Turning resource data into measurable sustainability impact
Sustainability is no longer measured only by internal commitments. Today, it is defined by real-world impact.
As global utilities face increasing pressure to conserve resources, improve efficiency and decarbonize operations, data is becoming one of the most powerful tool for sustainable development.
The 2025 Diehl Metering Sustainability & IMS Report shows how sustainable smart metering helps transform resource data into measurable environmental impact.
This report highlights the progress Diehl Metering has made in environmental, social, and governance (ESG) performance. It also shows how smart meters, connectivity, and digital solutions promote sustainable water and energy resource management, and long-term utility resilience.
How Diehl Metering enables sustainable resource management
Diehl Metering sustainability efforts increasingly focus on enabling positive outcomes for utilities through technology and data.
By combining meters, connectivity, software and analytics, Diehl Metering helps utilities across key areas:
Network performance:
- Detect anomalies and leaks earlier
- Improve network efficiency
- Strengthen service continuity
Resource efficiency and sustainability:
- Reduce water and energy losses
- Optimize water and energy consumption
- Support operational decarbonization
Data and decision making:
- Make better decisions through real-time data
This approach places sustainable resource management at the heart of the company's strategy and reinforces the role of smart metering sustainability in addressing global water and energy challenges.
Sustainable smart metering: turning data into action
Traditional metering provides consumption data. Intelligent metering creates actionable insights.
The report illustrates how sustainable smart metering supports utilities throughout the entire resource management journey:
- Measure
- Connect
- Manage
- Act
This approach enables utilities to move from simple measurement to active resource optimization.
Through intelligent water metering, remote reading capabilities, anomalies detection and advanced analytics, utilities gain better visibility of their networks and can take corrective action faster. Data-driven insights generated by smart utility solutions help improve operational efficiency while supporting environmental goals. As a result, sustainability becomes measurable, scalable and operational.
Advancing decarbonization through smart metering
At the same time, the company continues to strengthen its own climate commitments through its reduction of carbon emissions.
Diehl Metering remains committed to the Science Based Targets initiative (SBTi) and continues its journey toward net zero by 2050 through a structured climate action strategy and science-based emissions targets.
ESG performance and responsible business practices
The 2025 report also presents the company's latest achievements in ESG performance and governance.
Highlights include:
- Continued participation in the United Nations Global Compact through its annual Communication on Progress (COP) submissions
- EcoVadis recognition
- Expanded ISO certification coverage with ISO 50001
- Updated ESG indicators and reporting methodology
These achievements reinforce Diehl Metering's commitment to transparency, ethical business practices and continuous improvement.
The report reflects the company's broader corporate sustainability strategy, including sustainability governance, employee wellbeing, diversity and inclusion, and responsible business practices throughout the value chain.
Building sustainable metering solutions through circularity and ecodesign
The report demonstrates significant progress in sustainable product development.
Diehl Metering continues to integrate environmental considerations throughout the smart meter lifecycle, from design and manufacturing to end-of-life management.
Examples highlighted in the report include:
- Eco-designed ALTAIR V5 meters
- Improved recyclability
- Free-potting radio designs
- End of life products recycling initiatives
- Lifecycle-based environmental assessments
These efforts support a more circular approach to innovation and contribute to the development of sustainable metering solutions with reduced environmental impact.
Looking ahead
The future of sustainability depends on the ability to transform information into action.
As utilities continue to address water scarcity, resource efficiency, decarbonization, and infrastructure challenges, smart metering and digital technologies will play an increasingly important role. Through its solutions, expertise, and long-term commitments, Diehl Metering helps customers move from data collection to measurable impact. While ESG commitments, certifications and governance remain essential, the most important impact comes from enabling customers to manage resources more efficiently.
The 2025 Sustainability & Integrated Management System Report demonstrates how sustainable smart metering can support a more resilient and resource-efficient future.
Our responsibility is to turn experience into progress: helping utilities preserve essential resources, strengthening our own operations and moving forward together with the agility needed to build a more sustainable future.
