1. Mainframes Are Already More Efficient Than x86

IBM notes that “energy consumption could triple” if a European bank moved from IBM Z to x86 infrastructure.

CPS Connection:
CPS enhances this inherent mainframe efficiency even further. By tuning VSAM and DB2 workloads, CPS reduces CPU usage—amplifying the existing energy and carbon advantages of staying on IBM Z.

2. Reducing CPU Usage = Carbon Reduction

The IBM IT Economics team estimated that replacing 47 x86 blades with LinuxONE reduced CO₂ by 946 metric tons over five years.

CPS Connection:
TurboTune and TTSQL reduce CPU cycles and I/O calls. This lowers energy demand per workload—just like in IBM’s LinuxONE example—but without hardware migration. CPS achieves carbon and cost reductions within your current system.

3. Energy Efficiency Drives Compliance and Competitive Advantage

“Compliance with environmental directives is required to avoid financial penalties… contribution to sustainability is also a competitive advantage.”

CPS Connection:
CPS delivers quantifiable Scope 2 and Scope 3 reductions, which customers can report in ESG disclosures. This positions mainframe clients ahead of regulatory and investor expectations—without needing to “modernize” off-platform.

4. Modernizing on Z Reduces Energy Use

IBM shows that upgrading from z13 to z15 cut energy use by 51%.

CPS Connection:
CPS can be deployed alongside (or in place of) hardware upgrades to capture additional savings. For clients not ready to refresh hardware, CPS provides a software-based optimization path to similar sustainability benefits.

5. Data Centers Must Do More with Less

“High compute and storage density” and “system architectures that enable high resource utilization” are recommended best practices.

CPS Connection:
That’s exactly what CPS helps mainframes do: run smarter, cleaner, and leaner. We improve resource utilization and throughput per watt—aligning directly with IBM’s recommendations for sustainable data centers.
