Abstract

Urban transport is a major driver of global CO₂ emissions which many economists call for to be mitigated through carbon pricing. However, carbon pricing policies are frequently criticized and resisted for having adverse distributional impacts, often despite a lack of quantified evidence. We examine the impact of a fuel levy on access to employment opportunities via transit in Kinshasa and Rio de Janeiro based on travel time and budget. The results indicate that fuel price increases reduce accessibility with clear socio-spatial heterogeneity. Mid- to high- income households are the most affected in terms of accessibility losses. But even small absolute losses can exclude the poorest from accessing a “reasonable” pool of jobs. The results also show that impacts vary more within income groups than across: locational decisions are key determinants of the outcome alongside income. Transit decarbonization and land use policies can help mitigate the negative impacts of carbon pricing.

碳定价和交通运输可达性

城市交通是全球二氧化碳排放的主要驱动因素，许多经济学家呼吁通过碳定价来缓解二氧化碳排放。然而，碳定价政策经常受到批评和抵制，因为它会产生不利的分配影响，尽管往往缺乏量化的证据。我们根据旅行时间和预算，研究了燃料税对金沙萨和里约热内卢过境就业机会的影响。结果表明，燃料价格上涨降低了可达性，且具有明显的社会空间异质性。在可达性损失方面，中高收入家庭受影响最大。但即使是很小的绝对损失，也会使最贫穷的人无法获得“合理的”就业机会。研究结果还表明，不同收入群体之间的影响差异更大：区位决策与收入一样，是决定结果的关键因素。过境脱碳和土地利用政策可以帮助减轻碳定价的负面影响。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
