Strengths & Limitations

Strengths

  • +Provides a comprehensive overview of CLCA methodologies for the energy sector.
  • +Highlights the critical role of economic modelling in assessing indirect environmental impacts.

Limitations

Access to sophisticated economic and environmental modelling software can be a significant limitation for many design projects.

Reliability & validity

The reliability and validity of CLCA studies depend heavily on the quality and availability of data, as well as the assumptions made within the chosen economic and environmental models.

Think critically

How might the choice of economic model (e.g., equilibrium vs. input-output) influence the perceived environmental benefits or drawbacks of a particular energy technology?

05

Design Principles

"Assess the full system-wide environmental consequences of design choices, not just direct impacts."

Designers and engineers must consider the broader system-level effects of their choices. CLCA provides a robust framework to identify and quantify these indirect environmental consequences, enabling more informed decisions that minimize overall ecological impact beyond immediate product boundaries.

What This Means for Your Design

This research shows that when we look at the environmental impact of energy, we need to think about how it affects everything else, not just the energy itself. Different computer tools can help us do this, with some being more common and easier to use than others.

How to use in your project

  • 1.Use the principles of CLCA to justify the scope and boundaries of your environmental impact assessment in your design project.
