Assessing sustainability:: An assessment framework to evaluate Agenda 21 actions at the local level

In Switzerland, communities are encouraged to define and to report on local Agenda 21. This paper presents an analysis framework to help local communities set sustainable development priorities and to follow through with appropriate actions. Four Swiss communities, from the French-speaking part of Switzerland, actively follow the project: Lausanne (114 304 citizens),Vevey (15 364 citizens), Mannens-Grandsivaz (505 citizens) and Essertines/Yverdon (666 citizens). The analysis framework developed is constituted of four interdependent fields: the societal characteristics, the individual or collective behaviours, the end objectives or sustainability impacts and the inhabitant's perception of these three fields. The link between society and behaviour can be studied through sociological analyses. The link between behaviour and environmental impact can be established thanks to Life Cycle analysis and Input/Output analyses. At each level, sustainable development indicators can be defined. As an application of the framework, the citizen energy consumption has been studied and expressed in energy slaves (= 3150 MJ/Year). A Swiss citizen needs altogether 69 slaves, 20 for his private consumption of goods and services, 19 for housing, 11 for transport, 11 for food and 8 for his consumption of public goods. If one fifth of the inhabitants of Lausanne, wanting to live closer to nature, actually moved out of town, the region would need 10 436 more slaves for 3500 persons happily living in the countryside.
