Inspiration

The Carbon Crisis in Indonesian SMEs

Indonesia is the world’s 8th largest carbon emitter, yet most Small and Medium Enterprises (SMEs) lack access to affordable and transparent carbon management tools. Through direct observation, we saw how Indonesian businesses struggle with:

  • High costs: Enterprise carbon tracking solutions cost $10,000–$50,000 per year, far beyond SME budgets
  • Lack of transparency: Traditional carbon tracking relies on opaque third-party auditors
  • No verifiable proof: Companies cannot credibly prove sustainability claims to stakeholders or regulators
  • Complex processes: Existing tools require technical expertise most SMEs do not have

We realized that three powerful technologies — Cloud, Climate AI, and Blockchain — could solve this problem if integrated correctly.

Thus, RANTAI 3C was born:
A blockchain-verified carbon management platform, purpose-built for the Indonesian market to make sustainability accessible, transparent, and affordable.

    • Carbon Capture

  • Flexible offset amounts
    Purchase from 0.01 to 1,000 tons CO₂

  • Dual payment system

    • 💰 Crypto payments: ETH via MetaMask (fully decentralized)
    • 💳 Fiat payments: PayPal for non-crypto users

  • Automatic NFT rewards
    Each offset purchase mints a blockchain-verified NFT certificate with instant notification

  • Net-zero tracking
    Visual progress toward carbon neutrality

  • Dynamic pricing
    $12–$25 per ton CO₂ with live Oracle updates
