Carbon benchmarking and digital infrastructure are increasingly interconnected in efforts to reduce greenhouse gas emissions and promote sustainable development. Carbon benchmarking involves measuring and comparing the carbon footprint of organizations, processes, or products to identify opportunities for emission reductions. Digital infrastructure—comprising data centers, communication networks, cloud services, and IoT devices—plays a dual role: it is both a significant energy consumer and a critical enabler of carbon management. With the rapid growth of digital technologies, the energy demand of digital infrastructure has surged, prompting the need for benchmarking their carbon emissions. Accurate carbon benchmarking tools leverage big data, AI, and real-time monitoring to assess energy consumption and associated emissions of digital assets. This enables organizations to optimize energy use, transition to renewable sources, and improve operational efficiency. Moreover, digital infrastructure facilitates carbon benchmarking across other sectors by providing platforms for data collection, analytics, and reporting. It supports transparency and compliance with environmental regulations, while fostering innovation in low-carbon technologies. In summary, integrating carbon benchmarking with digital infrastructure is vital for achieving emission reduction targets, enhancing sustainability, and guiding policy development in the digital age.
