Life Cycle Assessment services for product-level transparency

Your organisational carbon footprint tells you what your business emits. A Life Cycle Assessment tells you what your products cost the planet, from raw material extraction to end of life. That is the data your clients, regulators, and procurement teams are increasingly asking for.

At Green Earth, we provide LCAs, product carbon footprints (PCFs), and third-party verified Environmental Product Declarations (EPDs), giving you the product-level environmental data you need to compete, comply, and communicate with confidence.

Why product-level data matters now

Environmental disclosure is now a market requirement

people on a pedestrian crossing

Supply chain emissions account for 80–90% of most companies' environmental footprint. Yet a PwC study found that only 69% of companies had conducted LCAs on fewer than 25% of their product lines. The gap between expectation and action is wide, and closing fast.

96% of customers are now interested in the sustainability of the products they buy. Clients are embedding environmental data into procurement decisions. EU regulators are tightening product-level disclosure obligations. And B2B buyers are requesting verified impact data at SKU level. Businesses that can't accurately measure and prove their environmental footprint face a growing risk of compliance failures, lost market share, and reputational damage.

What we offer

3 types of product environmental
reporting, 1 expert team

Life Cycle Assessment (LCA)

An ISO-compliant evaluation of a product's environmental impact across its entire life cycle: from raw material extraction through manufacturing, distribution, use, and end-of-life disposal. An LCA gives you the complete, science-based picture that underpins credible sustainability claims, regulatory submissions, and product development decisions.

Product Carbon Footprint (PCF)

A focused assessment of the greenhouse gas emissions associated with a specific product or SKU across its life cycle. PCFs are increasingly requested by enterprise buyers, required under sector-specific regulations, and used to support Environmental Product Declarations and eco-labelling programmes.

 

Environmental Product Declaration (EPD)

A third-party verified, standardised document that communicates a product's environmental performance in a transparent, comparable format. EPDs are required for materials in many procurement frameworks and increasingly used across manufacturing and consumer goods to substantiate sustainability claims.

Is this for your business?

You need product-level environmental data if...

You are a manufacturer whose B2B clients are asking for emissions data at product or component level.

You are supplying into construction, infrastructure, or public procurement frameworks that require EPDs.

You need to substantiate eco-labelling claims 
or respond to green marketing regulations.

You are preparing for EU product environmental footprint requirements
 or sector-specific regulatory disclosure, like CPR, CBAM, 
and ESPR.

Your Scope 3 reporting obligations require you 
to provide upstream or downstream product emissions data to customers in your supply chain.

You want to identify where in your product life cycle
the biggest reduction opportunities lie.

A clear process from data collection to verified declaration

We work with you from the first scoping to your verified declaration. Every step is structured, transparent, and built around your specific products and reporting needs.

1
Scoping

We define the product, system boundary, and functional unit, establishing exactly what is measured and to which standard.

2
Data collection

We work with your team to gather the activity data, supplier information,
and process documentation needed for an accurate life cycle inventory.

3
Impact assessment

We apply recognised LCA methodologies to quantify environmental impacts,
including CO₂ emissions, energy use, water consumption.

4
Verification and declaration

Your assessment undergoes independent third-party verification,
producing a credible, comparable EPD you can share.

Why choose Green Earth

Product expertise rooted 
in organisational depth

Most LCA providers stop at the assessment. Green Earth connects product-level environmental data to your broader sustainability strategy — carbon footprint measurement, CSRD reporting, carbon credit compensation, and EPD delivery — from a single expert team.

Our partnership with One Click LCA provides the data infrastructure that makes LCAs faster, more accurate, and more cost-effective. Rather than starting from scratch, we build on the emissions data and reporting processes your business already has in place.

FAQ

What is the difference between an LCA and a product carbon footprint?

A product carbon footprint (PCF) focuses specifically on greenhouse gas emissions across a product's life cycle, expressed in CO2​ equivalent. A full LCA covers a broader range of environmental impact categories, including water use, land use, particulate matter, and resource depletion, depending on the scope defined at the start of the project. Which one you need depends on your regulatory requirements, client expectations, and intended use of the results. We help you determine the right scope before committing to a methodology.

What is an EPD and when do I need one?

An Environmental Product Declaration is a standardised, third-party-verified document that communicates a product's environmental performance. EPDs are required for construction materials in many public procurement frameworks across Europe, referenced by green building certification schemes such as BREEAM and LEED, and increasingly requested by large buyers in manufacturing and consumer goods. If your clients are asking for verified environmental performance data or if you are selling into regulated procurement channels, an EPD is likely what you need.

How long does an LCA take?

Timeline depends on the complexity of the product, the availability of supply chain data, and the number of impact categories included. A focused product carbon footprint for a product with a relatively simple supply chain can typically be completed in four to eight weeks. A full cradle-to-grave LCA with EPD verification takes longer. We scope timelines clearly at the start of each engagement.

Can you connect an LCA to our existing carbon footprint data?

Yes. Our CO2 Expert tool is designed for organisational carbon accounting, and it acts as a central hub for your product-level data. We integrate your verified LCAs into the tool to create custom, product-specific emission factors. This ensures that your corporate Scope 3 reporting and product-level sustainability goals can remain aligned.
