Multinational companies are operating in a far more environmentally damaging fashion in China than they do at home, according to the Beijing-based Institute of Public & Environmental Affair, which says 90 multinationals that have been found by the environmental protection authorities to have violated water pollution regulations since 2004, Forbes reports.

General Motors, Samsung, Unilever, Pepsi and Yum Brands chains Kentucky Fried Chicken and Pizza Hut are just a few of the companies on the list, according to the article.

“These enterprises are serious towards environmental protection at home but their Chinese subsidiaries here seem to have slackened their efforts,” said the director of the Institute of Public & Environmental Affairs, Ma Jun.

About 30 of these blacklisted international companies have responded to the issue, according to China Daily, but only seven of them said they accept check by a third party, according to Jun.

On the list are only foreign companies involved in water pollution and whose violation of environmental regulations has been made public by the environmental protection department.
