How can telecom firms align climate goals with business challenges?

Nuuday is on a mission for sustainability, striving for net-zero emissions and encouraging everyone to get involved.


In a world where climate change is no longer a distant threat but an immediate reality, companies are stepping up as stewards of the planet. Nuuday, a leading provider of telecommunications, connectivity, and entertainment services, is embracing this challenge with a firm commitment to sustainability. With a family of brands that includes YouSee, TDC Erhverv, Telmore, Hiper, eesy and Relatel, Nuuday aims to help customers "make sense with technology." But what does it truly mean to lead in sustainability? How can a corporation measure its climate footprint and take significant steps to reduce it? The answers lie in Nuuday's proactive approach to climate accountability.

As a market leader in Denmark, Nuuday understands its significant responsibility to create the best conditions for its employees, customers, and the society it serves. However, this ambitious goal comes with its own set of challenges. The company faced the complex task of effectively measuring and reducing its greenhouse gas emissions across a diverse range of services and products. With an extensive portfolio serving both consumers and businesses, mapping reduction potentials was no small feat. 

As a large, complex company, starting to map reduction potentials is not necessarily a straightforward task.

The journey toward net zero emissions for Nuuday began with a crucial first step: developing a climate account. This tool was essential for measuring emissions and setting internal reduction targets. However, Nuuday quickly recognized that creating a climate account was just the beginning. To effectively guide their climate efforts, they needed a well-prepared transition plan.

A transition plan describes how a company can transition into becoming net zero and lists the activities that need to be implemented in order to reduce emissions.

This is where the collaboration with EY teams came into play, providing the strategic insight necessary to navigate the complexities of climate accountability.

Crafting a net zero strategy aligned with customer needs

With EY teams, Nuuday built a net zero framework centered on customer engagement and insights.

EY teams and Nuuday have worked together successfully for several years. When Nuuday first reached out, they sought assistance in updating their Scope 3 climate account. This initial collaboration involved the collection of data and calculation of emissions, a process that teams at EY supported annually for three years. This process helped Nuuday strengthen its emissions calculations and establish a solid baseline, ensuring accurate reporting and setting ambitious yet achievable targets.

Through this partnership, three significant milestones were achieved:

Updated climate account: EY teams collaborated with Nuuday to enhance their climate accounting tool by integrating emission factors, optimizing estimation and assumption-based calculations, and simplifying the climate account setup. This allows Nuuday to update their data with greater ease in the future.

Development of a climate transition plan: Recognizing Nuuday's interest in applying for the Science Based Targets initiative, EY teams proposed a phased approach. This approach included creating a comprehensive climate transition plan based on existing data from their climate account, along with valuable input from stakeholders across the Nuuday organization.

Approval of science-based targets: With the updated climate account and transition plan in place, Nuuday not only successfully submitted their targets for approval but also received approval from the Science Based Targets initiative (SBTi). This achievement streamlined the approval process and minimized the typical follow-up questions, reflecting Nuuday's commitment to climate action.

It's important for us that our work with sustainability and climate change does not only become an exercise in reporting but contribute to make a real difference.

The collaboration between Nuuday and EY teams proved to be more than just a compliance exercise. It laid a strong foundation for Nuuday's future sustainability initiatives. "It has been exciting to see how Nuuday has actively taken on the task of working strategically with their climate efforts," remarked Josefine Lysdal Wulffeld, Manager, Climate Change and Sustainability Services, EY. "With their newly developed transition plan, a solid foundation has been set, and we are eager to see how they implement these activities in the future."

Nuuday's commitment to climate mitigation goes beyond the transition plan; it marks the beginning of a deeper integration of climate awareness into their business operations. The company aims for zero emissions for Scope 1 and 2 by 2028 and a 70% reduction in Scope 3 emissions by 2030, with a goal of achieving net-zero emmissions by 2040.

"Achieving a climate-neutral society requires collective effort," noted Isabella Rose Nygaard Lensborn, Head of ESG & Sustainability, Nuuday. "It's essential to bring others along on this journey." This collaborative spirit is reflected in their ongoing dialogue with suppliers, customers, and partners, emphasizing the importance of shared goals in reaching a climate-neutral future.

As Nuuday continues its mission, the commitment to sustainability remains crucial. The expertise provided by EY teams in sustainability legislation and strategic climate advice will help Nuuday navigate future legal requirements and engage in meaningful dialogues with suppliers, customers, and partners.
