London Stock Exchange Group launches new ESG scores

On March 9, 2026, The London Stock Exchange Group (LSEG) announced that it launched LSEG Sustainability Ratings and Data, a new suite of environmental, social, and governance (ESG) scores and sustainability analytics to help investors evaluate how companies manage material risks and opportunities. The company said the system is designed to support investment decisions, benchmarking, and corporate engagement by providing standardized sustainability data across markets.

Elena Philipova, LSEG’s director of sustainability solutions said, "By uniting 25 years of sustainable finance expertise, with datasets trusted by the global financial industry, we’re giving financial institutions the clarity and confidence to meet regulatory expectations, support transition-aligned capital allocations and build AI-ready ESG workflows.”

The scoring model evaluates companies on a 0-to-5 scale across 12 ESG themes, including climate transition, biodiversity, energy and resource use, labor relations, human rights, board governance, shareholder rights, anti-corruption, and tax transparency. The framework relies on 220 standardized indicators and more than 2,000 underlying ESG data points.

According to the LSEG, the dataset covers more than 16,000 companies and more than one million fixed-income instruments, representing about 99% of the FTSE All-World Index, a global benchmark that tracks large- and mid-cap stocks across developed and emerging markets.

The company said the scoring model uses a rules-based methodology rather than analyst judgment. LSEG said this will make the scores easier to compare and integrate into financial models and automated investment workflows.

The product also includes an optional ESG Scores Plus layer that adds additional data signals, such as corporate controversies, sovereign ESG risk, green revenues, and sustainable finance metrics. LSEG said this will allow users to expand analysis without changing the core ESG score used in financial workflows.

Several organizations publish global sustainability reporting frameworks that guide how companies disclose ESG information. Financial data providers and investors often use these frameworks to build sustainability ratings and analytics tools.

International Sustainability Standards Board (ISSB): Develops global standards for corporate sustainability disclosures as part of the IFRS Foundation’s reporting framework.
Global Reporting Initiative (GRI): Publishes widely used sustainability reporting standards focused on organizations’ environmental and social effects.
Sustainability Accounting Standards Board (SASB): Developed industry-specific disclosure standards focused on financially material sustainability information for investors.
European Sustainability Reporting Standards (ESRS): Define corporate sustainability reporting requirements in the European Union under the Corporate Sustainability Reporting Directive (CSRD).
