EPDs based upon Life Cycle Assessment (LCA) data

Sika publishes EPD for products across all its target markets

Sika has been publishing Environmental Product Declarations (EPDs) for its products since 2012 and its extensive EPD portfolio covers all its construction target markets, from roof to basement. EPDs are standardized documents used to communicate the potential environmental impacts and benefits of products throughout their life cycles based on quantitative Life Cycle Assessment (LCA) analysis. Sika companies provide EPDs based upon Life Cycle Assessment (LCA) data. They apply to products and product groups and may be used for sustainability assessment of the products and projects in which they are used.

What is an EPD?


Environmental Product Declarations, or EPDs for short, are a third-party verified and registered documents used to communicate the potential environmental impacts and benefits of products.  Creating an EPD is voluntary activity, and the scope of the EPD can vary depending on the amount of information a manufacturer wishes to disclose. EPDs can be narrow in scope, covering the product stage only (“Cradle to Gate”), or can include the entire product life cycle (“Cradle to Grave”).


The relevant standard for Environmental Product Declarations is ISO 14025, which defines EPDs as "Type III Environmental Declarations". A Type III Environmental Declaration is developed and registered within the framework of an EPD program, such as the British Building Research Establishment (BRE) or German Institut "Bauen und Umwelt" (IBU), among others. All EPDs registered with an EPD program are made publicly available on the program’s website and can also be listed on the ECO Platform in Europe.


What does an EPD contain?

The EPD contains information about the product and its potential environmental impacts and benefits:

  • Technical information: Relevant product data and information
  • LCA information: Environmental impacts, e.g. Global Warming Potential, Cumulative Energy Demand, Acidification Potential, but also a description of the LCA process (data, methods, assumptions)
  • Other relevant measurements (e.g. VOCs, haz-mats, etc.)
  • Review and verification information: Information on the LCA consultant and the EPD program operator, and the external 3rd party EPD verifier



An EPD may be used for many different applications, including green public procurement (GPP) and building assessment schemes. The concept of Type III Environmental Declarations was developed to primarily be used in business-to-business communication, but their use in business-to-consumer communication is not precluded by the standards.

EPDS by Sika

Admixtures and EPDs 

In the area of admixtures that help customers design better mixes Sika offers the industry’s first effective technology to instantly verify improved environmental performance. Sika’s Rapid line of hardening accelerators allow customers to utilize a greater percentage of SCMs and improve speed of construction by increasing early age strength gain so that forms can be turned quicker and structure elements can support construction loads sooner. Sika® EPD NOW will instantly create a verified  EPD for such mix designs.

Model EPD's

Industry associations are also active in the EPD space and have developed Model EPDs which can be used by member companies. For instance, the European Federation of Concrete Admixtures Associations (EFCA) and the European Adhesive and Sealant Industry (FEICA) have both developed a range of Model EPDs for admixture and  resin-, dispersion- and cementitious-based products, respectively. These Model EPDs have been third-party verified to be in conformity with international standards EN 15804 and ISO 14025 and have been published by the Institute for Construction and Environment in Germany (IBU).  All Sika member companies of these associations have the right to declare that a specific Model EPD applies to a given product if an assessment of the formulation has been completed in accordance with the IBU-approved guideline procedure for the relevant product category.
