This study examines environmental technical efficiency (ETE) and the technology gap ratio (TGR) for a panel of the OECD countries over the period 2000-2019, using stochastic meta-frontier analysis. The results indicate that EU-OECD countries, particularly the newer members, are generally more efficient, suggesting potential gains in GDP and reductions in CO2 emissions. The results suggest that non-EU OECD developing countries outperform developed countries. The meta-frontier analysis further reveals that EU-OECD countries exhibit higher meta-technical efficiencies attributable to more stringent regional environmental policies. The TGR analysis indicates that EU-OECD countries are closer to the meta-frontier than non-EU OECD countries, suggesting a smaller technology gap. These findings underline the significance of regional policies in promoting ETE and technology development within diverse economic and regulatory frameworks. The Tobit regression results indicate that the environmental policy stringency index has a positive impact on TGR and promotes technological progress; however, it does not have a significant impact on meta-technical efficiency. This suggests that while the adoption of stringent regulations may promote the adoption of environmentally friendly technologies, it may also hinder efficiency if existing technologies are unable to meet the new standards. The analysis further indicates a positive relationship between renewable energy consumption and TGR.
