Vehicle sharing is one of a number of green transport initiatives the DCA promotes, often within a site specific travel plan. The DCA researches and disseminates publications to its staff such as "Making car sharing and car clubs work" and "Making Smarter Choices Work" and encourages the promotion of travel planning and inclusion of car sharing and car club schemes. Other measures supporting sustainable travel include secure cycle parking and showers and events to promote walking and cycling etc. Interest free loans for bicycles are also available to staff to encourage more sustainable travel.
DCA is also a member of a Civil Service Travel Group, which comprises all major Government Departments. Its key aim is to improve travel sustainability across the entire civil service by developing and delivering on action plans for each Department.
