ROI Calculation Logic

Implementing this technology could reduce costs associated with carbon taxes and emissions trading. For example, a company emitting 100,000 tons of CO2 annually could reduce emissions by 20% using this technology. Assuming a carbon credit price of ~$35/ton (AI est.), this would result in an estimated annual cost reduction of 100,000 tons × 20% × $35/ton = ~$700K (AI est.). Furthermore, easy integration into existing facilities could significantly reduce initial investment costs.
