Blockchain technology started with cryptocurrencies like Bitcoin. But today, it is moving far beyond that. Businesses now use it to track and build trust in data. This shift helps companies meet strict environmental rules and prove their green claims. In this post, we explain everything you need to know about this change.
Companies must report their carbon footprint. This includes direct emissions from their factories (Scope 1) and indirect ones from energy use (Scope 2). But the biggest part is Scope 3 emissions. These come from suppliers, shipping, and how customers use products.
Scope 3 often makes up 70% to 90% of a company’s total emissions. Yet, it is the hardest to measure. Why? Supply chains involve hundreds or thousands of partners. Data from different suppliers often conflicts. This leads to disputes and doubts about accuracy.
The World Economic Forum points out that just eight global supply chains create over 50% of all greenhouse gases worldwide. Think food, fashion, electronics, and more. Big companies face huge risks if they cannot verify this data. Regulators demand proof, and customers want transparency.
Blockchain is a digital ledger. It lets many parties add and view data. Once added, no one can change it without everyone noticing. This creates a “single source of truth.”
For , blockchain records data from every step. Sensors on trucks log fuel use. Factories report production emissions. All this goes on the chain, timestamped and unchangeable.
Key benefits:
Experts say the real power comes from good data input and wide use. If all suppliers join, it works great. Poor data or low adoption kills it.
Retail giants led the way. Walmart used blockchain to trace mangoes in the US. Before, it took nearly seven days. Now, it takes seconds. This cuts risks like recalls and proves fresh origins.
In shipping, Maersk tried TradeLens. It aimed to simplify global trade docs. But it shut down in 2022. Why? Not enough companies joined. This shows adoption is key.
Other wins:
Global spending on ESG reporting will top $15 billion a year. Blockchain saves time and money here.
Carbon credits let companies offset emissions by funding green projects. But fraud is common. Bad projects claim fake reductions.
Blockchain fixes this with linked sensors. Trees planted? Sensors prove growth. Credits issued only if real. This makes offsets verifiable, permanent, and additional.
Studies show many programs lack trust. Digitizing helps, but only if tied to real-world proof.
Smart firms turn blockchain into revenue. They build internal tools for emissions tracking. Then, sell access to others.
Tokenization is hot too. Digital tokens represent real goods or emissions rights. This lets fractional ownership and easy trading.
Permissioned blockchains rule enterprise use. Only approved users join. This adds security and fits business needs.
Blockchain is not magic. Wharton professor Kevin Werbach calls it a “new trust structure.” But it needs rules, dispute fixes, and accountability.
Main hurdles:
| Challenge | Solution |
|---|---|
| Low adoption | Incentives and standards |
| Data quality | IoT integration and AI checks |
| Cost | Cloud-based platforms |
| Regulation | Work with governments |
Success depends on long-term funding and commitment. Past pilots failed without it.
Expect more integration. Blockchain with AI predicts emissions. With IoT, it auto-logs data. Standards like GS1 will help chains connect.
Regulations push this. US SEC and EU rules demand better tracking. Companies ignoring it risk fines.
By 2030, blockchain could handle most enterprise supply chains. It shifts from crypto hype to real tools for and sustainability.
Blockchain proves its worth beyond crypto. It tackles the tough Scope 3 problem, builds trust, and cuts costs. Early adopters win big. Will your company join?
Start small: Pilot one supply chain. Partner with experts. The future is transparent and green.
