An Introduction to the Top 6 Technologies

Before we dive into the specifics of each technology, let‘s briefly introduce how they drive supply chain sustainability and some adoption stats:

  • Cloud-based ERP: Real-time visibility into emissions and automated data collection to optimize logistics, packaging and inventory. Potential to reduce supply chain emissions by 5-10%.
  • Smart Devices: Precisely monitor assets to minimize energy usage and fuel consumption. Can lower facility emissions by 20% or more.
  • 3D Printing: Manufacture parts locally rather than transporting globally. Reduces emissions from transport by up to 80%.
  • Electric Vehicles: Eliminate tailpipe emissions for last-mile and long-haul transportation. Decrease CO2 per km by ~2.5X compared to diesel.
  • AI Optimization: Improve forecasting, route planning and warehouse operations. Can reduce transport emissions by 10-20%.
  • Blockchain: Provides transparency for sourcing, emissions and compliance data. Increases accountability across supply chains.

While upfront investment is required, research shows payback in less than 3 years through costs savings and avoided emissions penalties in many cases. The following sections explore the details…

1. Cloud-Based ERP Systems

Enterprise resource planning (ERP) platforms have long helped companies manage core supply chain operations from production to inventory to transportation. But legacy ERP systems rely on manual data entry which does not provide the real-time climate insights needed today.

Newer cloud-based ERP systems solve this through automation and built-in emissions tracking. Rather than supply chain managers piecing together sustainability data, the ERP platform does it instantly through digital connectivity.

Key advantages of cloud-based ERP for sustainability:

  • Real-time visibility: Continuous insights into orders, inventory and logistics emissions rather than periodic reporting.
  • Automated emissions tracking: ERP systems can calculate emissions from transport miles, warehouse energy, manufacturing, etc. based on activity data.
  • Scenario modeling: Simulate the environmental impact of different supply chain network and packaging changes.
  • Benchmarking: Compare emissions and energy usage across facilities and business units to identify improvement opportunities.
  • Lower IT footprint: Cloud platforms have 98% lower carbon emissions than legacy on-premise servers and data centers.

Leading ERP providers like SAP, Oracle, Infor and Microsoft now offer sustainability modules. For example, consider global brewer AB InBev:

  • Implemented SAP’s ERP system with carbon accounting integration
  • Real-time visibility reduced supply chain emissions by 9% in just 2 years
  • Optimized distribution routes and packaging materials based on insights

The payback period for implementing supply chain emission tracking in ERP is estimated at less than 12 months according to Nucleus Research due to cost savings and emissions penalty avoidance.

However, integrating sustainability metrics into complex global ERP deployments requires upfront effort and change management. Supply chain managers should involve IT teams early on and identify high impact use cases.

2. Smart Devices and Sensors

The Internet of Things (IoT) allows companies to add sensors and connectivity to assets across the supply chain. Equipment that was previously “blind” can now provide rich data to optimize sustainability. Use cases include:

Smart energy sensors – Monitor energy consumption from lighting to HVAC systems in warehouses, plants and offices. Machine learning algorithms crunch the data to minimize electricity usage while maintaining employee comfort and safety. Intel used this approach to cut energy costs by $19 million annually across its factories.

Fleet telematics – Install GPS trackers on vehicles to collect data on driver behaviors like sudden acceleration and hard braking that waste fuel. Combine with route optimization algorithms to improve mileage efficiency. UPS reduced 100 million miles driven annually through its AI-powered ORION platform analyzing telematics data.

Automated inventory tracking – RFID tags on pallets and products enables real-time inventory visibility. This reduces energy for unnecessary handling as well as product spoilage and obsolescence. UK retailer The Co-Op cut warehouse emissions by 42% by using RFID to improve stock management and turnover.

Early adopters of supply chain sensor networks and automation such as Amazon and Walmart have seen ROI in less than 18 months according to McKinsey. The payback includes energy savings plus labor cost reductions from optimized workflows.

Supply chain managers should start with a pilot projectfocused on a single facility or fleet before scaling IoT initiatives more broadly. Getting employee buy-in to adopt new technologies is also crucial.

3. 3D Printing for On-Demand Manufacturing

3D printing, also called additive manufacturing, builds objects layer-by-layer from digitally-controlled machines. This enables on-demand production without costly tooling and molds. Rather than waiting weeks for overseas shipments, parts can be printed where and when they are needed.

