Short answer

Designers should conduct thorough life cycle assessments that include user modal shift analysis to accurately gauge the environmental impact of their solutions, rather than relying solely on operational efficiency.

The introduction of shared e-mopeds and e-bikes can paradoxically increase greenhouse gas emissions due to user modal shifts, challenging the assumption of inherent sustainability. This resource management research insight is drawn from a 2022 study published in Sustainability. Using Life cycle assessment (lca) combined with self-reported modal change data., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should conduct thorough life cycle assessments that include user modal shift analysis to accurately gauge the environmental impact of their solutions, rather than relying solely on operational efficiency.

Key Findings

  • 01Shared e-mopeds and e-bicycles led to an increase in greenhouse gas (GHG) emissions due to modal shifts.
  • 02Shared bicycles and personal electric scooters resulted in a decrease in GHG emissions.
  • 03Most micromobility modes, except personal e-scooters, increased particulate matter emissions but reduced in-city emissions and NOx.
  • 04New micromobility services are not inherently the best environmental solution without improved eco-design and strategic integration into transport policy.

Application

Design takeaway

Designers should conduct thorough life cycle assessments that include user modal shift analysis to accurately gauge the environmental impact of their solutions, rather than relying solely on operational efficiency.

How to apply

When designing or advocating for new mobility solutions, integrate LCA tools that account for user behaviour and modal shifts. Consider the broader urban transport ecosystem.

Project actions

  • 01When researching a product's environmental impact, think about the whole journey, not just how it's used.
  • 02Consider how your design might change people's habits and what the knock-on effects could be.

Method & Evidence

AimTo assess the environmental performance of shared e-bikes, e-scooters, and e-mopeds in Barcelona, considering their impact on user modal choice and overall greenhouse gas emissions.

Strengths & Limitations

Strengths

  • +Combines rigorous LCA methodology with real-world user behaviour data.
  • +Addresses a critical and timely topic in urban sustainability.

Limitations

Self-reported data can be inaccurate. The findings might not apply to all cities or all types of micromobility.

Reliability & validity

The use of LCA provides a standardized and robust method for environmental impact assessment. However, the reliance on self-reported modal change introduces potential validity issues due to user recall bias.

Think critically

If micromobility isn't always the most sustainable option, what design interventions or policy strategies could ensure it genuinely contributes to environmental goals?

05

Design Principles

"Environmental impact is a function of a product's entire life cycle, including user behaviour and modal substitution, not just its operational phase."

Designers and policymakers must look beyond the operational phase of micromobility solutions. A comprehensive life cycle assessment, considering user behaviour and modal substitution, is crucial for truly sustainable urban transport design.

06

What This Means for Your Design

Just because something is electric doesn't automatically make it good for the environment. How people use these electric bikes and scooters can actually make pollution worse in some cases.

How to use in your project

  • 1.Use this research to justify a deeper investigation into the life cycle impacts of your design, especially concerning user behaviour and modal shifts.

Paragraph starter

This study highlights that the environmental benefits of micromobility are complex and depend heavily on user modal shift. For instance, the introduction of shared e-mopeds and e-bikes in Barcelona led to increased greenhouse gas emissions because users switched from more sustainable transport options. This underscores the need to consider the entire life cycle and user behaviour when evaluating the sustainability of new transport solutions.
