WASHINGTON - The Obama administration is set to announce that it will require new rules to cut emissions from airplanes, expanding a quest to tackle climate change that has included a string of significant regulations on cars, trucks and power plants.

The Environmental Protection Agency is expected to report as early as Friday its conclusion that greenhouse gas emissions from airplanes endanger human health because they significantly contribute to global warming, although people familiar with the agency's plans said the announcement could slip into next week.
