Global warming and climate change are global challenges that need a holistic attention and measures to tackle. The potential of environmental technologies and in particular, the role of the information communication society and green technology innovation sector to influence sustainability of the environment has not only courted global attention but also generated a new line of research interests. Given the range of evolving technologies that could play a crucial role toward carbon neutrality by the year 2050, investing in technologies that can be leveraged across households, firms, industries and countries of the world, whose adoption can contribute to mitigation of carbon emissions in the shortest possible time is of significant importance and worthwhile investigating. Broadband of ICT and clean green technology are some of these technologies. This research study employed a dynamic GMM (Generalized Method of Moments) estimator in addition to a battery of static models and other statistical techniques to investigate the impact of broadband and clean green technologies as well as examine the validity of the EKC hypothesis on CO2 emissions in a global context using unbalanced panel dataset of 190 countries to represent the global economy. Given the hypothesis that, emissions and accessibility of these technologies could vary among countries, the research study deemed it relevant to consider levels of development of countries of the global economy by classifying them broadly into two categories: developed countries and emerging-developing countries for further comparative analysis. The empirical results indicated that, overall, at the global level these technologies have mitigating impact on CO2 emissions. At the development levels, while broadband technology had heterogenous outcome in mitigating CO2 emissions between developed and emerging-developing countries, clean green technology had homogenous outcome in mitigating CO2 emissions between the two country groups. Additionally, consistent with the study period and data used, the results further confirmed evidence of the EKC at the global level and for emerging-developing countries in the diffusion of these technologies. The environmental implication of the research findings showed that if broadband technology users and the general ICT sector rely heavily on green materials and energy or electricity consumption produced from clean, renewable sources, a significant chunk of the ICT sector and other anthropogenic footprints could be reduced which will subsequently facilitate the decarbonization efforts of the global environment. Relatedly, the mitigating impact of the indicator measures of clean green technology on carbon emissions discovered in the study consolidated the assertion that widespread development and diffusion of clean green technologies in general can potentially help to reduce over dependence on fossil sources to decarbonize the global economy and improve environmental quality. From policy point of view, the study recommends these technologies not only be considered as important part of global short and long-term policy measures to support climate change mitigation strategies, but also their use maximized at different levels of development. Governments in countries of the global economy should come up with policy measures aimed at providing their private sectors which are critical players when it comes to these technologies development, application and diffusion with the right competitive environment. It is also important at the country levels for both developed and developing countries not to only increase the use of these technologies but should also make them more cheaper and accessible by encouraging investments in them and other emerging green and exponential technologies.ti.
Il riscaldamento globale e il cambiamento climatico sono sfide globali che richiedono un'attenzione olistica e misure da affrontare. Il potenziale delle tecnologie ambientali e, in particolare, il ruolo della società della comunicazione dell'informazione e del settore dell'innovazione delle tecnologie verdi nell'influenzare la sostenibilità dell'ambiente non solo ha attirato l'attenzione globale, ma ha anche generato una nuova linea di interessi di ricerca. Data la gamma di tecnologie in evoluzione che potrebbero svolgere un ruolo cruciale verso la neutralità del carbonio entro il 2050, investire in tecnologie che possono essere sfruttate da famiglie, aziende, industrie e paesi del mondo, la cui adozione può contribuire alla mitigazione delle emissioni di carbonio nel il più breve tempo possibile è di notevole importanza e vale la pena indagare. La banda larga delle TIC e la tecnologia verde pulita sono alcune di queste tecnologie. Questo studio di ricerca ha utilizzato uno stimatore