Establishing bold transition strategies

H2D is a company dedicated to providing organizations with systemic support for their environmental transition policies.


Implementing ambitious environmental objectives requires a systemic analysis of past and future impacts. To this end, we have established a triptych of services designed to meet this challenge.

These include transition strategy consulting, multi-criteria environmental assessments and research and development.

Transition strategy consulting

Environmental audits

Research & Development

Aware that our services require the sharing of confidential data - both within your organisation and sometimes with your suppliers - we have established some of the strictest processes in this area: we only use secure software, are signatories of a confidentiality charter and give this issue central consideration when establishing our contracts.
