The market for voluntary carbon offsets is growing globally. Voluntary carbon offsets are however also controversial – particularly for environmentalists and within environmental associations. In fact, the discourse on voluntary carbon offsets indeed often refers to terms such as "sale of indulgences" or "greenwashing". In order to discuss this controversial topic, the German Federal Environmental Agency organised the conference "Voluntary carbon offsets and sustainable lifestyles: A good match?" on 10 November 2014 in Berlin. This conference documentation summarizes the presentations, thesis papers and results of the conference discussions.
