Key Takeaways
- Product sustainability is no longer a marketing choice. It is a measurable, verifiable, and legally enforceable standard that regulators are enforcing across the EU and beyond.
- 73% of consumers worldwide are willing to change their purchasing behaviour to reduce environmental impact, making sustainable products a genuine commercial opportunity.
- Real carbon footprint data from ISO 14040/44-compliant LCAs shows enormous variation across product categories, meaning every brand needs its own numbers, not industry averages.
- From 27 September 2026, generic environmental claims such as “environmentally friendly,” “eco-friendly,” “green,” “natural,” “biodegradable,” “climate neutral” or “sustainable” are prohibited unless based on recognised performance standards.
- Life Cycle Assessment (LCA) is the methodology that bridges intention and proof, turning sustainability from a story into a science.
What Does Product Sustainability Actually Mean?
Product sustainability is one of those phrases that gets used constantly and defined rarely. At its core, it refers to the extent to which a product can be designed, manufactured, used, and disposed of without causing lasting harm to people or planet. That covers everything from the raw materials a brand sources to the energy used on the factory floor, the weight of the packaging, and what happens after the consumer is done with the product.
For years, this definition was loose enough to accommodate almost any claim. A brand could call a shampoo “eco-friendly” because it skipped one synthetic ingredient, or market a laptop as “sustainable” because the cardboard box was recycled. That era is drawing to a close. Regulatory frameworks are converging on a single principle: if you make a sustainability claim about a product, you need evidence that would hold up to independent scrutiny.
Understanding where your product’s environmental impact actually comes from is the first step. That requires data, ideally, data generated through a structured, repeatable methodology like a Life Cycle Assessment.
Why the Regulatory Landscape Is Reshaping Everything
The pace of change in sustainability regulation has accelerated sharply. In the EU, several pending regulations are shifting sustainability from voluntary commitments toward concrete, verifiable requirements, covering environmental claims, product requirements, packaging, and chemicals.
The most immediate deadline for product brands is the EU Green Claims Directive. The EU’s new Empowering Consumers for Green Transition (EmpCo) directive will ban generic claims like “eco-friendly” or “carbon neutral” by late 2026 unless backed by recognised proof. Businesses that have been relying on vague language in their product marketing need to act now. Businesses cannot use sustainability labels unless these are based on third-party certification or established by public authorities, and companies must conduct comprehensive audits of all marketing materials to identify and remove or substantiate claims.
The trust gap driving this regulation is very real. Approximately 53% of all environmental claims in the EU are vague, misleading, or unsubstantiated, according to the EU Commission. Only 20% of consumers trust companies’ sustainability claims. Brands that can close this gap with verified data are not just avoiding legal risk, they are building a genuine competitive advantage.
On the reporting side, the CSRD landscape has shifted too. On 26 February 2026, the EU published Directive (EU) 2026/470 (the Omnibus I Directive), effectuating far-reaching changes to both the Corporate Sustainability Reporting Directive (CSRD) and the Corporate Sustainability Due Diligence Directive (CS3D). While this has narrowed the scope of mandatory reporting, the key theme for 2026 is clear: regulatory relief does not eliminate business drivers. Climate risk intensification, investor scrutiny, customer expectations, and capital access linked to credible sustainability strategies all remain firmly in place. Although fewer companies now face mandatory obligations, voluntary leadership increasingly distinguishes market leaders from laggards.
The Business Case: Consumers Are Paying Attention
Beyond compliance, the commercial logic for product sustainability is compelling. Consumers are willing to spend an average of 9.7% more for sustainably produced or sourced goods, according to PwC’s 2024 Voice of the Consumer Survey of more than 20,000 consumers across 31 countries.
Products marketed as sustainable grew 2.7x faster than those that were not. And consumers spent an estimated $230 billion on sustainably marketed products in 2025, representing 24.8% of consumer retail spending.
That said, the relationship between sustainability intent and purchasing behaviour is more nuanced than headline figures suggest. Over one-third of respondents wanted to buy a sustainable product but were hindered by factors including price, limited awareness and lack of availability, highlighting a substantial unmet demand. This means brands that make sustainable products genuinely visible and accessible, with clear, credible claims, stand to capture a significant share of consumers who are motivated but currently stuck.

What the Numbers Look Like: Real LCA Benchmarks
One of the most important things LCA does is replace vague impressions with actual data. How much CO₂ does a t-shirt really generate? What phase of a laptop’s life dominates its footprint? The answers are often surprising, and they are almost always specific.
Here are three benchmarks calculated by Devera using Monte Carlo LCA methodology, fully compliant with ISO 14040/44:
| Product | Median Carbon Footprint | Biggest Impact Phase | Grade A Threshold |
|---|---|---|---|
| T-Shirt | 3.01 kg CO₂e | Manufacturing (60.1%) | < 2.41 kg CO₂e |
| Body Cream | 2.50 kg CO₂e | Raw materials (47.7%) | < 1.99 kg CO₂e |
| Laptop | 215.10 kg CO₂e | Use phase (38.3%) | < 176.3 kg CO₂e |
These figures are not averages pulled from secondary databases. They reflect real variability modelled across product configurations and supply chains.
