Abstract

<p>The growing dependence on fossil fuels in the agriculture sector—particularly through the use of mechanized farm equipment—has contributed significantly to global carbon dioxide (CO₂) emissions, compounding climate change concerns and challenging the sustainability of food production systems. This review critically examines the key contributors to carbon emissions in agricultural mechanization and evaluates technological maturity in relation to energy use patterns and fuel consumption in conventional farming practices. The study aims to provide a structured roadmap for decarbonizing the agricultural supply chain, emphasizing how a transition to renewable energy technologies (RETs) and energy-efficient machinery can reduce the environmental impact of farm operations. By analyzing current frameworks and predictive models, the research identifies strategies to align agricultural machinery with renewable energy sources while considering the dynamic load demands of agrarian activities. Rather than prescribing a single solution, the review advocates for a diversified approach that leverages all viable options—technological, operational, and policy-based—tailored to the specific capacities and contexts of farmers. It argues that meaningful CO₂ mitigation in agriculture is achievable through a combination of renewable energy integration, mechanization efficiency improvements, and sustainable fuel alternatives. Furthermore, the manuscript highlights that significant CO₂ reductions are possible when decarbonization strategies are embedded across the entire mechanization process—from land preparation to harvesting. It calls for policymakers, practitioners, and agricultural stakeholders to adopt comprehensive energy transition strategies that are economically feasible, environmentally sound, and practically adaptable to varying agricultural systems. In conclusion, this study offers an evidence-based foundation for rethinking energy consumption in agricultural production and presents actionable insights toward achieving sustainable, low-carbon farming systems without compromising food security or economic growth</p>
