Our expertise

Two pillars for a sustainable and resilient strategy

Sustainability and digital resilience challenges are inseparable. LUTECIUM structures its offering around two complementary pillars, delivered through strategic advisory, operational support and training programmes.

Pillar 1

Low-Carbon Strategy & Transition Planning

Measure, reduce, transform: from carbon data to a validated decarbonation roadmap.


Carbon Measurement & Reporting

Comprehensive carbon footprints (GHG Protocol, Bilan Carbone©), Life Cycle Assessments (LCA) tailored to digital organisations, and reporting aligned with CSRD/ESRS E1, CDP, BEGES and SBTi-validated trajectories.

GHG Protocol LCA SBTi CDP

Responsible Digital & Digital Sobriety

Responsible digital strategies: usage rationalisation, hardware lifecycle extension, eco-design of digital services, responsible procurement and low-carbon hosting.

Responsible digital Digital sobriety Eco-design

Frugal AI & Responsible Governance

Integrating frugal AI principles into projects: architecture choices, data sobriety, usage governance and environmental reporting for AI systems.

Frugal AI AI Governance
Pillar 2

Risk Management: Energy-Climate & Digital Sovereignty

Anticipate, map, strengthen: resilience as a competitive advantage.


Energy-Climate Risks & CSRD Compliance

Scenario-based Energy-Climate risk analyses (TCFD, OCARA©), double materiality assessments, ESRS indicators and CSRD compliance — covering physical risks (extreme events, water stress) and transition risks (carbon regulations, asset depreciation), through to non-financial declarations and audit preparation.

Energy-Climate Risks CSRD TCFD Double materiality

Digital Sovereignty & Resilience

Audit and transformation of enterprise architecture (TOGAF©) to strengthen digital sovereignty, strategic digital autonomy and digital resilience against external shocks — supply disruptions, cyberattacks, regulatory changes.
