The survey, conducted by more than 30 environmental NGOs, ranks the U.S. tech giant last in a list of similar multinational technology manufacturers.
Nokia, Sony, Ericsson and LG were also singled out for poor environmental and social practices. On the other hand, the report extolled Hewlett-Packard, Vodafone, Samsung, Toshiba, Sharp, Hitachi, BT and Alcatel-Lucent for improving manufacturing standards.
“Apple has broken its promise on three aspects of supply-chain social responsibilities,” said the report.
“On Apple’s supply chain, some workers were poisoned and disabled, neighborhoods and communities were polluted while there were severe infringement of workers’ rights, interest and dignity,” the report said.
The report comes as the Cupertino, Calif.-based company begins to open stores in China. Last week Apple raked in $2.6 billion – about 10 percent of its total revenue – from China, Hong Kong and Taiwan, The Associated Press reports.
The report was posted Thursday on the website of the independent Beijing-based organization the Institute of Public and Environmental Affairs.
