ESG scores of the worlds' largest insurance companies 2025, by provider
A comparison of standardized ESG scores of the 27 largest insurance companies in the world shows significant differences between ESG score providers in many cases. The world's largest insurer by market capitalization, UnitedHealth, saw the largest range of scores, with S&P rating the company with the score of 44 out of 100 (indicating the company has a high level of ESG risk), while Sustainalytics awarded the equivalent score of 16.6 out of 100 (indicating a low average level of ESG risk). MSCI was somewhere in the middle, awarding a score which was the equivalent of 64.3. However, there was also some degree of convergence between the three ESG score providers as well. For example, all three companies awarded high ESG scores (indicating low risk) to most of the large European insurers such as Allianz, Munich Re, AXA, and Zurich Insurance Group.
What do ESG scores mean?
Environmental, social, and governance (ESG) scores are a vital investor tool used to assess a company's sustainability and ethical performance. As mentioned briefly above, ESG scores range from 0 to 100, with a score of more than 70 considered good, and a score of less than 50 considered relatively poor. In 2021, a survey was carried out to determine investor satisfaction with the quality of ESG reporting globally. It was found that the largest share of investors reported poor satisfaction with their ESG reporting.
Allianz is one of Europe's leading insurer groups
Among the European insurance companies that were awarded high ESG scores, Allianz was the largest in terms of market capitalization, which amounted to nearly 132.16 billion U.S. dollars as of February 2025. One of the world's leading insurers, Allianz is a German financial services company headquartered in Munich that provides insurance and asset management as its core business products. In 2023, the Allianz Group generated the highest revenues recorded during the period of observation, amounting to a value of over 160 billion euros.
