The environmental effects of urbanization and globalization are still subject to debate among scholars. South Africa is the most globalized, most urbanized and the most carbon-intensive economy in Sub Saharan Africa (SSA) region. Taking this into cognizance, this study examines the effects of urbanization and globalization on CO 2 emissions for South Africa using time series annual data for the period 1980–2017. Zivot and Andrews single and Bai and Perron multiple structural break unit root tests are employed to assess if all the series are stationary. This procedure follows ARDL cointegration test to check the presence of a long-run association among variables. Having been confirmed about such a cointegrating relation, ARDL short-run and long run coefficients indicate that urbanization induces CO 2 emissions while only long-run significant emissions effect of globalization was noted. Toda-Yamamoto non-causality test reports a bi-directional causal link between urbanization and CO 2 emissions. No causal link is observed between globalization and CO 2 emissions. Variance decomposition results do not rule out these effects in future. Policy implications are discussed.

Purpose This study aims to investigate the relationship between organizational citizenship behavior for the environment (OCBE) of managers and the constructs of the theory of planned behavior: perceived behavioral control (PBC) and attitude toward the environment. The current study also aims to explore the magnitude of this relationship with subjective norms as a moderating variable. Design/methodology/approach Data were sourced from a total number of 140 respondents (managers) from different firms in The Netherlands through an online questionnaire by using a mixture of structured, semi-structured and open-ended questions. Having used the correlation test, the study first conducts the exploratory factor analysis and then the reliability test. Finally, it estimates the coefficients by applying the hierarchical regression model to find the relationship between dependent and explanatory variables. Findings Diagnostic test results revealed that data are highly reliable. The coefficient results indicate that PBC and environmental attitude have positive and significant relationships with OCBE. Additionally, subjective norms have a significant and positive effect on strengthening the relationship between PBC and OCBE; however, it has no impact on the relationship between environmental attitude and OCBE. Research limitations/implications This study has some caveats. First, the results presented in the research are derived from a single moment in time. The second limitation has to do with the insignificant results for the construct of environmental attitude. Third, this study comprises a data set obtained from different companies in The Netherlands. Practical implications Organizations that want to increase their environmental performance could look at the PBC, environmental attitude and subjective norms of the managers in regard to OCBE. Originality/value The results of the study contribute to the understanding of the way PBC, environmental attitude and subjective norms positively affect OCBE. Future research should investigate organizational citizenship within business firms by considering corporate social responsibility as a key variable.
