Technology in service of people.
Releaf Carbon supports SMEs, mid-caps and large industrial groups in their ecological transition. Rigorous environmental studies, actionable decarbonization plans - no empty slides.
From Reaset to Releaf Carbon.
Our journey: from a carbon-credit marketplace to an independent environmental consultancy.
Reaset is founded
Guillaume and Vincent meet at Centrale Lille and found Reaset, a carbon-credit marketplace. The ambition is already there: building a company with impact.
Releaf Carbon is born
A strategic pivot: Reaset becomes Releaf Carbon, a consultancy specialized in decarbonization and eco-design. A new identity, a clearer vision.
First carbon assessments
First Bilan Carbone® engagements and first collaborations with mid-cap companies in the Hauts-de-France region. Trust takes hold.
LCA & EPD expertise
Launch of our LCA, EPD and FDES offering. Nathan joins the team as eco-design expert partner. The offer is built around two pillars.
The team grows
Arthur, Evane and Corentin are hired. Releaf grows from 3 to 8 employees in one year. A multidisciplinary, committed team.
Launch of our platforms
Release of our real-time carbon management SaaS platform and our e-learning platform to learn how to carry out a carbon assessment. 2026 is a turning point in Releaf Carbon's tech shift.
The next chapter is written with you
Three principles, upheld.
We deliver environmental studies grounded in scientific data, designed to serve a viable decarbonization trajectory. Here are the principles that structure them.
Transparency
No figure published without its assumption. Our reports detail source data, scopes and limitations - so you can challenge our conclusions.
Rigor
Our studies rely on recognized standards (ISO 14040/44, ISO 14067, GHG Protocol, PEF, PEP, FDES). Our SimaPro models are versioned and reviewed.
Collaboration
We train your teams alongside the engagement. The deliverables are yours - no dependency on the firm, no black box.
