Scientists fly to test gases
Scientists are to take to the skies in a bid to measure the amount of greenhouse gas emitted in the UK.
A team led by the University of Edinburgh will man a research aircraft equipped with sensors to measure carbon dioxide, methane and nitrous oxide levels in the atmosphere.
Samples will also come from sensors on a North Sea ferry and several high points, including the BT Tower in London.
The four-year project will track the progress made on the target to cut pollution by 80 per cent by 2050.
