LSEG Launches New Suite of ESG Scores and Sustainability Analytics to Enhance Transparency for Global Markets

WHY THIS MATTERS: LSEG’s launch of a new, transparent suite of ESG scores marks a strategic response to the acute problem of greenwashing and the increasing regulatory pressure across global financial markets. The broader industry significance lies in the clear differentiation between these scores—which rely on rules-based, transparent methodology—and traditional ESG ratings that often incorporate analyst judgment. This move provides the explainability and consistency demanded by institutional investors. Crucially, the scores are designed to be easily embedded into automated and AI-powered workflows, making them “AI-ready”. This is critical as firms move to integrate sustainability considerations at scale across the entire investment lifecycle. By covering over 90% of global market capitalization and aligning with major frameworks like ISSB and ESRS, LSEG is building an essential, standardized data layer for transition-aligned capital allocation.

LSEG today announces the launch of a new suite of ESG scores, and sustainability analytics designed to provide actionable insights to global financial markets through enhanced transparency, comparability and analytical value.

Financial institutions are operating under increasing regulatory scrutiny, with obligations to safeguard against greenwashing, and a growing need to embed ESG considerations into automated and AI-powered workflows. To support this, LSEG’s new ESG scores are built on a research driven methodology aligned with leading global sustainability frameworks and regulations such as ISSB, GRI, SASB and ESRS. As scores, they rely on transparent, rules based methodology and inputs and do no incorporate analyst judgement, which clearly differentiates them from ESG ratings.

The enhanced model incorporates a curated set of 220 standardised indicators, and a sustainability-first materiality matrix combining a redesigned industry classification with a double materiality approach at a business segment level. The transparent scores, from a scale of 0 (not aware) to 5 (leading), are designed to provide clarity and consistency for a wide range of financial workflows.

LSEG’s new ESG scores measure how effectively companies manage material ESG risks and opportunities across 12 Themes, aggregated into three Pillars and an Overall ESG Score. The new scoring framework innovates by introducing threshold-based scoring levels, capping metrics and performance analytics, ensuring companies are rewarded for implementing strategic ESG initiatives and demonstrating verifiable sustainability progress.

For deeper insight, Sustainability Ratings and Data also includes a ‘Plus’1 layer that incorporates controversies, sovereign ESG risk and positive environmental impact signals such as green revenues and sustainable financing. These overlays allow users to extend their analysis without changing their core ESG framework.

The new ESG scores and sustainability analytics are available across multiple LSEG platforms, including its flagship LSEG Workspace, a workflow-native platform powered by trusted LSEG data and analytics, integrated directly into financial professionals’ workflows.

Elena Philipova, Director, Sustainability Solutions at LSEG, comments: “Our customers are consistently looking for sustainability insights they can explain, justify and integrate across the investment, lending and advisory lifecycle. 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.”

LSEG maintains over 2,000 ESG data points in line with corporate reporting cycles across 16,000 companies which issue over 1 million fixed income instruments. This represents over 90% of global market capitalisation, covering 99% of the FTSE All World index.  

FF NEWS TAKE: This launch decisively moves the needle by providing a structured, explainable dataset necessary to satisfy complex EU regulations and build high-confidence sustainable finance products. The transparent, rules-based nature eliminates a major source of skepticism surrounding traditional ESG scores. We should watch closely whether LSEG’s model—which rewards verifiable progress via threshold-based scoring—becomes the market standard for automated ESG workflows. The next step is observing how rapidly financial institutions migrate their existing systems onto the LSEG Workspace platform to leverage this AI-ready data layer.
