Abstract

This study addresses the limitations of conventional incentive systems in encouraging sustainable behaviors -- such as donations, ethical consumption, and CO2 reduction -- by highlighting their lack of transparency, long-term viability, and respect for privacy. To overcome these issues, we propose a decentralized reward framework built upon a blockchain-based Self-Sovereign Information Environment (SSIE). Verified actions are recorded through NFTs and smart contracts, ensuring immutable traceability without disclosing personal information. Our system features a four-layered architecture: (1) sensing individual actions, (2) third-party measurement and MRV, (3) blockchain-based tokenization, and (4) value circulation via non-monetary or carbon-linked incentives. Field applications in Japan and India demonstrate real-world feasibility. In Japan, university students act as fundraisers linking elderly donors to underserved recipients, earning NFT-based social credits. In India, donations for girls- education are released via escrow only after blockchain-verifiable milestones are met. Environmental use cases include household energy-saving behaviors and coastal ecosystem restoration. Tokenized data enables accurate reporting of Scope 3 emissions while separately visualizing emission reduction, which, once verified, may serve as a reference for the basis for voluntary carbon market transactions. Unlike centralized models, our system ensures data provenance, supports multi-stakeholder engagement, and enables DAO-style coordination. Ultimately, this research presents a scalable, field-tested framework integrating behavioral science, privacy-preserving infrastructure, and decentralized governance. It offers practical tools for incentivizing sustainability, contributing to resilient social credit systems rooted in inclusion, autonomy, and trust.
