How Blockchain Technology Can Support Sustainability Efforts

Blockchain technology has emerged in recent years as having major potential to support sustainability efforts around the world. With its decentralized, transparent, and secure structure, blockchain offers innovative solutions to many sustainability challenges.

In this comprehensive article, we will explore the key features of blockchain and how they can promote environmental, social, and economic sustainability.

How Blockchain Technology Works

Before examining the specific applications, it is helpful to understand what blockchain is and its core components.

Blockchain is a distributed ledger system that records transactions or data in a way that is permanent and unchangeable. Transactions are recorded in “blocks” that are linked cryptographically together in a “chain.” This creates an immutable, shared record across a decentralized network of computers rather than a single centralized server.

Some key features that enable blockchain to support sustainability:

• Decentralization – No single authority controls the network. Transactions are verified through consensus across the network. This promotes transparency and democratization.
• Provenance – Detailed histories of transactions are recorded on the blockchain ledger. This enables tracing the origins and lifecycle of products or services.
• Immutability – Records cannot be altered retroactively. This lends credibility and accountability to sustainability efforts.
• Security – Cryptography and distributed consensus make blockchain highly resistant to unauthorized changes or hacking.
• Smart contracts – Programmed contracts automatically execute when conditions are met. This automation streamlines sustainable supply chains.

Let’s explore some of the major sustainability benefits that arise from these blockchain features.

Environmental Sustainability

Blockchain is well suited to enhancing environmental sustainability in areas like emissions tracking, renewable energy, sustainable supply chains, and climate finance.

Emissions Tracking

By providing tamper-proof, transparent tracking of greenhouse gas (GHG) emissions, blockchain could play a significant role in monitoring and verifying compliance with climate goals. This is particularly valuable for cap-and-trade programs or carbon taxes that aim to limit emissions.

For example, IBM and Energy Blockchain Lab have partnered on a blockchain pilot to track carbon credits for renewables, allowing creators and buyers to seamlessly trade credits while ensuring credibility and avoiding double-counting.

Renewable Energy

Blockchain enables decentralized tracking of renewable energy generation and distribution. This facilitates wider adoption of clean power sources through peer-to-peer trading of solar or wind energy.

Startups like Power Ledger allow homeowners with rooftop solar panels to sell excess energy to neighbors, enabled by blockchain’s immutable and transparent transaction records. This blockchain-based transactive energy model promotes decentralized renewable generation.

Sustainable Supply Chains

Global supply chains often lack transparency regarding the sources of raw materials and environmental impacts of production and distribution. Blockchain offers end-to-end traceability of supply chain data to verify sustainability claims.

For example, WWF uses blockchain to track tuna caught in the Pacific, monitoring it from net to plate. This helps verify responsible fishing practices that are crucial for protecting vulnerable tuna populations.

Climate Finance

Mobilizing finance for climate action relies on trusted systems to track funds allocation and verify results. As a tamper-proof ledger, blockchain provides accountability in climate finance programs.

The Climate Chain Coalition promotes blockchain to improve transparency, integrity, and access to climate financing. Pilot projects track green bonds, carbon credits, and funds distribution for clean energy – ensuring money flows to intended climate actions.

Social Sustainability

In addition to environmental benefits, blockchain features can also promote social sustainability in a variety of settings:

Supply Chain Ethics

Blockchain enables tracing the origins of materials not just for environmental sustainability but also social ethics. For industries like clothing, coffee, or minerals, blockchain can verify fair trade or fair labor practices.

Provenance uses blockchain to trace supply chains and provide immutable histories of products. Retailers can validate claims around ethical production and empower consumer choices.

Digital Identities

Lacking verified identity documents can exclude many people worldwide from vital social services. Blockchain offers secure digital identities that could expand financial, healthcare, and social service access.

For example, the UN’s World Food Programme uses blockchain to deliver cash assistance to refugees, securely recording beneficiaries and transactions on an immutable ledger.

Social Transparency

Charities, NGOs, and public programs can build trust by showing blockchain-verified details on how donations or funds are used. This transparency strengthens public sector accountability and philanthropic giving.

TrustLab develops blockchain tools for charities and governments to showcase verified impacts of donations and budget allocations. This engenders social sustainability by combating misuse of funds.

Economic Sustainability

In addition to environmental and social domains, blockchain technology offers multiple pathways to promote economic sustainability:

Responsible Sourcing

By tracing supply chain provenance, blockchain provides assurances of responsibly sourced materials. This unlocks sustainability-based value for producers of ethically sourced goods.

For example, Farmer Connect uses blockchain to track sustainably grown coffee “from bean to cup.” This verification allows farmers to capture greater value by selling certified sustainable coffee.

New Markets

Blockchain enables decentralized marketplaces for trading renewable energy credits, carbon offsets, sustainable commodities, and other environmental assets. This expands markets to catalyze sustainability financing.

Nori built a blockchain platform where companies can purchase carbon removal credits generated by farmers adopting regenerative practices. This unlocks new revenue streams to incentivize sustainable farming.

Cost Savings

By streamlining operations and automating processes, blockchain can reduce costs for businesses across sectors. These efficiency gains allow more investment in sustainability initiatives.

For instance, blockchain-based supply chain monitoring can reduce product losses, quality issues, and manual auditing expenses. Companies can reinvest these savings in sustainability upgrades.

Circular Economies

Blockchain supports circular economic systems focused on resource efficiency, waste reduction, recycling, and product life extension. Its supply chain transparency enables effective circular models.

Startups like Circularise offer blockchain tools to track materials usage and recovery. Manufacturers can optimize reuse and remanufacturing to minimize waste.
