Pro-environmental attitudes are important in consumers' decisions to purchase and use environmentally friendly products that directly contribute to the reversal of environmental degradation. Cognitive values, which are accepted as an important indicator of protecting the environment, and extrinsic motivation elements that lead to exhibit environmentally friendly behaviors are effective factors in exhibiting pro-environmental attitudes. Environmental attitude, which is a very important construct in environmental psychology, is the sum of beliefs, emotions and behavioral intentions that a person has about environmental activities or issues. In this regard, the purpose of the study is to examine the cognitive values of green products and the effect of green extrinsic motivation on environmental attitudes. Another purpose of the research is to test whether environmental attitudes differ according to demographic characteristics and frequency of purchasing green products. In the study, data were obtained from 289 respondents using the online survey technique. In the analysis of the data, explanatory factor analysis, correlation, regression, independent sample t-test and one-way analysis of variance were used through the SPSS package program. As a result of the analyzes, it was determined that the role of the state from cognitive values and green extrinsic motivation dimensions has a positive effect on environmental attitude. In addition, it was concluded that environmental attitude differs according to gender, education and occupation, but does not differ according to age, income, marital status and frequency of purchasing green products.
