Our answer is culture
Employees are empowered to incorporate sustainability into daily activities, ultimately creating the bottom-up support needed for an effective top-down execution of CSR targets
Have fun
Cultural development needs to be fun and easy. We make corporate culture and climate action entertaining without any compromise.
Engage everyone
From CEO to intern, from the headquarter to facilities – everyone must live the change. We involve them all with one simple email per week.
Measure it
Measuring CO2 is one thing, measuring a future-proof culture is another. Dashboards visualize your progress and make culture tangible.
One-stop solution for a complex issue

One eco-challenge per week
The eco-challenges, along with a tangible fact about their impact, are sent via email to all employees during eight consecutive weeks. After a season is completed, the results are summarized in both a dashboard and impact report.
Collective motivation
Employee motivation is boosted by showing them the number of colleagues who have joined them during the last eco-challenge. This creates a gamified and collective incentive needed to transform the culture from the inside out.
Impact reports
After eight weeks, a season is completed and a science-based questionnaire measures the employees’ cultural development. Dashboards visualize the progress and give clear recommendations for both leadership and employees. Culture becomes tangible.
