The literature identifies several key green logistics strategies employed by companies to reduce their environmental impact. These include optimizing transportation routes to minimize fuel consumption and emissions, using eco-friendly vehicles such as electric or hybrid trucks, and improving energy efficiency in warehouses through the use of renewable energy sources and energy-efficient lighting and heating systems. Additionally, reverse logistics, which involves the collection and recycling of products and packaging, is a crucial strategy for managing waste and promoting a circular economy (Govindan et al., 2015). Technological advancements play a critical role in enabling green logistics. Innovations such as telematics, GPS tracking, and data analytics allow companies to monitor and optimize their logistics operations in real time. For instance, route optimization software can identify the most efficient routes, reducing fuel consumption and emissions. Similarly, advanced warehouse management systems (WMS) can optimize storage and retrieval processes, minimizing energy use and improving operational efficiency (Kumar & Chandrakar, 2012). Collaboration and partnerships are also essential for the successful implementation of green logistics strategies. Companies often collaborate with suppliers, logistics providers, and other stakeholders to share best practices, develop joint initiatives, and leverage synergies. For example, some companies participate in collaborative transportation initiatives, where multiple companies share transportation resources to reduce empty miles and improve load efficiency (Wolf & Seuring, 2010). Despite the benefits of green logistics, companies face several challenges in implementing these strategies. One of the primary challenges is the high initial investment required for green technologies and infrastructure. While these investments can lead to long-term cost savings and environmental benefits, the upfront costs can be a significant barrier, especially for small and medium-sized enterprises (SMEs) (Tachizawa et al., 2015). Additionally, the lack of standardized metrics and reporting frameworks for measuring and communicating the environmental impact of logistics activities can hinder the adoption of green logistics practices. The integration of sustainability (Emon & Khan, 2023), entrepreneurship (Emon & Nipa, 2024), emotional intelligence (Emon et al., 2024), marketing (Rahman et al., 2024), and supplier relationship management (Emon et al., 2024) into supply chain practices underscores the multifaceted nature of sustainable supply chain management. These dimensions highlight the importance of a holistic approach that considers various internal and external factors in enhancing sustainability. In conclusion, the literature on green logistics strategies provides valuable insights into the drivers, strategies, and challenges associated with sustainable supply chain practices. By integrating environmental considerations into logistics operations, companies can reduce their carbon footprint, enhance their reputation, and gain a competitive advantage. However, the successful implementation of green logistics requires overcoming challenges such as high initial investments and the lack of standardized metrics.
