When a company takes out environmental risk insurance, can it improve its performance on environment, society and governance? A Chinese study says yes. Using panel data from over 2,000 A‑share listed firms on the Shanghai and Shenzhen exchanges between 2009 and 2022, researchers compared firms that joined a pilot environmental pollution liability insurance scheme with those that did not. A multi‑period difference‑in‑differences approach isolated the policy’s effect, controlling for other factors.
The findings reveal that green insurance raised overall ESG scores, especially in the environmental and social dimensions. High‑tech firms, heavily polluting industries and companies in the most industrialised regions saw the strongest benefits. Channel analysis points to three drivers: firms increased clean‑technology investment, faced stricter external oversight and upgraded both internal and external governance.
In short, an insurance policy can act as a governance tool that nudges companies toward greater responsibility. The research provides firm‑level evidence that financial instruments can spur sustainable change and offers guidance for policymakers seeking to refine green finance mechanisms.
