Sustainable IT surges: UK tech leaders make ESG a business imperative

Following this year's COP30 in Brazil, sustainability must shift from being an afterthought, to a key focus of business strategy for global enterprise leaders. For technology leaders in the UK, environmental, social and governance principles are no longer optional - they are shaping decisions that define competitiveness and resilience. Expereo's recent Enterprise Horizons research highlights this transformation and reveals how deeply sustainability practices are currently influencing technology priorities.

ESG as a performance driver

The findings show that sustainability is now viewed as a driver of performance rather than a compliance obligation. More than half (51%) of UK businesses believe that improving environmental metrics will enhance customer satisfaction, while nearly half (45%) highlight operational efficiency gains and more than a third (35%) expect a stronger competitive position if these positions are adopted. 

These numbers reflect a growing understanding that ESG commitments resonate with customers, investors and employees alike. Organisations that fail to integrate sustainability into their technology strategies risk falling behind in a marketplace where accountability and transparency are becoming non-negotiables.

Networks and infrastructure under scrutiny

The findings also highlight the importance of networking and connectivity for sustainable IT. Almost half of UK businesses (48%) identify these areas as essential for reducing environmental impact. This emphasis makes sense when considering connectivity underpins every aspect of digital operations, from cloud migration to remote work. Optimising network infrastructure for energy efficiency can deliver significant reductions in carbon emissions, particularly when combined with intelligent traffic management and bandwidth optimisation. Cloud platforms and AI-driven data solutions follow closely on the priority list, highlighting the need for scalable technologies that minimise energy consumption while supporting agility.

Procurement practices reflect new priorities

The sustainability agenda is also reshaping procurement practices amongst global enterprises. Two-thirds (67%) of UK businesses now require formal sustainability credentials from their technology partners, whilst 18% demand major accreditations. This shift signals a new era of vendor accountability. Cost and technical capability remain important, but they are no longer sufficient. Enterprises are asking whether partners have credible sustainability roadmaps, whether they follow recognised standards, and whether they provide transparent reporting on emissions and energy use. These questions are becoming standard in procurement processes and technology providers that cannot meet these expectations risk missing out on critical projects.

Investment outlook signals long-term commitment

Looking ahead, the investment outlook reinforces the permanence of this trend. One in five UK businesses plan to prioritise solutions that reduce energy consumption and carbon emissions over the next year. This commitment is driving interest in technologies such as green data centres, edge computing and AI-powered energy optimisation. These innovations not only support environmental goals but also deliver tangible business benefits, including cost savings and improved performance. For technology leaders, the challenge lies in identifying which investments will deliver the greatest sustainability return while enabling digital transformation.

Building a sustainability strategy

Embedding sustainability into technology strategy requires more than isolated initiatives. It demands a holistic approach that aligns infrastructure, connectivity and operational models with environmental objectives. This begins with a clear understanding of current energy consumption and emissions across IT systems, followed by actions to modernise networks and migrate workloads to providers with strong sustainability credentials. It also involves integrating sustainability criteria into vendor selection and establishing concise reporting frameworks to track progress and build trust with stakeholders.

The bigger business imperative

The implications extend beyond technology - sustainability is becoming a channel for organisations to evaluate growth opportunities, innovation pathways and risk management strategies. It influences how businesses position themselves in the market and how they engage with customers and partners. For technology leaders, this means adopting a mindset that views ESG not as a constraint, but as a catalyst for resilience and long-term success.

A defining moment for technology leaders

The merging of sustainability and technology strategy is reshaping the competitive landscape quicker than ever before. Organisations that act decisively will not only meet regulatory and societal expectations but also unlock new avenues for innovation and growth. Those that hesitate risk being left behind in a world where environmental stewardship is synonymous with business leadership.
