The Tax Payers Alliance, using Freedom of Information requests, have discovered the Department of Energy and Climate Change spent £1.5million on flights in the last two years. 
The most expensive flight in the two years was a trip from Cancun to London following an international climate change conference.
Climate change ministers and officials spent £1.5 million on flights in two years with £250,000 of the bill racked up on domestic journeys, research has found.
As well as tickets to far flung locations, the Department of Energy and Climate Change (Decc) team regularly booked seats between London and Aberdeen, where its North Sea oil and gas inspectors work. Flights from London to Manchester and Glasgow and between Aberdeen and Norwich, Southampton and Humberside were also recorded.
