Existing research has insufficiently explored the nexus between the new energy industry and CO2 emissions from the standpoint of export sophistication. This study analyses the implications of the new energy industry’s export sophistication on CO2 emissions, regional heterogeneity, and its influencing mechanism by gathering data from 31 major economies throughout the world between 1996 and 2021. The study found that the new energy industry’s export sophistication helps reduce carbon dioxide emissions, and this conclusion still holds after robustness testing; the carbon emission reduction effect of the export sophistication of the new energy industry is more significant in developed countries than in developing countries; the new energy industry’s export sophistication possesses a crowding-out effect on domestic technological progress, which to a certain extent impedes carbon reduction effect. This paper’s findings provide theoretical guidance for the global low-carbon energy transition.
