Navigating the Standards

Standards: A gateway to sustainability* ​

​Navigate the complexity of standards governing the embodied carbon of products, tailored specifically for the MEP (Mechanical, Electrical, and Plumbing) industry. ​

This page serves as a springboard as a simplified overview between standards and topics.

It is an introductory resource, offering a streamlined overview of international and regional standards pertinent to measuring and communicating embodied carbon.​



It covers MEP product standards related to life cycle assessments (LCA), environmental product declarations (EPD), product category rules (PCR), and product carbon footprints (PCF). These standards are crucial for empowering you to quantify, report, and champion the environmental performance of products across diverse markets.​ 

Let's start with an overview...

The following tables provides a high-level overview of some key standards that are relevant for calculating and communicating the embodied carbon of products. ​

The standards are organized by scope, indicating its relevance to products or the building; and by topic, indicating its relevance to LCA, EPD, PCF, or PCR.

Understanding the inter-relationship between standards

Understand how the standards relate to one another. Our diagram illustrates that product embodied carbon may be determined via different pathways and PCRs:​

Each PCR may define different impact categories and life cycle stages which makes it difficult to make comparisons between products that use different methods.​

The diagram also captures some examples of regional/national variants that may further refine the product category rules using product specific rules (PSR). The PSR allow tailoring towards more specific product categories, for example, Fire Safety Systems.

EPD and PCF Coverage

Our diagram illustrates how the product carbon footprint (ISO 14067) covers a subset of the impact categories that are addressed within the scope of an environmental product declaration (ISO 14025).

Now the detailed list of standards…

For more context on how these standards relate to MEP products, the following table presents the outline of the standard, and where relevant, provides additional references to national guidance such as BSI PAS.
