The shipping sector’s carbon footprint
Just came across this interesting blog on the shipping sector's emissions. I think this highlights the pressure that is building up at the moment.
"One of the bits of data posted on the site is a graph comparing the CO2 emissions from moving a ton of cargo 1 kilometre with the emissions that would result from moving it instead by rail, road or air. For shipping, the figure is 12.97 grammes of CO2 – as opposed to 17 grammes for rail, 50 for road and 552 for air. Presumably, the shipping companies involved think this constitutes a good argument in shipping’s favour. But in fact, the surprise is that shipping’s emissions are so high relative to the other three transport modes, rather than so low.
It’s no great shock to see aviation emissions outstripping shipping’s by such a big margin – but remember that air freight is used for much smaller volumes and weights of cargo, usually of highly perishable goods. The fact that shipping emissions are all of two thirds of those of rail, though – and well over a fifth of those of heavy goods vehicles on the road – is really surprising." in full
