A three-item scale measuring a consumer's belief in the environmental effectiveness of green products — specifically whether purchasing and using such products genuinely contributes to environmental protection and pollution reduction. One item is reverse-scored. Developed as part of a broader study on consumer ambivalence toward sustainable consumption, the scale focuses on the instrumental environmental dimension of green product attitudes rather than aesthetic, ethical, or social identity aspects.
Likert (format not specified; likely 7-point agree/disagree)
