E-commerce has revolutionized the way in which businesses operate and customers shop. With the growing demand for online shopping, retailers are continuously looking for ways to enhance their supply chain efficiency while also meeting sustainability goals. This is where sustainable e-commerce technologies come into play. The use of these technologies in the supply chain can have a significant impact on both efficiency and sustainability goals. One key aspect is the implementation of cloud-based systems, which can improve inventory management, reduce lead times, and minimize waste by streamlining processes. As the demand for online shopping continues to rise, it has become crucial for businesses to address the sustainability concerns related to their e-commerce operations. The use of advanced sustainable technologies in this sector has the potential to increase both supply chain efficiency and help achieve sustainability goals. This abstract aims to highlight how sustainable e-commerce technologies can impact both these factors. Firstly, incorporating sustainable technologies such as cloud computing, artificial intelligence, and block chain can greatly enhance supply chain efficiency. Cloud computing allows for real-time collaboration between different stakeholders within the supply chain, reducing communication delays and improving overall coordination. Artificial intelligence can optimize processes like inventory management and route planning, leading to reduced transportation emissions and improved delivery times. Additionally, block chain technology provides transparency by allowing all parties involved in a transaction to view relevant information, leading to more efficient decision-making.
