Coolset gave us the support to finally get a grip on our sustainability data and helped turn a complex challenge into actionable results.
PIA Group is a collaborative organization of independently operating accountancy and financial advisory firms across the Netherlands. With a mission to future-proof its member offices, PIA provides support in HR, innovation, marketing, and investment. By enabling scale without sacrificing local autonomy and culture, the group empowers its members to thrive in a rapidly changing business landscape.
Sustainability plays a critical role in both their internal operations and the services they offer clients. As part of their long-term strategic planning, PIA has prioritized environmental responsibility as a core focus area.
Before partnering with Coolset, PIA Group faced the complex task of collecting sustainability data from a growing network of affiliated offices. Eight at the time, now fourteen. Many of these organizations had limited visibility into their carbon footprint, and gathering the right information (e.g., travel data, building emissions) proved burdensome and time-consuming.
PIA’s decentralized structure made it difficult to align on common metrics and expectations, particularly around CSRD (Corporate Sustainability Reporting Directive) requirements. The team needed a platform that could support both internal reporting and external audit preparation across varied data maturity levels.
As an accountancy group also involved in CSRD audits for clients, PIA values using a fully auditable platform, ensuring both internal compliance and alignment with the standards they apply in their own assurance work.
PIA Group selected Coolset for its platform-first approach to sustainability compliance. Unlike consultants, Coolset offers a self-serve solution with clear workflows, accessible templates, and built-in guidance, making it easier for PIA to scale their efforts without relying heavily on consulting hours.
The team appreciates Coolset’s continuous updates, responsive support via Q&A tooling, and peer learning opportunities through regular accelerator sessions. Compared to other tools, most of which are either immature or consultancy-led, Coolset stands out for its ease of use and practical orientation.
Since implementing Coolset, PIA Group has achieved much greater clarity over what data needs to be collected, and how. The platform’s templates and standardized formats helps them gathering data from their affiliated offices efficiently, enabling consistent data delivery and progress tracking.
For the first time, the group has a clear understanding of which transactional, personnel, and operational data they need to monitor on a rolling basis. This foundational work has laid the groundwork for further KPI tracking, and made footprint calculations for Scope 1, 2, and 3 emissions significantly more manageable.
“Coolset helped us move from scattered data and ambiguity to a clear plan and practical next steps. We now know where we stand, and what’s needed moving forward."
PIA Group experiences the partnership with Coolset as collaborative and hands-on from the very beginning. The personal contact with the Coolset team, particularly through regular check-ins and onboarding sessions, creates a strong sense of alignment and support. Questions are answered quickly, and the team is always approachable and proactive in offering guidance.
When challenges arise - such as uncertainty around reporting structures or data sourcing - Coolset’s support team responds quickly with practical solutions. This responsiveness enables PIA to maintain momentum and deliver results without getting bogged down in bottlenecks.
What stands out most is Coolset’s responsiveness and personal approach, creating the feeling of a partnership rather than just a software provider.
With the foundations laid through their work with Coolset, PIA Group is now deepening its sustainability initiatives. The clarity gained around required data, key metrics, and reporting frameworks has enabled the organization to expand its internal capacity and further embed sustainability tracking into day-to-day operations.
Looking ahead, PIA is focused on using data to drive accountability and progress, building on the groundwork established during their collaboration with Coolset.
