Abstract

The government plans to increase the number of hydrogen fuel cell heavy-duty trucks (HTs) to 30,000 by 2040 reducing the number of internal combustion engine HTs in South Korea. The plan will abate CO₂ emissions in the mobility sector by 8.74 million tons. This study seeks to assess public acceptance of the plan by applying contingent valuation (CV) and collecting data on household willingness to pay (WTP). To this end, a sample of 1000 households was surveyed through one-on-one interviews by trained interviewers in 2024. A yearly household income tax was used as the payment vehicle. A spike model to reflect a WTP of 0 was applied to the data. The average annual WTP per household was obtained as KRW 3121 (USD 2.28) from 2024 to 2033, securing statistical significance. The national present value of it was worth KRW 572.4 billion (USD 418.4 million) when applying a social discount of 4.5 %. As of 2024, the present value of the national WTP and the carbon credit price were found to be KRW 65,465 (USD 47.85) and KRW 9245 (USD 6.76) per ton of CO₂, respectively. The former is much greater than the latter. Thus, the execution of the plan is socially profitable.

韩国公众对扩大氢燃料电池重型卡车的接受程度：基于支付意愿的货币评估

政府计划到2040年将氢燃料电池重型卡车（HTs）的数量增加到3万辆，从而减少国内内燃机重型卡车的数量。该计划将使交通行业的二氧化碳排放量减少874万吨。本研究旨在通过条件评估（CV）和收集家庭支付意愿（WTP）数据来评估公众对该计划的接受程度。为此，在2024年，通过训练有素的采访者对1000户家庭进行了一对一访谈。每年的家庭所得税被用作支付工具。对数据应用了反映WTP为0的峰值模型。从2024年到2033年，每户的年平均WTP为3121韩元（2.28美元），具有统计学意义。如果加上4.5%的社会折扣率，其国民现值为5724亿韩元（约4.184亿美元）。以2024年为基准，国家WTP的现值为每吨二氧化碳6.5465万韩元（47.85美元），碳信用价格为9245韩元（6.76美元）。前者比后者大得多。因此，该计划的执行具有社会效益。

期刊介绍： Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
