Workshops, training programs, and conferences designed to build understanding, engagement, and action across your entire organization. Belgium's most comprehensive sustainability learning catalog.
Build a culture of sustainability that lasts
Regulations are pushing organizations to act, but real transformation comes from within. It starts when teams understand the challenges, see their role in solutions, and have the tools to drive change.
Our workshops and training programs combine scientific rigor with engaging formats that stick. Teams don't just learn about sustainability, they experience it, discuss it, and leave ready to act on it.
Transform knowledge into action.
Our Workshops
Our workshops combine scientific rigor with engaging formats to create lasting impact. Teams don't just learn about sustainability challenges, they collaborate on solutions specific to your organization.
Trainings
Join scheduled sessions with professionals from other organizations. Learn alongside peers facing similar challenges, exchange perspectives, and build your network while developing practical sustainability skills.
Conferences
Organize a dedicated workshop tailored to your organization. We adapt the content to your sector, challenges, and strategic priorities. Your teams engage in a safe space to explore complex topics and co-create solutions that fit your reality.

They learned with Bleen
Partenamut: Scaling Climate Awareness Across 1,400+ Employees
Scaling Climate Awareness Across 1,400+ Employees. Through the 2tonnes workshop methodology, we engaged over 1,400 Partenamut employees in climate action, achieving 90%+ satisfaction. The program built internal facilitation capacity and sparked concrete initiatives, transforming climate awareness into a cultural movement.
Pluxee: Co-creating a Consumption Awareness Movement
Co-creating a Consumption Awareness Movement. We co-designed an interactive Consumption awareness workshop with Pluxee, building everything from pedagogical content to facilitator training programs. The collaborative approach ensured internal buy-in and created a scalable movement around sustainable consumption across the organization.
Danone: Scaling Climate Literacy with 2tonnes Workshops
Scaling Climate Literacy with 2tonnes Workshops. Danone wanted to engage its teams on climate challenges and the role individuals and organisations can play in the transition. We delivered 2tonnes workshops with a debrief anchored in Danone's context, identified key levers for reducing carbon footprints, and scoped a train-the-trainer path for internal deployment.
IKEA: Greenwashing Awareness for Marketing Teams
Greenwashing Awareness for Marketing Teams. IKEA wanted its marketing teams to recognise greenwashing risks and communicate sustainability initiatives with transparency. We ran the Greenwashing Fresk, co-created by Bleen and GiveActions, across four marketing functions, with hands-on exercises using real IKEA campaigns and a train-the-trainer path for scale.
Air Liquide: A Multi-Year Climate Ambassador Programme
A Multi-Year Climate Ambassador Programme. Air Liquide engaged Bleen on a multi-year partnership to build a lasting internal sustainability culture. We kicked off an ambassador community across Northern Europe, created two in-house quizzes on water and energy, and trained internal facilitators to deploy awareness tools independently.
RTBF: Building Internal Capacity for Digital Sustainability
Building Internal Capacity for Digital Sustainability. After a Digital Collage workshop, RTBF wanted to train its teams on the environmental impact of digital technologies on a continuous basis. We designed a tailor-made "Tech Fresk" for the public broadcaster and trained internal facilitators so RTBF could keep running awareness sessions independently.
Drees&Sommer: Biodiversity Quiz for Construction Consultants
Biodiversity Quiz for Construction Consultants. Drees&Sommer wanted to raise biodiversity awareness among its Belgian team, with a format adapted to the construction sector. We co-designed a hybrid interactive quiz anchored in real project examples, tested it iteratively, and delivered it in a mixed virtual and on-site session.
Construcity: Integrating Climate into Construction Training
Integrating Climate into Construction Training. We adapted the Climate Fresco for construction trade learners, making global climate issues tangible through sector-specific examples. The inclusive approach connected future roofers, painters, and heating engineers to their role in the ecological transition of the building sector.
ABB: Tailored Sustainability Journey for Product Teams
Tailored Sustainability Journey for Product Teams. We designed a progressive awareness journey for ABB's product team, combining Climate Fresco, 2tonnes simulation, and design fiction workshops. The tailored approach transformed abstract sustainability concepts into concrete actions integrated into design, processes, and customer engagement.
Common questions
Most workshops are designed for groups of 8 to 16 participants, which is the range where group dynamics work best and every participant gets to speak. Some formats (Climate Fresk, 2tonnes) can scale to 50 or more with multiple facilitators running parallel tables. For large events (company-wide days, conferences), Bleen deploys several facilitators simultaneously. Tell us your group size and we adapt the format.
French, English, and Dutch. Most facilitators are bilingual or trilingual. For international teams with mixed language preferences, Bleen can run parallel tables in different languages within the same session. Workshop materials (handouts, slides, debriefs) are available in all three languages. If you need another language, ask: some facilitators also cover German and Spanish.
Yes. Beyond the catalog of 50+ existing formats, Bleen designs custom workshops tailored to your sector, your internal challenges, and your ESG maturity. A custom workshop takes 1 to 6 months to develop, including a briefing session, content design, a pilot run, and final adjustments. Recent examples: a consumption fresco for Pluxee, a water and energy quiz for Air Liquide or even a one health conference for Abbvie.
A workshop is a participatory session (1.5 to 3 hours) where teams learn by doing: manipulating data, solving problems, debating trade-offs. A training is a structured program (half-day to multi-day) with learning objectives, assessments, and sometimes certification. A conference is a keynote-style presentation (45 to 90 minutes) designed to inform and inspire a larger audience. Bleen offers all three formats, and they can be combined in a single event.
Yes, and most clients prefer it. Bleen facilitators travel to your location with all necessary materials. The only requirement is a room large enough for the group, with tables that can be arranged in clusters. For workshops that involve physical materials (the fresques, for example), Bleen brings everything. Remote and hybrid formats are also available for distributed teams, though in-person sessions consistently produce stronger engagement.
For awareness workshops (fresques, collages, quizzes): participants can receive a completion attestation on demand, not a formal certification. For structured training programs (CSRD 101, Climate 101, multi-day courses): Bleen issues a certificate of completion with learning outcomes documented.
