The use of digital technology in agriculture, such as sensors, satellites, and artificial intelligence, for developing sustainable agriculture and controlling the impacts of climate change, has been enhanced under the European Green Deal. Given the environmental exigencies, the agricultural sector must adapt to new technologies that ensure the sustainable development of the whole agri-food sector. This paper emphasizes the importance of measuring carbon footprints in agriculture as a tool for further improving the sustainability of the sector. Specifically, the research addresses the importance of sustainable technologies and practices, including agriculture, circular economy, and conservation agriculture, which play an important role in reducing carbon emissions from the agricultural sector. Thus, in the framework of the European Green Deal and digitalization, a bibliographic analysis was carried out using the Web of Science database to review the scientific interest on carbon footprint generated by farms. The aim of the paper is to tackle the significance given by the scientific community on the carbon footprint of farms in order to enhance the development of a comprehensive set of measures that can incorporate the sector’s social and environmental responsibility, and ensure further the right path towards a sustainable future without affecting the profitability of the small farmers.
