Currently, the global construction industry is placing greater emphasis on the concept of Sustainability and reducing environmental impacts. One of the key tools that helps ensure the selection of construction materials is based on transparent and verifiable information, which is the EPD (Environmental Product Declaration). EPD is an internationally recognized environmental label that provides information on the environmental impact of products throughout their entire life cycle, from production, transportation, and usage to end-of-life management. For this reason, EPD has become essential information that project developers, architects, and construction material manufacturers use to make decisions in modern design and construction.
What is EPD (Environmental Product Declaration)
EPD (Environmental Product Declaration) is a document or label that presents information regarding the environmental impact of a product, using a principle of analysis known as Life Cycle Assessment (LCA)
. The LCA assessment analyzes the impacts of a product from
- raw material acquisition
- , production processes,
- transportation and usage,
- to disposal or recycling after the end of its life cycle.
The information in an EPD typically covers key indicators such as
- greenhouse gas emissions (Global Warming Potential)
- , energy and natural resource consumption,
- waste generated from production processes,
- and impacts on ecosystems.
Importantly, EPDs must undergo verification by independent third-party organizations to ensure the information is credible and can be compared across products.
relevant standards for EPD such as
- ISO 14025
- EN 15804 (for construction materials)
Why is the EPD label important in the construction industry
1. Increases environmental transparency of materials
In the past, the selection of construction materials often focused primarily on price, quality, and durability. However, today project developers are beginning to prioritize the environmental impact of materials
EPD enables
- comparison of materials from multiple manufacturers
- assessment of environmental impacts
- selection of materials that align with sustainable construction concepts
2. Supports green building standards
Many construction projects aim to meet green building standards such as
- LEED (Leadership in Energy and Environmental Design)
- TREES (Thailand Rating of Energy and Environmental Sustainability)
- WELL Building Standard
Materials with EPD information can help projects earn environmental credits in these assessment systems thus making this type of information increasingly important in the building design process
3. Helps reduce carbon in the construction industry
The construction industry is one of the sectors that emits a significant amount of greenhouse gases globally
Data from EPD can be used to analyze Embodied Carbon or the amount of carbon generated from the production of construction materials, which helps architects and engineers
- design low carbon buildings
- select materials with lower environmental impact
- support Net Zero Carbon goals
Why construction material manufacturers prioritize EPD
to enhance product credibility EPD provides transparent and independently verified environmental information about products, thereby helping to build credibility for products in the market
increase opportunities to participate in green building projects
Many construction projects, especially large-scale projects or those requiring green building standards, often prioritize materials with environmental data, such as EPD. Therefore, construction material manufacturers are beginning to develop EPD to meet the changing market demands Examples of product development guidelines that consider environmental data
Why architects and designers use EPD data
For architects, data from EPD is one of the essential tools for designing sustainable buildings as it helps to
- analyze the environmental impact of materials
- select materials that align with the Green Building concept
- plan designs to reduce the carbon emissions of buildings
It is therefore not surprising that EPD has become increasingly used in the design process of modern buildings
Trends of EPD in the construction materials industry
The trend of the global construction industry is moving towards transparency in environmental data of products
Many countries are beginning to emphasize
- the disclosure of carbon data of materials
- reducing Embodied Carbon
- developing environmentally friendly buildings
EPD is therefore likely to become an important standard for construction materials in the future
FAQ Frequently Asked Questions about EPD labels
Q1: How does EPD differ from general environmental labels?
A1: EPD is a label that displays quantitative data from Product Life Cycle Assessment (Life Cycle Assessment) and must be verified by an independent agency, making it transparent and comparable between products, unlike some types of environmental labels that may only certify certain attributes.
Q2: How is EPD related to carbon reduction?
A2: The data in EPD helps analyze the carbon emissions from material production (Embodied Carbon) which is crucial information for designing buildings that aim to reduce greenhouse gas emissions and support the Net Zero Carbon goal.
Q3: What types of construction materials have EPD?
A3: Currently, there are various types of construction materials that can have EPDs, such as concrete, steel, glass, insulation, and building paints. Market trends have led many material manufacturers to begin producing more EPDs.
Q4: Is EPD important for green building standards?
A4: EPD provides information that supports building assessments in green building standards such as LEED and TREES as it allows projects to transparently present the environmental impact data of the materials used in buildings.
Q5: Do general consumers need to pay attention to EPD?
A5: Although EPD is widely used at the project and construction industry level, general consumers who want to choose environmentally friendly materials can use information from EPD as one of the factors in their decision-making.
