Global decarbonization efforts have intensified interest in the integration of renewable energy, carbon management & green tech across industrial and policy sectors. Solar photovoltaics, wind turbines, green hydrogen, and advanced bioenergy are reshaping global energy portfolios, while carbon capture, utilization, and storage (CCUS) technologies gain momentum as transitional tools. The sector also encompasses smart grids, energy storage innovations, and lifecycle carbon accounting to ensure net-zero ambitions are technically and economically viable. Meanwhile, green technologies—from eco-efficient manufacturing to climate-friendly refrigerants—are enabling a broader shift toward environmentally conscious industry. The research domain of Renewable Energy, Carbon Management & Green Tech stands at the intersection of innovation, energy justice, and planetary boundaries, driving a clean energy future. Emerging economies are now central to this transition, offering testbeds for scalable solutions and inclusive growth. International cooperation and investment in green R&D will be vital to accelerating momentum.
