This is the best summary I could come up with:

Flights with a rail alternative that takes less than two and a half hours will no longer be allowed, “except in cases of connection with hub airports that link with international routes”.

It comes after the French government officially banned domestic flights for journeys that can be made in less than two and a half hours by train in May 2023.

The text agreed by the two political parties - PSOE and Sumar - also seeks to analyse the potential impact of restricting private jet use and a European Union directive on taxing energy products, including kerosene which is used as an aviation fuel.

The coalition of environmental groups said that 11 air routes could be replaced by train journeys under four hours, slashing Spain’s CO2 emissions by nearly 10 per cent.

PP member Guillermo Mariscal explained that he believes the initiative is “ineffective” because it would only result in a 0.06 per cent reduction in emissions according to data from the College of Aircraft Engineers (COIAE).

Last year COIAE shared a statement expressing its disagreement with a plan to cut flights of under three hours, claiming it would have almost zero impact on carbon emissions.
