Is ecological personality always consistent with low-carbon behavioral intention of urban residents?

In the field of low-carbon economics, researchers have become interested in residential consumption as a potential means for reducing carbon emissions. By analyzing and expanding the fundamental concept of personality, a type of personality, namely ecological personality (EP), was defined and a structural model of EP was constructed based on a five-factor model. The study surveyed 890 urban residents to examine the relationship between EP and low-carbon behavioral intention (LCBI). Ecological personality is a five-dimensional concept comprising eco-neuroticism, eco-agreeableness, eco-openness, eco-extraversion, and eco-conscientiousness. Ecological personality traits were positively correlated with the LCBI. However, a quadrifid graph model showed that the EP is not always consistent with LCBI, and respondents fell into two groups: one group comprised ecological residents with consistent traits (positive EP and high LCBI) and non-ecological residents with consistent traits (negative EP and low LCBI), and their EP was consistent with LCBI; the other group comprised ecological residents with gap traits (positive EP and low LCBI) and non-ecological residents with gap traits (negative EP and high LCBI), and neither showed any consistency between personality and intentions. A policy to guide the conversion of different groups into ecological residents with consistent traits is discussed.
