Both process-based and input-output life cycle assessment methods can identify similar significant environmental impacts in service industries, primarily related to energy use, building construction, and business travel, though process-based LCA struggles with assessing purchased services. This sustainability research insight is drawn from a 2006 study published in Environmental Science & Technology. Using Empirical comparative study, researchers explored how this design variable affects real-world outcomes. The key design takeaway: For service industries, prioritize understanding the environmental impacts of direct operations (energy, travel) and be mindful of the complexities in assessing indirect impacts from supply chains, potentially favouring input-output or hybrid LCA approaches for a more complete picture.

Key Findings
- 01Both LCA methods identified electricity use, building construction, business travel, heating, and business flights as significant environmental impact areas.
- 02Process-based LCA was found to be inadequate for properly assessing the environmental impacts of purchased services.
- 03Theoretical differences concerning cut-offs in purchased services, price variations, and atypical electricity production significantly influenced LCA results.
Application
Design takeaway
For service industries, prioritize understanding the environmental impacts of direct operations (energy, travel) and be mindful of the complexities in assessing indirect impacts from supply chains, potentially favouring input-output or hybrid LCA approaches for a more complete picture.
How to apply
When designing services or evaluating the environmental performance of a service business, use this research to guide the choice of LCA methodology. If purchased services are a significant component, ensure the chosen method can adequately capture their environmental burden.
Project actions
- 01When choosing an LCA method for your design project, consider the type of industry you are analyzing.
- 02Be aware of the strengths and weaknesses of different LCA approaches, especially when dealing with complex supply chains or purchased services.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Empirical comparison of two major LCA methodologies.
- +Focus on the under-researched service industry sector.
Limitations
The specific service industry chosen for your design project might have unique characteristics that affect how well these LCA methods compare. Also, data availability for both methods can be a practical challenge.
Reliability & validity
The reliability of the findings depends on the thoroughness of the LCA application by the authors and the representativeness of the case organization. Validity is supported by the empirical comparison and discussion of theoretical differences, though generalizability to all service industries may be limited.
Think critically
How might the 'price inhomogeneity' and 'industry-atypical electricity production' mentioned in the findings specifically influence the results of an input-output LCA compared to a process-based LCA in a service industry context?
Design Principles
"Select LCA methodology based on the specific scope and nature of the service industry being analyzed, paying close attention to the treatment of purchased services."
Understanding the most effective LCA methodology for service industries is crucial for accurate environmental impact assessment and the development of targeted sustainability strategies. This insight helps designers and researchers choose the right tools to identify and mitigate environmental burdens within the tertiary sector.
What This Means for Your Design
When trying to figure out how 'green' a service company is, both detailed step-by-step analysis and broader economic analysis point to similar problems like electricity use and travel. But, the detailed method isn't great at figuring out the environmental cost of services the company buys from others.
How to use in your project

Paragraph starter
This research empirically compares process-based and input-output life cycle assessment (LCA) methods in service industries, finding that while both identify key impacts like energy use and travel, process-based LCA has limitations with purchased services. This highlights the importance of selecting an appropriate LCA methodology based on the specific context of the service industry being analyzed to ensure comprehensive environmental impact assessment.
