement or evaluation criterion.
EPDs are mutually recognized among national programs (EPDItaly, EPD International, IBU, French INIES, and so on) through ECO Platform agreements. This means that an Italian installer designing or building works abroad, or working with international clients in Italy, speaks the same technical-environmental language everywhere. For example, the French FDES (Fiche Déclaration Environnementale et Sanitaire) is mandatory for building products sold in France and is based on the same EN 15804 system.
In a quote to a sustainability-conscious private customer, being able to state “the pipes we install have certified EPDs, contain X% recycled copper, have a GWP of Y kg CO₂eq per linear meter” is something that differentiates one bid from another. It is a tangible argument, not greenwashing.
In the ACR industry, until a few years ago, EPD discourse was not mainstream because copper as a material itself had a good profile (100% recyclable without loss of properties, durability of decades) and the focus was on the thermal performance of the system. In recent years, with the growth in the weight of environmental criteria in tenders and the arrival of low-GWP refrigerants, the scenario has changed:
In this context, SCT has developed SMISOL Clim Aeterna®, a pre-insulated system that brings all these elements into a single product: EPD according to EN 15804, compliance with Building CAMs, compatibility with R290, water vapor diffusion resistance factor μ > 45,000 (three times higher than the market standard for pre-insulated pipes), co-extruded sheathing adhered to copper during production (a topic we covered in a previous article on insulation adherence and energy efficiency).
For an installer or designer, choosing Aeterna in a public contract means having the documentation that the client will require ready to go, without having to chase after it.
For those who want to start working with EPD products in a structured way, here is a checklist to use when selecting suppliers:
Documents to be requested:
Data to be extracted from EPD for specifications:
Consistency checks:
CAM establishes what a material or product must warrant in order to be used in a public procurement. The EPD is the most comprehensive and technically rigorous document to demonstrate those assurances. They are not the same thing: without CAM, EPD would be a purely marketing tool; without EPD (or equivalent), many CAMs would remain unverifiable requests on paper.
For a designer, working with EPD-equipped products means having documentary raw material to meet mandatory technical specifications, accumulating points on award criteria, feeding LCA at the building scale, collecting LEED/BREEAM/ITACA credits, and having no problems during verification. For an installation company, it means confidently participating in public tenders and presenting itself to the premium private sector with a solid business case.
The operational message is simple: over the next five years, the presence or absence of EPDs will make the difference between suppliers staying in the public market and suppliers leaving it. Starting now to favor products with certified EPD-even where it does not yet seem essential-means gearing up for a rapidly changing regulatory scenario, rather than chasing after it.
