LSEG picked up four prizes this year at Environmental Finance’s Sustainable Investment Awards.

As part of its entry for Stock exchange of the year, the London Stock Exchange pointed to its “comprehensive, global, multi-asset, class-sustainable finance offering”, which it said supports those looking to raise or deploy capital for sustainability projects while giving access to London’s investor base.

Key to its application was the Green Economy Mark, which highlights London-listed funds and companies that derive 50% or more of their revenues from activities contributing to the global green economy. The Green Economy Mark equity issuers have a combined market capitalisation of £192.4 billion.¹In fixed income markets, the London Stock Exchange’s Sustainable Bond Market has established itself as a global hub for sustainable debt. Over 190 entities have placed 993 issuances, raising almost £374 billion since its inception.

The firm won the prize for Thought leadership paper/research on sustainable investing - Global for its LSEG COP30 Net Zero Atlas, which provides investors with a comprehensive assessment of transition and physical-climate risk across G20 economies.

The judges praised the paper for its "comprehensive comparative information across many global risk factors and geographies", adding that it is "excellent" for providing a "concise global overview".

The firm’s third award, Data initiative of the year, was given for its LSEG Sustainability & Ratings Data, which looks to standardise the data used within the ESG marketplace, closing gaps and improving comparability.

The judges for this award said that the firm had made a great start at standardising the link between key global ESG factors and the ability to assess the ratings across various companies.

The fourth prize for the firm went to its FTSE Russell business, which won the Climate index provider of the year.

The firm scored highly with the judges due to its successful translation of the sovereign-level climate transition assessment into an investable, rules-based benchmark. The FTSE Climate Collective Transition EMU Broad Government Bond Index addresses a long-standing gap in climate indexing for government bonds. A core element of this approach was the use of the investor-led Assessing Sovereign Climate-related Opportunities and Risks (ASCOR) framework, which is designed around publicly available, easily interpretable, and comparable data.

In assessing the award, the judges said that FTSE Russell’s work demonstrates end‑to‑end excellence, from methodology and integrity to live market implementation, and shows how climate transition data can directly influence capital allocation in core sovereign portfolios.

Crucially, the judges felt that the application to sovereign bonds through the ASCOR framework was transparent and derived from academic rigor. They also felt that the inclusion of a credit threshold is a practical step to making an investable index, as evidenced by the Robeco Climate Euro Government Bonds ETF.

 In short, the judges highlighted that FTSE Russell has developed a practical product that is grounded in academic research.
