Sustainable Infrastructure: Building Resilient, Low-Carbon Projects

euNetworks sets new sustainability loan targets

euNetworks, a European bandwidth infrastructure company, has introduced two environmental performance targets through its Sustainability-Linked Loan (SLL), linking sustainability measures to the design and development of new network infrastructure. The revised framework introduces Network Development Impact by Design Plans for major network projects, alongside a target for continuous improvement in the company’s GRESB infrastructure benchmark score. euNetworks first established its €760 million (£650 million) SLL in 2021 to support the expansion of its fibre network across Europe. The facility was then refinanced and expanded to €1.26 billion (£1 billion) in 2024. The Impact by Design Plans will now apply to major projects requiring significant new network construction. These projects account for a large proportion of euNetworks’ annual capital investment and approximately two thirds of its current greenhouse gas emissions. The plans will assess lower-carbon materials, construction techniques, and supplier options during the design stage, before project specifications are finalised. The approach is intended to incorporate environmental considerations into commercial and engineering decisions alongside cost, delivery times, and customer requirements. New targets added to €1.26bn loan The GRESB target will measure continuous improvement against an infrastructure-focused benchmark covering governance, environmental management, and operational performance. Marisa Trisolino, CEO of euNetworks, says, “Our new SLL targets mark an important step in euNetworks’ commitment to growing our business sustainably, focusing our efforts on the areas where we can deliver the greatest impact. “The introduction of our NetDev Impact by Design Plans represents a significant evolution in how we approach major network development projects, embedding sustainability considerations from the very beginning of the design and planning process.” The targets complement euNetworks’ existing sustainability commitments, including its validated Science Based Targets, net zero by 2040 commitment, supplier engagement programme, and carbon measurement tools.

Rubicon surpasses 1GW battery storage milestone

Rubicon Professional Services (RPS), a US design and construction firm for critical facilities, says it has surpassed 1GW of installed battery energy storage capacity across projects in the United States, as demand for data centre power infrastructure grows alongside AI. The company says the capacity is distributed across projects supporting data centres, telecommunications networks, healthcare facilities, manufacturers, educational institutions, housing developments, retail operations, and utilities. Battery energy storage can provide additional power resilience, help manage electricity costs, and reduce demand on the electrical grid during periods of peak consumption. For data centres and other critical facilities, storage can also support continuity of power during disruptions. RPS says the 1GW milestone represents battery storage capacity comparable with the output of a large utility-scale power plant. William Pirrone, Founding Principal at RPS, comments, "Surpassing one gigawatt of installed battery energy storage capacity represents more than a company milestone; it reflects years of helping customers solve increasingly complex power challenges. "Today, and into the foreseeable future, the rapid growth of AI compute will place unprecedented demand on our nation's electrical grid. Organisations need experienced partners who can deliver resilient, scalable power alternatives, efficiently and on schedule." Battery storage for rising power demand The company says its battery energy storage projects are being deployed across a range of sectors as electricity demand increases. RPS has worked on energy infrastructure projects across the US since 2019, including projects supporting data centres and other critical facilities. The company has 20 years of experience delivering electrical infrastructure projects and says around 95% of its business comes from repeat customers. It also says the growth of AI computing is increasing demand for electrical infrastructure and is contributing to greater interest in battery energy storage as part of power planning for data centres. The 1GW milestone covers installed battery energy storage capacity across RPS projects nationwide.

