A comprehensive analysis of Amazon sales data reveals that sustainability labels like “Climate Pledge Friendly” increase consumer demand by 13–14% for up to eight weeks after adoption. This sales boost is not driven by pricing or advertising, nor by improved search rankings or filter usage. Instead, consumers engage in passive search—opting for labeled products when given the choice, even if they’re not actively looking for sustainable options. Labels that highlight specific features, such as carbon neutrality or reduced harmful ingredients, are especially effective. For brands and platforms, this underscores the commercial value of clear, credible sustainability messaging.
