Closing the Loop: Understanding Environmental Product Declarations

The construction sector is accountable for a massive 80% of environmental impact in many fields. As awareness of sustainability grows, the imperative to make informed choices about building materials intensifies. Environmental Product Declarations (EPDs) emerge as a pivotal tool in this context. They offer a standardised method to evaluate the environmental footprint of products over their life cycle. This facilitates sustainable decision-making for manufacturers, architects, and designers.

This article will dissect the significance of EPDs, discuss their data interpretation, and highlight their advantages in the construction industry. Grasping the essence of EPDs enables us to strive for a sustainable built environment. It necessitates considering the full life cycle of the materials employed.

An Environmental Product Declaration (EPD) is a detailed, verified document. It sheds light on the environmental impact of a product from start to finish. This includes everything from raw material extraction to disposal or recycling. The aim of an EPD is to help manufacturers share the environmental footprint of their products. It also aids architects, designers, and other types of specifiers in making sustainable choices for construction projects.

EPDs are valid for five years but can be extended for another five if the manufacturing process remains unchanged. Over 250 EPDs have been published, with many more in development. They come in various types, catering to different needs and audiences.

Minor changes to EPDs, like colour variations, can be grouped together. However, each product’s environmental impact must be clearly stated. EPD operators can collaborate with other programs worldwide to ensure consistency and address new environmental challenges.

For products needing individual EPDs, generator tools offer a cost-effective solution. These tools allow for the creation of multiple EPDs with minimal input. EPDs are Type III environmental declarations, following ISO 14025. They provide standardised information on the life cycle impacts of a product.

EPDs are verified and registered independently, based on industry-standard product category rules (PCRs). They cover various impact categories, including global warming potential, ozone depletion, and acidification potential, among others.

In the U.K., EPD registries are managed by organisations like BRE Global, WRAP, and the Environment Agency. An EPD must comply with ISO standards and industry-standard PCRs. It requires third-party certification of the LCA process and a clear functional unit description. A comprehensive list of life cycle stages is also included.

EPDs facilitate comparisons between different flooring materials or suppliers. For instance, they can be used to evaluate Vinyl Tile against Ceramic Tile or to compare Reinforcing Steel #1 with Reinforcing Steel #2.

Environmental Product Declarations (EPDs) are crucial for the construction sector’s sustainable transformation. They offer detailed insights into the environmental footprint of building materials and products. This empowers architects, designers, and specifiers to choose materials that are better for the planet, people, and society.

The construction sector significantly impacts global environmental issues, using nearly half of the world’s raw materials and creating a third of global waste. This results in 40% of Earth’s carbon emissions. EPDs tackle these issues by encouraging the use of sustainable products. They push manufacturers to improve their processes and supply chains. This move supports a circular economy.

• By 2023, over 17,000 EPDs were published globally, showing rapid growth.

This helps businesses in making strategic choices for product development, material sourcing, and marketing. It aligns with their sustainability goals.

In conclusion, EPDs are key to the construction industry’s move towards sustainability. They empower stakeholders to make informed choices, encourage innovation, and support a circular economy.

EPDs might seem daunting at first, but they’re actually quite straightforward once you understand their structure. They provide a detailed look at a product’s environmental impact from start to finish. This includes everything from extracting raw materials to disposing of the product at the end of its life.

When looking at an EPD, there are several key sections to focus on:

• Product Description – This part describes the product, its composition, how it’s used, and any certifications it has.
• Life Cycle Stages – EPDs show the environmental effects of a product at different stages of its life, like when it’s made, transported, and disposed of.
• Environmental Impact Categories – These sections report on various environmental impacts, such as how much it warms the planet, depletes the ozone layer, and uses water. They give a full picture of the product’s environmental effects.

The data and metrics in an EPD might look complex, but they’re crucial for making choices that are good for the planet. The EPD data includes figures for environmental impact categories, like how much it warms the planet, harms the ozone layer, and uses water. Knowing how to read these EPD metrics helps us judge the environmental impact of a product. This way, we can pick materials for our projects that are better for the planet.

“EPDs offer a wealth of information to help us make sustainable choices, but it’s important to understand how to read and interpret the data they provide.”

Getting to know the layout and what’s in EPDs lets us use them fully. This way, we can make choices that are better for the environment when picking building materials and products.

EPDs prompt manufacturers to refine their processes and supply chains, fostering sustainable practices. This leads to the selection of products with reduced carbon footprints, increased recycled content, and enhanced end-of-life management. Such choices contribute to a more circular and sustainable built environment.

In 2022, the EPD platform’s Circular Economy Task Group was formed. Its goal is to standardise the assessment of products against circular principles. By early 2025, the task group aims to integrate circularity metrics into EPDs, deepening their connection to the circular economy.

Comparative studies have been undertaken to ensure the smooth integration of circularity metrics into EPDs. The Material Circularity Indicator by the Ellen MacArthur Foundation and the New Circularity Index by NLX and ICMQ have been evaluated. A pilot with a sliding door manufacturer showcased the usability and data collection capabilities of these methods.

There is a concerted effort to embed circular economy principles within EPDs, ensuring construction projects meet global sustainability benchmarks. Erco, a lighting manufacturer, has developed a guide for specifiers and lighting designers. It focuses on resource and energy consumption, as well as pollution impacts on air, soil, and water.

“EPDs are a standardised and internationally recognised form of environmental labelling for products, providing detailed environmental impact information of a luminaire.”

Erco has published EPDs for its product lines and introduced an eco-design protocol. This protocol demands products to endure 75,000 hours of continuous operation, equivalent to 20 years under typical use conditions.

The circular economy is essential for the built environment, and EPDs are pivotal in encouraging sustainable practices. They help align construction projects with global sustainability objectives.

Environmental Product Declarations (EPDs) bring numerous benefits but face challenges and limitations. The main issue is the availability and quality of data. The life-cycle assessment (LCA) process for an EPD is complex and requires significant resources. Manufacturers often find it hard to collect the needed information from their supply chains. Additionally, there are inconsistencies in the methodologies used across different EPDs.

EPDs are specific to individual products, making it hard to compare across categories or generalise findings. This lack of standardisation is a major challenge. Studies show that 3–12% of EPDs are not comparable even with the same Product Category Rule (PCR). Moreover, 73–87% are not comparable with different PCRs of the same product.

• Lack of harmonisation in EPD schemes due to differences in geographical scope, definitions, and vocabulary
• LCA modelling issues, such as poor inventory data and lack of common inventory databases, affecting the reliability and comparability of EPDs
• Variations in functional unit, cut-off rules, and system boundary leading to incomparable EPDs
• Increasingly narrow PCR scope posing challenges for achieving comparable EPDs

Standardisation and harmonisation efforts are vital to overcome these challenges. This is crucial for the widespread adoption and effectiveness of EPDs in the construction industry. Embodied carbon in buildings is a significant part of their greenhouse gas emissions.
