At our Maarssen location, we welcomed 78 12-year-old students from Yuverta. Together with our business units, Eurofiber Netherlands and Cloud Infra, as well as our partners Spie and Circet, we provided the girls with an exclusive behind-the-scenes look at the world of fiber optic and cloud technology.

The students explored various aspects of technology, including cybersecurity, data centers, and the career opportunities the tech industry has to offer. They also had the chance to experience hands-on activities, including fiber optic splicing, with the expert guidance of our partners Spie and Circet.

This day provided a unique opportunity to inspire the girls and show them the exciting possibilities within the tech sector. We would like to thank VHTO for organizing this valuable initiative, as well as our partners Spie and Circet for their collaboration in the fiber optic splicing activity.

About VHTO Girls Day
VHTO, the Dutch expert center for gender diversity in STEM, organizes this day to inspire young girls and broaden their perspectives by providing them with real-world insights into technical careers. This year, over 10,000 girls across the Netherlands participated.

Partner organizations who facilitated SBTi’s growth and development are CDP, the United Nations Global Compact, the We Mean Business Coalition, the World Resources Institute (WRI), and the Worldwide Fund for Nature (WWF). In its role as a corporate climate action organization, the SBTi helps companies worldwide set science-based emissions reduction targets in line with what is needed to keep global heating below catastrophic levels.

A roadmap to net-zero
Eurofiber  commits to reaching net-zero emissions across its value chain by 2040. By 2030, it will cut scope 1 and 2 emissions by at least 90% from its 2021 baseline, ensure 100% renewable electricity sourcing, and reduce scope 3 emissions by 30%. From 2030 to 2040, it will maintain a minimum 90% reduction in scope 1 and 2 emissions and further reduce scope 3 emissions by 90%, fully aligning with its net-zero target.

Eurofiber has already significantly reduced its carbon footprint for scope 1 & 2 (direct emissions and electricity purchases) in recent years; this now amounts to only approximately 3% of our entire CO2 footprint. In order to also achieve our objectives in our supply chain (scope 3), we have established a supplier engagement program to inspire, enthuse and advise Eurofiber’s suppliers on improving sustainability of their products and organization. This will result in a further reduction of CO₂ emissions in our supply chain in the coming years, moving towards net-zero in 2040.

Sustainability at the core of business strategy
Eurofiber has a leading role in society in the field of digital infrastructure. We believe that this entails a broader responsibility, and are firmly committed to pursuing sustainable growth for our own organization, for our employees and for society as a whole. Our ESG policy encompasses sustainable production at our suppliers, an inclusive work environment for our employees, and climate change mitigation, including innovations serving the energy transition and the digital transition. In May 2024, Eurofiber was ranked in the top 1% of best-performing companies globally by EcoVadis, acknowledging the company’s strong ESG program.

Not only is Eurofiber moving towards an increasingly international focus in its business activities, but Eurofiber's ESG team is also taking on a leading role internationally. Together with NLconnect, the Dutch IT-sector organization, Eurofiber has joined a consortium of 18 parties working on preparing Product Category Rules (PCR) for active and passive equipment in fiber optic networks. Worldwide, companies can now use these PRCs to prepare Life Cycle Assessments (LCA) for their products.

Jeroen Kanselaar, ESG manager at Eurofiber, chairs the Sustainability Committee of the FTTH Council. This committee recently launched the FTTH Eco Platform, which supports companies in the sector in calculating their CO₂ footprint at an organizational level. Uniquely, the Eco Platform also offers outcomes of carbon emission impacts for the entire European sector. Kanselaar is also co-lead of the Green Digital Action program of the International Telecommunication Union (ITU), bringing together partners worldwide to advance climate action through digital innovation.

Eurofiber’s strategy for achieving these Net-Zero Targets is in line with the FTTH Council ambitions to create a digital and sustainable Europe with full fiber.  Similarly, it is aligned with the ITU calls to action at COP28 as well as the ITU Declaration on Green Digital Action at COP29.

According to the latest EcoVadis sustainability rating (May 2024), Eurofiber Netherlands has attained the highest achievable status: Platinum. In attaining this platinum position with its ESG initiatives, Eurofiber has reached the top 1% high-performing companies, out of a total of 130,000 rated by EcoVadis worldwide.

