Carbon neutrality in transportation: In the context of renewable sources

GHGs significantly impact climate change, adversely affecting both the environment and human well-being. As energy production and transportation are among the primary contributors to these emissions, many nations have implemented strategies to transition to renewable energy and reduce emissions by 2050-2070. This review focuses on identifying effective policies and pathways to achieve carbon neutrality in the transport supply chain. A bibliometric analysis highlights the growing importance of hydrogen and biomass-generated energy. Key trends include alternative fuels, hydrogen, electric vehicles, solar and wind energy, carbon neutrality, and GHG mitigation. In both the short and long term, integrating green transportation innovations, renewable energy consumption, and sustainable economic growth can substantially lower carbon emissions. Factors such as population growth, urbanization rates, coal consumption, renewable energy adoption, and the increasing use of electric vehicles (EVs) are emerging as critical drivers of environmental sustainability and net-zero emission goals. Policymakers are strongly encouraged to prioritize and implement optimal strategies that capitalize on these opportunities to advance carbon neutrality objectives.
