Virginia's Department of Environmental Quality (DEQ) has launched SWaN, a digital environmental credit market on the Hedera network. This platform facilitates real-time trading of stream, wetland, and nutrient credits across more than 600 sites, enhancing transparency and compliance with the state's 'no net loss' policy. SWaN provides on-chain data for live pricing and availability, unifying credit markets and ensuring approved sites remain in perpetual conservation. This initiative supports long-term on-chain analysis of environmental impact and market trends.
