Greenwashing is marketing that creates a more environmentally friendly corporate image than actual practices, products or impacts justify. It is an HL-only concept in HL.b Environmental economics, specifically syllabus understanding HL.b.5.
How Greenwashing Works
Greenwashing creates a gap between an organization's environmental claims and its actual performance. A business may emphasize one minor improvement while hiding larger impacts, use vague terms without evidence, or advertise future commitments instead of reducing present harm.
It contributes to market failure by denying consumers accurate information, potentially rewarding misleading firms over genuinely sustainable competitors.
| Greenwashing method | How it misleads consumers |
|---|---|
| Vague language | Terms such as “green” or “eco-friendly” lack measurable criteria. |
| Selective disclosure | One positive feature is promoted while larger environmental costs are omitted. |
| Unsupported claims | Benefits are stated without reliable data or independent certification. |
| Distant targets | Future promises distract from continued present-day pollution. |
A named example is the Volkswagen Dieselgate scandal. Volkswagen marketed certain diesel vehicles as environmentally cleaner, but software detected emissions testing and altered engine performance. Under normal driving conditions, the vehicles emitted substantially more nitrogen oxides than official tests suggested.
Greenwashing also reflects conflicting perspectives. Companies may use environmental language to protect sales and reputation, while consumers and environmental organizations demand transparency. It can worsen environmental injustice if pollution continues to affect vulnerable communities while companies appear responsible.
A common misconception is that every weak environmental claim is automatically greenwashing. The essential feature is that communication creates a misleading environmental impression through falsehood, exaggeration or omission.
Exam Technique
For an ESS HL response, define greenwashing precisely, explain how it distorts consumer decision-making, and use a named example. For evaluate or discuss, consider commercial incentives and the effectiveness of regulation, standardized labels, independent certification and corporate disclosure, then reach a supported conclusion.
