The tech industry accounts for over 7% of global emissions. This number is expected to rise rapidly in 2025 with the continued growth of data centres, cloud computing, and further widespread use of electronic devices.
This continued rise in e-waste and high energy usage is the main driver behind the increased push for a more sustainable approach to IT. But the reality of implementing more sustainable IT practices is not without its challenges, including:
- What to do with outdated equipment
- Costs of replacing hardware and software
- Lack of awareness and support internally
- Restricted resources and time
- Difficulty measuring impact
In this article, we look at the solution to these challenges – Sustainable IT – and its benefits for both the environment and your business.
What is Sustainable IT?
Also known as Green IT or Green Computing, Sustainable IT is the practice of using information technology in a way that minimises environmental impact while maximising business value. This means adopting strategies and technologies that reduce energy consumption, waste, and greenhouse gas emissions throughout the entire IT lifecycle, such as:
- Energy-efficient hardware and infrastructure
- Waste reduction and e-waste management
- Renewable energy sources
- Software and data optimisation
- Employee awareness and education
Business benefits of Sustainable IT
Adopting Sustainable IT practices is a win-win proposition for businesses of all sizes. By adopting sustainable practices, your business can not only help protect the environment but also improve your bottom line and enhance your reputation, among other benefits:
- Reduced operational costs: By using only energy-efficient hardware, software, and data centres, you can significantly lower your energy bill
- Enhanced brand reputation and customer loyalty: Customers are increasingly concerned about environmental issues, and businesses that demonstrate a commitment to sustainability can attract and retain customers, especially large corporations and public sector organisations
- Increased employee engagement: Employees are more likely to be engaged and motivated when they work for a company that is committed to sustainability
- Competitive advantage: In an increasingly competitive market, sustainability can be a key differentiator for your business
- Improved risk management: By reducing your reliance on fossil fuels and other finite resources, your business can mitigate risks associated with supply chain disruptions and price volatility
- Compliance with regulations: Many governments, the UK included, are implementing regulations to promote sustainability, and businesses that adopt Sustainable IT practices can avoid costly fines and penalties. For example, SECR is a UK regulatory requirement that mandates certain businesses to report their energy use and carbon emissions, along with related actions
Let’s explore some Sustainable IT strategies and technologies you can implement in your business:
Energy efficiency
Ensuring your business’s technology is as energy-efficient as possible is the first step in implementing Sustainable IT and reaping its benefits.
Here’s where to focus your efforts:
- Energy Star-certified devices: Choose devices (computers, servers, printers) with Energy Star certification, which ensures they meet strict energy efficiency standards
- Virtualisation: Consolidate multiple virtual machines onto a single physical server, reducing the number of servers needed and associated energy consumption
- Cloud computing: Utilise cloud services that leverage highly efficient data centres with optimised cooling and power management
Efficient data centres will implement optimisation strategies like these:
- Air cooling: Efficient data centres utilise efficient air cooling systems to minimise energy consumption
- Free air cooling: Efficient data centres take advantage of natural cooling whenever possible
- Virtualisation and consolidation: Efficient data centres consolidate servers and virtualise workloads to reduce the number of physical servers required
E-waste management
E-waste, the rapidly growing mountain of discarded electronics, is a significant environmental concern worldwide, estimated at 57.4 million metric tonnes.
Refurbishment and reuse
Refurbish and reuse old equipment whenever possible, extending its lifespan and reducing e-waste.
Case study – SensationALL
Over the past decade, we have donated computers, laptops, servers, and networking equipment to various charities and non-profit organisations, enabling them to utilise much-needed IT equipment in their offices and workplaces.
For example, in June 2024, we donated refurbished computing equipment to SensationALL, a charitable organisation that provides therapy-based activities and specialist support for children and adults with additional support needs and disabilities.
“As a self-funded charity, we rely solely on donations of IT equipment for our offices and staff, as a budget for new office tech simply does not exist. Some members of the team are still using equipment donated over 10 years ago! ”
Katie McNutt – CEO, SensationALL
From our experience helping SensationALL and other charitable organisations over the years, we have some recommendations when donating equipment for reuse:
- ensure the donated equipment is in good working order and relatively modern
- get permission from the previous owner, informing them it will be donated
- ensure all equipment is thoroughly erased and meets security and operational standards
These steps will guarantee that the recipients receive reliable and safe devices, ready for immediate use.
Proper disposal
Responsible e-waste disposal means partnering with certified e-waste recyclers to ensure proper disposal of electronic equipment.
E-waste contains valuable materials like metals (gold, copper) but also hazardous substances like lead, mercury, and cadmium. Improper disposal can lead to:
- Soil and water contamination
- Air pollution from burning e-waste
- Release of harmful chemicals into the environment
Extended product lifecycles
Purchase durable hardware with longer lifespans to reduce the frequency of replacements. This will ensure that the hardware will meet your demands not only in the short term but also in the future.
You can also extend the lifespan of the electronic devices used by your business through proper maintenance and repair.
Virtualisation and Cloud Computing
Virtualisation and cloud computing have emerged as powerful tools in the pursuit of Sustainable IT. By optimising resource utilisation and reducing the need for physical hardware, these technologies significantly contribute to a greener IT landscape.
Virtualisation
Virtualisation allows multiple virtual machines (VMs) to run concurrently on a single physical server. This consolidation minimises the number of physical servers required, leading to:
- Reduced energy consumption: Fewer servers means lower energy demands for powering and cooling equipment
- Space savings: Less physical hardware means less space is needed for server rooms, potentially reducing the need for additional real estate
- E-waste reduction: Fewer servers to purchase, maintain, and eventually dispose of means less electronic waste generated
Cloud Computing
Cloud computing takes virtualisation a step further by providing on-demand access to computing resources over the internet. This model offers several advantages for Sustainable IT:
- Shared Infrastructure: Cloud providers operate large, energy-efficient data centres that leverage economies of scale. By utilising these shared resources, businesses can avoid the energy overhead of maintaining their own on-premises infrastructure.
- Scalability and elasticity: Cloud services can be scaled up or down as needed, ensuring that resources are only used when required. This dynamic allocation prevents overprovisioning and minimises energy waste
- Renewable energy utilisation: Many cloud providers are increasingly utilising renewable energy sources to power their data centres, further reducing their carbon footprint
Practical tips for Sustainable IT
- Conduct an energy audit: Assess your current IT energy consumption and identify areas for improvement
- Implement a Sustainable IT policy: Develop a clear policy that outlines your company’s commitment to sustainable IT practices
- Engage employees: Educate employees about the importance of sustainable IT and encourage their participation in energy-saving initiatives
- Partner with sustainable suppliers: Choose suppliers who prioritise sustainability in their own operations
- Explore government incentives: Research and utilise available government incentives and funding programmes to support sustainable IT initiatives
