This paper contributes to the growing literature regarding the role of Information and Communication Technologies as well as Innovation on driving the level of carbon dioxide emissions and economic growth in context of the 21st conference of the Parties to the Climate convention (COP21). Drawing the data from 13 selected G-20 countries (including Argentina, Canada, China, France, Germany, Italy, Japan, Mexico, Republic of Korea, Russian Federation, Turkey, United Kingdom, United States) during the period of 15 years, our study achieves significant results. First, only five factors impede the carbon emissions namely energy price, foreign direct investment, technology, spending on innovation and trade openness while the remainder of determinants contribute to contamination of environment, including financial development. Second, when it comes to economic growth, information and communication technological and financial development are positive driving factors. Our results do reject the absence of Environmental Kuznets Curve (EKC) from our sample. Finally, our study empirically suggests that the work of controlling consumption of oil and environmentally friendly process including manufacture-trading in these economies will limit the amount of pollution.
