The rise in greenhouse gas emissions from air travel could be reduced by individuals voluntarily abstaining from, or reducing, flights for leisure and recreational purposes. In theory, we might expect that people with pro-environmental value orientations and concerns about the risks of climate change, and those who engage in more pro-environmental household behaviours, would also be more likely to abstain from such voluntary air travel, or at least to fly less far. Analysis of two large datasets from the United Kingdom, weighted to be representative of the whole population, tested these associations. Using zero-inflated Poisson regression models, we found that, after accounting for potential confounders, there was no association between individuals' environmental attitudes, concern over climate change, or their routine pro-environmental household behaviours, and either their propensity to take non-work related flights, or the distances flown by those who do so. These findings contrasted with those for pro-environmental household behaviours, where associations with environmental attitudes and concern were observed. Our results offer little encouragement for policies aiming to reduce discretionary air travel through pro-environmental advocacy, or through 'spill-over' from interventions to improve environmental impacts of household routines.

“绿色”在地面上，但不在空中：亲环境态度与家庭行为有关，但与随意的空中旅行无关。

出于自愿目的，出于休闲和娱乐目的而放弃或减少航班的人，可以减少航空旅行带来的温室气体排放量的增加。从理论上讲，我们可能希望那些具有亲环境价值取向并关注气候变化风险的人，以及那些从事更多亲环境家庭行为的人，也更有可能放弃这种自愿的航空旅行，或者至少飞不远。对来自英国的两个大型数据集进行了分析，权重代表了整个人口，测试了这些关联。使用零膨胀的Poisson回归模型，我们发现，在考虑了潜在的混杂因素之后，个人的环境态度，对气候变化的关注，或他们日常的环保行为，或者他们从事非工作相关航班的倾向，或从事此类活动的人所乘飞机的距离。这些发现与亲环境家庭行为的发现相反，后者观察到与环境态度和关注有关。我们的结果很少鼓励旨在通过环保倡导或通过干预措施的“溢出”来改善家庭日常活动对环境的影响的旨在减少可自由支配的空中旅行的政策。
