01

Key Findings

  • 01Subjective norms, perceived behavioral control, and behavioral beliefs significantly shape consumer expectations towards green brands.
  • 02Perceived greenwashing leads to belief disconfirmation, increased consumer confusion, reduced brand trust, and weakened brand loyalty.
02

Application

Design takeaway

Ensure all environmental claims are substantiated with credible evidence and integrated into the core design and production processes, rather than being used as a superficial marketing tactic.

How to apply

Before launching any product or campaign with environmental claims, conduct thorough consumer research to validate the claims and ensure they align with actual product attributes and consumer understanding.

Project actions

  • 01Clearly define what constitutes 'greenwashing' in your specific design context.
  • 02Consider how your design choices can either support or undermine genuine sustainability claims.

Method & Evidence

AimHow does perceived greenwashing influence consumer expectations, lead to belief disconfirmation and confusion, and subsequently impact brand trust and loyalty?
MethodQuantitative survey research and structural equation modeling.
ProcedureA survey was administered to consumers to gather data on their perceptions of green brands, expectations, experiences with environmental claims, confusion, trust, and loyalty. The collected data were then analyzed using structural equation modeling to test a theoretical model linking these variables.
Sample375 participants
ContextConsumer behavior in the context of sustainable marketing and branding.

Variables

Strengths & Limitations

Strengths

  • +Integration of multiple theoretical frameworks (Theory of Planned Behavior, Expectation Confirmation Theory, Consumer–Brand Relationship Theory).
  • +Empirical testing of a comprehensive model linking cognitive and relational mechanisms.

Limitations

The study's findings are based on self-reported data, which can be subject to biases. The specific context of Lebanon might influence results.

Reliability & validity

The study employed structural equation modeling, a robust statistical technique for assessing complex relationships, which contributes to the validity of the findings. Reliability would be assessed through internal consistency measures of the survey scales.

Think critically

To what extent do regulatory frameworks influence the prevalence and impact of greenwashing, and how can designers advocate for stronger standards?

Design Principles

"Authenticity in Sustainability: Design and communicate environmental benefits truthfully and transparently to build enduring consumer trust."

For designers and businesses aiming for genuine sustainability, understanding the negative impact of greenwashing is crucial. It highlights that authentic environmental responsibility is not just an ethical imperative but a strategic necessity for building lasting consumer relationships and achieving long-term market success.

06

What This Means for Your Design

If a company pretends to be eco-friendly but isn't, customers get confused, stop trusting the company, and won't buy from them anymore.

How to use in your project

  • 1.Use this research to justify the importance of authentic sustainability in your design process and to explain the potential negative consequences of greenwashing in your analysis.

Paragraph starter

This study by Daou et al. (2025) reveals that greenwashing significantly undermines consumer trust and loyalty by creating expectation disconfirmation and confusion. This highlights the critical need for designers to prioritize authentic sustainability in their projects, as deceptive practices can lead to negative brand perception and hinder the adoption of genuinely eco-conscious products, directly impacting the success of sustainable design initiatives.
