Digital technology, including advancements in artificial intelligence, the Internet of Things, and data analytics, has the potential to revolutionize tackling the problem of carbon dioxide emissions and achieving sustainable development. The paper aims at checking the nature of the impact of digital technology development on carbon dioxide reduction for the EU countries in 2013–2020. The study applies the following methods: entropy methods, panel‐corrected standard error, and feasible generalized least squares. The digital technology development index enabled the classification of all the EU countries into two distinct groups: High Digital Technology Development and Moderate/Lower Digital Technology Development. The findings confirm that digital technology development has a significant impact on decreasing carbon dioxide emissions. In the first stage, the growth of digital technology causes a faster decrease in carbon dioxide emissions. However, beyond a certain threshold, the further improvement of digital technology results in diminishing marginal benefits of CO2 emissions reduction. Thus, the EU government should catalyze the extension of digital technologies among all sectors and levels. In addition, it requires enhancing digital literacy of the society and local authorities.

了解数字技术发展对二氧化碳减排的非线性影响

数字技术，包括人工智能、物联网和数据分析的进步，有可能彻底改变解决二氧化碳排放问题和实现可持续发展。该论文旨在检验2013-2020年数字技术发展对欧盟国家二氧化碳减排影响的性质。该研究采用了以下方法：熵方法、面板校正标准误差和可行的广义最小二乘法。数字技术发展指数将所有欧盟国家分为两个不同的组：高数字技术发展和中/低数字技术发展。研究结果证实，数字技术发展对减少二氧化碳排放具有重大影响。第一阶段，数字技术的发展导致二氧化碳排放量更快减少。然而，超过一定阈值后，数字技术的进一步完善会导致二氧化碳减排的边际效益递减。因此，欧盟政府应促进数字技术在各个部门和各个层面的推广。此外，还需要提高社会和地方当局的数字素养。
