Shipping our heavy goods around the world is a huge carbon emitter. In the UK, we transport a vast amount via roads which has the same carbon footprint as air travel, buses and domestic shipping combined. So could we be shipping in a more environmentally friendly way? On this week’s ClimateCast, Tom Heap boards a freight train to find out how rail freight fits into our net-zero future.He finds out why the cost of electricity means freight operators are running more diesel than electric and what changes are needed to the UK’s infrastructure to slash shipping emissions.Plus, our climate reporter Victoria Seabrook joins Tom to talk about what’s been happening at COP28 in Dubai this week.Producers: Emma Rae Woodhouse and Luke DenneEditor: Philly Beaumont