atNorth to power Danish food production with surplus heat

atNorth, a Nordic high-density data centre provider, is partnering with investment firm Selected Group to reuse surplus heat from its DEN02 data centre campus in Ølgod, Denmark, to support a large-scale greenhouse development. The project will use heat generated by the data centre to support local food production, with the first phase of the greenhouse development expected to be completed in Q3 2028. The development will be located on land adjacent to the DEN02 site and is intended to support year-round production of fresh fruit and vegetables in Denmark. Most fresh fruit and vegetables sold in Denmark are currently imported, particularly during winter when domestic production is limited by the climate. The project is intended to reduce reliance on imported produce and support a more resilient local food supply. The partnership forms part of atNorth's approach to incorporating heat reuse into data centre developments, connecting digital infrastructure with local agriculture. Surplus heat to support local production The first phase of the greenhouse development intends to use surplus heat from DEN02 to reduce the carbon emissions associated with conventional fossil-fuelled greenhouse heating. The project is also expected to create jobs during construction and ongoing operations, whilst providing additional economic activity in the Ølgod area. The greenhouse development is designed to expand alongside the DEN02 campus, creating an integrated site combining data centre infrastructure with agricultural production. Eyjólfur Magnús Kristinsson, CEO at atNorth, says, “This partnership demonstrates exactly what responsible digital infrastructure should look like. "By collaborating with forward-thinking organisations like Selected Group, we can transform surplus heat into a valuable resource that supports local food production, reduces carbon emissions, and strengthens community resilience. DEN02 is designed to integrate into Ølgod's community, and this project exemplifies this.” Peter Nielsen, CEO of Selected Group, adds, “Every unit of surplus heat should create value. By partnering with atNorth to convert surplus heat into local food production, we are demonstrating how digital infrastructure can strengthen food security while reducing emissions. "Reducing dependence on imported produce strengthens national food resilience, shortens supply chains, and removes the emissions associated with transporting fresh produce across borders. We believe this model can be replicated wherever large-scale data centers are built.” The announcement follows atNorth's partnership with Vestforbrænding to reuse surplus heat from its DEN01 data centre for the local district heating network. atNorth also works with Kesko Corporation in Finland to provide heat for a local shop, and with Stockholm Exergi at its SWE01 campus to supply heat for local homes and businesses.

GreenScale sets data centre sustainability commitments

GreenScale, a developer of hyperscale data centre campuses, has published 12 sustainability commitments that will guide the development and long-term operation of its data centre campuses. The commitments conclude a 12-week campaign that began on Earth Day 2026, with one commitment announced each week. Together, they set measurable targets covering areas including renewable energy, embodied carbon, water stewardship, local communities, and responsible supply chains. GreenScale says it will report publicly on progress against each commitment as its developments move forward. Among the commitments are designing all data centres to enable heat export whilst seeking opportunities to reuse waste heat, operating backup generators using hydrotreated vegetable oil (HVO) fuel, targeting a water usage effectiveness (WUE) score of 0.4 or below, and requiring major design and construction suppliers to achieve an EcoVadis rating of "Good" or higher. Campus designed around renewable power GreenScale says its sustainability strategy is linked to developing data centre campuses in locations with renewable energy resources and resilient connectivity. The company points to its planned Tonstad Campus in southern Norway as an example of this approach. New visualisations show the proposed 300MW campus, which is planned to comprise four data centre buildings across a 420,000m² site, representing more than €2.5 billion (£2.1 billion) in planned investment. Located next to the Ertsmyra substation and supplied by electricity from the nearby Tonstad Power Plant, one of Norway's largest hydropower facilities by annual electricity generation, the campus has been selected to take advantage of the region's renewable energy resources. Anna Dowson, Senior Director of Sustainability at GreenScale, says, "These commitments reflect the areas where we believe GreenScale can make the greatest positive impact. "By setting clear, measurable targets from the outset, we're creating a transparent way to track our progress over time and hold ourselves accountable as our campuses move through development and into operation." Dan Thomas, CEO of GreenScale, adds, "Data centre campuses are long-term infrastructure assets that will operate for decades. The decisions made before construction begin influence their performance throughout their lifetime. "That's why we've embedded sustainability into every stage of our approach, from selecting the right locations to designing, building, and operating our campuses. These commitments provide the framework that will guide that journey." GreenScale says the commitments were developed following a materiality assessment aligned with the European Sustainability Reporting Standards (ESRS), the Sustainability Accounting Standards Board (SASB), and the Global Real Estate Sustainability Benchmark (GRESB).

