The world’s largest carbon credit registry has rejected four projects that won business from Apple and other multinationals. The decision, which comes a little over two months after a similar decision on a different project, threatens the status of any emissions claims that might have been made using the credits.

The projects were rejected by Verra late last week due to “serious allegations regarding the authenticity of government approval documents,” the registry said. 

A total of 4.4 million credits were issued between 2021 and 2023 to the project developer, Guizhou Baiheng Fertiliser Company, which claimed to remove carbon by planting trees on previously unforested land in Guizhou Province, in southwest China.

Around 40 companies then purchased and retired credits from the projects, according to data from OffsetsDB, an open-source carbon credit database.

The list includes five that retired more than 100,000 credits: Takeda, a Japanese pharmaceutical company (660,000 credits); Apple (630,000); PetroChina International (510,000); Shell (340,000); and Continental (200,000), a German automotive parts maker. Another 2.5 million were retired by companies that remained anonymous.

Carbon neutral claims

Credits are often retired to satisfy claims that a product or company is carbon neutral. Neither Takeda, Apple, PetroChina nor Shell would say if the Guizhou credits were used in this way. Continental’s credits were purchased in connection with a project that was put on hold for reasons unrelated to the Verra finding, a spokesperson said.

If the credits were used in connection with emissions claims, the status of those claims is now uncertain. Under Verra rules, the project developer is required to purchase and retire 4.4 million credits as compensation. But the average price of a credit on the voluntary carbon market was a little over $6 in 2024, and it is unclear whether Verra can compel the developer to invest the millions of dollars that might be required to make good on the rejected projects. A Verra spokesperson said the registry had contacted the developer and was awaiting a response.

An Apple spokesperson told Trellis that the company had contacted Verra after learning of the rejected projects to understand the registry’s process for seeking replacement credits, which it would monitor closely. 

A Shell spokesperson said: “We were disappointed to learn of the issues Verra identif
