摘要:Food and the environment are at the heart of sustainable development. However, the results of experimental work carried out by researchers from the INRA-SAE2 Department on consumer perceptions and willingness-to-pay for products respecting some of the criteria of sustainable development, show that information transmission to consumers via labels is imperfect. In order to promote sustainable development practices, we show that use of other tools, such as taxes and quality standards, could be conceivable.
