Environmental Product Declaration

An Environmental Product Declaration (EPD) is a voluntary declaration that provides quantitative information about the environmental impact of a product, using life-cycle assessment (LCA) methodology and verified by an independent third party. It provides a clear, consistent, and transparent basis for reporting broad environmental performance for similar types of materials or products.

EPDs have to meet and comply with specific and strict methodological prerequisites, such as comparisons for different products, and the ability to aggregate these declarations for multiple materials in the supply chain. To achieve this goal, common calculation rules, known as Product Category Rules (PCRs), are established to ensure that standard procedures are used when creating EPDs for similar products.

EPDs are based on PCRs which are established to ensure that EPDs within a similar product type are constructed from comparable data and analysis methods. A product category is a group of products that can fulfill equivalent functions. Once the key attributes of a product’s manufacturing impacts are identified by the PCR, data collection and assessment through the life cycle assessment process becomes more efficient, consistent and cost effective. To ensure credibility, the rules are prepared with input from a wide range of stakeholders to achieve consensus.

EPD have been used for construction products since the first environmental assessment schemes were developed in the 1990s, and an ISO standard for EPD (ISO 14025:2006) sets out the standards they should meet.

Product Category Rules (PCR) for concrete

EPD_PCR_cover

The CSI developed Product Category Rules (PCR) for unreinforced concrete, the common methodology underlying the issuance of an EPD. The CSI PCR is registered under the International EPD System® for use by companies worldwide.

The CSI PCR is based on the ISO standard for EPD (ISO 14025:2006) and complies with the European standard for construction products, EN 15804:2012 that sets the core rules for EPDs for construction products. It also takes into account standard developments in other regions, particularly the US.

PCRs are vital to the concept and practice of EPDs. They establish the assumptions, scope and functional units (e.g. kg or m2), meaning that manufacturers cannot alter them in order to favor their products. EPD can only be compared when the same PCR have been used, ensuring the methodology, data quality and indicators are consistent, and that all the relevant life cycle stages have been included.

CSI EPD tool for cement and concrete

CSI EPD tool for cement concreteThe CSI EPD Tool was developed to facilitate the generation of sector-specific EPDs for cement and concrete but also for clinker, lime and plaster. The cloud-based tool was designed to be easy-to-use, to facilitate the process overall, and to reduce the costs of preparing cement and concrete EPDs.

Joining hands with the Portland Cement Association (PCA), a customized version was developed to include reference PCRs for cement and concreate specific to the US.

More consistency across industry reports
  • Methodology and basic LCA data are common
  • Produces more reliable benchmarking
  • Carbon footprint can be extracted
Reduced time and costs for EPDs
  • Easy to use – on line training available
  • Significant LCA consulting cost eliminated
  • Reports are automatically generated
 Pre‐verified tool
  • Streamlined process
  • Pre‐verification ‐ reduce time & cost for 3rd party verification
  • Pre‐verification recognized by main program operators (Environdec, IBU,..)
 Applicable worldwide
  •  Mutual recognitions of program operators

By using the same set of underlying standard across its operations globally, companies demonstrate enhanced credibility on product information. At the same time, the flexibility of the tool allows local adaptation to applicable laws and industry practice in different regions (e.g. treatment for allocation of slag), thus enhancing the applicability of the tool under different context, without jeopardizing the overall consistency of its methodological basis.
