    Consumers’ knowledge about climate change
    (Springer, 11.01.2012) Tobler, Christina; Visschers, Vivianne; Siegrist, Michael
    Several studies have unveiled various misconceptions about climate change that the public holds, for instance, confusion about climate change and ozone depletion. However, so far, there has been no uniform and standardized way to measure climate-related knowledge, which complicates comparisons between different countries or samples. To develop an extensive knowledge scale, we therefore examined the Swiss public’s understanding of climate change in a mail survey and related this scale to attitudes toward climate change. We thereby aimed to consider a broad range of climate-related knowledge, namely physical knowledge about CO2 and the greenhouse effect, knowledge about climate change and its causes, knowledge about the expected consequences of climate change, and action-related knowledge. The questionnaire included items of different degrees of difficulty, ranging from knowledge that is covered by newspapers to experts’ knowledge. Our findings indicate that people still hold several misconceptions, although people’s knowledge related to CO2 seems to have increased compared to previous studies. Of all knowledge subscales, knowledge about climate change and causes was most strongly related to attitudes toward climate change.

    Organic tomatoes versus canned beans: How do consumers assess the Environmental Friendliness of Vegetables?
    (SAGE, 09.01.2011) Tobler, Christina; Visschers, Vivianne; Siegrist, Michael
    The assessment of a food product’s environmental friendliness is highly challenging for consumers because such an assessment requires the consideration of various product characteristics. Furthermore, products often show conflicting features. This study uses a choice task and a questionnaire to examine how consumers judge the environmental friendliness of several vegetables. The consumers’ assessment is compared with life cycle assessment (LCA) results, which represent the overall environmental impact of a product throughout its lifespan. In contrast to the LCA, consumers consider transportation distance rather than transportation mode and perceive organic production as very relevant for the environmental friendliness. Furthermore, consumers assess the environmental impact of packaging and conservation as more important than the LCA results show. Findings also suggest the current product information for vegetables is insufficient for judging their environmental friendliness. Implications for information campaigns and ecological food labeling are discussed.
