Dedicated refurbishment facilities and transportation links allow assets like consumer electronics to be restored, extending useful lifetimes. 

  • Asset-sharing platforms

Shared access models like product-as-a-service shift incentives from one-time transactions to continual asset utilization. Instead of single owners, products and services are provisioned within pooled systems targeted at many users, like car sharing.

Sustainable sourcing and procurement

As companies seek to reduce their environmental footprints, setting clear sustainability expectations for suppliers is a fundamental first step. This greatly contributes to sustainable logistics and supply chain management.

  • Responsible sourcing policies

Formal responsible sourcing policies codify environmental and social standards that suppliers must meet. These policies typically prohibit unauthorized deforestation, harmful emissions, and unethical labor practices. They also outline sustainability criteria for raw materials and production methods. A recent regulation influencing sustainable procurement is the Single-Use Plastics (SUP) Directive, designed to mitigate the effects of plastic products and encourage a shift towards a circular economy.

  • Ongoing assessments

Beyond initial screening, regular sustainability assessments provide visibility into supplier practices. Self-assessment questionnaires allow suppliers to report on key metrics like energy usage, waste generation, and compliance with labor regulations. More rigorous third-party audits may also be conducted periodically to verify sustainability performance.

  • Partnering with suppliers

Rather than simply policing suppliers, forward-thinking companies collaborate with vendors to implement cleaner production processes. Apparel brand Levi’s has introduced Water<Less™ – an innovative technology allowing to reduce water consumption by up to 96% during finishing. This has already saved billions of liters of water.

Sustainable transportation

Transportation has been greatly affecting the state of the environment. For instance, in the EU, it generates nearly a quarter of total supply chain emissions. That’s why curbing the climate impact and shifting to sustainable logistics is an urgent priority. 

  • Investing in low-emission vehicle fleets

Electrifying distribution vehicles dramatically lowers lifecycle emissions compared to diesel trucks. Thus, IKEA has set an aim to introduce a 100% electric last-mile delivery fleet across 30 markets by 2025. Transitioning to renewable electricity for charging enables further reductions. 

  • Intermodal transport efficiencies

Leveraging intermodal transport that combines rail and truck minimizes emissions for long hauls. Shifting freight transport from air to rail can drastically reduce carbon footprints between regions like Asia and Europe. Using ships to carry containers back after initial delivery eliminates wasted capacity from empty returns. Expanding usage of these multi-modal options significantly cuts logistics emissions.

  • Route optimization

Using route optimization platforms analyzes factors like terrain and traffic to generate the most fuel- and time-efficient transit plans. Optimized routing considering vehicle load sizes and road conditions can reduce total kilometers driven, lowering fuel consumption and costs. Switching to electric vehicle fleets would provide additional savings on top of route efficiency gains.

  • Partnering with IT providers for enhanced sustainability

Top-notch IT agencies specializing in logistics solutions can provide technologies to track supply chain sustainability, assisting companies in benchmarking and reducing emissions. 

  • Industry collaboration 

Groups that convene companies across retail, logistics, and transportation aim to jointly address emissions from freight movement. By aligning policy priorities and scaling the adoption of eco-friendly logistics across sectors, these collaborative initiatives can accelerate decarbonization industry-wide. 

Green packaging

As sustainable logistics companies aim to shrink their environmental footprints, innovating eco-conscious packaging presents a major opportunity. 

  • Maximizing recycled and renewably-sourced materials

Sourcing post-consumer recycled content minimizes waste while reducing the need for virgin natural resources. Cardboard boxes made from 100% recycled paper prevent additional tree harvesting and cut oil and CO2 emissions by 60%. Some manufacturers even upcycle used cardboard into cushioning inserts, giving materials extended life. Further, biodegradable bio-plastics from plant starches or microorganisms offer plastic alternatives without depleting finite oil reserves.

  • Optimizing package and pallet dimensions

With transport emissions tied to weight and cube utilization, optimizing box and pallet dimensions cuts waste and fuels savings. Analyzing common parcel sizes to perfectly fit products helps to avoid oversized containers and excess void fill. Stackable, interlocking transport packaging with a smaller footprint also enables more efficient cargo loading. 

  • Reimagining distribution networks to enable reuse

Large volumes of single-use transport packaging end up in landfills annually. However, reusable systems with return logistics offer circular solutions. Sustainable logistics companies are investing in developing pooled containers like crates and pallets that continually rotate among sites. Others reclaim used parcels to recondition and reuse. Though requiring upfront infrastructure, these closed-loop models minimize waste over time.

  • Piloting creative multi-use concepts

Stretching packaging functionality further, inventive hybrid designs serve various needs across supply chains. For example, reusable plastic envelopes can be transformed into cardboard shipping boxes after delivery. Post-use, the mailer pockets fold back flat for return transit as envelopes again. Such multipurpose packaging promotes circularity from end to end.
