Evidence: Strong effect

Current Life Cycle Assessment (LCA) standards and practices are not adequately equipped to accurately evaluate the environmental impacts of emerging decarbonisation strategies like carbon capture and circular economy models. This sustainability research insight is drawn from a 2023 study published in The International Journal of Life Cycle Assessment. Using Mixed-methods approach combining standards assessment, expert consultation (workshop), and case study analysis., researchers explored how this design variable affects real-world outcomes. The key design takeaway: When evaluating the environmental performance of products and systems, particularly those involving carbon capture or circularity, ensure the Life Cycle Assessment (LCA) methodology is robust, transparent, and accounts for temporal, regional, and data quality aspects.

Life Cycle Assessment Standards Need Updates for Circular Economy and Carbon Capture

The International Journal of Life Cycle Assessment · 2023

Key Findings

01Handling of waste, including CO2, and circular practices in LCA varies significantly across sectors.
02Temporal aggregation in LCA often neglects emissions over the duration of a process, reducing resolution.
03Regionalization in LCA is hampered by characterization factors that are too broad for specific local scales.
04Uncertainty and sensitivity analyses, crucial for new technologies, are often neglected or incompletely performed.

Application

Design takeaway

How to apply

When conducting or reviewing LCAs for projects involving carbon capture or circular economy principles, pay close attention to how temporal and regional factors are handled, and ensure thorough uncertainty and sensitivity analyses are performed.

Project actions

01When choosing an LCA method for your design project, consider if it's appropriate for novel or complex systems.
02If your project involves carbon capture or circular economy elements, explicitly address the limitations of standard LCA approaches and propose how to mitigate them.

Method & Evidence

AimTo critically assess the suitability of current ISO life cycle assessment standards and practices for the challenges of decarbonisation through the use of carbon capture and the circular economy.

MethodMixed-methods approach combining standards assessment, expert consultation (workshop), and case study analysis.

ProcedureThe research involved evaluating existing LCA standards, gathering insights from LCA and industry experts in a workshop, and applying identified solutions to real-world industrial decarbonisation projects through case studies. Issues were categorized into guidelines/standards, temporal/regional aspects, and data quality.

ContextEnvironmental impact assessment, industrial decarbonisation, circular economy, carbon capture technologies.

Variables

IVLife Cycle Assessment methodology (standard vs. proposed improvements for carbon capture/circularity).

DVAccuracy and comparability of environmental impact assessment results.

CVSpecific product/system being assessed, scope of LCA (e.g., cradle-to-grave).

Strengths & Limitations

Strengths

+Addresses a timely and critical issue in sustainability assessment.
+Combines theoretical analysis with practical case studies and expert input.

Limitations

The complexity of conducting a fully granular temporal and regional LCA can be a significant practical limitation for a design project due to data availability and computational resources.

Reliability & validity

Reliability could be improved by having multiple experts conduct similar assessments. Validity is enhanced by the triangulation of methods (standards review, expert workshop, case studies).

Think critically

How might the inconsistencies in LCA methodologies for carbon capture and circular systems lead to a 'greenwashing' effect, where technologies appear more environmentally friendly than they truly are?

Design Principles

"Environmental impact assessments for innovative sustainable systems must be granular, transparent, and consistently applied."

As industries transition towards sustainability, robust and consistent assessment tools are crucial. Inconsistencies in LCA methodologies for novel processes can lead to misinformed decisions, hindering effective environmental progress and potentially misrepresenting the true impact of green technologies.

What This Means for Your Design

The way we measure the environmental impact of new green technologies, like capturing carbon or reusing materials, isn't good enough yet. The rules for measuring are different everywhere, don't always look at the whole time a process takes, and aren't specific enough for local areas. This means we might not fully understand how good or bad these new technologies really are for the planet.

How to use in your project

1.Reference this research when discussing the methodology for your environmental impact assessment, especially if your design incorporates elements of carbon capture or circularity.
2.Use the identified shortcomings as a basis for justifying your chosen LCA approach or for proposing improvements to standard methods within your design project.
