Our services
Sustainability expertise measured in projects delivered, not years of theory.
Long Game
Sustainability covers a wide spectrum: climate, biodiversity, water, waste, circular economy, responsible sourcing. Most organizations need deep expertise on one of these at a time. A Bleen sustainability expert focuses on your specific environmental challenge, applies the relevant methodology, and delivers results your team can act on.
Key Takeaways
- Climate expertise: carbon footprints (scopes 1-3), SBTi targets, decarbonization pathways, internal carbon pricing
- Biodiversity: ecological diagnostics, TNFD assessments, nature-positive strategies, site-level action plans
- Circular economy: material flow analysis, eco-design reviews, waste reduction strategies, circular KPIs
- Water stewardship: water risk mapping, consumption reduction plans, watershed-level impact assessments
- Cross-sector experience across manufacturing, real estate, energy, food, and public sector
What a sustainability expert covers
Carbon and climate. Bilan Carbone (scopes 1, 2, 3), GHG Protocol assessments, SBTi target setting and validation, decarbonization action plans with costed measures, internal carbon pricing design. The expert handles the full technical scope from data collection to target submission.
Biodiversity. Ecological diagnostics at site level, TNFD-aligned assessments, dependency and impact mapping, nature-positive strategy design, restoration planning. The expert combines field knowledge with reporting frameworks.
Circular economy. Material flow analysis across your value chain, eco-design assessment of products or packaging, reverse logistics evaluation, circular economy KPI design. The expert maps where materials leak and where circular opportunities exist.
Water. Water risk mapping using WRI Aqueduct and local data, consumption audits, reduction plans, and watershed-level impact assessment for companies with significant water footprints.
Integration. Environmental topics rarely exist in isolation. A carbon expert who understands biodiversity trade-offs, or a circular economy specialist who can quantify carbon implications, produces better recommendations than a single-domain view.
Why an external sustainability expert
Methodology matters. A Bilan Carbone done wrong is worse than no Bilan Carbone: it sets false baselines and misdirects investment. An expert with 50+ assessments behind them applies the methodology correctly the first time.
Sector context. A manufacturing company's decarbonization pathway looks nothing like a real estate portfolio's. A Bleen expert brings sector-specific benchmarks, best practices, and realistic targets.
Regulatory alignment. CSRD, SBTi, TNFD, EU Taxonomy: each framework has specific technical requirements for environmental disclosures. The expert builds compliance into the assessment from the start.
Independent assessment. An external expert produces findings that your board, investors, and auditors trust more than an internal estimate.
How the engagement works
Scoping (1 week). Defining the perimeter, data requirements, deliverable format, and timeline. Written scope document before any work begins.
Data and fieldwork (2 to 8 weeks). Data collection, site visits if required, interviews with operational teams. The expert flags gaps early and proposes estimation methods where direct data isn't available.
Analysis and deliverable (1 to 3 weeks). Results, recommendations, and the deliverable agreed in the scope. Presentation to your team or board included.
Handover. Methodology transfer, tools, templates. Your team can maintain and update the work in subsequent cycles.
They transformed with Bleen
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.
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.
Balteau: Building an ESG Culture from the Ground Up
Building an ESG Culture from the Ground Up. We partnered with Balteau to transform sustainability from ambition to action. Through materiality analysis, eco-team activation, and comprehensive policy development, we helped embed ESG into their business strategy while mobilizing employees as internal champions of change.
