If you’re working in sustainable construction, chances are you’ve come across EPDs, LEED, and BREEAM—but how do they actually connect?

Whether you’re an architect designing for a green certification, a product manufacturer entering sustainable markets, or a consultant navigating documentation, understanding the relationship between Environmental Product Declarations (EPDs) and green building certifications can make a major difference in project outcomes.

Let’s break it down.

What’s an EPD?

An Environmental Product Declaration (EPD) is like a nutrition label for building materials—but instead of calories and fat, it shows things like:

  • Carbon footprint (Global Warming Potential)
  • Energy use
  • Water consumption
  • Waste generation

EPDs are based on Life Cycle Assessments (LCAs), follow strict international standards (like EN 15804 or ISO 14040/ISO 14044), and are third-party verified (ISO 14025).

That means they’re reliable and comparable, making them extremely useful in green building rating systems.

LEED & EPDs: Where They Fit

In LEED v4 and v4.1, EPDs contribute to the Materials and Resources (MR) credit called: Building Product Disclosure and Optimization – Environmental Product Declarations

You can earn up to 1 point by including at least 20 permanently installed products from at least 5 manufacturers that have EPDs. Here’s the catch:

  • Product-specific EPD = 1 product counted
  • Industry-wide EPD = 0.5 product counted

If you’re a manufacturer, having a product-specific EPD increases the value of your product in LEED projects.

BREEAM & EPDs: Going Deeper into LCA

BREEAM, widely used in the UK and Europe, focuses more on whole-building life cycle assessment and uses EPDs to improve the accuracy of those assessments. EPDs contribute to these credits:

  • Mat 01 – Life Cycle Impacts: Using EPD-backed data in your building’s LCA improves the overall sustainability score.
  • Mat 02 – Environmental Product Declarations: BREEAM awards points for using products with verified EPDs. More EPDs = more credits.

EPDs from programs like IBU, The International EPD System, or BRE are fully recognized.

Why EPDs Matter for Certification

BenefitLEED ImpactBREEAM Impact

Competitive edgeProduct-specific EPDs carry more valueHigher credit value than generic data
Embodied carbon trackingHelps meet project-level climate targetsAligns with net-zero and circular economy

So, What’s the Takeaway?

If you’re aiming for LEED or BREEAM certification, choosing products with EPDs gives you a measurable advantage—not only in points but in credibility, transparency, and alignment with long-term sustainability goals.

And if you’re a manufacturer? Publishing a verified EPD makes your product more attractive in the growing green construction market.

Final Thoughts

In a world increasingly focused on low-carbon buildings and material accountability, EPDs are more than paperwork—they’re your passport to sustainable success.

Thinking of creating or using EPDs for your next project? Let’s talk—we’d love to help you navigate the process and unlock the potential of sustainable product choices.