Equinix, A2A to heat Milan via district heating

Equinix, a US global data centre and interconnection services provider, and A2A, Italy’s second-largest energy operator, have announced a partnership to recover waste heat from a data centre campus near Milan and use it to supply the city's district heating network. The project will recover heat generated by servers at Equinix's campus in Settimo Milanese and transfer it to a new energy centre developed by A2A. The recovered heat will then be used to provide heating across parts of Milan. Equinix will design and manage the system used to export heat from the campus, working with customers whose IT equipment generates the thermal energy. A2A's new energy centre will use four large-scale heat pumps with a combined capacity of 72MW, together with two thermal storage systems capable of storing 6,000m³ of water. The facility will connect to Milan's district heating network via dedicated heat transport infrastructure. Once fully operational, the project is expected to recover up to 225GWh of thermal energy each year. According to the companies, this will increase the amount of heat distributed through A2A's district heating network by around 20%, providing enough energy to heat more than 21,000 homes. The partners also estimate the scheme will avoid more than 345,000 tonnes of CO₂ emissions. Heat recovery supports district heating expansion As part of the project, A2A will expand Milan's district heating network, enabling recovered heat from the data centre to be supplied across a wider area of the city, including the Duomo and Palazzo Reale, which are already connected to the network. Adaire Fox-Martin, CEO and President of Equinix, comments, "Equinix has a long and proud history of aligning the needs of our business with the needs of the communities we call home. "Our collaboration with A2A is a clear example of how essential digital infrastructure and local sustainability goals can work in service of each other. By putting thermal energy from our operations to use for local homes and residents, we're eliminating waste and moving Milan towards a low-carbon future." Emanuela Grandi, Managing Director of Equinix Italy, adds, "Excess heat is a by-product of the processing power required for digital transformation and AI, but when we redistribute it to the areas surrounding our data centres, we can create tremendous value for our communities while reducing the overall energy needed to heat the area. "We are very proud of the efforts and achievements Equinix has done in blazing a trail for data centre heat export in Europe and we're applying learnings from our successes to our efforts in Italy. "By scale, this initiative in Italy is expected to become among the largest data centre heat export projects in Europe outside the Nordics." Renato Mazzoncini, CEO of A2A, concludes, "Data centres are strategic infrastructure for the competitiveness of the country and for supporting the digital transformation of the economy. "Their growth requires models capable of combining technological innovation, energy efficiency, and environmental sustainability. From this perspective, heat recovery is a key lever for maximising the value of digital hubs and accelerating the decarbonisation of cities. "The collaboration with Equinix is fully aligned with our strategy to develop an integrated ecosystem where energy, infrastructure, and innovation operate synergistically." The companies say the partnership forms part of wider efforts to support the decarbonisation of urban energy systems through the reuse of waste heat generated by digital infrastructure.

EUDCA reaffirms sustainability commitment

The European Data Centre Association (EUDCA), the representative body of the European data centre community, has reaffirmed its commitment to supporting climate-neutral data centres and the sustainable growth of Europe's digital infrastructure. The organisation says it remains focused on developing a digital economy that balances increasing demand for digital services with environmental sustainability and closer integration with Europe's energy system. Founded in 2012, the EUDCA works with the data centre industry, policymakers, and other stakeholders to support the development of Europe's digital infrastructure. As a co-founder of the Climate Neutral Data Centre Pact, the association has committed to helping the sector achieve climate neutrality by 2030. This includes improving energy efficiency, increasing the use of renewable energy, reducing water consumption, supporting circular economy initiatives, and encouraging the reuse of waste heat. Over recent years, the EUDCA has worked with the European Commission and industry partners on policies intended to support both digital infrastructure growth and environmental objectives. Energy integration and grid capacity On 3 June 2026, the EUDCA joined the European Commission, Commissioner Dan Jørgensen, and organisations from across the energy sector in signing a Declaration of Intent to support the sustainable integration of data centres into the European energy system. The declaration highlights the need for reliable low-carbon electricity, closer collaboration between data centre operators, grid operators, and public authorities, and a stable regulatory environment to support future investment. The association also says that expanding Europe's digital infrastructure will depend on addressing wider challenges within the electricity system, including reinforcing transmission and distribution networks, streamlining planning and permitting processes, and improving access to low-carbon electricity. Michael Winterson, Secretary General of the EUDCA, comments, "We reaffirm our commitment to sustainability, irrespective of technological developments or changing demands. A liveable, equitable, and sustainable future remains our utmost goal." The EUDCA's annual State of European Data Centres report also tracks the sector's sustainability and environmental, social, and governance (ESG) performance using member data and information collected under the European Energy Efficiency Directive.

