A new study calculates the environmental effects of passenger trips of typical distances for business or holiday trips using different modes of transport. The report, published in the journal Environmental Science and Technology, is by researchers at Austria's International Institute for Applied Systems Analysis (IIASA) and the Norwegian Centre for International Climate and Environmental Research (CICERO).
“Travelling alone in a large car can be as bad for the climate as flying, but driving with three in a small car could have an equally low impact as a train ride,” said IIASA’s Jens Borken-Kleefeld. A 1000 km trip alone in a big car could emit as much as 250 kg of carbon dioxide (CO2), the researchers calculated, while a train trip or carpooling in a small car could emit as little as 50 kg of CO2 for each traveller.
