How to Make an EPD: A Practical Guide for Concrete Producers

Environmental Product Declarations (EPDs) are now widely required in construction and materials markets. But for many concrete producers, the process feels confusing, risky, and harder than it should be.

That’s usually not because EPDs are complicated. It’s because the way they are created introduces unnecessary risk. This guide explains, step by step and in plain language, how to make an EPD using Climate Earth’s approach. Each step explains:

• what happens,
• why it matters, and
• what can go wrong if it’s done differently.

No prior EPD or LCA knowledge required.

What Is an EPD?

An Environmental Product Declaration (EPD) is a verified document that shows the environmental impacts of a product, such as its carbon footprint.

To create a credible EPD, someone must:

• choose the right production data,
• apply the correct calculation rules (called Product Category Rules or PCRs), and
• prove the results are accurate through independent third‑party verification.

If any of these steps are weak, the EPD can be delayed, rejected, or misleading.

Step 1: Verify the Plant, Not Just One Mix.

Climate Earth starts by verifying the production plant. This includes reviewing:

• raw materials,
• energy and fuel use,
• transport distances, and
• production processes.

Once verified:

• the plant is approved for EPD creation, and
• you can create unlimited, verified EPDs for different mixes produced at that plant instantly.

Why this matters: Concrete mixes change often, but the plant does not.

What goes wrong without plant‑level verification? If EPDs are verified one mix at a time:

• each new mix takes longer and costs more,
• assumptions are reused inconsistently, and
• results across products become harder to defend.

Plant‑level verification creates a stable, consistent foundation.

Step 2: Experts Collect and Interpret Your Data. This is necessary for accuracy.

Climate Earth does not rely on fully automated data collection. Instead, experienced Climate Earth experts work directly with your team to collect data from your existing QC systems and production records. They actively review:

• whether data is complete,
• whether values are realistic,
• how missing data should be handled,
• how materials and energy should be allocated, and
• whether assumptions meet EPD and PCR rules.

Why this matters: QC systems are designed to control production, not to produce EPD‑ready data.

Why automated data collection is risky? When data is pulled automatically without expert interpretation:

• missing data may be treated as zero or ignored,
• plant‑specific context is lost,
• incorrect assumptions are baked into calculations, and
• errors can scale across many EPDs before being noticed.

These issues often surface late — during verification or customer review — when they are expensive and time‑consuming to fix. Human expertise at this stage prevents errors from entering the system at all.

Step 3: Software Validates the Method and Consistency

After expert review, Climate Earth’s software:

• applies the correct EPD calculation rules,
• checks units and ranges,
• ensures consistent methodology across mixes, and
• flags missing or inconsistent inputs.

EPDs are created and stored in Climate Earth’s platform — not inside QC systems — ensuring an auditable, controlled environment.

Why this matters: Humans provide judgment; software provides consistency.

What goes wrong without this step? Without software validation:

• small inconsistencies grow over time,
• different products follow different methods, and
• errors become difficult to trace.

This creates a second, essential layer of protection.

Step 4: Independent Third‑Party Verification — Verifying the Whole Plant

Independent third‑party verification is a required part of every EPD. Climate Earth handles this process for you and ensures the verifier reviews:

• the plant data and assumptions,
• how data is handled and validated in the Climate Earth system,
• the calculation methodology, and
• the final EPD results.

This means the verifier is reviewing the entire EPD process at the plant, not just a single document. Once verification is complete:

• the plant is verified,
• the system and methodology used at that plant are approved, and
• EPDs created from that plant are based on a trusted framework.

Why this matters: This approach reduces rework, delays, and risk when creating future EPDs.

Step 5: You Get Instant EPD Software — After the Plant Is Verified

Once third-party verification is complete, Climate Earth provides access to its EPD software for that verified plant. Our software allows you to:

• instantly create EPDs for current and new mixes produced at the verified plant,
• update EPDs when mix designs change, and
• maintain consistency across all products from that plant.

The key point: the heavy work has already been done. The plant, data structure, and methodology have been reviewed and approved by a third-party verifier.

Why this is powerful: In most EPD processes, creating a new EPD means starting over: collecting data again, rebuilding models, and re-entering verification. With Climate Earth:

• the verified plant becomes an approved EPD environment,
• the software applies the same verified rules every time, and
• new EPDs can be generated quickly without redoing foundational work.

This turns EPD creation from a slow, manual project into an operational capability.

What goes wrong without this model? Without plant-level verification and software support:

• every new mix triggers new consulting work,
• turnaround times remain slow,
• costs grow linearly with the number of EPDs, and
• producers hesitate to update EPDs when mixes change.

Climate Earth’s approach lets concrete producers respond quickly to bids, specifications, and customer requests. Without sacrificing accuracy or credibility.

Summary: Why This Approach Works Best in Practice

Making an EPD is not about clicking a button. It is about managing risk. Climate Earth’s approach combines:

• plant‑level verification,
• expert‑led data interpretation,
• software‑based validation, and
• independent third‑party review.

Together, these steps produce EPDs that are accurate, defensible, scalable, and trusted by specifiers, regulators, and customers.

For concrete producers, this means fewer surprises, faster approvals, and EPDs that reflect how your plant actually operates.
