This article examines how Totogi's cloud-native Charging-as-a-Service platform on AWS reduces carbon emissions for mobile network operators compared to traditional charging systems.

• Mobile industry generates ~490 million tonnes CO2e annually; operators committed to 2030/2050 emissions targets
• Totogi's multi-tenant SaaS platform reduces total cost of ownership by over 50% versus on-premises deployment
• Traditional charging systems require ~25 servers minimum; Totogi shares infrastructure across hundreds of telcos
• AWS infrastructure is 3.6-5x more energy efficient than enterprise data centers; can reduce workload carbon by up to 96%
• Totogi achieves 73% CPU utilization versus 6-25% average in on-premises data centers through auto-scaling
• Uses AWS Graviton2 processors for 2-3.5x better CPU performance per watt than other AWS processors
• Implements data compression, scheduled background jobs, and renewable energy-powered AWS regions

Totogi demonstrates how cloud-native architecture and AWS deployment significantly reduce telecommunications infrastructure carbon footprint while improving operational efficiency and scalability.
