An anonymous reader quotes a report from ABC News: New York, California and nine other states sued the Trump administration Tuesday over its failure to finalize energy-use limits for portable air conditioners and other products. The new standards would reduce greenhouse gas emissions, save businesses and consumers billions of dollars, and conserve enough energy to power more than 19 million households for a year, but the U.S. Department of Energy has not met a requirement to publish them by now, according to attorneys general who filed the lawsuit (PDF) against the DOE in federal court in San Francisco. That means the standards are not legally enforceable. The other states in the lawsuit are: Connecticut, Illinois, Maine, Vermont, Washington, Massachusetts, Pennsylvania, Oregon and Maryland. The City of New York is also a plaintiff. The energy efficiency standards at issue in the lawsuit also cover walk-in coolers and freezers, air compressors, commercial packaged boilers and uninterruptible power supplies. There is currently no federal energy standard for air compressors, uninterruptible power supplies or portable air conditioners, according to the lawsuit. The lawsuit seeks a court order requiring the DOE to publish the new standards as final rules.
