Sustainable Technology

What is sustainable technology?

Sustainable technology encompasses solutions that help reduce the environmental impact of IT infrastructure across its entire lifecycle.

What constitutes sustainable IT?

Sustainable IT refers to the practice of using information technology in a way that minimizes its environmental impact and maximizes its long-term sustainability. It involves a combination of strategies and practices aimed at reducing energy consumption, minimizing waste, and promoting environmentally responsible decision-making within the IT industry.  It is also a set of manufacturing, management, use and disposal practices that attempt to lower the environmental impact of the solutions and industry. 

  • Sustainable IT manufacturing involves a wide array of strategies and initiatives focused on enhancing the development of innovative approaches with reduced environmental impact. 
  • Sustainable IT management concentrates on optimizing the operational or use phase of the IT lifecycle. This entails efficient asset management by organizations, the adoption of energy-efficient equipment, and the exploration of renewable energy sources.
  • Sustainable IT disposal seeks to optimize the end-of-life stages, giving particular attention to the principles of the circular economy. Sustainable IT is an essential component of broader environmental sustainability and responsibility initiatives within organizations. By adopting these practices and principles, businesses and individuals can reduce their carbon footprint, minimize resource consumption, and contribute to a more sustainable IT industry.

IT for sustainability

This concept is broader and focuses on using information technology as a tool to promote overall sustainability within an organization or society. It includes leveraging IT solutions to reduce carbon footprints, such as through smart energy management systems, supporting remote work to reduce transportation-related emissions, or developing systems for efficient resource management in various industries. IT for sustainability is more about the application of IT in pursuit of broader environmental sustainability goals than the environmental impact of the IT sector itself.

While Sustainable IT is about making the IT sector more environmentally sustainable, IT for sustainability is about using IT as a tool to achieve broader environmental sustainability goals. HPE has a rich portfolio of products and services for Sustainable IT.

How is environmental impact reduced across the technology lifecycle?

  • The upstream phase considers the environmental impact of all activities from concept design through delivery to the customer. Activities that aim to reduce the upstream impact include reducing the amount of waste created as well as energy and water used from manufacturing to distribution logistics that minimize emissions. 
  • The use phase includes the environmental impact associated with the use of IT products. Considerations include focusing on identifying opportunities for efficiencies at the IT hardware and software levels followed by efficiencies in mechanical and electrical infrastructure around the IT hardware. Key focus areas include energy efficiency, equipment efficiency, resource efficiency, software efficiency, and data efficiency.
  • The end-of-use phase includes the environmental impact of IT assets once the useful life of the product ends. Considerations in this phase include a product's repairability and recyclability as well as services to advance the circularity of the assets.
