Distributional fairness of personal carbon trading
通过芬兰拉赫蒂市居民调查，发现多数人认为人均等额分配的碳交易方案在收入再分配上是公平的，但农村家庭和有孩家庭的不成比例负担被认为不公平，政治倾向和气候责任观是主要预测因素。
Distributional fairness concerns are key barriers to the implementation of climate policies. Emission rights allocation is the decisive distributional feature of personal carbon trading (PCT) that is intended to incentivise individuals' low-carbon choices. The aim of the current study was to identify the predictors of the perceived distributional fairness of PCT. The perceived fairness of expected income redistribution through a PCT scheme in mobility was studied by a survey conducted among citizens of a medium-sized North European city, Lahti, Finland (n = 358). The progressive distributional effects of PCT with equal-per-capita allocation were perceived as fair by the majority, while the consequent burdens on rural households and families with children were strongly perceived as unfair. Political orientation and views on climate responsibility were the main fairness predictors for redistribution through PCT. The results imply that an allocation that acknowledges vulnerable groups with higher mobility needs would be considered fairer than an equal-per-capita allocation. An allocation that is sensitive to context-specific distributional fairness concerns appears to be a crucial feature of PCT for public acceptability.
