Abstract
Air travel contributes a substantial share of global greenhouse gas emissions and is projected to rise. To reduce emissions, airlines and policymakers must understand consumer preferences and willingness to pay (WTP) for reductions. Several studies have been conducted for this purpose, with considerable variation in reported WTP values. This paper undertakes a meta-analysis and qualitative review to better understand the key factors influencing WTP drawn from 31 primary studies. A major finding is that WTP could be more than double for a credible offsetting scheme compared to one lacking credibility. Additionally, framing the offset as “per flight” rather than “per tonne CO2” increases WTP, while there appears to be no differential impact of a voluntary versus mandatory schemes. As expected, WTP increases in income, education, and pro-environmental attitudes. The results yield important insights for the design of effective carbon offsetting schemes, thereby enhancing sustainability of aviation.
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.
