The London Stock Exchange Group has launched a new Sustainability Ratings and Data suite, providing investors and financial institutions with enhanced tools to analyse corporate environmental, social and governance (ESG) performance.
The new platform introduces a comprehensive set of ESG scores and sustainability analytics, designed to help market participants measure how effectively companies manage sustainability risks and opportunities. The initiative aims to improve transparency and comparability in ESG assessments while supporting capital allocation decisions and regulatory reporting.
As sustainable finance continues to move into the regulatory mainstream, demand for reliable ESG data has surged. Financial institutions increasingly rely on such information to assess long-term risk exposure, meet disclosure obligations and align investment strategies with global climate and sustainability targets.
A New Framework for ESG Measurement
At the core of the new solution is a rules-based ESG scoring framework that evaluates companies across a structured set of sustainability indicators.
The system incorporates 220 standardised indicators and draws on more than 2,000 underlying data points, providing coverage of over 16,000 companies and more than one million fixed-income instruments worldwide.
Rather than relying on analyst judgement, the methodology uses transparent data inputs and predefined rules to generate ESG scores. This approach is intended to reduce subjectivity and address long-standing criticism that ESG ratings often lack consistency between providers.
Companies are scored on a 0–5 scale, where:
- 0 indicates minimal awareness or performance on ESG issues
- 5 represents leading sustainability practices within an industry
The scoring system evaluates performance across 12 key themes, including:
- Climate transition
- Energy and resource use
- Biodiversity
- Water management
- Waste and pollution
- Labour relations and workplace safety
- Human rights and community impact
- Corporate governance and anti-corruption
- Tax transparency and shareholder rights
These themes are aggregated into three broader pillars—environmental, social and governance—alongside an overall ESG score.
Designed for the Era of Sustainable Finance Regulation

The launch comes at a time when financial institutions face growing pressure to integrate sustainability considerations into decision-making.
Regulatory frameworks around the world—including the International Sustainability Standards Board, Global Reporting Initiative, Sustainability Accounting Standards Board and the EU’s European Sustainability Reporting Standards—are rapidly expanding requirements for corporate disclosure and investor transparency.
LSEG said the new scoring model is aligned with these global frameworks, enabling investors to incorporate sustainability data directly into portfolio construction, lending decisions and advisory workflows.
The data is integrated into LSEG Workspace, the company’s flagship financial analytics platform used by banks, asset managers and institutional investors.
Introducing “ESG Scores Plus”
In addition to the core scoring framework, the new suite includes a supplementary analytical layer called ESG Scores Plus.
This additional module expands the analysis beyond traditional ESG metrics by incorporating factors such as:
- Corporate controversies and governance issues
- Sovereign ESG risk exposure
- Positive environmental signals such as green revenues and sustainable financing activity
These overlays allow investors to evaluate both risk exposure and positive sustainability impact, providing a more nuanced view of corporate ESG performance.
Building Transparency in ESG Data
ESG data has become one of the fastest-growing areas of financial analytics, but it has also faced criticism for inconsistent methodologies and opaque scoring systems.
LSEG’s new framework seeks to address these concerns through a transparent, rules-based methodology, ensuring that users can clearly understand how scores are calculated.
According to Elena Philipova, Director of Sustainability Solutions at LSEG, investors increasingly need sustainability insights that can be integrated directly into financial workflows.
Financial institutions want ESG insights they can explain and justify across the investment lifecycle.
The new platform draws on more than 25 years of sustainable finance expertise from LSEG and its subsidiary FTSE Russell.
The Bigger Picture
The launch highlights the growing importance of ESG data infrastructure within global capital markets.
As investors increasingly factor sustainability risks into valuations and regulatory scrutiny intensifies around greenwashing, reliable ESG metrics are becoming a fundamental component of financial analysis.
Platforms like LSEG’s Sustainability Ratings and Data suite aim to bridge the gap between corporate sustainability reporting and real-world investment decisions. By providing standardised and transparent analytics, the initiative could help accelerate the integration of sustainability considerations into mainstream finance.
In a market where trillions of dollars are now tied to ESG-aligned strategies, the ability to measure sustainability performance with clarity and consistency may become one of the defining capabilities of the modern financial system.
