Life Cycle Assessment (LCA) & Environmental Product Declarations (EPD)

We deliver reliable Life Cycle Assessments (LCA) and Environmental Product Declarations (EPD) to help you meet regulatory requirements, improve product sustainability, and communicate verified environmental performance.

What is a Life Cycle Assessment?

A life cycle assessment (LCA) is a systematic and scientific methodology used to evaluate the environmental impacts associated with the entire life cycle of a product, process, or service. It is a comprehensive approach that considers all stages of the life cycle, from raw material extraction and production to distribution, use, and disposal. The goal of an LCA is to quantify and assess the environmental footprint and benefits associated with a particular system or product, providing a holistic perspective on its sustainability.

Ex: For a smartphone, the process begins with emissions produced during the extraction of raw materials, such as the metals used in the manufacturing stage. Emissions from consumed energy are also considered at this stage. The assessment will then account for emissions produced in the distribution phase (i.e., caused by the transportation of the smartphone from the producer to the consumer), the energy consumption during its use phase and the ecological footprint associated with its disposal, at the end of the smartphone’s life.

The Steps of an LCA

Step 1: Goal and scope definition, where the objectives of the assessment are established

In Phase 1 of a life cycle assessment (LCA), the goal and scope are determined, setting the direction for the entire project. Goals can vary, from identifying environmental hotspots to reducing a product's carbon footprint. This phase defines the boundaries of the assessment, whether it's a cradle-to-grave analysis covering raw material extraction to disposal or a cradle-to-gate analysis focusing on the product until shipment.

Step 2: Defining system boundaries.

Defining the system boundaries in a life cycle assessment (LCA) involves setting the limits of the analysis, determining what processes and activities will be included or excluded. This decision is crucial for accuracy and relevance, guided by the goals and objectives of the LCA. Balancing comprehensiveness with practicality is key to ensure meaningful insights into the environmental performance of the subject, whether it's a cradle-to-grave analysis covering the entire life cycle or a cradle-to-gate analysis focusing on pre-shipment stages.

Step 3: Inventory analysis – the gathering of detailed data on the inputs and outputs of material and energy flows throughout the life cycle.

This phase consists of the careful examination of resource consumption, emissions, and other relevant flows associated with raw material extraction, production, distribution, use, and disposal. The goal is to create a robust inventory of environmental inputs and outputs, providing a quantitative foundation for assessing the overall environmental impact of the product or system.

Step 4: Impact assessment – the inventory data is translated into potential environmental impacts. This includes assessing factors such as greenhouse gas emissions, resource depletion, acidification, and more.

Impact assessment in a LCA is the stage where the comprehensive inventory data, gathered in the previous phase, is translated into potential environmental impacts. This involves applying specific models and characterization factors to quantify the significance of various environmental effects associated with the material and energy flows identified during the inventory analysis.

Step 5: Result interpretation – the results are analyzed, uncertainties are considered, and recommendations for improvement are formulated.

The goal is to derive meaningful insights into the environmental performance of the analyzed system, identifying areas for improvement and formulating scientifically informed recommendations. This phase is crucial for translating the quantitative outcomes of the LCA into actionable insights.

What are the benefits of an LCA?

LCAs facilitate the identification of hotspots and areas for improvement across the entire life cycle, guiding efforts to reduce resource consumption, emissions, and overall environmental footprint. Additionally, LCAs contribute to the development of eco-friendly products and processes by offering a systematic approach to assess and optimize sustainability aspects.

Comprehensive Perspective: Engaging in a life cycle assessment (LCA) offers a thorough understanding of the environmental consequences linked to a product, process, or service, taking into account every stage of its life cycle.

Environmental Impact Reduction: LCAs identify and address environmental hotspots in a product's lifecycle, leading to targeted improvements and an overall reduction in environmental impact.

Resource Preservation: LCAs reveal opportunities for efficient and sustainable resource use by highlighting areas of inefficiency and suggesting alternatives for better resource conservation.

Savings: Cost Implementing LCA recommendations streamlines processes, promotes the use of economical materials, and results in cost savings for organizations through increased efficiency.

Risk Management: LCAs assist in identifying and evaluating potential risks throughout a product's lifecycle, enabling organizations to implement effective risk management strategies.

Stakeholder Relationships: Demonstrating commitment to sustainability and transparency through LCA practices strengthens relationships with stakeholders, fostering engagement, enhancing brand reputation, and providing a competitive edge in the market.

