The majority of the savings came from a 12 per cent reduction in greenhouse emissions (saving £40m), with the remainder coming from a five per cent reduction in waste (saving £4.7m), and a three per cent fall in water consumption (saving £4.2m).
The civil service also achieved a 35 per cent reduction in domestic flights, and a 24 per cent reduction in paper use.
Some of the measures implemented to achieve these savings include restrictions on staff travel, greater teleconferencing, and installing recycling systems.
