In recent years, a pandemic, geopolitical tensions and economic pressures have combined to expose significant vulnerabilities and disruptions in supply chains around the world. We’ve learned how important it is to build resilience into our supply chains, not only to address the most immediate challenges, such as identifying the sources of materials and goods produced, as well as managing rising costs and fulfillment delays, but also to also support a sustainable, equitable future.

Reducing carbon emissions is also a key pillar in creating a sustainable global supply chain. Advanced digital technologies such as artificial intelligence (AI), smart sensors and blockchain help generate the real-time data, analytics and business intelligence that create resilience, and give organizations a foundation for tackling carbon emissions by providing a comprehensive view of their carbon footprint across the entire value chain.

A material advance in data-driven supply chain transparency

Supply chains are the backbone of the global economy, and organizations need transparency across their supply chains to make informed decisions that enable sustainable practices. Many companies have supply chains which are less than transparent and lack visibility beyond the first (direct vendor) or second tier (subcontractor to a vendor) of their supply chain. This leaves them vulnerable to risks they can’t anticipate or adapt to quickly, as well as unable to ensure responsible, sustainable sourcing and production.

Hitachi has partnered with Circulor, a leading provider of industrial, complex supply chain traceability solutions so organizations can track their entire supply chain and have visibility into critical scope 3 emissions. Based on AI and blockchain technology, the technology “illuminates” the supply chain, creating transparency not only across all tiers of vendors, but also across the physical materials that are part of the manufacturing process.

Organizations can visualize and track their entire supply chain on a single dashboard, drilling down into such factors as each supplier’s greenhouse gas emissions ratings. Companies can use these insights to make informed decisions to improve their sustainability while also increasing their ability to stay compliant with regulatory changes.

Equally important, this granular approach to supply chain transparency helps companies transition to the circular economy.

Smart Supply Chain Management and Optimization Technologies

A sustainable shift from linear to circular manufacturing

The age of extracting raw materials from the Earth and discarding the resulting products at the end of their useful lives — where they deteriorate in landfills or in the ocean — is over. The world is reaching a tipping point: according to some estimates, by 2030 we will be extracting twice as many natural resources annually as the Earth can supply.1 This means we are using our planet’s resources twice as fast as they can be replenished.

Manufacturing must shift from a linear trajectory to a cycle that keeps materials and products that are still viable in circulation for as long as possible. By reusing, repurposing, recycling and remanufacturing both raw materials and manufactured products, companies can significantly reduce waste and advance sustainable outcomes.

The circular economy represents a leap forward in environmental and socially responsible practice, but it also introduces new complexities to supply chain management and oversight. How do we assess the remaining useful life of a product or material? How do we accurately and efficiently determine which items should be reused or repurposed and which should be recycled? What is the financial impact of each decision, and how does this evolving process change our calculations of economies of scale? In a circular supply chain, manufacturers must capture, analyze and factor in these and other new data points into management and oversight.

Sustainable Manufacturing and Supply Chains

Digitizing sustainability to achieve climate targets across the value chain

New digital capabilities offer organizations an unprecedented level of functionality for monitoring and managing sustainable supply chains. With a comprehensive, transparent platform, they can:

  • Gain insight around supply and demand so they can make more informed decisions, forecast more accurately and increase efficiency
  • Integrate AI and sensors into their processes to facilitate more intelligent and proactive operations
  • Use digital tools to improve traceability, creating an environment of mutual accountability with suppliers
  • Quantify the value of transitioning to a circular model with advanced reporting

How can organizations build this foundation and begin contributing to a circular economy? The answer begins with data, and companies like Hitachi are creating better ways to extract and analyze data which in turn can yield greater and more actionable insights.

Until now, identifying materials and tracking them through transactions across organizational boundaries has been difficult to impossible, with data often sitting in disparate or siloed systems - and in different data formats. Today, innovations such as digital contracts and distributed ledger technologies (blockchain) can help companies confidently track and trace transactions across the entire supply chain. Modern supply chain traceability solutions pull it all together by integrating, interpreting and analyzing the resulting data on an end-to-end, trusted digital platform.

Through recent experiences, we’ve learned that the supply chains of today face many risks: physical, economic, political and social. We believe the supply chain of the future will be illuminated by data that yields tangible, actionable insights, with the opportunity to be more sustainable, resilient and flexible. Greater transparency and visibility into how goods are sourced and manufactured around the world, whether locally, regionally or globally, will allow organizations to make better, faster decisions while reducing waste, improving efficiency and creating opportunities for innovation. This transformation of our supply chains will benefit all of us as we strive to reduce carbon emissions and create a more sustainable, equitable society.
