Comparative LCA Consulting Services
Are you trying to determine how one product compares with another, or how your product performs against the competition?
Are you planning to make a public environmental claim that one product is preferable to another?
When comparative results are disclosed externally, international standards require a higher level of rigor, transparency, and independent verification. That’s where expert comparative Life Cycle Assessment (LCA) consulting becomes essential.
What Is a Comparative Life Cycle Assessment?
A comparative Life Cycle Assessment evaluates the environmental impacts of two or more products, systems, or scenarios across their full life cycles, from raw material extraction and manufacturing to use and end-of-life.
When used to support public claims, comparative LCAs must comply with International Organization for Standardization standards ISO 14040 and ISO 14044, which require:
- Clearly defined functional units
- Transparent system boundaries
- High-quality, representative data
- Sensitivity and uncertainty analysis
- A mandatory third-party critical review
Without this level of rigor, comparative environmental claims can create legal, reputational, and compliance risks.
Put the Science Behind Your Environmental Claims
At LTS, we conduct extensive, ISO-compliant comparative LCAs that go beyond screening-level studies. Our work refines assumptions, strengthens datasets, and ensures that conclusions are scientifically defensible and ready for critical review.
We help you:
- Demonstrate environmental superiority with confidence
- Identify meaningful performance differences
- Avoid greenwashing risks
- Strengthen marketing and sustainability communications
- Prepare documentation for third-party critical review panels
Whether you are comparing product formulations, packaging systems, materials, manufacturing processes, or end-of-life scenarios, we provide robust analysis that stands up to scrutiny.
Our Comparative LCA Approach
1. Goal & Scope Definition
We define a clear functional unit and ensure equivalency between compared systems—an essential requirement for valid comparison.
2. Life Cycle Inventory (LCI)
We collect and validate primary data, supplement with high-quality secondary databases, and ensure transparency across supply chains.
3. Impact Assessment (LCIA)
We quantify environmental indicators such as carbon footprint, energy demand, water use, resource depletion, and other relevant impact categories.
4. Sensitivity & Uncertainty Analysis
We test assumptions and confirm that comparative conclusions are robust and not driven by modeling artifacts.
5. Critical Review Preparation
We prepare a comprehensive, ISO-aligned report suitable for independent third-party review.
When Is a Comparative LCA Required?
You may need a comparative LCA if you are:
- Making public claims that one product is “better for the environment”
- Entering eco-label or certification programs
- Responding to customer sustainability requirements
- Supporting Environmental Product Declarations (EPDs)
- Preparing for regulatory or investor scrutiny
ISO standards require that comparative assertions disclosed to the public undergo a critical review by an independent expert panel. We design your study from the outset to meet this requirement efficiently.
