Grade, price, delivery. For decades those three questions decided most steel orders. In 2026 a fourth has joined them: what is the carbon footprint of this steel, and can you prove it?
If you export to Europe, that question now has money attached. And the document that answers it most credibly is an Environmental Product Declaration. This guide covers what EPD steel means, how EPD steel certification in India works, where ISO 14064 reporting and CBAM fit in, and what the process looks like inside a mid-sized Indian mill.
What is EPD steel?
EPD steel is steel that comes with an Environmental Product Declaration: a third-party verified report of the product's environmental impact across its life cycle, usually stated per tonne. The headline figure is Global Warming Potential, in kg CO₂-equivalent per tonne, reported alongside energy use, water, waste and other impact categories. Three sets of rules sit behind every declaration:
- ISO 14025 governs the declaration itself.
- ISO 14040 and 14044 set the life cycle assessment (LCA) method used to calculate the numbers.
- EN 15804+A2 applies to construction products sold into Europe.
On top of these, sector-specific Product Category Rules (PCRs) fix the boundaries and assumptions, so one steel EPD can be compared fairly with another.
One thing gets misunderstood constantly. An EPD is a disclosure, and it carries no pass mark. A mill with a high footprint can publish one just as easily as a mill with a low footprint. The buyer reads the numbers and decides.
Types of steel EPD
You'll come across three kinds, and they don't carry equal weight in procurement.
- Industry-average EPDs pool data from many producers, usually through a trade association. They're useful as a benchmark early in design.
- Product-specific EPDs cover one product from one manufacturer. Most buyers and green building schemes ask for these.
- Facility-specific EPDs report a product made at a single plant, which matters when a company runs sites with very different energy sources.
Most steel EPDs are cradle-to-gate. They cover raw material supply, transport to the plant and manufacturing (modules A1 to A3), and stop when the product leaves the factory.
Why EPD steel matters in India in 2026
The EU's Carbon Border Adjustment Mechanism entered its definitive phase in January 2026. EU importers of steel now carry carbon-linked obligations based on the embedded emissions of what they buy. For an Indian exporter, four consequences follow.
- No data means default values
If your importer can't get verified emissions data from you, they may have to fall back on default values. Those are set conservatively and can push their cost up.
- The cost rises every year
CBAM is being phased in as free allowances in the EU's own carbon market are phased out. The burden is modest in 2026 and grows steadily toward full exposure in the mid-2030s. Buyers are picking long-term suppliers today based on where that cost is heading.
- Low-emission suppliers become cheaper suppliers
Two mills quoting the same price per tonne are no longer equal if one carries a much lower carbon cost at the border.
- An EPD supports CBAM reporting but doesn't replace it
CBAM has its own calculation rules. Still, the plant data, energy records and verification discipline behind an EPD make CBAM reporting faster and easier to defend.
India's own framework is catching up
In December 2024 the Ministry of Steel released India's Green Steel Taxonomy. It rates steel by emission intensity per tonne of finished steel, with NISST as the nodal agency for measurement and certification. Steel below 2.2 tCO₂ per tonne qualifies as green. Steel below 1.6 tCO₂ earns the top 5-star rating.
Add the Carbon Credit Trading Scheme, SEBI's BRSR value-chain disclosures, and the embodied-carbon expectations of IGBC, GRIHA and LEED. The direction is hard to miss: verified product-level data is becoming standard in the domestic market too.
EPC contractors are screening suppliers on carbon
Large contractors now have Scope 3 targets of their own, and your steel sits inside them. Suppliers who can't share verified emissions data increasingly get filtered out before price is even discussed.
EPD steel certification in India: how it works
A quick note on wording first. Strictly, an EPD is "verified and published", not "certified". The industry calls the whole process certification anyway, so we'll use the term here. For an Indian steel manufacturer the process typically runs in six stages over three to six months:
- Choose a programme operator recognised in your target markets. Europe-focused exporters often pick the International EPD System.
- Select the right PCR for your product: pipes, hollow sections, strips or structural steel.
- Collect at least 12 months of plant data. That means raw materials, scrap, grid and captive power, fuels, process emissions, water and waste.
- Run the life cycle assessment through a qualified LCA practitioner. The scope is usually cradle-to-gate.
- Get independent third-party verification of both the data and the method.
- Publish the EPD. It is generally valid for five years.
Where Indian mills usually struggle
The LCA software is rarely the hard part. The data is. Energy and material records tend to be scattered across departments and spreadsheets, with no single team owning the numbers. Many mills depend heavily on purchased inputs (hot-rolled coil, billets, sponge iron) whose suppliers share no emissions data at all. And India-specific background datasets in LCA tools are still limited, so the practitioner has to work harder to model local power and materials accurately.
Vertically integrated manufacturers with digital emission tracking move through the process far faster, because most of the footprint sits inside their own gate where they can measure it.
How to read a steel EPD
Say a supplier sends you a 20-page PDF. You don't need to read all of it. Check five things:
- Declared unit. For steel it should be one tonne of product. If it's different, the numbers won't line up with other steel EPDs.
- Modules covered. Look for A1 to A3 at minimum, and note whether later stages are included.
- GWP figure. This is the kg CO₂-equivalent per tonne that feeds your embodied-carbon calculation.
- PCR and programme operator. Two EPDs are comparable only when they follow the same rules for the same product type. Pipe against pipe, never pipe against rebar.
