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.
