“…Using a wide range of methods and tools for implementing sustainable development and renewable energy projects and stimulating CO2 emissions reduction characterizes the global transformational processes in the energy industry. The main ones include legislative norms and restrictions, supporting energy security (Kolosok et al, 2022), implementation of the environmental management system (Dobrowolski et al, 2022;Ziabina et al, 2022), use of emissions trading systems by countries (El Amri et al, 2020), fiscal and tax mechanisms and tools (Bardy et al, 2022;Khalatur et al, 2022), support of ecologically oriented innovative entrepreneurship (Saher et al, 2022); introduction of green investments and taxes (Pimonenko et al, 2018;Vostrykov et al, 2022), environmental standardization and certification; development of sustainable energy consumption (Yang et al, 2021), forming green awareness and sustainable society culture (Kyrychenko et al, 2021;Louis, 2022;Vakulenko et al, 2022). Thus, quite important to investigate the existing scientific environment of developing smart energy sector transformation.…”
