A lawsuit against United States Environment Agency later revealed that the court ruling was lagging ‘existing technology by more than 10 years’.
For the record commercial are singled among the largest source of transportation greenhouse gas emissions hence have not been subjected to litigation.
In a latest move the US based plane maker Boeing Company has backed fuel efficiency standards for new aircraft – the first of their kind – finalised by the Trump administration in its waning days that a dozen states have challenged as too lenient, and that President Joe Biden’s administration is reviewing.
The move follows an appeal by the company this week in Washington, DC where it sought an approval to intervene on behalf of the Environmental Protection Agency (EPA).
Currently the EPA is being sued over its earlier decision to finalise the first-ever standards regulating greenhouse gas emissions from aeroplanes. The plaintiffs, 12 states, the District of Columbia and three environmental groups, want tougher emissions rules.
The states said late last year that the EPA rule lags “existing technology by more than 10 years and would result in no [greenhouse gas] reductions at all compared to business-as-usual”.
Commercial planes have been the largest source of transportation greenhouse gas emissions not subject to rules.
In 2016, the United Nations’s International Civil Aviation Organization (ICAO) agreed on global aircraft emissions standards aimed at makers of small and large planes, including Airbus SE and Boeing Co, which both endorsed the rules.
Boeing noted the ICAO emissions standards effort began under former President Barack Obama’s administration, in which Biden was vice president.
The planemaker argued that it is “essential” that rules “be reasonably achievable, given the billions of dollars it costs to design, build, and certify new airplanes”.
“Attempts to overturn regulation directly aligned with successful cooperative international efforts to combat climate change, supported by more than 190 countries, will only discourage future international agreements,” Boeing said in a statement.
