Curtailment behaviour pertains to using less and limiting our resource use. It is related to behaviour choice. This includes reducing energy use, water, waste, material purchases, children etc. Since these behaviours usually involve people’s unconscious habits and routines, they are difficult to change as the behaviour needs to be done repeatedly for it to have a positive meaningful on the environment. This means new habits and routines need to be created. For example, one way to get people to reduce energy use is to use candles instead of lights. However, people are used to using flicking on the light switch each time they come into a room and it is difficult for them to change this habit to lighting candles.
