EPD - Everything You Need To Know

Environmental Product Declarations (EPDs) have become an essential tool for companies committed to transparency in their environmental impacts. By providing a standardized, third-party verified statement of a product’s life cycle environmental performance, EPDs enable companies to communicate credible and comparable data to investors, regulators, customers, and other stakeholders. This guide is aimed at sustainability professionals looking to refine their EPD processes, benchmark their performance against industry leaders, and integrate EPD insights into broader sustainability strategies.

An Environmental Product Declaration (EPD) is a standardized document that provides quantifiable information about the life cycle environmental impacts of a product or system. Based on a rigorous Life Cycle Assessment (LCA), an EPD typically includes data on:

• Global Warming Potential (GWP): Greenhouse gas emissions across the product life cycle (Scopes 1, 2, and 3).

• Resource Use: Energy, water, and raw material consumption.

• Waste and Emissions: Quantitative insights into waste generation and pollutant discharge.

EPDs are developed following recognized international standards (such as ISO 14025 and the relevant European standards like EN 15804) and require third-party verification to ensure credibility. For companies that already utilize EPDs, deepening expertise in EPD design is critical to enhancing product transparency and driving market differentiation.

For a robust and comparable EPD, familiarity with the following standards and guidelines is essential:

• ISO 14025: Defines the principles and procedures for Type III environmental declarations, ensuring that information is validated, comparable, and transparent.

• EN 15804: Provides core rules for environmental product declarations in the building sector, frequently used for construction products.

• Product Category Rules (PCRs): These are sector- or product-specific guidelines that detail how to conduct an LCA and report an EPD. PCRs ensure that EPDs within a particular category maintain consistency, thereby allowing for effective benchmarking.

• Life Cycle Assessment (LCA): The foundation of EPDs, LCA involves compiling and analyzing the environmental impacts of a product from cradle-to-grave. It is critical that companies use robust and verified LCA methodologies to support their EPD claims.

• Cradle-to-Gate Approach: The cradle-to-gate approach is a specific methodology within LCA that evaluates the environmental impacts of a product from the extraction of raw materials ("cradle") up to the point it leaves the manufacturing facility ("gate"). This approach focuses on the initial stages of the product life cycle, providing insights into the environmental footprint associated with production processes. It's particularly useful when data on post-manufacturing stages are limited or when the goal is to communicate the environmental impacts of manufacturing to business partners. ​

  Incorporating the cradle-to-gate methodology into EPDs is common, especially in sectors like civil infrastructure, where many EPDs focus on the impacts from raw material extraction to the point the product leaves the manufacturing gate.

Step 1: Define the Goal and Scope

• Objective: Clearly outline the purpose of the EPD. Whether it’s used for product improvement, market differentiation, or regulatory compliance, define the scope in terms of life cycle stages, geographical boundaries, and data sources.

• PCR Selection: Identify or develop relevant Product Category Rules (PCRs) that apply to your product group.

Step 2: Conduct a Comprehensive Life Cycle Assessment (LCA)

• Data Collection: Gather precise data covering all life cycle stages—from raw material extraction to disposal.

• Impact Assessment: Use standardized LCA methodologies to quantify environmental impacts, such as greenhouse gas emissions (GWP), energy consumption, water use, and waste generation.

• Verification: Engage qualified external experts for third-party verification of your LCA to ensure data integrity and methodological rigor.

Step 3: Document and Prepare the EPD

• Compile Results: Assemble the LCA findings into a coherent document following the ISO/EN guidelines.

• Disclosure: Include comprehensive information on assumptions, boundary definitions, and any limitations encountered during the LCA process.

• Transparency: Clearly communicate the data sources, methodologies used, and the rationale behind decisions in your EPD.

Step 4: Certification and Publication

• Third-Party Review: Submit the EPD for external verification under the chosen program—this could include national or industry-specific certification bodies.

• Registration and Publication: Once verified, register your EPD in recognized databases (such as the International EPD System) and publish it, ensuring easy stakeholder access.

Benchmarking and Comparative Analysis

• Establish Baseline Metrics:

  • Use historical EPD data to set internal benchmarks.

  • Compare environmental performance metrics against industry peers to identify where your products rank.

• Set Improvement Targets:

  • Incorporate benchmarking insights into target setting (e.g., reducing GHG emissions by X% relative to industry averages).

  • Use comparative analysis to drive product innovation and identify best practices within your market segment.

Data Quality and Life Cycle Assessment (LCA) Rigor

• Ensure Data Integrity:

  • Adopt standardized measurement protocols for collecting life cycle data.

  • Integrate advanced data management and LCA software to ensure repeatability and accuracy.

• Continuous Data Auditing:

  • Regularly review and update LCA inputs in line with evolving PCRs and technological advancements.

  • Establish a routine third-party audit schedule to maintain credibility and align with international standards.

Stakeholder Engagement and Transparency

• Comprehensive Documentation:

  • Provide detailed narratives on the methodologies, assumptions, and limitations within the EPD.

  • Develop a clear communication strategy to explain complex LCA data in layman's terms for diverse stakeholder groups.

• Feedback Loops:

  • Engage with stakeholders—including suppliers, customers, and industry peers—to gather feedback on published EPDs.

  • Use stakeholder insights to refine data collection, assumptions, and overall reporting practices.

Continuous Improvement and Market Integration

• Integrate EPDs into Product Development:

  • Embed EPD insights into R&D and product design, ensuring new or improved products are aligned with sustainability targets.

  • Use EPDs to inform supply chain optimization, such as selecting lower-impact materials.

• Leverage Digital Tools and Benchmarking Platforms:

  • Utilize digital platforms for managing, updating, and comparing EPD data. Such tools can help track improvements over successive product iterations.

  • Set up integrated dashboards that enable cross-product comparisons, making it easier to identify and disseminate best practices internally.

• Develop a Roadmap for Incremental Enhancements:

  • Create short-, medium-, and long-term plans based on benchmarking outcomes.

  • Align improvement milestones with broader corporate sustainability goals and investor expectations, ensuring that EPD progress is visible and quantifiable.

Common Challenges

• Data Complexity:

  • Ensuring comprehensive, high-quality LCA data is often resource-intensive and technically challenging.

• Methodological Variability:

  • Different PCRs and LCA methodologies can lead to inconsistent EPD outcomes, making inter-company comparisons difficult.

• Cost and Time Investment:

  • Developing a robust EPD requires upfront investment in expertise and third-party verification.

Opportunities

• Market Differentiation:

  • A well-developed EPD can serve as a marketing tool, showcasing your commitment to sustainability and providing a competitive edge.