Global cities launch sustainable data centre pact

Cities from around the world have launched the Global Urban Data Centres Pact, a new initiative aimed at supporting sustainable data centre development in urban areas. Announced during London Climate Action Week, the pact brings together 38 cities across six continents, including London, Barcelona, Johannesburg, Miami, Melbourne, Phoenix, and Rio de Janeiro. The founding signatories represent a combined population of almost 90 million people. The agreement comes as demand for data centres continues to grow, driven in part by the expansion of artificial intelligence and digital services. City leaders say the pact is intended to help balance economic growth with concerns around energy use, water consumption, heat generation, and pressure on local infrastructure. The initiative sets out a framework for how cities, developers, investors, and operators can work together to support data centre growth whilst addressing environmental and community considerations. Cities seek sustainable approach to data centre growth Under the pact, signatories support data centres that are strategically integrated into cities, resource efficient, engaged with local communities, and capable of delivering wider economic benefits. The agreement also highlights examples of measures already being adopted in different regions, including heat reuse projects, water-conscious cooling systems, the use of renewable energy, and initiatives that direct investment towards local priorities. Kate Gallego, Mayor of Phoenix and Vice Chair of C40 Cities, says, "While data centres can power important advancements, rapid growth also brings important responsibilities. Residents expect local leaders to ensure development is planned carefully, infrastructure keeps pace, and surrounding communities share in the benefits." Nicholas Reece, Lord Mayor of Melbourne and Vice Chair of C40 Cities, adds, "Local communities should be involved in decisions that affect them, which means growth must be matched by responsible planning, sustainable resource use, and genuine community benefits." Sadiq Khan, Mayor of London and Co-Chair of C40 Cities, notes, "AI and digital infrastructure will play a major role in the future prosperity of cities around the world, but residents are right to expect growth to be managed responsibly." Additional support for the initiative has come from cities including Athens, Chicago, and Seattle, whose leaders highlighted the importance of managing the impacts of data centre development on energy systems, water resources, land use, and local communities. Framework developed ahead of continued sector growth According to the pact's organisers, global data centre capacity is expected to increase significantly over the coming decade, with much of that growth concentrated in urban areas. The agreement calls for greater collaboration between local authorities, national governments, and the private sector to ensure future data centre developments align with sustainability goals and community needs. Cristina Gamboa, CEO of the World Green Building Council, concludes, "Data centres are not just buildings; they are major, long-term consumers of critical urban resources, and the decisions being made today about these AI factories will shape local energy systems, water supplies, and communities for decades to come." Further city endorsements are expected ahead of COP31, as the initiative seeks to establish a shared approach to sustainable urban data centre development.

