An environmental product declaration (EPD) is a standardized document that transparently reports the environmental impacts of a product throughout its life cycle. It is developed in accordance with ISO 14025, which sets the rules for Type III EPDs. An EPD is based on a comprehensive life cycle assessment (LCA), evaluating impacts such as energy use, emissions, and resource consumption from raw material extraction through disposal.

A manufacturer would need an Environmental Product Declaration (EPD) to transparently report the embodied carbon and overall environmental impact of their products using standardized, third-party verified data. EPDs are powerful marketing tool, helping manufacturers gain a competitive advantage and demonstrate environmental responsibility in sustainability-focused markets. They are useful for government or corporate procurement requirements that demand verified sustainability information.

The timeline to develop an Environmental Product Declaration (EPD) can range from 3 months, depending on the complexity of the product and the availability of life cycle assessment (LCA) data. The process includes data collection, LCA modeling, report preparation, and required third-party verification to ensure accuracy and compliance with program standards. Products with well-organized data and prior LCA experience may move through the process more quickly, while more complex products can take longer.

To create an Environmental Product Declaration (EPD), detailed LCA data (Life Cycle Assessment data) is required to evaluate the environmental impacts of a product across its entire life cycle. This includes manufacturing inputs such as raw materials, transportation, and processing details, as well as comprehensive energy data covering electricity and fuel use during production. Additional information on emissions, waste generation, and end-of-life scenarios is also typically needed to ensure accurate and transparent reporting.

A Life Cycle Assessment (LCA) is a quantitative methodology, standardized under International Organization for Standardization ISO 14040/ISO 14044, that evaluates the environmental impacts of a product system across its life cycle (cradle-to-grave or cradle-to-gate). An Environmental Product Declaration (EPD), governed by ISO 14025, is a third-party verified, standardized disclosure document that reports LCA results and other prescribed information according to product category rules (PCRs). In short, the LCA is the analytical study, while the EPD is the externally verified communication of those results in a comparably structured format.

An Environmental Product Declaration (EPD) creates a competitive advantage by providing verified supply chain transparency, giving customers clear, comparable data on a product’s environmental impact. This transparency builds trust, strengthens brand credibility, and differentiates offerings in increasingly sustainability-driven markets. EPDs also position companies to win projects tied to low-carbon procurement requirements, helping business development teams access new revenue streams and meet the growing demand for measurable climate performance.

Yes—an Environmental Product Declaration (EPD) can meaningfully support ESG reporting by providing verified, product-level data on environmental impacts across the full life cycle. This includes quantified greenhouse gas data that helps organizations better understand and disclose Scope 1, Scope 2, and Scope 3 emissions, particularly within complex supply chains. For executives, EPDs enhance transparency, improve the credibility of sustainability disclosures, and strengthen alignment with investor and regulatory expectations.

Manufacturing industries interested in showcasing their production energy savings and overall environmental impact will benefit from their products having Environmental Product Declarations (EPDs). Interest began with manufacturers tied to the construction industry, including HVAC and lighting manufacturers pursuing the goal of MEP 2040. However, a range of other industries are engaging to demonstrate a competitive edge using EPD documentation -- packaging manufacturers, manufacturers of aviation-related products complying with the European Union Carbon Border Mechanism (CBAM), multi-national health industry manufacturers supporting the Belém Health Action Plan for the Adaptation of the Health Sector to Climate Change that came out of COP30, etc. These declarations help all of these industries quantify and communicate their environmental performance and competitive edge more effectively.

Yes, EPDs (Environmental Product Declarations) are increasingly required in government and institutional projects where public procurement policies include sustainability requirements. Many public sector tenders now mandate EPDs to demonstrate the environmental impact of products, helping agencies meet carbon reduction and sustainability targets. Vendors bidding for these projects should be prepared to provide verified EPDs to comply with these criteria. This ensures transparency and supports greener procurement practices.

E6 Analytics is a recognized referral partner of One Click LCA and has the expertise to analyze a product's fabrication process, author an EPD and guide the EPD through its third-party validation and publishing, after which it is available to LCA libraries for customer comparison against lower performing competitors. We work in a wide range of industries and product types.

One Click LCA is a life cycle assessment (LCA) software platform that automates the calculation of environmental impacts for buildings, construction products, and infrastructure. It is widely used in Environmental Product Declaration (EPD) development to quantify and document the embodied carbon, energy use, and other environmental indicators of products according to international standards such as ISO 14025 and EN 15804. By integrating product-specific data with global LCA databases, it streamlines compliance, benchmarking, and reporting processes for manufacturers and construction professionals. Its automated workflows reduce manual errors and accelerate the creation of verifiable EPDs.

Developing an Environmental Product Declaration (EPD) involves costs for data collection, lifecycle assessment, and third-party verification to ensure accuracy and credibility. Additional expenses arise from the publishing process, including registration with program operators and ongoing updates. These costs vary by product complexity, scope, and verification requirements but are essential for maintaining compliance and market credibility.

An Environmental Product Declaration (EPD) must be updated at least every five years to ensure it reflects current production processes, materials, and environmental impacts. Updates may also be required sooner if there are significant changes in the product formulation, manufacturing methods, or relevant regulations. Regular updates help maintain transparency and compliance.

Manufacturing energy performance directly influences Environmental Product Declaration (EPD) results because higher energy intensity typically leads to increased greenhouse gas emissions during production. Efficient energy use reduces both the energy demand and associated process emissions, thereby lowering the overall environmental impact reported in the EPD. Optimizing manufacturing processes can therefore improve EPD outcomes by minimizing both direct and indirect emissions.

Smaller manufacturers can justify the cost of an EPD since it is an investment that enhances the ROI through expanded market access, especially in sectors where sustainability credentials are increasingly required. For SMBs, the upfront cost may be offset by opportunities to enter new markets, meet customer sustainability demands, and differentiate from competitors. The long-term benefits in credibility and sales potential outweigh the investment. Strategic planning and targeting high-value customers make EPD adoption cost-effective for smaller operations.
