This book examines ways to ensure that the rights, interests and concerns of young people are properly represented in Western democracies. It explores key questions regarding the implementation of youth quotas from different perspectives (including philosophy, political science, sociology and demography) and examines whether youth quotas and other measures that give the young more voice and influence in political institutions are a good means for promoting the cause of intergenerational justice. In particular, it investigates how and if youth quotas can be used to ensure that the environmental interests of young and future generations are being taken into account.
