ENVIRONMENTAL PRODUCT DECLARATIONS (EPDs)
Following ISO 14025 for environmental labels and declarations, an Environmental Product Declaration (EPD) is a standardised, third-party verified document that clearly communicates the environmental performance or impact of a material or product over a given lifecycle boundary that is appropriate for the product.
Tunley helps you navigate the nuances of the EPD journey, from life cycle assessments to securing third-party endorsements, guaranteeing a declaration that's both thorough and verifiable.
UNDERSTANDING EPDs
An Environmental Product Declaration (EPD) is a comprehensive report that details the environmental impact of a product. It is essentially a product's carbon footprint calculated following standardised procedures for specific product types, known as Product Category Rules (PCR). The assessment, often referred to as a life cycle assessment or embodied carbon assessment, is validated by a third party to ensure comparability and reliability. Various organisations offer EPDs, and our preferred provider is the International EPD System, though we can collaborate with any EPD provider.
Clients may seek an EPD for various reasons, including regulatory and market-driven motivations:
Supply Chain Requirements: EPDs are often mandated by the supply chain, particularly in construction projects where environmental accountability is critical.
Quality Assurance: Seen as the "gold standard" of product carbon footprints, EPDs showcase a commitment to environmental responsibility and excellence.
Detailed Environmental Insights: EPDs are invaluable for clients interested in specific environmental impact categories, providing a clear and detailed analysis of their product’s environmental performance.

We have a team of PhD-Level Scientists with expertise in rigorous methodologies, assessments, and scientific processes.

We provide data as well as actionable reduction initiatives, ensuring a comprehensive and understandable carbon assessment report.

THE BENEFITS OF HAVING AN EPD
We offer complete life cycle assessments and embodied carbon assessments for products, providing clients with a detailed Tunley Report as the first step. Following this, we utilise SimaPro software to conduct a full environmental impact assessment, covering aspects like eutrophication and biogenic sequestration. This data is then formatted into an EPD following the specific Product Category Rules (PCR).
EPDs are recognised as accurate and truthful reflections of a product's carbon footprint, fostering consumer confidence.
They provide detailed data on various environmental impacts, such as eutrophication, offering a broader understanding of a product’s ecological footprint.
The third-party validation process ensures that the assessments are reliable and thorough, adding credibility to your sustainability claims.
An EPD signals to your stakeholders that your company is committed to transparency and environmental responsibility. This enhances your brand's credibility and sets you apart from competitors who may not have the same level of verified environmental data.
As the market shifts towards greater environmental accountability, having an EPD prepares your business for future regulatory changes and market demands. This proactive approach ensures long-term competitiveness and resilience.
