In the realm of sustainable building and product transparency, Environmental Product Declarations (EPD) and Health Product Declarations (HPD) are two critical documents that serve distinct but complementary purposes. Both are essential for professionals seeking to make informed decisions about the environmental and health impacts of materials and products. This blog post will explore the key differences between EPDs and HPDs, their roles in sustainability, and their significance in the building industry.
An Environmental Product Declaration (EPD) is a standardized document that provides comprehensive information about the environmental impact of a product throughout its lifecycle. EPDs are developed based on international standards, such as ISO 14025 and EN 15804, ensuring consistency and reliability in the data presented.
Purpose and Use: EPDs are primarily used to provide transparency about the environmental impacts of products, enabling architects, engineers, and sustainability professionals to make more informed choices. They are crucial for achieving green building certifications like LEED and BREEAM, where points are awarded for using products with verified EPDs.
A Health Product Declaration (HPD), on the other hand, focuses on the health impacts of building products by disclosing their chemical ingredients and associated health hazards. HPDs follow the guidelines set by the Health Product Declaration Collaborative, ensuring consistency and reliability in reporting.
Purpose and Use: HPDs are used by architects, designers, and builders to ensure that the materials they select do not pose health risks to occupants. They are integral to creating healthier indoor environments and are often required for green building certifications like WELL and LEED, which emphasize human health and well-being.

Purpose and Audience:
In Saudi Arabia's major projects like NEOM and the Red Sea Project, EPDs (Environmental Product Declarations) and HPDs (Health Product Declarations) are used to enhance sustainability and health standards.
EPDs help assess and minimize the environmental impact of materials by providing detailed lifecycle data. This supports Saudi Arabia's goals for reducing carbon footprints and achieving environmental sustainability.
HPDs disclose chemical ingredients and associated health risks, ensuring that materials used are safe for occupants and workers. This aligns with the Saudi Arabia’s focus on creating healthier living environments.
Both declarations are integral to meeting international green building standards and aligning with Saudi Arabia's Vision 2030, which emphasizes sustainable development and environmental responsibility.
While both EPDs and HPDs play crucial roles in promoting sustainability and transparency in the building industry, they serve different purposes and provide different types of information. EPDs offer a comprehensive view of the environmental impacts of products, while HPDs focus on the health implications of their chemical ingredients. Understanding these differences allows professionals to make more informed decisions, ultimately leading to more sustainable and healthier building practices.
Incorporating both EPDs and HPDs into the decision-making process ensures a holistic approach to sustainability, addressing both environmental and health concerns. As the demand for transparency continues to grow, the importance of these declarations will only increase, driving the industry towards a more sustainable and health-conscious future.
