The Monetary Authority of Singapore, the People's Bank of China and the European Commission's Directorate-General for Financial Stability, Financial Services and Capital Markets Union jointly published the Multi-Jurisdiction Common Ground Taxonomy in November 2024 at the COP29 climate summit. The taxonomy, referred to as the M-CGT, maps the green activities eligible under each of the three jurisdictions' existing classification systems and identifies the areas of common ground across all three frameworks simultaneously, providing the market with a practical cross-border reference point.

The release marks a significant step in the effort to reduce fragmentation in global sustainable finance. By showing where China's green standards, the EU Taxonomy for Sustainable Activities and Singapore's green finance frameworks converge, the M-CGT creates a practical tool for issuers and investors seeking to deploy capital across these major economic zones without navigating three separate and often inconsistent sets of classification rules.

REDUCING BARRIERS FOR CROSS-BORDER CAPITAL

A persistent obstacle to scaling green finance has been the patchwork of national and regional classification systems, each with its own criteria, thresholds and sector coverage. An instrument labelled green under one framework may not qualify under another, creating compliance complexity and deterring cross-border distribution. The M-CGT directly addresses this problem by providing a validated common layer that issuers can reference when marketing instruments to investors across Singapore, China and the European Union simultaneously.

Under the arrangement, green bonds and green funds structured in alignment with the M-CGT can be distributed across all three economic zones. This expands the potential investor base for qualifying instruments and, in principle, lowers the cost of green capital by broadening demand. For Asian issuers accessing European institutional markets, and for EU issuers targeting Singapore's growing sustainable finance investor community, the taxonomy provides a meaningful reduction in the cross-border friction that has historically limited capital flows.

The MAS, PBoC and EU DG FISMA have been engaged in comparative taxonomy work for several years, building the bilateral and trilateral mapping exercises that formed the foundation for the M-CGT. The choice of COP29 as the venue for the publication was deliberate, signalling to governments and market participants that the three jurisdictions regard taxonomy harmonisation as a geopolitically significant contribution to the global transition finance agenda, rather than merely a technical regulatory exercise.

IMPLICATIONS FOR GREEN BOND MARKETS

For the green bond market, the M-CGT's arrival coincides with a period of rapid growth and intensifying scrutiny of greenwashing risks. Investors and regulators have become increasingly demanding about the rigour of green labels, and a multilateral taxonomy backed by major central banks and the European Commission provides a higher-quality benchmark than many issuer-level frameworks. Instruments aligned with the M-CGT will carry an implicit endorsement from three of the world's most consequential financial regulatory authorities.

The taxonomy's initial coverage focuses on the activity classifications where Chinese, EU and Singapore definitions overlap most clearly. Further iterations are expected to address areas where the three frameworks currently diverge, including contentious topics that have complicated multilateral taxonomy discussions elsewhere. The progress made in identifying common ground nonetheless represents a concrete advance in the long-running effort to create a more coherent global green finance architecture, and builds momentum for broader multilateral taxonomy cooperation ahead of future international climate policy milestones.
