How Blockchain is Reshaping Sustainable Supply Chains

Manufacturing is approaching an age when sustainability is no longer optional; it is a competitive requirement. Supply chains span multiple countries, employ hundreds of people, and provide extensive information on where products originate, the energy they consume, and the waste they generate. In this complex world, it can be challenging to verify whether sustainable practices are being implemented and to hold individuals accountable. Blockchain is now becoming an essential tool for addressing these problems. It offers traceability, transparency, and productivity that fit with global sustainability objectives.

One of the most critical issues in sustainable manufacturing is that the process is not entirely transparent. Standard reporting methods are often fragmented, making it easy to make mistakes and correct them.

Blockchain solves this problem by using a shared ledger that can’t be changed and keeps track of every transaction, from getting raw materials to delivering the finished product.

This openness lets manufacturers back up their claims about being environmentally friendly. Without relying on incomplete or unverifiable documents, consumers can verify that raw materials are sourced ethically, investors can assess the company’s environmental performance, and regulators can ensure the company is adhering to regulations. Institutions such as the World Economic Forum have previously stated that supply-chain traceability is one of the key benefits of blockchain in supporting environmental sustainability.

Blockchain is already demonstrating promise in several fields. For example, Walmart worked with IBM to test blockchain in food safety. The findings were striking: it took over a week using conventional methods to determine the origin of sliced mangoes, but it only took 2.2 seconds to verify on a blockchain ledger. Walmart built on that success by expanding the initiative to all of its leafy greens supply chain, requiring suppliers to be able to track their products throughout the supply chain.

Volvo Cars has also previously collaborated with the technology company Circulor to utilize blockchain technology to track the movement of cobalt from the mine to the batteries in electric cars.

Another well-known case is the diamond industry. De Beers’ Tracr technology utilizes blockchain to track millions of diamonds, providing provenance. A similar technique, of confirmed origin, could be applied to metals, textiles, and other items throughout various supply chains.

Increasingly, sustainable production requires circularity, which entails creating items that can be reused, repaired, or recycled rather than being discarded. Blockchain is a good fit for these models because it can accurately track product histories that are durable and reliable.

Blockchain does more than just hold data. When used with smart contracts, it can also trigger actions automatically. Payments may only be made when certain sustainability conditions are met, such as when a supplier achieves its emissions objectives. By identifying precisely which batches are affected, you can make recall operations more efficient and reduce waste. IoT sensors that work with blockchain may provide real-time information on energy usage, emissions, or water use. This makes sustainability reporting a living, verifiable process, rather than a historical event.

These rules and standards-based projects will make blockchain-enabled traceability not just a unique feature, but also a must-have.

Conclusion

Blockchain isn’t a magic bullet, but it can help make manufacturing more sustainable. Blockchain makes sustainability more than just a promise by making supply chains transparent and ensuring compliance is easily verifiable. As deadlines for regulations draw closer and industry standards improve, firms that invest in blockchain-based traceability today will be in the best position to succeed in the future low-carbon economy.