Supply Chain Optimization: By assessing the entire value chain, LCAs aid in optimizing supply chain processes and identifying sustainable sourcing practices.

Market Differentiation: Products with lower environmental impacts, as determined by LCAs, can be marketed as environmentally friendly, providing a competitive edge.

Sustainable Practices: Organizations can adopt sustainable practices based on LCA insights, contributing to corporate social responsibility and environmental stewardship.

Continuous Improvement: Regular LCAs support a cycle of continuous improvement, allowing organizations to track progress, implement changes, and monitor their environmental performance over time.

Environmental Product Declarations (EPDs)

Type III Environmental Product Declaration (EPD) is a third-party verified and registered document that communicates the environmental impacts of a product across its life cycle. Based on a Life Cycle Assessment (LCA), an EPD provides transparent, science-based information on environmental performance, supporting sustainable decision-making across value chains. They play an increasingly important role in sustainability and ESG consulting, as they enable companies to disclose verified environmental data in a credible and comparable way. This helps organizations respond to growing ESG disclosure requirements, sustainable procurement criteria, and customer expectations for transparency.

Such an EPD reports predetermined environmental indicators, such as Global Warming Potential (GWP), energy use, water use, acidification, eutrophication, and abiotic resource depletion to name a few.

These indicators are calculated according to a predefined set of rules, called Product Category Rules, ensuring methodological consistency and allowing fair comparison between products within the same category.  

EPDs are widely used in sectors such as construction, manufacturing, and industrial production, where environmental performance is a key selection criterion.

They support green building certifications, sustainable supply chain management, and product-level ESG reporting.

For companies, they are used to reduce greenwashing risks and strengthen credibility with clients, investors, and regulators.

FAQs - Your questions answered about LCA and EPD

How long does a Life Cycle Assessment usually take?

The duration of an LCA depends on product complexity, data availability, and system boundaries. A typical project can range from a few weeks to several months for complex products or value chains.

What is the difference between LCA and carbon footprint?

A carbon footprint looks only at greenhouse gas emissions and climate impact, while an LCA covers multiple environmental indicators such as energy use, water use, acidification, eutrophication, and resource depletion. In practice, a carbon footprint is often one part of a full LCA.

Can an LCA be updated over time?

Yes. LCAs are often updated to reflect changes in suppliers, processes, or energy mixes. Updating an existing LCA is usually faster and more cost-effective than starting from scratch

Is LCA relevant for ESG reporting and CSRD compliance?

Yes. LCA supports environmental disclosures by providing robust, traceable data on multi‑category impacts and GHG emissions across the life cycle, which can underpin ESRS E1/E2 metrics and targets. It is particularly relevant for product‑level analysis, Scope 3 (purchased goods and services), and value chain transparency under ESG and CSRD reporting frameworks, even though it is not explicitly mandated by CSRD.

When is an LCA required?

An LCA is required when companies need EPDs, want to participate in green building projects, respond to sustainable procurement criteria, or provide verified environmental data to clients, investors, or regulators. It is increasingly requested in construction, manufacturing, and industrial sectors.

Are EPDs mandatory or voluntary?

EPDs are generally voluntary, but they are increasingly required by clients, public tenders, and green building schemes. In some sectors, EPDs have become a de facto market requirement.

Can one LCA be used for multiple EPDs?

In some cases, yes. A well-structured LCA can serve as the basis for several EPDs, provided that each product variant complies with the relevant Product Category Rules.

How do EPDs support sustainable procurement?

EPDs allow buyers to compare products based on verified environmental data. This supports transparent supplier selection and aligns procurement decisions with sustainability and ESG objectives.

Does an LCA or EPD help reduce greenwashing risks?

Yes. Both LCA and EPD rely on standardized methodologies and verifiable data. Type III EPD's are third party verified document and businesses usually prefer and usually have in mind the type III EPD when somebody mentions EPD's. This reduces the risk of unsubstantiated environmental claims and strengthens credibility with stakeholders.

When should a company choose EPD development instead of a standalone LCA?

EPDs are recommended when external communication, tenders, client, compliance and public procurement requirements demand standardized product disclosures. A standalone LCA is often sufficient for internal analysis and strategy development. Verified EPD's are published publicly in a choice of their program operators such as Internation EPD system, EPD hub, IBU, BRE.
