Today, access to reliable data is essential to make informed investment decisions that align with environmental and social goals. Investors are increasingly demanding clear evidence of the real-world environmental and social impact of their investments. At the same time, issuers are facing rising demand for sustainable financing, and the need to fund their transition through capital markets.

As the issuance of sustainable bonds grows, so does the urgency to close the persistent data gap relating to these bonds across both developed and emerging markets. Structured, reliable and comparable data builds trust and credibility in sustainable finance by enabling investors to assess the environmental and social impact of their investments, ensuring intended outcomes are met and ultimately attracting capital to support long-term, impactful development.

23,000+ GSSS bonds from over 4,000 issuers worldwide

To meet the growing demand for sustainable bond data, the Luxembourg Stock Exchange (LuxSE) launched the LGX DataHub in September 2020 – a database providing structured sustainability-related data points on sustainable bonds.

Today, the LGX DataHub includes over 200 data points on more than 23,000 green, social, sustainability and sustainability-linked (GSSS) bonds from over 4,000 issuers worldwide – centralising close to the entire universe of GSSS bonds in one database.

New advanced portfolio reporting feature

To mark its fifth anniversary in September 2025, a new advanced portfolio reporting feature was launched on the LGX DataHub, designed to provide deeper insight into sustainable bond portfolios. Building on existing functionalities, this enhancement covers a wider set of sustainability indicators including alignment with standards, allocation by project category and by geographical region, SDG contributions, impact metrics, EU Taxonomy alignment and the status of sustainability-linked bonds (SLBs).

Users can upload their portfolios directly through the platform and automatically generate an Excel report containing pre-formatted charts, tables and underlying bond-level data. This new feature also allows for additional preferences, such as whether to include estimated figures for bonds without post-issuance reports, with all estimated data clearly flagged throughout the output.

EU Taxonomy alignment data

The LGX DataHub enables market participants to prepare their regulatory reporting. For example, EU Taxonomy alignment data available in the LGX DataHub supports credit institutions in scope of the Corporate Sustainability Reporting Directive (CSRD) in calculating the specific contribution of the green bonds that they hold to their Green Asset Ratio (GAR). It also enables fund managers to better understand what EU environmental objectives the green bonds in their portfolios are contributing to, and in what proportion.

Empowering investment banks and asset managers with real-time insights

By tracking selected instruments, the Watchlist feature enables users to stay effortlessly informed about the latest developments in their sustainable bond portfolios, and receive instant notifications whenever a bond is covered by a new post-issuance report. The tool also alerts users when an SLB reaches or misses its target, allowing investors to closely monitor issuer commitments and make more informed, data-driven decisions.

What's more, it allows users to compare the green and societal impact of different investment opportunities and assess the quality of the reporting provided by issuers more effectively. On a more detailed level, investors and asset managers can monitor Key Performance Indicators (KPIs) and Sustainability Performance Targets (SPTs) for SLBs.

Trusted by ICMA and the OECD

As the LGX DataHub continues to broaden its coverage, its uptake has grown among major actors in the capital markets ecosystem and beyond. In May 2023, the International Capital Market Association (ICMA) unveiled its new sustainable bond database, entirely fed and powered by the data available on the LGX DataHub. The Organisation for Economic Co-operation and Development (OECD) is also among the database's users, having published several studies drawing on LGX DataHub data – including a 2024 report examining key developments, challenges and opportunities in the SLB market.

Advancing sustainable finance calls for a shared commitment, and as we strive towards global sustainability objectives, clear, consistent and reliable data on sustainable bonds is – and will remain – crucial for driving private investment towards sustainable development.
