Correcting Consumer Misperceptions about CO2 Emissions
研究发现消费者对碳排放存在严重误解且愿意减排，但纠正这些误解并未改变实际消费行为，质疑了信息提供作为气候政策工具的有效性。
Policy makers frequently champion information provision about carbon impact on the premise that consumers are willing to mitigate their emissions but are poorly informed about how to do so. We empirically test this argument and reject it. We collect an extensive new dataset and find both large misperceptions of the carbon impact of different consumption behaviors and clear preferences for mitigation. Yet, in two separate experiments, we show that correcting beliefs has no effect on consumption in large representative samples. Our null results are well-powered and informative, as we target information for maximal impact. These results call into question the potential of correcting carbon footprint misperceptions as a tool to fight climate change.