Among other things, Eurofiber’s ESG program resulted in an SBTi-approved 100% reduction in CO2 in 2030 compared to 2021 (scope 1 and 2 emissions). The ambition is to be 100% climate neutral in 2040 (scope 1, 2 and 3).  To achieve this, Eurofiber is working on various sustainability initiatives. Examples include exclusively using sustainably generated electricity, adopting a lease policy focused on 100% electric driving, reducing energy consumption in the supply chain, and increasing circularity of products. 
Pilot projects on carbon-neutral construction and maintenance of the Eurofiber network and reductions in packaging materials will be starting shortly. To promote circular deployability of equipment, Eurofiber is also constantly exploring new opportunities for re-use.

With a platinum-standard final rating, Eurofiber scored higher than 99% of all companies rated by EcoVadis worldwide. The company recently scored 80 points in the sustainable procurement category – a substantial improvement compared to last year.

“Obviously, we are proud of this independent acknowledgement of our Platinum status by EcoVadis. In recent years, we have been making great strides with our Environment, Social & Governance goals and initiatives. Besides various projects to reduce CO2 impact in line with our SBTi ambitions, at the end of 2023 we asked over 40 of our key suppliers to join us in registering with EcoVadis. This enables us to monitor the ESG targets and results of our supply chain as well,” says Jeroen Kanselaar, ESG Manager at Eurofiber.

About EcoVadis
Since the independent agency was founded in 2007, EcoVadis has grown to become the world’s largest provider of business sustainability ratings, creating a global network of more than 100,000+ rated companies in over 180 countries. The EcoVadis Medals are awarded to the top 35% of companies rated by EcoVadis.

Key ESG results achieved by Eurofiber in 2023:

- Eurofiber’s CO2 reduction targets have been approved by the Science Based Target initiative (SBTi) and the CO2 reductions we have achieved in 2023 are ahead of schedule for these targets.

- Progress has been made in the area of circularity; after use, 70% of CPEs returned by customers have been refurbished for reuse in our network. 

- In the pillar Social, Diversity & Inclusiveness, an internal training course was developed: Unconscious Bias.

The aim of MISD is to develop a new modular, sustainable and secure-by-design concept to be deployed in places close to end users (edge computing). The guiding principle is to achieve a significant reduction in total energy consumption, from cooling to computing power and data flows. Thereby, a CO2 reduction of more than 50% is set to be achieved in a validated, distributed setup in a field lab where different innovations developed in the project converge. The duration of the project is 5 years, from 2024 to 2029.   

The MISD consortium is thus taking the lead in European partnerships to embed sustainable applications into the foundation of the next generation of European cloud infrastructure and services. Maikel Bouricius, CMO of lead partner Asperitas on the project: "The MISD project is the outcome of years of collaboration in the Netherlands on energy-efficient data centers. Many stakeholders were involved in the initial phase to shape this initiative and this funding makes it possible for the Netherlands to be a development hub for the next generation of data centers. There are more field lab initiatives in Europe, but the distributed set up, scale and variety of innovations it will welcome is unique." 

Pioneering technology
The award of the funding is an important step towards the cloud infrastructure of the future. The consortium participants aim to develop a sustainable answer to the growing demand for (local) data center capacity in a more flexible way than is currently possible.  Bouricius: "Asperitas will work on the big challenge for cooling in the coming years. Compute requires more and more power, space and water, and advanced liquid cooling solutions are needed to make this growth sustainable. Optimal results require collaboration with a broad ecosystem, which this project makes possible."   

Sustainability is thus an important cornerstone of the project, underlines Theo Balijon, Digital Transformation Officer at BetterBe. "We will contribute to the development and realization of modular energy-efficient data center housing with distributed cloud infrastructure platforms. In addition, we will investigate how reduction of CPU cycles can be realized in application software." 

Jonathan Clark, Data Centre Sustainability Lead at Deerns said: “We are proud to be part of the consortium driving the creation of a 'Modular Integrated Sustainable Data Centre of the Future' in the Netherlands. In collaboration with partners we are pioneering innovative solutions for data centers. This groundbreaking project underscores Deerns MEP's design, building physics, energy concepts and energy efficiency modelling. These modular, integrated and sustainable solutions set new benchmarks for design excellence eco-friendliness.” 

Distributed data center workloads
Another important way to maximize the energy efficiency of the infrastructure to be designed is to spread workloads within the distributed network to those places where there are surpluses of renewable energy. This requires solid fiber-optic connections. Eurofiber brings its expertise to this theme, among others. "The development of a staging lab and a -via fiber connected- geographically distributed field lab environment will be part of our contribution to this project. Developing energy, data and compute use cases is also part of this," says Martin Vos, Business Innovation Director at Eurofiber.  

Given the constantly changing online threat landscape, security by design is a key focus: the infrastructure will be designed with availability and security in mind. "NBIP will investigate how the availability of online services can be secured in this new cloud infrastructure, for example by distributed DDoS mitigation. In the field lab, we want to demonstrate that a secure by design distributed setup makes cloud infrastructures more secure and reliable", said Octavia de Weerdt, director of NBIP.   

