Life Cycle Assessment (LCA) is becoming a central aspect of construction work. As the focus increases on tackling environmental challenges and minimizing carbon footprint across all industries, finding innovative and measurable ways to mitigate their environmental impact is becoming essential. Not just to meet regulatory demands, but to remain competitive in an increasingly eco-conscious market as well. In the construction industry, LCA has become the key to honing in on specific environmental challenges throughout the entire lifespan of a construction project, from cradle to grave.

LCA for construction has a foundation in many different international and local standards, certifications, and guidelines that form a legal and regulatory context and framework for it. In this article, we aim to explore the key standards associated with LCA and touch on international initiatives and environmental pledges within the Nordic countries and the EU, particularly for milestone years like 2030 and 2050.

International ISO standards for LCA

Several key ISO standards influence the shape and focal points of LCA for construction. Among them are standards that aim widely to form frameworks and structure for the process of LCA, while others focus on specific stages and areas, or target related industries such as mineral extraction or logistics.

The principles of LCA – ISO 14040 and ISO 14044

These standards are foundational international standards that provide principles and a framework for conducting LCA. ISO 14040 outlines the principles and framework for conducting LCA, emphasizing the importance of a systematic approach in evaluating the environmental aspects and potential impacts throughout a product’s life cycle. For the construction industry, this entails defining the stages and phases of LCA. ISO 14044 specifies the detailed requirements for performing each stage of the LCA process, ensuring a comprehensive and standardized methodology.

Together, these standards provide a foundation for performing LCA studies with consistency and reliability. They help to establish how to quantify and measure the environmental impact of various materials, processes, and practices while fostering a global understanding of these impacts.

What does ISO 14025 mean in the context of LCA?

ISO 14025 establishes the principles and procedures for developing Type III environmental declaration programs, and Type III environmental declarations. This is the foundation for the Environmental Product Declaration (EPD) which, in the context of the construction industry, provides important data on the environmental impact of products and materials. EPDs communicate the environmental performance of products based on LCA results, offering transparency to consumers and decision-makers. The ISO 14025 standard establishes the core requirements for creating EPDs, ensuring consistency and reliability in the information communicated. By encouraging the use of EPDs, ISO 14025 contributes to the broader goal of promoting sustainable consumption and production patterns, guiding industries and consumers toward environmentally friendly choices in construction materials and products.

EDP is defined by ISO 15804

This standard specifically targets construction products, providing the principles, specifications, and requirements to develop EPD for the construction industry. ISO 15804 facilitates the evaluation of the total environmental impact of each product and material from raw material extraction to final disposal. By providing a standardized methodology, ISO 15804 promotes transparency and comparability in assessing the environmental credentials of construction products, empowering stakeholders to make informed decisions that align with sustainable practices for the built environment.

The foundation for LCA in the construction industry

In essence, these international standards collectively provide a comprehensive framework, ensuring the reliability, consistency, and comparability of LCA studies. They not only facilitate the adoption of sustainable practices in the construction industry but also contribute to a global understanding of environmental impacts across diverse sectors, fostering a more environmentally conscious and responsible approach to decision-making and development.

What Certifications and Guidelines are related to LCA

Where the ISO standards form the foundation for LCA, there are certifications and guidelines where LCA serves as part of a foundation to ensure a systematic and transparent approach to environmentally conscious construction practices. The most known ones among these are LEED and BREEAM. Additionally, different national guidelines are worth mentioning, such as those for the Nordic countries.

What is LEED in relation to LCA?

Leadership in Energy and Environmental Design (LEED), developed by the U.S. Green Building Council, stands as a preeminent certification system that integrates LCA principles into the evaluation of the environmental performance of buildings. LEED certification encompasses a comprehensive set of criteria, covering aspects from energy efficiency to sustainable materials. LCA is particularly emphasized in the Materials and Resources category, where projects earn points for utilizing environmentally preferable products, which are often determined through life cycle considerations. LEED's influence extends beyond the United States, shaping global perspectives on sustainable construction.

What is BREEAM in relation to LCA?

Building Research Establishment Environmental Assessment Method (BREEAM) is a widely recognized and utilized certification system for evaluating the sustainability of buildings through a holistic approach. BREEAM places a strong emphasis on environmental performance, including life cycle considerations of products. BREEAM encourages the use of products with low environmental impact and emphasizes the importance of sustainable sourcing and production. The Materials category within BREEAM specifically addresses life cycle impacts, promoting the selection of materials that minimize environmental harm.

By integrating LCA principles, BREEAM aligns itself with broader sustainability goals, encouraging construction projects worldwide to prioritize environmentally responsible practices and contribute to a more sustainable built environment.
