What is an Environmental Product Declaration (EPD)?

An Environmental Product Declaration (EPD) is a third-party verified, standardized document that communicates the environmental impacts of a product throughout its life cycle, based on ISO 14025 standards. EPDs provide transparent, comparable data derived from rigorous Life Cycle Assessments (LCA) as outlined by ISO 14040 and ISO 14044.

Environmental Product Declarations (EPD) Guide for 2026

For construction products common in GCC markets, EPDs often follow EN 15804 guidelines that standardize the calculation and reporting modules for environmental impacts of building materials, supporting green building certifications such as LEED and ESTIDAMA.

Key Takeaway: An EPD is a standardized environmental “nutrition label” that reveals the product’s carbon footprint, resource consumption, emissions, and end-of-life impacts with full transparency and third-party verification.

Why are EPDs Important in 2026?

EPDs have become essential in meeting sustainability goals driven by governments, corporations, and building certification systems. In the GCC region, regulatory pressures and market demand increasingly require manufacturers to provide EPDs to demonstrate commitment to environmental stewardship and compliance with international standards.

For example, LEED EPD certification credits reward projects that prioritize products with verified environmental declarations, validating their contribution to carbon reduction and material transparency.

Moreover, EPDs support corporate environmental disclosure, enable low-carbon purchasing decisions, and help supply chains reduce embodied carbon emissions consistent with national and international climate commitments.

Key Standards and Frameworks (ISO 14025, EN 15804, etc.)

The following international standards form the foundation of EPD development and verification:

ISO 14025: Specifies principles and procedures for Type III environmental declarations to ensure transparency and comparability.
ISO 14040/44: Detail Life Cycle Assessment (LCA) principles, including goal and scope definition, inventory analysis, impact assessment, and interpretation.
EN 15804: European standard specifying Product Category Rules (PCR) for Environmental Product Declarations related to construction products.
ISO 21930: Sustainability in buildings and civil engineering works – Environmental declaration of building products.

These standards guarantee that EPDs accurately assess environmental impacts such as Global Warming Potential (carbon footprint), energy use, water consumption, resource depletion, and end-of-life scenarios.

EPD vs HPD vs LCA: Understanding the Differences

Attribute	Environmental Product Declaration (EPD)	Health Product Declaration (HPD)	Life Cycle Assessment (LCA)
Purpose	Third-party verified report communicating a product’s environmental impact throughout its lifecycle.	Transparent disclosure of product ingredients, focusing on health and safety impacts.	Analytical study quantifying environmental impacts; internal or external use.
Scope	Cradle-to-gate/cradle-to-grave environmental impact assessment.	Chemical composition and potential hazards.	Depends on study scope; often cradle-to-gate or cradle-to-grave.
Standards	ISO 14025, EN 15804, ISO 21930.	HPD Open Standard.	ISO 14040, ISO 14044.
Verification	Mandatory third-party independent verification.	Optional third-party review.	Varies; often lacks external verification.
Use Cases	Used in green building certifications (LEED, BREEAM), procurement, and sustainability reporting.	Material health credits in green building certifications (WELL, LEED).	Product design, eco-innovation, regulatory assessments.

The Step-by-Step EPD Certification Process

Manufacturers seeking an EPD certification typically follow this process:

Step	Description
1) Define Scope & Goal	Identify the purpose, product categories, and geographic scope for the EPD, considering applicable PCRs and target certification programs like LEED EPD credits.
2) Select PCR	Choose the correct Product Category Rule based on market and product type, ensuring compatibility with international and local regulations (learn more about PCR selection).
3) Data Collection	Gather detailed input data on raw materials, energy, transport, manufacturing processes, emissions, waste, and end-of-life assumptions.
4) Conduct Life Cycle Assessment	Using ISO-compliant LCA software and databases, compute environmental impacts according to the PCR guidelines.
5) Draft EPD	Summarize LCA results and product information according to ISO 14025 and EN 15804 standards, creating a clear, standardized report.
6) Third-Party Verification	Hire an accredited verifier such as NSF Sustainability Series or UL to ensure data accuracy and compliance.
7) Registration and Publication	Submit the verified EPD to a recognized program operator for listing in an official EPD database accessible by architects, buyers, and stakeholders.
8) Update & Maintenance	Regularly review and update the EPD every 3-5 years or when significant product/process changes occur.

Benefits of EPD Certification for GCC Manufacturers

Identifies Improvement Opportunities	Enables manufacturers to optimize raw material sourcing, energy use, and waste reduction through LCA insights.	R&D and Manufacturing Teams

EPD Implementation Checklist

Establish clear goals and market requirements for your EPD (EPD Guide for GCC Manufacturers)
Select appropriate Product Category Rule (PCR)
Engage a qualified LCA practitioner or consultant experienced in GCC market needs
Collect detailed material, energy, emissions, packaging, and transport data
Document the product system boundary and declared unit clearly
Review LCA results carefully and prepare draft EPD report
Submit report for third-party verification by accredited organizations like NSF or UL
Register EPD with recognized program operators
Develop internal processes for EPD updates and renewals

Do’s and Don’ts for EPD Development

Do: Use the latest, market-accepted PCRs and standards referenced by ISO and EN 15804.
Do: Ensure transparent, accurate, and traceable data collection for all life cycle stages.
Do: Work closely with third-party verifiers and program operators early in the EPD process.
Do: Leverage EPDs for LEED and other GCC regional green building certifications.
Don’t: Rely on generic or outdated data; product-specific and process-specific data is vital.
Don’t: Treat EPDs as marketing only; they are technical documents requiring rigorous verification.
Don’t: Skip maintenance of EPDs; outdated EPDs may lose credibility and certification benefits.

Common Mistakes in EPD Certification

Confusing LCA with EPD: An LCA is a study, but an EPD is a verified declaration ready for public and certification use.
Using incorrect or incompatible PCRs for the product category and market.
Failing to conduct proper third-party verification by accredited bodies.
Underestimating the scope of data requirements, leading to incomplete or inaccurate EPDs.
Ignoring periodic updates; EPDs must reflect current product design and manufacturing processes.

Frequently Asked Questions (FAQs)

Is an EPD mandatory for LEED certification?: Not mandatory for all products, but LEED credits require a minimum number of products with verified EPDs. This makes EPDs critical for suppliers targeting LEED projects (source).
How long is an EPD valid?: Valid for 3-5 years typically, provided there are no major product or process changes. EPDs should be updated accordingly to maintain certification integrity.
Can small manufacturers afford EPD certification?: Yes, by using sector-wide EPDs, grouping products, and leveraging local consultancy providers, costs and processes can be managed effectively.
What is the difference between EPD and HPD?: EPDs report environmental impacts standardized via LCA, while HPDs disclose chemical ingredients and health hazards. Both serve different purposes in building certifications (HPD guide).
Which standards are critical for EPD certification?: ISO 14025, EN 15804, ISO 14040/44, and ISO 21930 are the core standards governing EPD creation and reporting (ISO 14025).
