Product Health Declaration

PHD Certificate

The Product Health Declaration (PHD) certificate is similar to HPD (Health Product Declaration) and a comprehensive tool designed to provide transparent, detailed information about the health impacts of products, particularly in the green building industry. This certification is crucial for ensuring that products meet specific health and environmental standards, offering a benchmark for safety and sustainability. The PHD certificate is recognized globally and aligns with various building standards, including WELL™ and LEED®.

Importance of PHD Certificates

PHD certificates represent a significant advancement in the realm of product health certification, going beyond the traditional focus on individual ingredient hazards to also consider the health impacts of the final product. This comprehensive approach ensures that products are not only assessed for potential risks during manufacturing but also for their long-term effects on human health. The PHD certification process addresses a broad spectrum of health concerns related to toxic ingredients, such as cancer, hormone disruption, asthma, and allergies.

The holistic assessment inherent in PHD certificates provides a more detailed and accurate picture of product safety. Traditional certification methods often concentrate on the hazardous properties of individual ingredients, sometimes neglecting the cumulative health effects when these ingredients are combined in a finished product. PHD certificates rectify this by requiring manufacturers to disclose the complete list of ingredients and assess their combined health impacts. This transparency is critical for identifying and mitigating risks associated with toxic substances that can lead to serious health issues like cancer and endocrine disruption, which can cause significant long-term health problems.

Moreover, the stringent criteria set by PHD certificates encourage manufacturers to reformulate their products using safer alternatives. This proactive approach not only enhances the safety of products but also promotes innovation in developing healthier materials. By addressing concerns such as respiratory issues, allergies, and chronic illnesses linked to chemical exposures, PHD certifications help create a safer environment for consumers. For instance, the presence of volatile organic compounds (VOCs) in building materials has been linked to asthma and other respiratory problems. By adhering to PHD certification standards, manufacturers are incentivized to reduce or eliminate VOCs from their products, thus contributing to healthier indoor air quality and overall well-being.

The impact of Product Health Declaration certificates extends beyond individual health, influencing broader environmental and economic factors. Products that meet PHD standards are often associated with lower environmental toxicity, contributing to sustainable practices and reducing the ecological footprint. Additionally, healthier products can lead to significant economic benefits, particularly in workplace settings. Studies have shown that the use of low-toxicity products in office environments can reduce employee absenteeism and increase productivity, translating to substantial cost savings for businesses. For example, a study by Sustainability Victoria demonstrated that retrofitting offices with low-toxicity products reduced sick leave by 30% and boosted productivity by 45%.

In conclusion, PHD certificates play a crucial role in advancing product health and safety by requiring comprehensive disclosure and assessment of both ingredients and final products. This ensures that products are safer for use, addressing a wide range of health concerns and promoting innovation in healthier product development. The benefits of PHD certification are far-reaching, enhancing individual health, supporting sustainable practices, and providing economic advantages through improved workplace environments.

Key Features of PHD Certificates

Transparency and Disclosure: PHD certificates require full disclosure of product ingredients down to 100 parts per million (ppm), ensuring that all potential hazards are identified and assessed.

This level of transparency helps consumers and professionals make informed decisions about the products they use, reducing risks associated with toxic substances.

Alignment with Health Standards: PHD certificates are aligned with the WELL™ Building Standard and LEED® Product Disclosure Credits, making them an integral part of green building certification processes.

The certification covers several WELL features, including VOC Reduction, Fundamental Material Safety, Enhanced Material Safety, and Material Transparency

Health Impact Assessment: The PHD process involves rigorous health impact assessments using tools like GreenScreen® for Safer Chemicals, which classify chemicals based on their hazards and provide a benchmark score for each substance.

This assessment helps in identifying safer alternatives and encourages manufacturers to improve the healthiness of their products.

Benefits of PHD Certificates 

For Manufacturers: Achieving a PHD certificate can differentiate products in the marketplace, showcasing a commitment to health and sustainability. It provides a competitive edge, particularly in markets that prioritize green and healthy building materials

For Consumers: PHD certificates offer peace of mind by ensuring that products are safe for use, based on comprehensive health assessments and transparency in ingredient disclosure. Consumers, especially those with specific health concerns, can make informed choices about the products they bring into their homes and workplaces

For Building Professionals: PHD certificates support building professionals in selecting products that are safer for human health, reducing risks associated with toxic materials in building environments. They facilitate compliance with building standards and contribute to healthier indoor environments, which can enhance occupant well-being and productivity.

GreenTag  PHD Certificate

The GreenTag PHD is an example of a PHD certificate that has been recognized for its rigorous standards and global relevance. It is compliant with WELL™ and LEED® standards, providing a clear measurement of the healthiness of products through the GreenTag HealthRATE™ mark. This mark ranges from Bronze to Platinum, indicating the varying levels of healthiness of certified products.


Greentag Certification Levels

GreenTag PHD certificates also emphasize the importance of reducing toxic ingredients in products, which can have significant health impacts on building occupants. For instance, studies have shown that using healthier products in buildings can reduce sick leave and increase productivity, highlighting the tangible benefits of such certifications

The PHD certificate is a vital tool for ensuring product health and safety, particularly in the green building industry. By requiring detailed disclosure of ingredients and rigorous health impact assessments, PHD certificates help manufacturers, consumers, and building professionals make informed decisions about the products they use. This transparency and commitment to health ultimately lead to safer, healthier environments for all.
