The escalating threat of climate change, driven largely by anthropogenic greenhouse gas emissions, has intensified global attention on carbon footprint analysis and reduction strategies. This review presents a multidisciplinary analysis of the sources, types and sector-specific impacts of greenhouse gas emissions, focusing on energy, transportation, industrial business, agriculture, buildings and waste management. It explores the evolving concept of the carbon footprint and evaluates strategies for its reduction through technological innovations, behavioral change and policy mechanisms. Emphasis is placed on emerging solutions such as clean energy systems, low carbon infrastructure, carbon capture and storage and circular economy practices. By integrating multidisciplinary insights, the paper identifies challenges, opportunities and future directions for achieving substantial carbon mitigation and supporting the transition toward low carbon and climate resilient systems.
