Environmental degradation caused by various human activities has been a subject of attention over the globe. There is a concern on how to maintain a clean environment and at the same time achieve optimum production of food and non-food products amidst global energy demand. To this end, this study examines the impact of agricultural development, energy use and economic growth on CO2 emissions in the emerging seven countries that comprises China, India, Brazil, Mexico, Russia, Indonesia and Turkey for the annual time frequency from 1990 to 2016. The study uses a battery of econometrics techniques for soundness of analysis the consist of Pooled MeanGroup-Autoregressive Distributed Lag methodology, Dynamic Ordinary Least Squares and Fully Modified Ordinary Least Squares as estimation techniques alongside Dumitrescu and Hurlin Causality Test for the direction of causality analysis. Empirical results revealed that Agricultural value-added and economic growth are drivers of CO2 emission in the E7 countries while the rise in renewable energy causes a reduction in CO2 emissions. While in the short-run, economic growth has a positive impact on emissions in the focus countries. While causality analysis shows that there is a feedback causality between economic growth and emissions, agriculture value-added and energy usage, emission and agriculture value-added as well as economic growth and agricultural development. Furthermore, energy use does not cause emissions directly, it causes economic growth and agriculture value-added which causes emissions. This position aligns with the advocacy of the United Nations Sustainable development goals (UN-SDGs) targets 7 and 13 of clean energy access and mitigation of climate changes issues.
