What is a Life Cycle Assessment? Explaining LCAs, the business benefits, and how to get started

Life Cycle Assessments (LCAs) are rapidly becoming a core requirement for large businesses navigating increasing regulatory pressure, rising costs, and growing expectations on ESG reporting transparency. Yet many organisations still struggle to understand what LCAs actually involve, and more importantly, how they deliver measurable business value.

As businesses face increasing pressure to improve sustainability performance and demonstrate transparency, Life Cycle Assessments (LCAs) are becoming an essential tool for understanding environmental impact at every stage of a product’s lifecycle.

From reducing costs and improving efficiency to supporting ESG reporting and circular economy strategies, LCAs provide the data and insight organisations need to make more informed, future-focused decisions.

In this blog, we explore what LCAs are, why they matter, and how businesses can use them to turn sustainability goals into measurable action.

What is a Life Cycle Assessment (LCA)?

Definition

A Life Cycle Assessment (LCA) is a scientific method used to analyse the environmental impacts associated with all stages of a product’s life. This is everything from the extraction of raw materials and manufacturing processes to transportation, usage, and end-of-life treatment.

The importance of LCAs

Unlike traditional reporting methods, which often focus on a single stage such as production or disposal, LCAs provide a holistic, end-to-end view. This helps businesses identify where the greatest environmental impacts occur, often highlighting unexpected areas within supply chains or product design.

LCAs allow organisations to quantify key metrics such as carbon emissions, water usage, and resource consumption, while supporting better decision-making across procurement, design, and operations.

This level of insight is critical because environmental impact is rarely isolated to one place. It is distributed across complex systems, and without a lifecycle approach, businesses risk making decisions that shift impact rather than reduce it.

EEA data shows that household consumption alone accounts for a large proportion of total environmental pressures, reinforcing why lifecycle-based approaches are essential to fully capture upstream and downstream impacts (European Environment Agency, 2025).

Why LCAs matter for large businesses

For large organisations, LCAs are no longer a “nice to have.” They are becoming a fundamental part of how businesses manage risk, demonstrate compliance, and create value.

Regulatory compliance and reporting pressures

One of the biggest drivers is regulation. Policies like extended producer responsibility are enforcing stricter requirements and placing increasing accountability on businesses for the full lifecycle of their products and packaging. This means organisations must not only manage waste but also understand and report on the materials they place on the market.

Growing stakeholder expectations

At the same time, stakeholders are demanding greater transparency. Investors, customers, and regulators are increasingly scrutinising sustainability claims, and without robust, data-backed evidence, those claims are difficult to defend. LCAs provide that evidence, enabling businesses to move from high-level commitments to measurable, verifiable performance.

The financial impact of inefficient resource use

There is also a growing financial burden. The Circularity Gap Report 2026 highlights that €25.4 trillion in economic value is lost each year due to inefficient resource use and linear economic practices. For businesses, this translates into wasted materials, inefficient processes, and missed opportunities for cost savings.

In this context, LCAs are not just about sustainability. They are about improving operational efficiency and protecting long-term profitability.

How LCAs support circular economy strategies

A large proportion of a product’s environmental impact is determined long before it reaches the market. Research suggests that over 80% of this impact is influenced at the design stage, making early decision-making critical for businesses looking to reduce their environmental footprint (European Commission).

Life Cycle Assessments play a key role here by providing end-to-end visibility across the product lifecycle. This helps businesses make more informed design choices, reducing environmental impact before it becomes embedded in materials, products, and supply chains.

Supporting the shift from linear to circular models

This is particularly important as businesses transition from linear to circular models. Rather than focusing only on production and disposal, organisations must consider how resources are used, retained, and recovered over time. LCAs support this shift by identifying where value is lost across the lifecycle and highlighting opportunities to improve efficiency.

Identifying opportunities for material efficiency

The scale of the challenge is clear. The Circularity Gap Report 2026 shows that resource use has tripled since 1970, with more than half of global greenhouse gas emissions linked to material extraction and processing. At the same time, most materials still come from virgin sources.

By identifying these impacts, LCAs enable targeted action, from redesigning products and reducing material use to improving durability and increasing recycled content. The result is not only reduced environmental impact, but also improved efficiency and long-term value.

The business case for LCAs, cost, risk, and value

For large businesses, the value of LCAs lies in their ability to connect environmental performance with commercial outcomes.

Risk reduction

From a risk perspective, LCAs help businesses identify areas of exposure. This includes regulatory risks with reporting requirements, as well as operational risks such as reliance on high-impact or volatile materials. By understanding these risks early, businesses can take proactive steps to mitigate them.

Cost optimisation

Cost optimisation is another key benefit. The Circularity Gap Report 2026 highlights that €904 billion is lost annually through processing inefficiencies alone. These inefficiencies often stem from wasted materials, energy losses, and suboptimal processes. LCAs make these inefficiencies visible, allowing businesses to address them directly.

Innovation and competitive advantage

Beyond risk and cost, LCAs also support innovation. By understanding the environmental impact of products in detail, businesses can identify opportunities to redesign products, improve performance, and differentiate themselves in the market. This is particularly important as customers increasingly prioritise sustainability in their purchasing decisions.

Future readiness

There is also a strong link to future readiness. As regulatory frameworks evolve, including potential requirements for product-level disclosures and digital product passports, businesses that already have robust lifecycle data will be significantly better positioned to adapt.

How Life Cycle Assessments work in practice

While LCAs are highly detailed, the process itself follows a structured framework that ensures consistency and comparability.

1)     Goal and scope definition

The first stage is defining the goal and scope of the assessment. This involves determining what is being assessed, why the assessment is being carried out, and which parts of the lifecycle will be included. For large organisations, this stage is critical because it sets the foundation for all subsequent analysis.

2) Life cycle inventory (LCI)

The second stage is the life cycle inventory. This involves collecting detailed data on inputs and outputs, including materials, energy use, emissions, and waste. For complex supply chains, this can be one of the most challenging aspects of the process.

3) Impact assessment (LCIA)

The third stage is impact assessment. Here, the collected data is translated into environmental impacts, such as carbon emissions, water usage, and resource depletion. This allows businesses to quantify the environmental footprint of their products in a meaningful way.

4) Interpretation

The final stage is interpretation. This is where insights are generated, and decisions are made. The goal is not just to understand the data but to use it to drive improvements across the business.

Common challenges with LCAs, and how to overcome them

Despite their value, LCAs can be difficult to implement without the right approach.

Data complexity

One of the most common challenges is data complexity. Large organisations often operate across multiple systems, regions, and suppliers, making it difficult to gather consistent, high-quality data. This can lead to gaps or inconsistencies that reduce the accuracy of the assessment.

Resource intensity

Another challenge is resource intensity. LCAs require time, expertise, and coordination across different parts of the business. Without dedicated resources, it can be difficult to maintain momentum and deliver meaningful outcomes.

Internal alignment

There is also the challenge of internal alignment. Sustainability, procurement, and product teams often have different priorities and operate in silos. Without alignment, it can be difficult to translate LCA insights into action.

These challenges can be addressed through a combination of technology, standardisation, and expert support. By working with specialists and integrating LCA processes into broader business systems, organisations can streamline delivery and improve outcomes.
