Biography

An engineer, entrepreneur and speaker, Pascale Lefebure puts science at the service of one conviction: when it comes to the major environmental challenges, the solutions often already exist — but you still need to know how to identify, understand and apply them.

A solutions-driven scientist

An engineer in biotechnology and the environment, Pascale Lefebure started out in pollution-control R&D before spending several years working for the French Ministries of Defence and the Interior on the assessment of emerging technologies. There she acquired a rare breadth of knowledge, at the crossroads of science, innovation and foresight.

From Earth to space

Her career then took her to the United States, where she worked for the United Nations on the 2030 Agenda and the Sustainable Development Goals. Trained in aerospace project management at ISAE-SUPAERO, she joined the space industry, worked on life sciences in microgravity and became a mentor for UNOOSA’s Space4Women programme.

Turning ecology into action

Back in France, she develops projects around sufficiency, the circular economy and resource preservation. In particular, she created the Water Performance Diagnostic (Diagnostic de Performance Eau), a pioneering approach that measures a building’s consumption and identifies achievable savings.

A speaker who gets out into the field

Pascale Lefebure does not simply talk about the transition: she seeks out innovations, tests them and explains them. Through her Sustainability Mystery channel and the content she has produced, in particular around ChangeNOW, she shows how technology, science and new practices can make the transition more concrete, accessible and desirable.

Solutions can be simple and accessible.

Workshops

Water Diagnostics and Performance

  • The Water Performance Diagnostic seminar takes place in a context where repeated droughts, declining groundwater levels, and usage restrictions imposed by authorities highlight the urgency of more rigorous water resource management. Participants discover the operational, financial, and strategic challenges associated with water scarcity, as well as the cross-sectional benefits linked to more sustainable consumption.
  • The training emphasizes the importance of combining responsible behaviors with technical innovations. It shows that while raising user awareness is useful, the real impact primarily relies on deploying sustainable water-saving equipment capable of reducing consumption without relying on changes in habits. This structural approach allows for long-term water management and anticipates future risks.
  • During the two half-days, participants learn to conduct a comprehensive water performance diagnostic of a building. They are trained to collect relevant data, analyze consumption, identify critical points, and select appropriate equipment from a validated selection. Practical work, based on real cases, allows for the immediate application of the methods discussed, particularly the calculation of the return on investment for the various solutions.
  • The seminar also offers a strategic aspect, focused on planning and prioritizing actions. Participants build a structured deployment plan using provided tools such as Gantt charts. They also learn to detect pitfalls, avoid problem transfers, and optimize the overall profitability of their efforts to improve the water performance of the building.
  • Finally, the training includes a module dedicated to communication, essential for promoting the efforts made to stakeholders. Trainees work on designing clear and impactful messages, accompanied by suitable materials. The entire seminar is based on active pedagogy, alternating theoretical contributions, case studies, and collective discussions, with the aim of equipping professionals to become autonomous and credible actors in the transition towards water sobriety.