Notice how differently each product behaves. For a t-shirt, the dominant impact is manufacturing, which accounts for 60.1% of the total footprint. This means sustainability improvements in textile production, dyeing processes, energy sources, water use, will have a far greater effect than switching to recycled packaging. For a body cream, raw materials drive 47.7% of the impact, pointing to ingredient sourcing as the key lever. A laptop is different again: the use phase (38.3%) and raw materials (36.5%) are almost equally significant, meaning energy efficiency and design for longevity both matter enormously.
This kind of phase-level insight is what makes LCA so valuable. Without it, sustainability teams often optimise the wrong part of the product’s life cycle.
How LCA Connects Sustainability to Strategy
Life Cycle Assessment, as defined under ISO 14040 and ISO 14044, is the internationally recognised framework for evaluating the environmental impacts of a product across its entire life, from resource extraction through to end of life. It is the methodology behind Devera’s benchmarks, and it is the methodology that regulators are increasingly pointing to as the basis for credible green claims.
Running an LCA used to mean months of work and significant consulting fees. That has changed. Automated platforms can now generate ISO-compliant footprint calculations at product level, making it accessible for brands of all sizes. If you want to understand where to start, the Essential Guide for Calculating the Carbon Footprint of Products walks through the methodology in practical terms.
What a Good LCA Actually Tells You
A well-executed LCA gives you three things that matter strategically.
First, it tells you where the impact is concentrated. As the benchmark data above shows, raw materials, manufacturing, packaging, transport, and use phase contribute very differently depending on the product category. You cannot reduce what you have not measured.
Second, it gives you a defensible number. When a regulator or a retailer asks you to substantiate your sustainability claim, “we have run a Monte Carlo LCA compliant with ISO 14040/44 and our product scores X kg CO₂e” is an answer. “We use recycled packaging” is not.
Third, it enables comparison over time. Once you have a baseline, you can track whether reformulations, supplier changes, or production improvements are actually moving the needle, or not.
From Measurement to Communication: Avoiding the Greenwashing Trap
Measuring product sustainability is one thing. Communicating it without crossing into greenwashing territory is another challenge entirely. The regulatory risk here is real. The UK’s consumer protection law now enables the CMA to fine companies up to 10% of global turnover for unsubstantiated or deceptive sustainability claims.
The good news is that the same data that protects you from regulatory risk also makes your sustainability communication more compelling. Specific numbers, peer-reviewed methodology, and third-party verification are far more persuasive to sceptical consumers than adjectives. For practical guidance on staying on the right side of this line, 12 Best Ways to Avoid Greenwashing and Comply With the Green Claim Normative covers the key principles in detail.
ESG data must be consistent across sustainability reports, green claims, supply chain documentation, and packaging strategies. A centralised, product-level measurement system is what makes that consistency possible.
A Practical Roadmap for Brands in 2026
Product sustainability is not a single project with an end date. It is an ongoing process of measurement, improvement, and communication. But it does have a logical starting sequence.
- Measure first. Run an LCA on your priority products. Understand where the impact sits before you decide where to invest.
- Set a baseline and grade. Use a scoring framework to benchmark your products against sector peers. This gives you both internal targets and external context.
- Identify the highest-leverage interventions. Is it raw material sourcing? A manufacturing process? Packaging weight? The LCA will tell you.
- Substantiate your claims. Before any sustainability claim goes on a label, website, or press release, confirm it is backed by verifiable, documented evidence.
- Communicate with specificity. Replace vague language with concrete data. “2.50 kg CO₂e per unit, with raw materials accounting for 47.7% of impact” is both more accurate and more trustworthy than “eco-friendly formula.”
Frequently Asked Questions
What is product sustainability and why does it matter in 2026? Product sustainability refers to designing, producing, and selling goods in ways that minimise environmental and social harm across the full product life cycle. In 2026, it matters both because consumers are actively choosing brands that demonstrate genuine environmental responsibility, and because regulators across the EU are making unsubstantiated sustainability claims legally risky.
How is product sustainability measured scientifically? The most rigorous approach is a Life Cycle Assessment (LCA) conducted under ISO 14040 and ISO 14044 standards. LCA quantifies environmental impacts across every phase of a product’s life, from raw material extraction to end of life, expressed as a carbon footprint in kg CO₂e and often covering additional impact categories such as water use and eutrophication. You can calculate your product carbon footprint using Devera’s automated LCA platform.
What are the biggest regulatory risks for brands making sustainability claims? From September 2026, the EU’s Empowering Consumers for the Green Transition Directive prohibits generic terms like “eco-friendly,” “green,” or “sustainable” on products unless backed by recognised third-party evidence. Brands in the UK face similar exposure under the CMA’s new enforcement powers, which allow fines of up to 10% of global turnover for misleading environmental claims. Conducting an LCA before making any claim is the most effective way to manage this risk.
Which phase of a product’s life cycle has the biggest environmental impact? It varies significantly by product type, which is exactly why LCA is so valuable. For a t-shirt, manufacturing accounts for 60.1% of the total footprint. For a body cream, raw materials drive 47.7%. For a laptop, the use phase and raw materials each contribute over 35%. Without phase-level data, brands risk investing in the wrong part of the supply chain and missing their actual biggest impact.
