If you're reading this, chances are you're embarking on a green transition of sorts. It can be yours, or others', in your company or outside of it, and it can be a department, a product, a company, or pretty much anything! In today's world, sustainability has become an important focus for businesses, and understanding the environmental impact of their products and processes is crucial.

And if you're reading this, you're interested in seeing how Life Cycle Assessment (LCA) fits in your context. LCA is a valuable tool that can provide valuable insights and guide companies in their efforts to become more sustainable. But how exactly does it do that?

What is Life Cycle Assessment?

Before we dive into the ways LCA can help companies go green, let's first understand what Life Cycle Assessment is all about. LCA is a systematic analysis method that evaluates the environmental impact of a product or process throughout its entire life cycle - from raw material extraction to disposal.

LCA accounts for all your interactions (with the environment, with other companies, or internal). Those interactions can have a direct impact (emissions that cause an environmental impact themselves, e.g. CO2 emissions), or indirect (you purchase aluminium, that takes a lot of energy to produce, which in turn emits different chemicals for its production.

Because LCA accounts for all of them together, it is capable of giving you a clear picture of which interactions (materials, energy use, waste management, processes, etc) are driving the biggest environmental impact. By quantifying the environmental impact, LCA enables companies to identify areas for improvement and make informed decisions to minimize their ecological footprint.

The Benefits of Life Cycle Assessment

Implementing Life Cycle Assessment can bring numerous benefits to companies aspiring to go green. Let's explore five key ways LCA can help companies achieve their sustainability goals:

1. Identifying Hotspots

Through Life Cycle Assessment, companies gain a holistic view of their products or processes, allowing them to identify environmental hotspots where the most significant impacts occur. These hotspots can range from high carbon emissions during production to inefficient resource use or excessive waste generation.

By understanding these hotspots, companies can prioritize their efforts to address the critical areas and implement measures to reduce the associated environmental impacts effectively.

2. Setting Sustainability Targets

Once companies are aware of the hotspots discovered through LCA, they can set sustainability targets accordingly. These targets provide clear guidelines and goals for reducing environmental impact, encouraging companies to adopt greener practices.

For example, a company might aim to reduce its carbon emissions by a certain percentage within a specific timeframe or minimize water consumption during a product's manufacturing process. LCA helps quantify the baseline and measure progress towards these targets, allowing companies to track their sustainability performance accurately.

3. Designing More Environmentally Friendly Products

Life Cycle Assessment can act as a powerful tool for product design and development. By understanding the environmental impact of different materials, manufacturing processes, and product alternatives, companies can make informed decisions that result in more sustainable products.

LCA enables a holistic assessment of the entire life cycle of a product, considering factors such as raw material sourcing, manufacturing, usage, and disposal. By optimizing each stage, companies can develop products that have a lesser impact on the environment without compromising on quality or performance.

4. Supplier Collaboration

LCA not only helps companies assess their own environmental impact but also facilitates communication and collaboration with suppliers. By sharing LCA data and working together, companies and their suppliers can identify opportunities for improvement. And by doing so in a clear and specific way, both sides share a clear language about initiatives and impacts.

For example, suppose a company discovers that a significant portion of its carbon emissions is stemming from the transportation of raw materials by its suppliers. In that case, it can collaborate with those suppliers to find more sustainable transportation options, optimize routes, or explore local sourcing alternatives. Through such collaborative efforts, companies can work towards a greener supply chain and ensure that sustainability is considered at every stage of production.

5. Enhancing Transparency and Communication

The value chain goes both ways. Communication and collaboration with customers also benefits from clearer understanding of environmental impacts. Life Cycle Assessment provides a scientific basis to evaluate and communicate a company's environmental performance. By quantifying the environmental impacts, companies can enhance transparency and credibility by sharing the LCA results with stakeholders, such as customers, investors, and regulatory bodies.

Having solid LCA data allows companies to provide evidence of their commitment to sustainable practices and showcase their progress towards achieving specific environmental goals. Transparency and effective communication can also help build trust and attract environmentally conscious customers.


Life Cycle Assessment is a powerful tool that can assist companies in their journey towards sustainability. By understanding and quantifying the environmental impact of their products and processes, companies can identify areas for improvement, set measurable targets, design greener products, collaborate with suppliers, and enhance transparency.

Ultimately, implementing Life Cycle Assessment can help companies go green by reducing their ecological footprint, operating more efficiently, and contributing to a more sustainable future.