dinamico GMM (Generalized Method of Moments) oltre a una batteria di modelli statici e altre tecniche statistiche per studiare l'impatto della banda larga e delle tecnologie verdi pulite, nonché per esaminare la validità dell'ipotesi EKC sulle emissioni di CO2 in un contesto globale che utilizza un set di dati panel sbilanciato di 190 paesi per rappresentare l'economia globale. Data l'ipotesi che le emissioni e l'accessibilità di queste tecnologie possano variare da paese a paese, lo studio di ricerca ha ritenuto rilevante considerare i livelli di sviluppo dei paesi dell'economia globale classificandoli sostanzialmente in due categorie: paesi sviluppati e paesi in via di sviluppo emergenti per ulteriori analisi comparativa. I risultati empirici hanno indicato che, nel complesso, a livello globale queste tecnologie hanno un impatto di mitigazione sulle emissioni di CO2. A livello di sviluppo, mentre la tecnologia a banda larga ha avuto risultati eterogenei nella mitigazione delle emissioni di CO2 tra i paesi sviluppati ed emergenti in via di sviluppo, la tecnologia verde pulita ha avuto risultati omogenei nella mitigazione delle emissioni di CO2 tra i due gruppi di paesi. Inoltre, coerentemente con il periodo di studio e con i dati utilizzati, i risultati hanno ulteriormente confermato l'evidenza dell'EKC a livello globale e per i paesi emergenti in via di sviluppo nella diffusione di queste tecnologie. L'implicazione ambientale dei risultati della ricerca ha mostrato che se gli utenti della tecnologia a banda larga e il settore ICT in generale fanno molto affidamento sui materiali ecologici e sul consumo di energia o elettricità prodotti da fonti pulite e rinnovabili, una parte significativa del settore ICT e altre impronte antropiche potrebbero essere ridotte che faciliterà successivamente gli sforzi di decarbonizzazione dell'ambiente globale. Relativamente, l'impatto attenuante delle misure dell'indicatore della tecnologia verde pulita sulle emissioni di carbonio scoperte nello studio ha consolidato l'affermazione che lo sviluppo e la diffusione diffusi di tecnologie verdi pulite in generale possono potenzialmente aiutare a ridurre la dipendenza eccessiva dalle fonti fossili per decarbonizzare l'economia globale e migliorare la qualità ambientale. Dal punto di vista politico, lo studio raccomanda che queste tecnologie non solo siano considerate come una parte importante delle misure politiche globali a breve e lungo termine per supportare le strategie di mitigazione dei cambiamenti climatici, ma anche il loro utilizzo massimizzato a diversi livelli di sviluppo. I governi dei paesi dell'economia globale dovrebbero elaborare misure politiche volte a fornire ai loro settori privati, che sono attori critici quando si tratta di sviluppo, applicazione e diffusione di queste tecnologie, il giusto ambiente competitivo. È anche importante a livello nazionale che sia i paesi sviluppati che quelli in via di sviluppo non solo aumentino l'uso di queste tecnologie, ma le rendano anche più economiche e accessibili incoraggiando gli investimenti in esse e in altre tecnologie verdi ed esponenziali emergen

Abstract
Global warming and climate change are global challenges that need a holistic attention and measures to tackle. The potential of environmental technologies and in particular, the role of the information communication society and green technology innovation sector to influence sustainability of the environment has not only courted global attention but also generated a new line of research interests. Given the range of evolving technologies that could play a crucial role toward carbon neutrality by the year 2050, investing in technologies that can be leveraged across households, firms, industries and countries of the world, whose adoption can contribute to mitigation of carbon emissions in the shortest possible time is of significant importance and worthwhile investigating. Broadband of ICT and clean green technology are some of these technologies. This research study employed a dynamic GMM (Generalized Method of Moments) estimator in addition to a battery of static models and other statistical techniques to investigate the impact of broadband and clean green technologies as well as examine the validity of the EKC hypothesis on CO2 emissions in a global context using unbalanced panel dataset of 190 countries to represent the global economy.

The empirical results indicated that, overall, at the global level these technologies have mitigating impact on CO2 emissions. At the development levels, while broadband technology had heterogenous outcome in mitigating CO2 emissions between developed and emerging-developing countries, clean green technology had homogenous outcome in mitigating CO2 emissions between the two country groups.
