The Urgency of Sustainability

Data centres play a crucial role in modern infrastructure, but their environmental impact is significant. At Keysource, we understand the urgency of data centre sustainability in the face of increasing energy consumption and operational costs.

Our sustainability services provide customers with legislative and regulation advice to help navigate a changing landscape, audits, assessments, embodied & operational carbon modelling to measure and benchmark performance, intervention assessments to identify feasible opportunities, and renewable solution analysis for robust technical and commercial business cases to delivery sustainability goals and objectives.

Why Do You Need Sustainability Services?

Increasing energy consumption and operational costs

A study by the McKinsey Global Institute estimates that data centre energy consumption could grow by 50% from 2020 to 2030.

These trends contribute to rising electricity costs, impacting data centre operational budgets.

Pressure to reduce carbon footprint and MEET green goals

Consumers and investors are increasingly demanding greater environmental responsibility from businesses.

Regulatory bodies are implementing stricter environmental regulations, including carbon emission reduction targets

Regulatory requirements and compliance complexities

Data centres are being subject to more and more environmental regulations, such as energy efficiency standards and emission limits.

These regulations can be complex and change frequently, requiring data centre operators to stay up-to-date and ensure compliance

Our Services

In 2019, the UK became the first major economy in the world to set a binding target to reach net zero emissions by 2050. More than 90% of global gross domestic product and 88% of global emissions are now covered by net zero commitments. We can help you reach your net zero target, no matter where you are on your journey so far. Our main services include:

Decarbonisation Assessment

Our decarbonisation assessment services focus on optimising energy consumption to reduce carbon emissions across Scope 1, Scope 2, and Scope 3 categories. We evaluate current energy usage patterns, infrastructure efficiency, and potential areas for improvement to develop tailored strategies that align with sustainability goals.

This holistic approach not only enhances operational efficiency and lowers long-term operational costs but also addresses the increasing importance of carbon emissions in today's business environment, where stakeholders and customers prioritise environmental responsibility and sustainability initiatives. Our comprehensive approach not only helps data centres meet regulatory requirements and industry standards but also strengthens their reputation as responsible organisations committed to environmental sustainability.

Clean Energy Sourcing

Our clean energy sourcing strategy is designed to empower data centre clients with sustainable energy solutions tailored to their specific needs. Data centres can transition away from fossil fuels, significantly reducing their carbon footprint and aligning with global sustainability goals.

Our team of experts conducts thorough assessments to identify the most suitable clean energy sources from wind, solar, and hydroelectric power, based on location, energy demand, and budget considerations. Whether you're aiming to achieve carbon neutrality or enhance your green credentials, we can provide customised strategies that prioritise efficiency and cost-effectiveness. Our approach prioritises the design and implementation of systems that generate electricity on-site rather than relying on purchasing renewable energy off-site.

Green Building Certifications


BREEAM is used to specify and measure the sustainability performance of buildings. The framework enables reduced life cycle costs and increases in asset value, building user experience and health, corporate image and CSR requirements, and risk mitigation.


NABERS Energy ratings measure and verify the actual energy use of existing buildings, providing a rating from 1-6 stars and helping building owners to accurately target, measure and communicate the energy performance of their buildings. This investment grade rating can be used to demonstrate whether you are on a net zero carbon trajectory.


LEED is the world’s most widely used green building rating system. The certification provides a framework for healthy, highly efficient, and cost-saving green buildings, which offer environmental, social and governance benefits.

Maria has considerable experience in the building industry and has been involved in all aspects related to sustainability and low-carbon design, and can provide input for complex projects.

A recent example of her achievements is the proposed refurbishment and extension of 4-5 Paris Garden and 18-19 Hatfields to create a single use office building, located in the London Borough of Southwark: An extensive feasibility study evaluated a range of low and zero carbon technologies for their potential to reduce CO2 emissions of the development. The study concluded that Air Source Heat Pumps (ASHP) and Photovoltaic Panels (PVs) are the most effective technologies, offering significant carbon reduction benefits:

  • ASHPs could achieve a 33.7% reduction in carbon emissions.
  • 90m² of Photovoltaic Panels on the roof could result in a 1.9% reduction in carbon emissions.
