As a specific example, but only one of very many similar broad definitions of Rebound, the Finnish Society for Further Studies and the Finnish Association for the Club of Rome, in their publication ‘On the Way to Sustainable Development’ (1997) put it thus: ‘Even if resource productivity were to advance by dematerialisation, the exploitation of natural resources and space will increase as a consequence of increasing consumption and population. There is, as yet, no solution to this rebound effect.’ Whilst the sentiment is undoubtedly correct, the definition of rebound implied by the treatment is very wide indeed, and is pessimistic to the point of despair.
