Role of Smart Contracts in Sustainable Supply Chains



Smart contracts have emerged as a revolutionary technological innovation with transformative implications across industries. But what are smart contracts and why do they matter, especially for Sustainable Supply Chain Management (SSCM)? 

What are smart contracts on blockchain?

Smart contracts are self-executing contracts where the terms are directly written into lines of code. These contracts operate on a blockchain, a decentralized and immutable ledger. This ensures that once the terms are set, they can’t be altered without the consent of all parties, providing a high level of security and transparency.

How smart contracts work

Smart contracts use “if-then” logic to execute contract terms automatically. For instance, if a good is delivered successfully, then a payment is released. This logic is coded into the blockchain and is executed without the need for intermediaries, making the process faster and more secure.

Why do smart contracts matter in SSCM?

Smart contracts have emerged as a revolutionary technological innovation with transformative implications across industries. Their application in Sustainable Supply Chain Management (SSCM) is particularly impactful.

Key benefits

  • Automating transactions

    Smart contracts automatically execute when predetermined conditions are met. This reduces manual oversight and accelerates transaction times, making supply chain processes more efficient.

    Ensuring accountability

    The immutability of blockchain technology, which often underpins smart contracts, ensures that once terms are set, they can’t be altered without the consent of all parties. This creates a system of accountability that can be invaluable in SSCM.

Application scenarios

  • Supply chain financing

    Smart contracts can automate the release of funds as goods pass through various checkpoints, ensuring that suppliers are paid promptly and transparently.

    Ethical labor practices

    Terms related to labor conditions, such as minimum wage or safety standards, can be programmed into a smart contract. Compliance can then be automatically verified through IoT sensors or manual data entry.

    Quality assurance

    Smart contracts can be used to enforce quality standards. For example, IoT devices can measure the temperature of perishable goods in transit. If the temperature exceeds predetermined limits, the smart contract can automatically notify all parties.

Risks and challenges

  • Legal implications

    While smart contracts offer a new layer of security and automation, they are still relatively new in the eyes of the law. Legal frameworks for dispute resolution in the context of smart contracts are still under development.


    While blockchain is inherently secure, smart contracts are only as secure as their code. Bugs or vulnerabilities could potentially be exploited, leading to undesired outcomes.

Smart contracts are an exciting frontier in SSCM

Smart contracts present an exciting frontier for innovations in Sustainable Supply Chain Management. They offer automation, transparency, and a high degree of accountability. However, like any technology, they are not without their challenges, particularly concerning legal recognition and security.

The adoption of smart contracts in SSCM is a growing trend that shows promise in making supply chains more sustainable, transparent, and efficient. As technological, legal, and security aspects continue to evolve, the role of smart contracts is expected to expand, offering even more robust solutions for complex supply chain challenges.

By embracing smart contracts, businesses can position themselves at the forefront of sustainability and technological innovation, meeting the needs of increasingly conscientious consumers and regulatory bodies alike.
