As the EU sharpens its focus on climate leadership - setting the stage for a 90% net reduction in greenhouse gas emissions by 2040 - the pressure on companies to deliver meaningful, measurable change has never been greater.

But behind every sustainability report, roadmap, and reduction target is a person - often several - working tirelessly to bring those ambitions to life. These are the sustainability managers translating vision into execution, balancing science, strategy, and internal politics to drive progress from the inside out.

Last year, Coolset launched the Future 15 to spotlight this critical - and often unsung - talent. This year, we’re proud to bring the list back with even more depth, diversity, and impact.

Why we created the Future 15

Sustainability professionals are leading one of the most urgent transformations in business history. Yet their work rarely makes headlines. At Coolset, we believe that recognition matters - especially when it’s paired with substance. Future 15 is about shining a light on the individuals who are not only advancing ESG goals but redefining what modern leadership looks like in the climate era.

These are the rising stars whose influence will shape how industries decarbonize, how companies adapt, and how systems evolve.

What we asked

We asked the same questions as last year - because the fundamentals haven’t changed. This year’s nominees were asked to share:

• A sustainability project they led or significantly contributed to in the past year
  
  
• The measurable environmental, social, or governance (ESG) impact of that project
  
  
• How they integrate sustainability into business strategy and operations
  
  
• What innovative technologies or approaches they’ve introduced
  
  
• The key sustainability challenges facing their industry
  
  
• How they plan to address them
  
  
• And finally, what advice they would give to others entering the field
  

How we selected the 15

Our judging panel reviewed every submission using a detailed scoring framework. We looked at impact, innovation, clarity, and ambition - but also at the ability to deliver practical results in complex organizational environments.

The bar was higher this year. As the field of sustainability continues to grow, so does the calibre of talent. The 15 individuals featured here stood out for their clear thinking, actionable impact, and contagious sense of purpose.

Now, without further ado, meet the change makers (in no particular order) defining the next chapter of corporate sustainability: Coolset’s Future 15 – Class of 2025.

#1 Camilla Cederquist

Role: Manager, Atea Sustainability Focus
Company: Atea
Experience: 6 years in sustainability
HQ location: Oslo, Norway
Industry: Information Technology
Company size: 2,000–10,000

Elevating Nordic voices in global IT

“I lead our initiative Atea Sustainability Focus (ASF) that gathers insights about the Nordic market's sustainability priorities and expectations on suppliers to accelerate the sustainable transformation of the global IT industry,” says Camilla Cederquist. The insights are delivered to the Responsible Business Alliance (RBA), a coalition of major tech brands. “This partnership is key to deliver results.”

ASF has given end users a meaningful voice. “ASF is a platform that brings together the industry and its customers which is essential if we are to solve the major challenges our industry faces.” A major outcome has been progress on circularity. “Before, the RBA did not focus on circularity at all, but it is now a major focus.” Key milestones include co-founding the Circular Electronics Partnership and launching Zero Waste Assurance programs.

Building a circular and strategic approach to IT

“Sustainability has been at the core of Atea's business for many years,” Camilla explains. “All our offerings are assessed for sustainability and some offerings are built with sustainability as a foundation.”

Two key goals shape Atea’s impact: “The 1:1 goal – taking back as many devices as we put on the market, and our 100:1 goal – helping our customers cut their carbon emissions so that our handprint is 100 times larger than our footprint.” The company’s annual CSRD-aligned report integrates financial and sustainability data.

Atea also applies technology internally and with customers: “One example for our internal operations is business-intelligence tools that track carbon footprint on an office level… A customer example is the use IoT technology to optimize energy use in buildings.”

Camilla's advice to future professionals

“If you are looking to work in a company, my best advice is combine sustainability competence with business knowledge. The biggest sustainability issue of tomorrow is the redesigning of business models.”

