Ecolabeling

Making environmental impact visible

When discussing sustainability, understanding impact is only the first step. Life Cycle Assessment helps to make environmental impact visible, but translating that insight into everyday decisions remains a challenge. For consumers, this challenge appears at the point of purchase. For producers, it takes the form of deciding where and how to reduce impact. Ecolabelling is an attempt to bridge that gap.

From analysis to choice

The environmental impact of food products is embedded in supply chains, production systems, and resource use across the full life cycle. Ecolabels bring this information to the point of decision. By expressing environmental performance through a score, grade, and/ or visual indicator, they allow consumers to compare products quickly, without needing to interpret detailed data. At the same time, they maintain a link to the underlying analysis; connecting everyday choices to system-level impacts.

A growing number of initiatives are working in this space, with examples being platforms such as Mondra, How Good, Inoqo and CarbonCloud. Some target decision-making by producers. Others place stronger emphasis on translating environmental results into scores or labels that can be used in decision-making by consumers.

These differences are not only about presentation—they reflect deeper methodological choices. Some approaches focus on a single indicator (e.g. climate change), while others include multiple impact categories. Some rely largely on secondary datasets, while others integrate primary supply chain data. These choices directly influence the quality of the outcomes that are communicated and the potential use-cases.

Why ecolabelling can be a game changer

Ecolabelling has the potential to influence both sides of the market. For consumers, it reduces the effort required to make more sustainable purchasing decisions. Instead of relying on assumptions, it provides a structured and comparable basis for decision-making. This is particularly important because environmental impact is not directly visible and often difficult to interpret. For producers, ecolabelling creates a direct incentive to improve performance. When environmental impact becomes visible and comparable, it becomes part of how products compete. Improvements in sourcing, production, and design can translate into a better score and a stronger market position.

In this way, ecolabelling creates a feedback loop: measurement informs decisions, and decisions drive improvement. By applying life-cycle-assessment-based schemes and independent verification, such labels help consumers identify products with lower environmental impact and support more informed choices.

A growing landscape, but not yet aligned

The rapid development of ecolabelling initiatives reflects both progress and fragmentation. This process is necesary and useful, but at some point the focus needs to shift to harmonization and alignment. Different methodologies, data sources, and modelling choices can lead to different results for the same product. As a result, two labels may provide different scores for what appears to be the same product. At the same time, communication formats vary widely: some use letter grades, others numeric scores or visual indicators. This diversity reflects innovation—but it also creates confusion and limits comparability. Harmonization is therefore not a technical detail, but a prerequisite for scaling ecolabelling.

What needs to be aligned

For ecolabelling to deliver on its promise, alignment is required across several key elements:

1. The LCA method
The underlying methodology must be consistent, including choices on system boundaries, allocation, emission models, and impact assessment.

2. Primary data requirements
A minimum level of primary (company-specific) data must be defined, focusing on the most relevant impact hotspots and tailored to product categories.

3. The secondary database
The use of a common background database is essential to ensure comparability, particularly for energy use, transport, and production of ingredients.

4. The ecolabelling method
This includes how LCA results are translated into a score or label, and whether additional indicators are included.

5. Verification of compliance
Verification procedures must ensure that methods and data are applied correctly, supporting trust in the results.

6. Design of the label
The label must be clear, recognizable, and effective in influencing behaviour, while remaining consistent across products and markets.

Challenges in practice

Even with a harmonized framework in place, several challenges remain in making ecolabelling effective in practice.

• Capturing supply chain reality
  Environmental impact depends on specific practices, locations, and supply chains. Even with clear rules, translating this variability into accurate and up-to-date product data remains a challenge. In particular, ensuring traceability of raw materials and reflecting differences between producers requires continuous data improvement.

• Maintaining (and even improving) data quality over time
  Ecolabelling is not a one-time exercise. Data, production methods, and supply chains evolve. Keeping databases current and ensuring consistent (and improved) updates across thousands of products requires ongoing effort and governance.

• Balancing robustness and feasibility
  High methodological standards often imply significant data collection efforts. For companies, particularly SMEs, this can create barriers to participation. A balance is needed between scientific robustness and practical feasibility.

• Ensuring meaningful differentiation
  For ecolabels to drive change, they need to clearly distinguish between better and worse-performing products. If too many products cluster in the same category, the incentive to improve diminishes.

• Translating scores into behaviour
  Even well-designed labels do not automatically lead to different purchasing decisions. Consumer understanding, trust, and context all influence how labels are used in practice.

• Demonstrating real-world impact
  Ultimately, ecolabelling is only successful if it leads to measurable environmental improvement. This requires monitoring whether labels actually influence both consumption patterns and production practices; something that remains difficult to quantify.

This highlights that ecolabelling is not only about getting the method right, but about making it work in practice.

Making complexity actionable

Ecolabelling does not remove the complexity of sustainability, but it makes it actionable. By connecting environmental data to real-world decisions, it enables change where it matters: at the point of choice and within the systems that shape products. Its effectiveness depends on both the robustness of the underlying methodology and the clarity of its communication. And when that connection works, ecolabelling turns insight into action.
