Individual voluntary climate action could contribute to closing the gap between global emission targets and the instruments in place. However, complex regulatory frameworks make it difficult for individuals to understand which actions align with their goals. Expert advice might provide guidance, but it is not trivial how detailed the advice should be. In a large consequential choice experiment with five informational load conditions, this paper uses the voluntary cancellation of European Union Allowances as an application to narrow down a minimum amount of information required to induce effective actions. We find a clear pattern of advice being processed and followed, even if it includes a demanding level of detail and counters prior convictions. Moreover, a mere assertion is highly effective already. These results are good news for efforts to increase the effectiveness of voluntary climate action.
个人自愿的气候行动有助于缩小全球排放目标与现有手段之间的差距。然而，复杂的监管框架使个人难以理解哪些行动符合他们的目标。专家建议或许能提供指导，但建议应详细到何种程度并非易事。在一项具有五种信息负荷条件的大型结果性选择实验中，本文将欧盟排放配额的自愿注销作为一个应用案例，以确定促使有效行动所需的最少信息量。我们发现，即使建议包含要求较高的详细程度且与先前信念相悖，也存在被处理和遵循的明确模式。此外，仅仅一个断言就已经非常有效。这些结果对于提高自愿气候行动有效性的努力而言是个好消息。
