1. Utilitarianism (In-depth Analysis)

Utilitarian ethics judges actions based on their consequences, with the goal of maximising overall happiness or well-being and minimising harm. From this perspective, greenwashing creates a profound net loss of utility for society, making it ethically indefensible.

While the deceptive company may gain short-term utility through increased sales, cost savings from avoiding genuine sustainable investment, and an enhanced brand image, these benefits are vastly outweighed by the diffuse and long-term harms inflicted on a much larger number of stakeholders.

• Consumer Harm: Consumers are misled into purchasing products under false pretences, often paying a price premium for non-existent environmental benefits. This constitutes a financial loss and a betrayal of trust, leading to cynicism and disengagement from sustainable consumption altogether.

• Competitor Harm: Companies that invest genuinely in sustainable practices suffer an unfair competitive disadvantage. Their legitimate products may be overlooked in a marketplace flooded with cheaper, deceptively marketed alternatives, stifling innovation and punishing ethical behaviour.

• Societal & Environmental Harm: Greenwashing delays critical environmental action by creating a false impression of progress. It misallocates resources away from genuine solutions and erodes public trust in environmental science, corporate reporting, and governance. The ultimate consequence is a slower response to environmental crises like climate change, which negatively impacts the well-being of current and future generations.

The utilitarian calculus is clear: the minor, short-term benefits for a single corporation are overwhelmingly outweighed by the significant, long-term harms to consumers, honest competitors, and society at large.

2. Deontology (Brief Analysis)

In contrast, deontological ethics focuses on duties, rules, and the inherent rightness or wrongness of actions, regardless of their outcomes. From this viewpoint, greenwashing is fundamentally wrong because it violates the categorical duty of honesty. It treats consumers as a mere means to an end (profit) rather than as rational beings who deserve truthful information to make autonomous choices (Brenkert & Beauchamp, 2010). This breach of the fundamental duty of non-deception makes it ethically impermissible, even if it were to somehow yield positive consequences.

The analysis shows that greenwashing is a direct and potent obstacle to SDG 12. It corrupts the information ecosystem necessary for sustainable consumption and makes it impossible to accurately measure progress toward sustainable production. For Target 12.6 to be meaningfully achieved, sustainability information must be authentic and verifiable, not a marketing tool. Eradicating greenwashing is, therefore, a prerequisite for the practical implementation and credibility of the entire goal.
