What is it about?
Credit ratings compress many kinds of information into a small number of grades. Using 1,468 Chinese corporate bond records, this study finds that issuer ratings are highly concentrated, while debt ratings preserve more distinctions. Frequent issuance by AAA firms then makes the overall bond-record distribution look compressed again. The apparent climate patterns depend strongly on measurement: a headquarters-weather result disappears when Beijing issuers are excluded, and the emissions-policy result weakens under a narrower definition. Public climate indicators do not consistently improve rating classification beyond financial information. Better credit governance therefore requires transparent links among legal obligors, operating facilities, emitters, guarantors and individual securities.

Why is it important?
A market full of AAA ratings can look more uniform than it really is. In our sample, frequent borrowing by AAA-rated companies made ratings look more concentrated when we counted individual bond records. For investors and regulators looking for signs of climate risk, it matters whether they are comparing companies or the individual bonds those companies issue.
