Context & Environment

To meet its ambitious objectives of the energy transition towards electricity and renewable energies, TotalEnergies' entity, OneTech, combines all the corporate departments providing technical support to our operations and R&D (Exploration & Production, Refining & Chemical, Marketing & Services and Gas, Renewables & Power). With a 3,400-strong workforce, OneTech will be split into three hubs: an industrial hub supporting the Company's expansion in gas, renewables, electricity and carbon emissions reduction; a research & development hub regrouping all TotalEnergies' research activities to anticipate the Company's transformation, by giving priority to the low-carbon mix; and a support hub (HR and finance)

By integrating all the Company's technical and R&D expertise in a single entity, OneTech becomes one of the pillars of TotalEnergies' transformation into a multi-energy company.