Studies by MIT and Singapore University show 3D printing reduces supply chain carbon emissions by 70-80% for plastic parts and up to 96% for metal parts. This is achieved by:

  • Localizing production closer to point of use rather than shipping globally
  • Optimizing designs for 3D printing by using less material and consolidating subcomponents
  • Enabling small batch production so inventory volumes can be lower
  • Minimizing waste since only the required amount of material is used

While 3D printing is still maturing, major companies are adopting the technology:

  • Athletic shoe brands like Adidas and New Balance use 3D printing for prototyping and some production runs. This allows customization plus lower emissions.
  • Boeing prints over 300 unique parts on aircraft including brackets and ventilation ducts. This reduces lead times while maintaining quality control.
  • Auto parts supplier Continental 3D prints certain prototypes at headquarters rather than sourcing from Asia suppliers thousands of miles away.

According to consulting firm Bain, 3D printing can reach adoption rates above 50% for industries like aerospace, medical devices and automotive within 5-7 years as printer performance keeps improving.

4. Electric Vehicles for Green Logistics

Replacing diesel trucks and vans with electric vehicles can significantly lower supply chain emissions. EVs have no tailpipe exhaust allowing a silent, zero-emissions delivery experience. Beyond environmental aspects, EVs also have lower operating costs over the vehicle lifetime.

Studies by leading universities show electric vans and trucks reduce CO2 emissions by approximately 2.5X per kilometer compared to diesel counterparts when charged with green energy sources. Supply chain leaders are recognizing this:

  • Amazon ordered 100,000 custom electric vans for last-mile delivery, aiming to be net-zero carbon by 2040.
  • IKEA purchased 170 electric trucks for home deliveries across Europe with plans for a 100% EV fleet by 2025.
  • Shipper DB Schenker transitioned 250,000 packages per day to electric vehicles across German cities reducing CO2 by over 36,500 tonnes per year.

The higher upfront cost of electric trucks and vans has dropped rapidly. EVs now have 5-10% lower total cost of ownership than diesels due to lower electricity fueling costs and reduced maintenance. Supply chain managers have the opportunity to select EVs strategically for urban routes ready for charging infrastructure.

5. AI and Machine Learning Optimization

Artificial intelligence (AI) and machine learning unlock major potential to reduce supply chain emissions through optimization algorithms and predictive analytics. Use cases span:

Smarter forecasting – AI aggregated demand data across markets, social media and search trends to anticipate needs more accurately. Unilever improved product forecasting by 10-15% using AI according to Accenture, optimizing production and inventory.

Route optimization – Machine learning models incorporate traffic, weather, delivery density and other variables to plan the most efficient routes possible. Google Maps uses this to offer the greenest routes lowering emissions by up to 10% for long-haul trucking.

Predictive warehouse maintenance – Algorithms flag potential equipment failures before they occur by analyzing sensor data. This avoids energy waste from operating sub-optimal machinery. McKinsey estimates 20% energy savings in warehouses from predictive maintenance.

The most sophisticated supply chains already leverage AI, but adoption is still below 10% globally. Barriers include lack of data infrastructure, AI skills and difficulty integrating algorithms into complex legacy systems. But machine learning will become essential to maximize assets, minimize waste and reduce emissions.

6. Blockchain for Supply Chain Transparency

Blockchain offers a decentralized digital ledger for recording transactions and tracking goods across supply chains. This cryptographic approach verifies data while sharing information across the ecosystem. Rather than siloed records, blockchain provides end-to-end transparency from raw materials to consumers.

For sustainability, blockchain is invaluable to trace key metrics including:

  • Sourcing – Track raw materials to verify responsible harvesting claims such as palm oil certifications. Records are immutable to prevent tampering.
  • Manufacturing – Ensure compliance with emissions regulations and labor policies across tier 1, 2, 3+ suppliers. All parties participate in the digital chain.
  • Transportation – Document real-time location and condition data for goods in transit to minimize waste. Smart contracts can flag issues.
  • Carbon accounting – Share emissions data across supply chain boundaries for total footprint insights from farm to disposal.
  • Circularity – Record recycling rates, reuse percentages and end-of-life handling to measure closed loop progress.

Diamond company De Beers tracks stones from mines to retailers using blockchain to verify responsible sourcing. Walmart uses it to monitor food from suppliers globally.

While blockchain is still maturing, it provides a “trustless” method to increase accountability across value chains. Integrating with IoT networks creates even more potential to verify goods as they move between parties.
