The ongoing energy transition emphasizes the advancement of zero-carbon fuels and low-carbon fuels, including biofuels and alcohol-based fuels, to achieve energy and environmental sustainability. However, it is crucial to assess the emissions and potential environmental impacts associated with these alternative energy sources.

This book explores the role of sustainable fuels in reducing environmental pollution, with particular focus on second and third generation biofuels. It describes advances in sustainable fuel production technologies, examines the challenges posed by pollutants generated during their use, and presents strategies for managing these issues. Additionally, it discusses the importance of proper system operation and maintenance to ensure optimal performance.
