Plans to redevelop Carlisle Airport have sparked protests from climate change protesters. Stobart Air Limited wants to invest £25 million in a rebranded Carlisle Lake District Airport that will increase freight and passenger flights. The plans include the construction of a new runway, passenger terminal, air traffic control centre, hangars, office building, warehouses and car parking facilities. The current runway was built in the 1940s and can only handle a limited amount of traffic. Campaigners are unhappy about the plans attracting large passenger aircraft which they say would pose a threat to the environment.
