80% of the funds analyzed in our 2026 Sustainable Finance Barometer rely on proprietary methodologies for their ESG scoring. A telling figure: generic models are no longer enough. ESG teams need to build their own approaches; rigorous, traceable, and tailored to their portfolios. That is precisely why we developed the Methodology Lab. To better understand the principles that guided its design, we asked a few questions to Gabriel Levy, Product Research Analyst at WeeFin. Here is what he had to say: 🔍Choosing the right data: The Methodology Lab allows you to compare different indicators based on objective criteria (coverage, correlations, descriptive statistics) before making a decision. And to test multiple versions of the same model under real conditions. 🧩 Building without coding: A library of operators designed alongside our ESG experts, covering all use cases, from the most common to the most sophisticated. ✅ Validating with rigor: Built-in "expertise checks" to test sector coverage, detect outliers, and analyze geographical or entity-type biases. 📋 Ensuring traceability: Every version is timestamped and assigned to an owner. A complete audit trail to guarantee regulatory compliance. 🤝 Collaborating safely: A granular rights management system to work as a team, duplicate models, and aggregate distinct pillars (E, S, G) into a shared macro-model. 👉 Find Gabriel's full interview in the comments.

The SFDR review process is ongoing. Following the European Commission’s proposals, presented last November, it is now the Parliament’s turn to publish its amendments. In this post, Grégoire Hug, CEO and co-founder of WeeFin, outlines the key changes to keep in mind. 🔍 The WeeFin team will, of course, be closely monitoring the developments leading up to the final text.
More news on the future SFDR! Recently, the European Parliament has published its amendments. The WeeFin team (Louise Piette 🚀 ) took the time to read through them and identify the points of interest for sustainable investors : 1️⃣ Funds that don't qualify for any of the new ESG categories will need to include a statement to that effect in their regulatory documents (notably in their PRIIPS). 2️⃣ PAI reporting: disclosure becomes mandatory for Article 7 and 8 (mandatory PAIs + material ones). Note : for Article 9, the text is unclear : "financial market participants shall choose to comply in full or in part". 3️⃣ The possibility for a fund to automatically meet the 70% threshold by replicating or referencing an EU Climate Transition or Paris-Aligned Benchmark is removed. 4️⃣ For Article 7 and 9, a fund is considered answering the 70% threshold criteria if it invests more than 20% in taxonomy aligned investments (European Commission proposed only 15%) 5️⃣ For Article 8, Funds must now outperform the average ESG rating of their universe or benchmark after eliminating the bottom 20% of lowest-rated securities. 6️⃣ The European Parliament suggests extending the scope of the ESG Ratings Regulation, in order to reinforce minimum standards of quality, transparency and methodological disclosure - a regulatory development to monitor. 7️⃣ SFDR 2.0 will apply 24 months after entry into force, not 12 as initially proposed. These amendments might appear to be nothing more than a technical update. In reality, they could set a real process in motion. Here’s why: First, Funds not aligned with the new ESG categories will be required to state it explicitly. There will therefore be a commercial cost to non-compliance with the new categories: clients will be clearly informed that sustainability is not taken into account, which could prompt them to entrust their investments to other providers. Secondly, for funds that have chosen to align themselves, the rules will be more restrictive (mandatory reporting of PAI, changes to the rules regarding taxonomy alignment, etc.) These changes are moving towards a more comprehensive and precise ESG framework, more in tune with the expectations of the most demanding clients. For asset managers, the revision of the SFDR, which is leading to more sophisticated ESG practices, will be key to winning mandates from institutional investors, as demand for sustainable products shows no sign of slowing down. Happy to discuss with anyone navigating the SFDR 2.0 transition.

🎯 [WEBINAR] Navigating Impact & Transition: LuxFLAG's new labelling standards explained On May 28th at 11:00 AM (CET), join Ahmed Ouamara, CFA, Head of Sustainability Operations at LuxFLAG, and Raphaèle Védy, ESG Expert at WeeFin, for an exclusive session unpacking the challenges, the opportunities, and the bold new frameworks introduced in 2025. 📋 On the agenda: → The future of sustainability labels: How is the rise of European regulation redefining their role and relevance in today's ESG ecosystem? → LuxFLAG's new Impact Label : Launched in December 2025, with two distinct focuses: Climate & Nature and Social. What defines an "impact" fund under this framework? How are mixed-allocation portfolios assessed when they don't reach the 70% threshold on a single pillar? → LuxFLAG's new Transition Label: Also introduced in 2025. What sets a transition fund apart from a traditional ESG-labelled fund? Why can social criteria satisfy the label's requirements? And what data should fund managers prepare when applying? 💡 Why join? Labels are no longer just a mark of quality, they are becoming a strategic necessity. This session will give you the clarity and confidence to design, distribute, or invest in labelled funds, while staying ahead of the regulatory developments shaping tomorrow's market. 📌 Register here: https://lnkd.in/dyQPWdqH

♦️ Our exclusive study on shareholder engagement in the UK is now available to download. It examines the practices of 10 leading financial institutions. What will you learn there? - The commitment is real. All ten institutions are signatories to the UK Stewardship Code and PRI. Most have built dedicated stewardship teams. Collaborative engagement through initiatives like Climate Action 100+ is near-universal. - The culture and the people are there. The engagement is genuinely happening. - Turning individual engagement efforts into systematic, measurable, comparable processes still remains a challenging task. The institutions that invest now in the right tool will be the ones able to demonstrate the real impact of their stewardship, with rigor, and at scale. Want to know more ?
