ESG-independent wealth management in Switzerland is at a crossroads. On the one hand, global disclosure standards such as the ISSB’s IFRS S1 and IFRS S2 are driving consistency. On the other hand, sustainable fund flows remain volatile, and policy uncertainty clouds the narrative. Meanwhile, Asia—particularly China and Hong Kong—is accelerating mandatory disclosure and expanding carbon markets, setting new benchmarks for transparency.
1️⃣ Where ESG Stands Now: Substance and Setbacks
Global ESG flows show mixed momentum. FT and Reuters both reported significant outflows in US sustainable funds through 2024 and early 2025, while Europe maintained moderate inflows. Morningstar’s Q3 2025 data confirms that ESG investing remains cyclical rather than secular.
Regulatory clarity, however, is improving. The ISSB’s unified disclosure framework, effective from 1 January 2024, establishes a baseline for corporate sustainability data. Yet debates in Europe—especially on whether specific industries can be labelled “sustainable”—illustrate ongoing inconsistency within ESG taxonomies. Reuters, Aug 2025 · EU Taxonomy
2️⃣ Asia’s Momentum: Disclosure First, Capital Follows
Hong Kong has aligned its listing rules with ISSB climate standards, requiring listed companies to disclose in line with the HKEX 2024 climate disclosure regimes. Mainland China is expanding its national emissions trading system (ETS) to include steel, aluminium, and cement—covering more emissions than any other carbon market worldwide. World Bank 2024
Implication: While Western fund flows fluctuate, Asia’s “rules-first” model may quietly set the global ESG data baseline. In practice, this means Swiss independent wealth managers will increasingly rely on Asian disclosure data for cross-comparability and risk calibration.
3️⃣ Independent Wealth Managers: Pragmatic ESG Integration
- Adopt standards, not slogans: Integrate IFRS S1/S2 data layers, even if they are not yet mandatory under Swiss regulation.
- Keep double materiality separate: Present “impact” vs “financial materiality” side by side rather than blending scores.
- Fact-check fund methodologies: Avoid automatic labels; verify how each fund defines its ESG universe, especially under evolving EU guidance.
- Include Asia’s disclosures: Add HKEX/Shanghai metrics and China ETS data into consolidated reporting dashboards.
4️⃣ What Clients Should Expect in 2026
- Improved comparability as ISSB standards spread, reducing greenwashing risk.
- More stable fixed income ESG funds—bond mandates tend to outperform equity ESG allocations during volatile periods.
- Asia becomes a data hub—mandatory climate reporting in Hong Kong and mainland China drives global portfolio alignment.
5️⃣ ESG Portfolio Playbook for UHNWIs
- Start with exposure mapping: Identify top ESG drivers (carbon, controversy, product governance) within existing portfolios.
- Prefer audited data: Use ISSB-aligned or exchange-reviewed disclosures.
- Use fixed income for clarity: Green and transition bonds provide measurable transparency into the use of proceeds.
- Monitor policy drift: Track taxonomy redefinitions and shifts in investor sentiment.

FAQ
Has ESG “broken through” in 2026?
Not fully. Fund flows are inconsistent and politics distort labelling, yet disclosure standards (ISSB) and Asia’s mandatory reporting create lasting structural change. FT/Morningstar 2025
Why mention Asia?
Because Hong Kong’s ISSB-aligned climate disclosures and China’s expanding ETS create the world’s largest pool of standardised ESG data. HKEX 2024 · ICAP 2025
How should Swiss independent wealth managers respond?
Adopt ISSB-ready reporting, verify fund methodologies, map Asia disclosures into dashboards, and separate client values from performance analytics.
Is defence part of ESG?
Definitions vary and remain debated within EU sustainable finance circles, which impacts investor perception and product labelling. Reuters 2025 · EU Taxonomy
