Cases
Every case here started the same way: a company with an ESG question and no clear answer. Here's what we built together.

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.
Pluxee: Designing High-Impact Biodiversity Contribution
Designing High-Impact, Measurable Biodiversity Contribution. Rather than buying conventional offsets, Pluxee wanted to invest in credible contribution projects whose impact could actually be measured and claimed. We worked with expert partners to curate a tailored shortlist of innovative biodiversity projects (from reforestation to soil regeneration) assessed each on credibility, traceability and long-term impact, and built the whole approach around MRV (Monitoring, Reporting, Verification), so every claim rests on evidence rather than assertion.
Pluxee: Carbon Footprint & SBTi Climate Strategy
Revising and Certifying a Mature Carbon Footprint. Pluxee wanted to consolidate an already-established carbon footprint and SBTi-approved trajectory to meet GHG Protocol and EcoVadis expectations and reinforce stakeholder credibility. We challenged and fine-tuned the existing GHG inventory for EcoVadis submission, stress-tested the SBTi trajectory, and coordinated a third-party certification to differentiate the brand.
Octa+: Sustainability Strategy with a CSRD Double Materiality Analysis
Structuring Octa+'s Sustainability Strategy with a CSRD Double Materiality Analysis.
Octa+, a Belgian energy and mobility supplier, wanted to prioritise its most strategic sustainability issues and meet CSRD requirements. We ran a 2tonnes workshop and CSRD training for the Exco, modelled the value chain, and consulted internal and external stakeholders to build a double materiality matrix, followed by an ESRS gap analysis with recommendations.
Elia: Selecting a CSRD Reporting Platform for Grid Operations
Selecting a CSRD Reporting Platform for Grid Operations. Elia ran a structured selection process to find a reporting tool that fits its CSRD obligations. We led the scoping, benchmark, RFP, and vendor evaluation across five phases, closing with a shortlist ready for contracting and a digitisation roadmap for CSRD datapoints.
Deltrian: From Carbon Data to Climate Action
From Carbon Data to Climate Action. We deepened Deltrian's existing carbon footprint analysis, transforming raw data into actionable climate strategy. Through rigorous verification and strategic ideation workshops, we helped prioritize reduction levers and create a clear roadmap integrating climate goals into their cooperation projects.
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.
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 consultation revealed critical nuances and sensitivities that shaped their strategic priorities and communication approach.
Trias & Broederlijk Delen: Mainstreaming Climate into Development Cooperation
Mainstreaming Climate into Development Cooperation. For two international development NGOs, we designed a climate mainstreaming strategy that goes beyond measurement. From benchmarking 30+ carbon tools to facilitating change management workshops, we helped integrate climate considerations into every dimension of their cooperation work.
Sioen: First Carbon Footprint for Sector-Wide Knowledge Sharing
First Carbon Footprint for Sector-Wide Knowledge Sharing. Working with Circular Wallonia, we helped Sioen complete their first comprehensive carbon footprint assessment and build internal capacity on emission reduction. The project delivered a transparent methodology designed for sector-wide knowledge sharing, complete with a prioritized decarbonization roadmap.

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.
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.
Equans: Sustainable IT Strategy

The co-creation process generated actionable solutions addressing systemic challenges beyond traditional job placement.
Cofinimmo: Portfolio-wide Biodiversity Strategy
Portfolio-wide Biodiversity Strategy. We analyzed 358 healthcare properties across 9 countries, identifying biodiversity risks and opportunities at scale. Combining top-down assessment with 18 detailed site visits, we delivered quick-win and best-in-class action plans that meet CSRD requirements while protecting ecosystems.
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.
SNCB: From GRI Baseline to CSRD-Ready Reporting
From GRI Baseline to CSRD-Ready Reporting. SNCB, as a public rail operator, needed a non-financial report aligned with GRI and a clear path to CSRD, Taxonomy, and CSDDD compliance.
