How Manufacturers Can Build a Scalable EPD Portfolio

As the UK construction industry accelerates its transition to low-carbon delivery, manufacturers are under growing pressure to provide transparent, verified product-level data. Environmental Product Declarations (EPDs) have emerged as the recognised mechanism for this, but the industry has now moved beyond single-EPD development.

This article outlines why EPD portfolios matter, the operational barriers manufacturers face, and the frameworks and best practices needed to deliver scalable EPD production.

EPD demand is no longer driven by sustainability teams alone. It has become a cross-business requirement influenced by procurement, sales, technical, and regulatory drivers.

Procurement Demands

Contractors and developers increasingly require verified EPDs as part of tender submissions. Many now request:

• A minimum percentage of products with EPDs
• Verified (not industry-average) values
• EN 15804+A2 compliant data
• WLCA-ready datasets

Manufacturers without EPDs – or with only a handful – are losing visibility in specifications.

Supply Chain Pressure

Designers, QS teams and engineers require EPD data to complete Whole Life Carbon Assessments (WLCA). Their need for accurate, product-specific information drives pressure upstream. Manufacturers now face direct requests for:

• Variant-specific carbon values
• Digital datasets compatible with WLCA software
• Transparency across A1–A3 and A4 modelling

Net Zero Commitments

Many manufacturers have set corporate net zero targets aligned with:

• Science Based Targets (SBT) commitments
• PAS 2080
• Scope 3 GHG emissions reduction pathways

EPDs provide the most accurate and standardised method for understanding, reporting and reducing embodied carbon across a product range.

A scalable EPD portfolio expands beyond single declarations and incorporates structured modelling across product variations.

Multiple Product Lines

Manufacturers often require EPDs across:

• Core product families
• Sub-product groups
• Bespoke products
• New materials introduced into the market

Variant Modelling

Construction products frequently come in hundreds or thousands of variations. A scalable EPD approach uses:

• Parametric LCA models
• Variant rulesets
• Configurable datasets

This enables EPDs to be generated for groups of variants rather than modelled individually.

Verified vs non-verified EPDs

A mature EPD portfolio includes:

• Verified EPDs for high-demand commercial products
• Non-verified carbon datasets (pre-EPD) for early design stage conversations
• Modular LCA results for internal innovation and R&D

The goal is flexibility – providing the right level of detail at the right time in the sales cycle.

Despite rising demand, many manufacturers struggle to produce EPDs efficiently at scale.

Data Inconsistencies

Product lines often use different:

• ERP systems
• Bills of materials
• Data structures
• Production datasets

This makes lifecycle modelling inconsistent and time-consuming.

Disconnected Systems

Carbon data is typically stored across:

• Spreadsheets
• Manufacturing systems
• Supplier datasets
• Energy reports
• QA systems

LCA modellers spend significant time reconciling inconsistent information.

Manual Processes

Many EPDs are still produced via:

• Manual data gathering
• Spreadsheet-based modelling
• One-off verification processes

This is not scalable beyond a small number of EPDs.

Cost Bottlenecks

Manufacturers often face:

• High software licence fees
• Time-intensive verification
• Repetition of modelling work across similar products

Without a portfolio approach, EPD costs grow exponentially.

Leading UK manufacturers are adopting a structured approach that enables repeatable, efficient EPD generation.

Data Governance

Establish a cross-business process for:

• Standardising input data formats
• Centralising manufacturing datasets
• Ensuring version control
• Setting data quality thresholds

Data governance eliminates inconsistencies and accelerates modelling.

Master PCR Strategy

Most manufacturers require multiple PCRs. A scalable portfolio needs:

• A master PCR mapping strategy
• Clear allocation rules
• Harmonised approaches across product groups
• Alignment with the most relevant programme operator requirements

This ensures consistency and comparability across declarations.

Standardised Modelling Rules

Create a technical rulebook covering:

• Cut-off criteria
• Allocation procedures
• Background dataset selections
• Transport assumptions
• Packaging rules
• End-of-life modelling

This ensures every EPD follows consistent methodology.

Verification Cycles

Instead of verifying each EPD in isolation, manufacturers should implement:

• Batch verification
• Template-based reviews
• Pre-verified modelling approaches
• Periodic re-verification aligned with PCR validity

This reduces verification time and cost while ensuring quality.

Leading sectors have begun scaling EPD production using the frameworks above.

Construction Product Manufacturers

Aggregates, concrete, asphalt, timber and glazing producers are adopting parametric LCA systems to model thousands of variants efficiently.

Insulation Manufacturers

Insulation producers are building multi-facility EPD portfolios to reflect varying manufacturing processes while maintaining standardised modelling rules.

Steel & Metal Manufacturers

Steel fabricators and metal producers are embedding EPD generation into:

• Mill-level data systems
• Multi-plant production
• Digital product passports

These industries are at the forefront of EPD scalability.

Cost to Build an EPD Portfolio

Costs typically involve:

• Initial data system upgrades
• Modelling frameworks
• Verification cycles
• Internal process alignment

However, portfolio-level design significantly reduces cost per EPD.

Procurement Uplift

Manufacturers with complete EPD portfolios experience:

• Increased shortlist rates
• Preferential treatment in tender scoring
• Enhanced WLCA compatibility
• Supply chain alignment with carbon-first procurement

Tender Win-Rate Improvements

Firms with strong EPD coverage report:

• Higher win rates on public-sector tenders
• More consistent specification at RIBA Stage 2–4
• Greater resilience against competitor substitution

The commercial return far outweighs the cost of EPD development.
