Carbon Intelligence is an AI-powered SaaS platform that calculates and optimizes CO₂ emissions across programmatic advertising supply chains. Using granular impression-level data from DSP log files, the platform applies emission factors based on device type, ad format, creative weight, data center energy mix, and network transmission to compute real-time carbon metrics per placement, domain, and campaign. Machine learning algorithms then identify low-carbon inventory opportunities and optimize bid strategies to reduce emissions by up to 70% while preserving KPIs (ROAS, CPA, viewability). The solution integrates with major DSPs via API or batch file processing, supports GARM/Ad Net Zero methodologies, and provides comprehensive carbon reporting dashboards for sustainability disclosure and regulatory compliance.
