The paper aims to identify prospects for improving the regulation of smart green innovations to maximize their contribution to combating climate change. The research is based on a mathematical apparatus and Numbeo and WIPO statistics for 2022. The author applies the regression analysis method to determine the climate index’s dependence on factors such as environmental quality certification in the economy, the freedom of international trade, diversification, and market size. A scenario analysis of climate change up to 2024 is carried out. As a result, the author concludes that environmental certification is a much more effective mechanism for combating climate change than ensuring market freedom. The prospects for better regulation of smart green innovations to maximize their contribution to the fight against climate change are related to the development of environmental certification. It is advisable to reinforce environmental certification with the eco-design of products. On this basis, the author proposes a new approach to regulating the practice of creating and implementing smart green innovations based on eco-design and environmental certification of product quality in the economy. The new approach to developing eco-design of climate-resistant products recommends combining the latest achievements of science with creativity and art. This will create the most vibrant, informative, and attractive eco-design. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
