CP has developed the first environmental simulator for the transport sector in Portugal which lets you see your energy efficiency and helps you change your habits to become more environmentally responsible.
Use the simulator and you will see that on average a car (at the legal speed limit) emits 38.47 kg of carbon dioxide per passenger on a journey between Lisboa Oriente station and Oporto Campanhã station. A CP Alfa Pendular train carrying 301 passengers emits just 7.05 kg per passenger.
The difference is even greater if we compare aircraft emissions. An aeroplane on the same route would emit 4 times more carbon dioxide.
