Greenpeace volunteers shut down the assembly line making gas-guzzling Range Rovers by using safety shut-down buttons to cut off power and then handcuffing and chaining themselves to unfinished vehicles along the 150m long assembly line and branding it a climate crime scene. The Range Rover is the UK's least fuel-efficient 4x4 doing a criminal 12 miles to the gallon in urban areas. In the UK, road transport accounts for about a quarter of the emissions that cause climate change, which makes it the second biggest source of greenhouse gases. The trend of 4x4 vehicles as urban run-arounds is increasing the amount of emissions going into the atmosphere.
