Water security is emerging as one of the defining investment themes of the coming years. Against this backdrop, the European Investment Bank (EIB) hosted a roundtable last week in Luxembourg on water financing models.   Our discussions reinforced a core conviction: water resilience depends not only on technical infrastructure but equally on how we collectively finance and govern water resources. If we fail to act, water insecurity could reduce global GDP by more than 8% by 2050. In Europe, the European Central Bank estimates almost 15% of economic output is at risk due to water scarcity.   The current economic model for water reduces the financial capacity of operators to self-finance the investments needed for the modernization and expansion of infrastructure. Building resilient systems requires robust economic models that blend public resources, private capital and innovative instruments. It’s the only way to close the investment gap and scale up action. It echoes SUEZ's daily reality: designing, building and operating essential infrastructure that serve communities over the long term.    I thank the EIB and the EIB Institute for hosting this initiative, alongside Edouard Perard, PhD, Thierry Déau, Luca Perez, Trine Christiansen, AquaFed, Dominique G. and other attendees for their valuable insights.

Decarbonising the heating and cooling sector is central to achieving the EU’s energy efficiency targets. However, the shift from fossil-fuels to renewables has been slower in this sector, when compared to electricity generation. In 2023, renewables provided 26.2% of final energy consumption in heating and cooling ☀️❄️. The revised Renewable Energy Directive aims to improve on this. It strengthens the heating and cooling target and recognises the sector’s key role in energy system integration.

From Annual to Half-Hourly: A New View of Renewable Electricity Matching New methodology from our partner Matched examines renewable energy supply using half-hourly data instead of traditional annual metrics. With reviewers counting 30+ experts, among which we count our very own Olivier, this paper represents a solid step forward. Analyzing 15 major UK retailers, the methodology reveals matching scores ranging from 56% to 89% on a half-hourly basis. The difference: annual matching compares total yearly renewable certificates to total consumption, while half-hourly matching tracks when renewable generation actually occurs relative to demand patterns. Matched's temporal analysis shows: - Significant variation in renewable delivery timing between retailers with similar annual profiles - Some suppliers achieving 89% half-hourly matching, demonstrating what's achievable - Clear opportunities to understand and optimize renewable procurement strategies Using publicly available data from Ofgem, Elexon, and NESO, Matched has developed an independently verifiable framework for temporal renewable energy assessment in the UK market. As renewable capacity grows, understanding generation timing becomes increasingly important for grid management and energy planning. Half-hourly granularity provides significant additional insight beyond annual renewable percentages. We welcome Matched working hard to bring this enhanced transparency to energy markets.

Shaping a Sustainable Future, Together In this second video dedicated to our Three-Year Sustainability Plan, we dive into the core themes of our commitment: ESG governance, responsible innovation, people development, and impact assessment. Our approach mirrors the structure of a financial plan — with clear goals, KPIs, allocated resources, and risk management — combining economic strategy with environmental and social value. Sustainability for us goes beyond technology: it means concrete care for communities, responsible material choices, and respect for the territories we work in. We also believe in the power of employee well-being, continuous learning, and collective storytelling to foster inclusion and belonging across the organization. All of this works toward a single goal: building a model where environmental sustainability, economic value, and social impact are fully integrated into one measurable and coherent vision. #Sustainability #ESG #ImpactDriven #ResponsibleInnovation #PeopleAndPlanet #SustainableBusiness #CorporateResponsibility

🌍 CSR Changemakers – Maruata DUTREY: Technical Expertise and Civic Engagement for Water Equity Maruata Dutrey, Water Studies Engineer at Saur in South-East France, blends technical expertise with civic engagement to shape the future of water access. Originally from Tahiti, she joined Saur after studying Energy and Environment, specializing in water treatment. Today, she works with public authorities to deliver clean water and protect ecosystems. In 2025, Maruata was selected to join the French Youth Parliament for Water (PFJE) — a national platform that brings together young professionals and students to debate, co-create, and advocate for sustainable water policies, where she contributes a rare mix of technical expertise, on-the-ground experience, island-specific insight, and a pragmatic, solution-driven mindset. Her vision spans local to global: 🔹 Local: secure water amid climate change 🔹 National: ensure equal access, especially overseas 🔹 Global: universal water access without harming ecosystems 📣 More changemakers coming soon — stay tuned. #MissionWater

🌍 Reusing soil to tackle DSOs’ emissions How can grid operators reduce Scope 3 emissions on their work sites? Enedis, which operates over 95% of France’s electricity distribution network, is cutting emissions where it counts most: its work sites. With Scope 3 representing around 70% of its total carbon footprint, Enedis identified soil management as a key lever for action. After successful trials in 2023, the company scaled up the practice of reusing soil onsite. In 2024 alone, it completed 870 low-carbon work sites — each reusing more than 50% of the soil directly onsite. For more examples on how grid operators can cut Scope 3 emissions, download the full Eurelectric study here: https://lnkd.in/eKxe3NMF
