HotlineUnderstanding the definitions, timelines, and how TTS CERT helps businesses achieve accurate and fast results
In a global context where climate change is receiving unprecedented attention, transparency regarding the environmental impact of products has become more critical than ever. As consumers grow increasingly eco-conscious and regulatory bodies tighten oversight, the accuracy of environmental claims is being examined under a microscope. However, today’s market is becoming “distorted” by companies misusing the term Life Cycle Assessment (LCA) for superficial environmental evaluations.
This article aims to clarify the differences between Environmental Product Declaration (EPD), Product Carbon Footprint (PCF), and Life Cycle Assessment (LCA) — explaining why understanding these concepts is essential and helping businesses identify which environmental claims are trustworthy.
An Environmental Product Declaration (EPD) is an internationally standardized document that provides quantified environmental data about a product based on Product Category Rules (PCRs) — the common rule set for each product group. Developed according to international standards such as ISO 14025, an EPD presents the environmental performance of a product in a transparent and comparable manner. It includes various aspects such as carbon emissions, water consumption, and pollution, helping businesses communicate environmental information objectively and credibly.
The process begins with collecting input data (raw materials, energy, waste, etc.) and conducting a Life Cycle Assessment (LCA) in accordance with the chosen PCR. A background report details methodologies, assumptions, and applied standards, which is then verified by an independent third party following ISO 14025, ISO 21930, and ISO 14044. Once verified, the EPD is publicly published by a Program Operator.
Average completion time: over 4 months. EPDs enable manufacturers to transparently disclose the environmental impact of a product “from cradle to grave.” EPDs are increasingly required for green building, public procurement, and international environmental regulations.
The Product Carbon Footprint (PCF) represents the total greenhouse gas emissions generated throughout the entire life cycle of a product — from raw material extraction to end-of-life — expressed in CO₂ equivalent (CO₂e).
Define objectives – Why PCF is needed (benchmarking, reporting, hotspot identification, etc.).
Set system boundaries – Cradle-to-gate or cradle-to-grave.
Data collection – Primary data (from the company) and secondary data (emission factors).
Emission calculation – Activity data multiplied by emission factors to determine total CO₂e.
Average duration: 2–3 months. With TTS CERT: PCF can be completed much faster thanks to automated carbon-hotspot analysis tools.
PCF helps businesses identify major emission sources, develop reduction strategies, and progress toward Net Zero goals.
Life Cycle Assessment (LCA) is a comprehensive method used to evaluate all environmental impacts of a product or service throughout its entire life cycle — from raw material extraction, production, transportation, and use, to disposal or recycling.
Goal and scope definition – Purpose, target audience, functional unit, system boundaries.
Life Cycle Inventory (LCI) – Collecting and quantifying all material and energy flows.
Life Cycle Impact Assessment (LCIA) – Converting inventory data into impact indicators (CO₂, eutrophication, acidification, etc.).
Interpretation – Evaluating reliability, limitations, and suggestions for improvement.
LCA provides the most comprehensive environmental insight and is the foundation for developing EPDs or PCFs.
Criteria | EPD | PCF | LCA |
Purpose | Transparent disclosure of product environmental data | Total CO₂e emissions calculation | Comprehensive environmental impact assessment |
Standards | ISO 14025, EN 15804, PCR | ISO 14067, GHG Protocol | ISO 14040, ISO 14044 |
Scope | Defined by PCR for each product group | Greenhouse gases only (CO₂e) | All environmental aspects |
Verification | Mandatory third-party verification | Not required but recommended | Depends on objective |
Typical duration | ~4 months | 2–3 months | 2–3 months (depending on complexity) |
Deliverables | Official published declaration | Carbon emission report | Detailed life-cycle analysis report |
In an era where environmental sustainability is not just a trend but a requirement, distinguishing between EPD, PCF, and LCA is essential.
At TTS CERT, we significantly shorten assessment timelines — only 2–3 weeks for PCF and 2–3 months for LCA — while ensuring high accuracy and full compliance with international standards.
TTS CERT provides:
Expert guidance from specialists in LCA and PCF
Advanced Carbon Management software for fast and accurate calculations
Industry benchmarking & regulatory compliance support to ensure reliable disclosures
Whether you need PCF to identify carbon-reduction opportunities or LCA for a full environmental profile of your product, the TTS CERT team is ready to support you.