A more sustainable cloud
Ultimately, the project should enable a more sustainable cloud. To that end, it is important to make climate impact measurable. Marc van Dijk, TNO portfolio lead Digital Infrastructures: "We are investigating how sustainability parameters in distributed and federated data centres can be used to reduce the climate impact of cloud use. The software components we develop will make data centers contribute more to the flexibility needed in power grids to better deal with the variation in supply and demand of (green) energy."  

Finally, the University of Twente focuses on four sustainability-oriented lines of research, describes  Maria Vlasiou, professor of stochastic networks. "These include scalable, sustainable, innovative computational approaches for data center operations and data centers as active support for the power grid. We will also focus on advanced thermal management for sustainable cooling and heat utilization, software solutions for secure multi-party cloud systems, and stakeholder engagement through learning communities for inter-organizational learning and innovation implementation."  

Educating the public and stakeholders on progress
The consortium is developing a website to keep stakeholders and interested parties informed of the project's progress. In addition, consortium participants will proactively share their knowledge gained during the project, for example during events, workshops, knowledge sessions and webinars.   

About the Modular Integrated Sustainable Datacenter (MISD) project
MISD will start in 2024 as a joint project of Asperitas, BetterBe, Deerns, Eurofiber, Nationale Beheersorganisatie Internet Providers (NBIP), TNO and University of Twente to develop a new generation of sustainable, energy-efficient, modular and secure-by-design data centers. To this end, the consortium has received funding from the Dutch Ministry of Economic Affairs and Climate in late 2023 under the European Important Projects of Common European Interest - Cloud Infrastructure and Services (IPCEI-CIS) program. The MISD project will run for five years.   

Innovations resulting from the project will come together in a geographically distributed field lab. Research and development will include new liquid cooling techniques, making housing and compute more energy efficient, security by design in a distributed cloud infrastructure, parameters for the climate impact of cloud usage and its reduction, and data centers as support for a more flexible energy infrastructure. The consortium will launch a website in 2024 to inform about, and engage stakeholders and the public with the project's progress. 

The challenge of SBTi is to limit global warming to 1.5°C and prevent the worst effects of climate change. With the aim to mobilizes the private sector to take the lead on urgent climate action. The SBTi is a partnership between CDP, United Nations Global Compact, World Resources Institute (WRI) and the World Wide Fund for Nature (WWF).

‘’We’re proud to receive this internationally recognized approval by SBTi. This further encourages us to take the right steps in our sustainability ambitions for Thought Leadership in the ESG (Environment, Social and Governance) field’’, says Jeroen Kanselaar, Manager ESG of Eurofiber.

Official approved science-based targets commits Eurofiber to reduce absolute scope 1 and 2 GHG emissions 90% by 2030 and our scope 3 emissions by 30% from a 2021 base year. Eurofiber commits to increase active annual sourcing of renewable electricity from 95% in 2021 to 100% by 2025 and to continue active annual sourcing of 100%.

Last year Eurofiber completed a Euro 1.5 billion sustainability-linked refinancing supporting further network expansion across Europe. The facilities and the related hedging have sustainability incentives in alignment with Eurofiber’s sustainability program, which includes, among other things, measures that will lead to a 50% CO2 reduction by 2025 (compared to 2021), furthering the company’s stated goal to be 100% climate proof by 2030, as well as measures regarding gender balance. For this facility Eurofiber received the GlobalCapital's Sustainability Linked Loan of the Year Award, one of the leading information sources of the international capital markets. 

Eurofiber ESG ambitions & 2022 ESG report 

The Eurofiber cycling team took part again this year, pedalling hard to collect a fantastic 11,195 euros with their efforts. This year’s event raised over 1 million euros for this charitable cause: individual cancer research. In contrast to last year’s cold and rainy weather, this eleventh edition had nothing but sunshine. The view during the climb was breath-taking, enjoyed by participants and volunteers alike. The Stelvio For Life organization had arranged every detail to perfection; once the mayor of Bormio had announced the total amount, it was party time on the village square at Piazza Cavour. It was unforgettable. Special thanks to everyone for the support and donations! We look forward to seeing you again next year.

Over Stelvio For Life
This foundation believes in a treatment for cancer patients based on the DNA profile of their tumour. To make this all happen, and to be able to give patients a longer and better life,  Stelvio For Life raise money for individualised cancer research. 
That, together with the passion for sports, results in the annually returning charity sports event: Stelvio for Life.
