Shaping Sustainable Futures: The Roles of Green Innovation, Green Growth, and Energy Efficiency in Trade-Adjusted Carbon Emissions
Author :
Abstract
This study examines the long-run effects of green growth, green innovation, energy efficiency, and industrialisation on trade-adjusted carbon emissions using panel data from the world's 15 most innovative countries over 2003-2023. Second-generation panel techniques address cross-sectional dependence and slope heterogeneity, with cointegration confirmed via Westerlund's ECM-based tests. SUR, PCSE, and Driscoll-Kraay estimators consistently demonstrate that green growth, green innovation, and energy efficiency significantly reduce emissions, while industrialisation significantly increases them. Dumitrescu-Hurlin causality tests confirm unidirectional causality from the former three to emissions and a bidirectional relationship with industrialisation. Renewable energy expansion, clean technology investment, and energy productivity improvements are effective levers for reducing trade-related carbon emissions. Industrialisation, however, continues to carry a substantial carbon cost even in technologically advanced economies. Governments should integrate carbon pricing and emission standards into industrial policy, while innovation agencies should channel R&D funding toward clean technologies through green procurement and targeted incentive schemes.
