The global goal of the world community is the transition to a green economy, characterized by rational use of electricity, reduction of harmful emissions, and consumption of renewable energy sources. The purpose of the research was to study the convergence of capacity emissions in developing countries to European countries' level. According to the results, countries striving for a lower emission intensity level to varying degrees. In non-OECD European countries, per capita income growth leads to a 0.26% reduction in emissions intensity. This fact means that economic growth creates additional resources that can be used to develop energy-efficient technologies. In the post-Soviet space and the Asia-Pacific region, a significant effect on reducing emission intensity is provided by environmental policy's effectiveness to minimize carbon dioxide emissions.
