Working Hours and Sustainable Development

<title>Abstract</title> Many works on sustainable development stress the part played by reduced working hours in the promotion of a model for alternative development. The direct link between working hours and the environment, however, still deserves to be supported. This is the issue we would like to discuss through an analysis of the relationships between consumption and working hours. We use surveys on French household expenses to highlight the environmental consequences of long hours: they encourage goods and energy-intensive consumptions and favour conspicuous expenditure and non-sustainable lifestyles.
