This study initially conducted a systematic literature review to examine gender differences in environmental orientation (EO) using the New Ecological Paradigm (NEP) scale. Following PRISMA guidelines, 38 studies were selected from a total of 168, providing a comprehensive overview of the existing research on the topic. Based on the insights gained from the review, a large sample survey was then conducted to explore further the differences in EO between male and female consumers. The results were compared with previous studies employing similar methodologies. The central research question is: Does gender identity influence EO as measured by the New Ecological Paradigm (NEP) scale? The NEP scale is a well-established instrument for assessing environmental attitudes. The significance of this topic lies in the potential impact of differing attitudes among gender groups on the effectiveness of communication and comprehension. Understanding these differences is crucial for developing strategies for sustainable development through targeted and effective messaging. Our findings indicate that women exhibit a higher NEP orientation, suggesting they are more aware of environmental concerns than men. The systematic review also confirmed this trend, with the majority of studies reporting higher environmental awareness among women. Additionally, women demonstrate greater awareness of related problems and a higher willingness to change their behavior to reduce their environmental impact. In contrast, men’s attitudes are more varied, reflecting a broader diversity of opinions within this group.