Experts urge sustainable requirements for new developments

Industry experts are calling on the UK Government to introduce stronger sustainability requirements for new data centre developments, following reports that the sector's future energy demand could exceed previous forecasts. The comments follow a report by The Times suggesting that growing demand from data centres could significantly increase national electricity consumption, driven in part by the rapid expansion of AI infrastructure. Concerns have also been raised over proposals for some large-scale developments to build dedicated gas-fired power generation to overcome grid capacity constraints. David Woon, Head of Net Zero Engineering and Operations at Ennovus Solutions, says, “The figures for the expected energy demand of data centres are staggering, but immediately pivoting to new gas power stations is incredibly disappointing. "The space and resources required to build a new gas power plant could almost certainly be used instead for significant renewable generation development - ideally utilising wind turbines to better match the consistent, 24/7 energy demand of these facilities. “While on-site renewables may not provide 100% of the baseline power required by these data centres, a forward-thinking country aiming for energy independence and climate mitigation should jump at the chance to integrate green generation directly into planning permissions. "We already mandate solar panels on new-build homes; why are we not implementing similar, strict sustainable development mandates for industrial-scale data centres? “Furthermore, as the Government considers mandating grid ‘flexibility’ from operators, we must look beyond standard battery technologies like lithium-ion. Long-standing, energy-hungry data centres need a technology that matches their requirements, like Vanadium Flow batteries. They are suited to large energy demand projects, provide up to double the lifespan of lithium-ion, experience no degradation, and avoid environmentally hazardous, scarce materials like cobalt and lithium. "If battery storage is on the table to support the National Grid, it is nonsensical not to bring on-site renewable generation into the exact same conversation.” Grid constraints remain a major challenge Lee Ackerman, Utilities General Manager at Connectus Utilities, adds that while infrastructure upgrades are possible, they are likely to require significant investment and lengthy delivery timescales. He says, “The reality is that, while resolving these infrastructure bottlenecks is physically possible, it carries massive cost and time implications. "The National Energy System Operator (NESO) and Ofgem have transitioned the grid from a ‘first come, first served’ model to a ‘first ready and needed, first connected’ approach. "While major structural upgrades, new on-shore power lines, and smart grid sensors are scheduled for rollout between 2026 and 2028, there is an immense amount of work to do before we see true grid relief by 2030. “Every utility connection faces identical hurdles: cable lengths, land access, and complex legal processes. It’s not just an electricity problem either; data centres require major water capacity for cooling. “Developers could and should be targeting the Environmental Discounts offered in Water Charging Statements, aiming for Tier 2 or Tier 3 water neutrality incentives through advanced rainwater harvesting and greywater recycling. "Some might argue that technology will naturally become more efficient over time, but history shows that as components shrink, developers simply pack more technology into the same footprint. The energy demand isn’t going to drop on its own; we must build [in] sustainability from day one.” The comments highlight growing debate around how future AI and data centre infrastructure should be powered, with industry figures calling for greater emphasis on renewable energy generation, long-duration energy storage, water efficiency, and sustainable design principles during the planning process.

Pure DC completes cross-border biomethane deal

Pure Data Centres Group (Pure DC), a designer, developer, and operator of hyperscale data centres, has completed what it describes as Europe's first large-scale cross-border biomethane purchase for a data centre, transferring 9GWh of certified biomethane from Germany to the Irish gas network. The transaction follows a proof-of-concept project announced in March 2026 and represents a significant increase in scale. According to Pure DC, the deal demonstrates that biomethane can be used to support the decarbonisation of gas-connected data centres through existing energy infrastructure and certification frameworks. The biomethane was produced in Germany during 2025 using waste and residue feedstocks. The fuel is certified under the International Sustainability and Carbon Certification (ISCC) scheme and complies with the requirements of the Renewable Energy Directive (RED) II and RED III. Pure DC says the biomethane has a carbon intensity of less than 12gCO₂/MJ, meeting thresholds required for zero-rated treatment under the EU Emissions Trading System, subject to approval of monitoring plans by the relevant authorities. The gas was mass balanced from the German network to Ireland through existing interconnectors, with renewable attributes tracked through the Gas Networks Ireland (GNI) Renewable Gas Registry. Biomethane forms part of wider net zero strategy Pure DC says renewable gas is intended to act as a transitional measure within its broader strategy to achieve net zero emissions by 2040. The company is continuing to pursue biomethane procurement from Irish, European, and UK sources while also developing longer-term initiatives including renewable energy integration, energy storage, and efficiency improvements. Ireland's National Biomethane Strategy targets production of up to 5.7TWh of domestic biomethane annually by 2030. While local production capacity continues to develop, imports can help meet demand through existing gas infrastructure and certification systems. Maria Jose Rivas Duarte, Director of Sustainability at Pure DC, says, "This milestone supports Ireland’s Climate Action Plan and aligns with the LEU policy, under which data centres must meet at least 80% of their annual energy demand with additional renewable electricity. "By demonstrating that cross-border biomethane can be procured, mass balanced, and registered at volume through existing infrastructure, we are helping to pave the way for broader data centre sector adoption as well as other industries seeking a credible route to decarbonise natural gas." Pure DC says the transaction forms part of a strategy to develop a diversified biomethane portfolio spanning multiple geographies, feedstocks, and supply arrangements. Agnes Warner, Property Director at Pure DC, says, "Our biomethane procurement strategy is designed to build a balanced portfolio that provides long-term security and credibility. "For our customers, this means a demonstrable, auditable pathway to lower embedded emissions, making our platform more attractive to hyperscalers and enterprise customers while supporting their sustainability commitments."
