Hitachi Vantara, the data storage and hybrid cloud subsidiary of Hitachi Ltd, published its FY2025 Sustainability Report on Thursday, outlining measurable energy and cost reductions achieved by clients using its latest sustainable data infrastructure platforms, as surging AI workloads reshape the economics of enterprise computing.

The report arrives as the International Energy Agency warns that global data center electricity consumption could surpass 1,000 terawatt-hours by 2026 — roughly equivalent to a major industrialized nation’s annual usage — driven in large part by artificial intelligence workloads that demand constant, high-performance storage and processing.

“Sustainability is increasingly tied to operational performance and business outcomes. In FY2025, we focused on helping customers manage the growth of AI and data while improving efficiency and reducing environmental impact,” said Akinobu Shimada, CEO, Hitachi Vantara in a statement.

Among the report’s most striking findings: Turkish retail bank DestekBank achieved a 25% reduction in data center energy consumption after deploying Hitachi Vantara’s VSP One Block platform, alongside a 35% jump in application performance and a 20% drop in total cost of ownership. Belgian water utility Aquiris, which processes more than 110 million cubic meters of wastewater annually, credited the same platform with lowering its carbon footprint while collecting over one million data points per day for process monitoring.

Indian media company Malayala Manorama reported the sharpest operational gains, cutting data center rack space by 66% and achieving 70% savings in power and cooling costs after modernising its infrastructure to support round-the-clock print, broadcast and digital operations.

On the product side, the company introduced the VSP One Block High End, engineered to reduce power and cooling requirements for enterprise and AI-driven workloads. Hitachi Vantara also expanded lifecycle assessments across its VSP One Block, File and Object portfolios and launched its Clear Sight dashboard, giving customers direct visibility into energy consumption and carbon usage. The firm reported that up to 50% recycled content now appears in key components, and that less than 0.3% of materials were sent to landfill.

Governance improvements included strengthened emissions tracking across Scope 1, Scope 2 and key Scope 3 categories, aligned with science-based reduction targets and evolving ESG reporting standards.
