The journey to sustainable logistics is illustrated by three critical stages. The reporting effect focuses on accurate data collection for CO2 reporting to minimize risks of over-reporting. The transparency effect focuses on an end-to-end transparent supply chain and enables targeted improvements in emissions. Leveraging this transparency, the network effect promotes strategic decisions such as building efficient supply networks to reduce costs and reduce CO2 emissions through resource sharing. Together, these stages highlight the importance of accurate data, informed decision-making, and collaboration in driving sustainable practices in the logistics industry.
