The Center for Biological Diversity says that it filed suit challenging the city of Perris’s approval of the Perris Marketplace, a 520,000-square-foot, big-box retail development that would include a 24-hour Wal-Mart Supercenter and generate, according to CBD, close to 40,000 daily vehicle trips.

The lawsuit challenges the project’s failure to consider measures to reduce greenhouse gas emissions that cause global warming.

“The city refused to meaningfully address the greenhouse gas emissions generated by the Wal-Mart Supercenter,” said Center staff attorney Matt Vespa. “Wal-Mart’s public-relations department wants you to believe the company is aggressively fighting global warming, but at the end of the day their project fails to meet even the minimum standards required by California law.”

The Center for Biological Diversity does not provide details on its site on how the project fails to meet standards.