Role: Head of sustainability
Company: Depop
Experience: 9+ years in sustainability
HQ location: London, UK
Industry: Software technology
Company size: 201–1,000

Quantifying impact through circular fashion

#3 Jorick Bots

Role: Sustainability & CSR Manager
Company: ilionx
Experience: 7 years in sustainability
HQ location: Utrecht, Netherlands
Industry: Professional services (consulting)
Company size: 1,001–2,000

Making software sustainability measurable

At ilionx, Jorick Bots is helping drive greener IT with practical tools. “At ilionx we have developed a Sustainability by Design scan that helps clients gain an initial understanding of how sustainable the software they have built or use is. This provides users with insights into which ‘levers’ they can pull to make the software more energy-efficient and, therefore, more sustainable.” The tool is also applied internally, and the team is now measuring the effectiveness of different actions. “We not only raise awareness among our clients about the footprint of IT, but we also offer concrete options that actually make IT greener.”

Driving strategic and sector-wide change

“Sustainability and CSR are part of the ilionx strategy. By positioning them at the forefront of our organization, we both recognize the innovative nature of sustainability and emphasize that sustainability and CSR are much more than just a box-ticking exercise.”

ilionx has also developed a green customer journey with four phases—Rethink, Record, Report, and Reduce—each supported by tailored IT services. “As an IT service provider, we believe that IT plays a key role in the sustainability transition.”

Jorick sees a growing urgency for action. “The emissions from our industry are already greater than those of the global aviation sector… With the rapid development and adoption of AI, the energy consumption of data centers is expected to increase even further.” ilionx is responding by investing in measurement tools, advising clients, and participating in a national coalition to help position the Netherlands as a leader in sustainable digitalization.

Jorick's advice to future professionals

“Just do it. Sustainability can be applied to everything. Even if you haven’t studied it, you can still be of great value to many companies. We need all the help we can get to get everyone involved in the sustainable transition. Also, start measuring as soon as possible... what gets measured, gets managed.”

#4 Joyce Power

Role: Sustainability Manager
Company: DO & CO AG
Experience: 8 years in sustainability
HQ location: Vienna, Austria
Industry: Food and beverage services
Company size: 10,000+

Building sustainability into systems and strategy

At DO & CO, Joyce Power led the successful delivery of an Ecolabel License for the company’s Events division. “Over the past year, I led the successful delivery of an Ecolabel License for our Events division, awarded after a rigorous audit by Ecolabel Austria… A key ingredient to success at DO & CO has been strong stakeholder engagement — working not just to implement, but to embed sustainability into core functions and operations.” She also aligned digital and ESG goals through an IT ESG Charter.

The work has already been recognized: “The Ecolabel project not only secured our audited license but also earned us recognition as a Sustainable Business (ÖkoBusiness Wien) by the City of Vienna.” Though full impact data will be shared in the upcoming Annual Report, her leadership has unified global waste-reduction projects and embedded sustainability into operations across departments.

Scaling data, impact, and digital alignment

Joyce played a central role in implementing new reporting systems: “I managed the team responsible for implementing the new ESRS/CSRD data collection tool and a separate sustainability reporting platform… rolled out globally to ensure compliance.”

Her approach is grounded in cross-functional engagement. “I aim to identify areas for improvement that support the greatest benefit to our collective agenda. I also ensure that every team member understands the ‘why’ behind sustainability efforts.”

Looking ahead, she sees growing risk from climate and supply chain pressures. “Over the next five years, I expect to see significant changes… lower crop yields, water scarcity, and biodiversity loss… will affect the availability and cost of products and the livelihoods… across our supply chain.”

Joyce's advice to future professionals

For Joyce, success in sustainability starts with deeply understanding the organization you're working within. “Understand the business and its internal processes before attempting to make changes,” she says. “Link company goals, and align department roadmaps—i.e. digital transition with IT.”

She stresses that change doesn't happen in isolation, and building relationships is key: “Stakeholder engagement is crucial—understanding their challenges and explaining the 'why' behind your goals is key.”

Her parting advice is simple but powerful: “Sometimes, you need to fix the soil before you can plant a thriving garden.”

Company: La Prairie Group AG
Experience: 5 years in sustainability
HQ location: Zurich, Switzerland
Industry: Manufacturing and production
Company size: 2,000–10,000