- Registration number and validity date. Confirm both on the programme operator's public registry. An expired EPD is a historical document.
EPD steel and ISO 14064 reporting: different jobs, same foundation
ISO 14064 tells the market how much your company emits. An EPD tells your customer how much their specific purchase emits. People mix the two up because both end in a verified carbon number. They answer different questions for different readers.
| ISO 14064 | EPD | |
|---|---|---|
| Scope | Whole organisation | One product, per tonne |
| Covers | Greenhouse gases (Scope 1, 2 and 3) | Carbon plus water, energy, waste and more |
| Main users | Investors, regulators, ESG ratings | Buyers, architects, importers |
| Verification | ISO 14064-3 | Programme operator rules |
The two strengthen each other. A verified ISO 14064 inventory gives you reliable Scope 1 and 2 plant data, and that data becomes the backbone of the manufacturing stage in an EPD. If you've already been through an ISO 14064-1 verification, a large part of the EPD data collection is done.
ISO 14067, the standard for a product's carbon footprint, often acts as the bridge between them. It takes the organisational data and allocates it to a tonne of product, which is the step an EPD then builds on with the wider set of impact categories.
For export buyers, especially in Europe, having both is fast becoming the expectation. It's a large part of why global buyers are looking for low-carbon steel suppliers they can verify on paper.
EPD steel case study India: an illustrative journey
This is an illustrative composite based on the typical path of a mid-sized Indian manufacturer. It does not describe a specific company.
The company. A mid-sized ERW pipe and tube maker in eastern India, producing around 20,000 tonnes a month, with about 30% of output going to Europe and the Gulf.
The trigger. A long-standing EU distributor asked for verified product-level emissions data ahead of CBAM's definitive phase. It also made clear that volume would shift to suppliers who could provide it.
Months 1 to 2: getting the data house in order
The first surprise was how fragmented the numbers were. Power bills sat with finance, fuel logs with production, raw material records with procurement. Nobody had ever put them on one page.
The team installed sub-meters on key process lines and moved records into a single digital system. In parallel they started an ISO 14064-1 inventory to establish verified plant-level emissions.
Months 3 to 4: life cycle assessment
With clean data in hand, the company appointed an LCA consultant, selected a programme operator recognised in Europe, and chose the PCR for steel construction products.
Then came the finding that reshaped the project. Purchased hot-rolled coil made up the largest share of the footprint, well ahead of anything happening inside the tube mill. So the team went back to its coil suppliers and asked for their emissions data.
Months 5 to 6: verification and publication
The third-party verifier flagged gaps in transport data. Those were corrected, the EPD was published, and it went to the EU distributor.
What changed afterwards
- The distributor kept and expanded its volume, using the verified figures in place of default values.
- The company qualified for two domestic green building projects that required EPDs.
- The data showed where the biggest reductions were possible, starting with lower-emission coil and rooftop solar
The lesson is that the EPD itself was the last step. The real work, and most of the business value, came from organising data the company had never measured properly before.
How Renny Strips is building its EPD foundations
Several Indian manufacturers already have the building blocks of an EPD in place. Ludhiana-based Renny Strips Limited is one of them.
Its facilities are vertically integrated and track emissions from raw materials through to finished goods. HR coils, tubes and wire rods are produced in-house, which cuts logistics emissions and closes the supplier data gap that slows most Indian mills. A 22 MW captive solar plant meets nearly 30% of the company's energy needs, and Renny holds a 5-Star Green Steel Rating from the Ministry of Steel (our guide to green steel in India explains how the ratings work).
The company reports carbon emissions up to 40% lower than the industry average, with practices aligned to CBAM, and has stated an ambition to take that reduction to 50%. It also offers a downloadable emission report on its sustainability page.
With verified plant-level data, renewable power and integrated production already there, the path to a published, third-party verified EPD is much shorter.
Six questions to ask your steel supplier
Before your next order, ask:
- Do you have a verified EPD, or a dated roadmap to one?
- What is your verified emission intensity per tonne?
- What is your rating under India's Green Steel Taxonomy?
- Is your organisational GHG inventory reported under ISO 14064?
- Can you provide installation-level emissions data for CBAM?
- Is your data tracked digitally and available for audit?
A supplier who has done the work will answer all six in one email. Vague answers mean the risk sits with you.
Transparency is the new quality standard
ISO 9001 once separated serious manufacturers from the rest. Verified environmental data is doing the same job today. Indian steel makers who build that data foundation now will be the preferred partners for Europe-bound exports and for India's next wave of green infrastructure. If you're a buyer, start with the six questions above. If you're a manufacturer, start with your meters.
Frequently asked questions
What is EPD steel?
EPD steel is steel with an Environmental Product Declaration, a third-party verified report of its life cycle environmental impacts based on ISO 14025 and, for construction products, EN 15804.
Is EPD certification mandatory in India?
Not currently. But export buyers, EPC contractors and green building projects increasingly expect it, so in practice it's becoming a condition of doing business in those segments.
What is the difference between an EPD and ISO 14064?
ISO 14064 measures a company's total greenhouse gas emissions. An EPD reports the environmental impact of one specific product, per tonne.
Does an EPD help with CBAM?
It doesn't replace CBAM's own methodology. The verified data behind an EPD does make CBAM reporting faster and more credible.
How long is a steel EPD valid?
Generally five years, after which it must be updated with fresh production data.
