Pro-environmental behavior is a broad construct of individual activity that minimizes harm to or benefits the environment. Different researches have given different terminology for different aspect of those environment oriented behavior. Present research compares between the three different constructs of pro-environmental behavior at workplace which has been extensively researched upon in the last decade- employee green behavior, voluntary workplace green behavior and organizational citizenship behavior towards environment. Theoretical comparisons of the three variables were done. Comparisons among the three variables were also done by collecting data using measures of three variables. Data was collected from 234 employees from chemical manufacturing firm. Factor analysis was done to find out factors. Result of factor analysis showed similarities among the variables. The items of three scales loaded into three factors – daily pro-environmental activities, lesser consumption of resources and alternative pro-environmental steps. The similarities among the variables along with theoretical contribution are discussed. Comparison among three major initiatives have been done.. A comprehensive tool which has been suggested can be used by future researchers to measure environmental behavior at workplace.

Purpose Based upon the broaden-and-build theory of positive emotions, this study aims to assess the role of perceived social responsibility (PSR) in mediating the relationship between gratitude and environmentally responsible behaviour (ERB) among teachers. Design/methodology/approach Data were collected, following a correlational design, from a total of 292 school teachers in Kerala state, India. In total, 256 data were taken for final analysis. Out of the total participants, 63.3% were female and the remaining 36.7% were male. Confirmatory factor analysis was carried out to verify the factor structure and discriminant as well as convergent validity of the study variables. The relationship between gratitude and ERB with mediating role of PSR was tested. Findings The mediation analysis output revealed that PSR fully mediates the effect of gratitude on ERB, and it is concluded from the findings of the study that ERB can be enhanced by humanizing the citizens to integrate social responsibility in their acts and promoting the significance of having positive emotions like gratitude to widen their thought–action repertoires. Research limitations/implications In line with the broaden-and-build theory, a positive state of mental faculty can be a prime facilitator to increase concern for green environments as an outcome of an expanded thought–action repertoire. The findings imply the importance of inculcating enduring personal resources like the sense of gratefulness as it weighs the effect of producing altruistic acts like ERB along with many other benefits associated with having a positive emotion which is obviously considered to be a fair contribution to serve social resources in the community. Social implications The study findings can be an inspiration for the formation of policies to encourage pro-environmental behaviour and to further expansion of policies like national education policy of India. As teachers being the facilitators of knowledge and wisdom, they are potential sources to inspire students to practice healthy behaviours, they can be better models by practicing ERB. Originality/value The authors have verified the application of broaden-and-build theory of positive emotion in the context of ERB along with identifying its relationship with gratitude and PSR.
