The Environmental Protection Agency (EPA) has established new greenhouse gas (GHG) emission standards for specific types of airplanes and their engines, aligning with international standards set by the International Civil Aviation Organization (ICAO). These standards apply to certain civil jet and larger propeller airplanes, aiming to reduce air pollution and meet the 2016 findings on aircraft emissions. The rule covers new type design airplanes from 2021 and in-production airplanes from 2028, but will not require major changes since most airplanes will already comply with the standards. This action helps U.S. airplane manufacturers remain competitive internationally by ensuring their products meet global emission requirements.

The Environmental Protection Agency (EPA) proposes to approve Idaho's updated regional haze State Implementation Plan (SIP) for the period from 2018 to 2028. Idaho's plan aims to make progress toward improving visibility caused by air pollution in national parks and wilderness areas. The plan includes specific strategies and rules for sources of air pollution, such as factories, to reduce emissions of harmful substances like nitrogen oxides and sulfur dioxide. The EPA found Idaho’s plan to be consistent with federal requirements and intends to incorporate the plan's measures into the state’s legally enforceable air quality rules.
