The Challenge
A Singapore-based climate-tech startup approached Weiblocks with a mission to address the fundamental problems plaguing voluntary carbon markets: double-counting, fraud, lack of transparency, and limited accessibility. The voluntary carbon market faces systemic problems that undermine trust and adoption: Double Counting, Fraud & Greenwashing, and Lack of Transparency. The client needed a technical partner who understood both blockchain architecture and the complexities of carbon market compliance.
