Greenpeace has confirmed it will take legal action against the UK Government over claims it failed to check the environmental impact of burning gas from the Jackdaw gas field off the coast of Aberdeen.
The government gave its approval for Shell to develop the field for gas extraction on 2 June.
It comes as the UK has faced a summer of unprecedented heat, say campaigners, and Greenpeace warns if gas from Jackdaw is burnt, it could produce CO2 emissions equivalent to more than that of Ghana.
