“…It also found that household income, whether they were spending money on treating respiratory diseases, whether they are aware of the connection between air pollution and health, and the level of education are factors that affect respondents' payment decisions. Lee et al [26] used a Health Risk Assessment and CV to estimate the PM 2.5 damage cost and the WTP for reducing premature deaths from the PM 2.5 in Seoul, South Korea, respectively. Employing the death rate from the PM and GNP per capita, EI-Fadel and Massoud [27] assessed the economic benefit from the reduction of fine dust in urban areas.…”

“…First, of the studies that measured people's WTP for reducing the PM 2.5 concentration remain scarce, more tackled particulate matter and air quality (e.g., [25][26][27][28][29][30]). In this regard, this study can contribute to the literature on the economic valuation of the public value of reducing the PM 2.5 concentration.…”

Public Value of Enforcing the PM2.5 Concentration Reduction Policy in South Korean Urban Areas

As the number of cars and the electricity produced from coal-fired generation has been increasing, PM 2.5 , particles smaller than 2.5 µm in diameter, has become a serious problem in South Korean urban areas. This is especially notable, given that the PM 2.5 warning was issued 89 times during 2016. Because of this, the South Korean government is seeking to enforce a policy of reducing the number of PM 2.5 warnings by half using various policy instruments from now until 2022. This article tries to obtain information about the public value of the enforcement. For this purpose, household willingness to pay (WTP) for the enforcement is investigated, applying the contingent valuation (CV) approach. A survey of 1000 households was carried out in South Korean urban areas. The data on the WTP were gathered using a dichotomous choice question and analyzed employing the spike model. The mean WTP estimate is obtained as KRW 5591 (USD 4.97) per household per year, which is statistically significant. The total public value expanded to the population amounts to KRW 98.9 billion (USD 87.8 million) per year. The information can be utilized in policy-making and decision-making about the reduction of the PM 2.5 concentration.

“…First, studies that investigate the role of NG to abate PM emissions compared with that of coal, remain scarce as most of the related studies have tackled PM itself [24][25][26][27][28][29]. Considering this, the present study can contribute to the literature on the additional WTP for electricity from NG-fired generation over coal-fired generation in view of PM emissions abatement.…”

Do People Place More Value on Natural Gas Than Coal for Power Generation to Abate Particulate Matter Emissions? Evidence from South Korea

Abstract:As of 2017, coal is responsible for about half of all power generation in South Korea, while natural gas (NG) is responsible for about 20%. This increases particulate matter (PM) emissions, as coal emits 6 to 55 times more PM than NG in the course of power generation. Increased PM concentration causes visibility impairment and acute respiratory diseases. Thus, the South Korean government is seeking to shift from coal to NG power generation for the purpose of abating PM emissions. The government also considers NG as a bridge energy to facilitate the transition from fossil fuels to renewable energy. This article attempts to answer the question, "Do people place significant value on shifting from coal to NG power generation in order to abate PM?" To this end, additional willingness to pay (WTP) for NG over coal for electricity for the purpose of PM emissions abatement was assessed from 1000 South Koreans' contingent valuations (CV). More specifically, each of these randomly chosen interviewees was asked about her/his WTP for the switch from coal to NG for 1 kWh of electricity use. The average additional WTP estimate was KRW 31.27 (USD 0.028) per kWh, which is equivalent to 28.8% of the average price of electricity in 2017. Moreover, this estimate is statistically significant. The generation cost of NG is about KRW 100.13 per kWh, which is higher than that of coal (KRW 78.5 per kWh). The gap is KRW 22.08 per kWh, which is less than the additional WTP. Thus, it is obvious that the governmental policy of shifting from coal to NG for power generation in order to abate PM emissions is supported by the public and, hence, the shift should be made gradually.

“…In recent years many studies in the field have been conducted in developing Asian countries. Lee et al (2011) estimated a WTP amount for reducing the mortality rate in order to evaluate a statistical life value in Seoul, Korea. The monthly average WTP for 5/1,000 mortality reduction over 10 years is $20.20 US, and the implied value of statistical life (VSL) is $485,000.…”

“…The monthly average WTP for 5/1,000 mortality reduction over 10 years is $20.20 US, and the implied value of statistical life (VSL) is $485,000. The damage cost estimate due to risk from PM2.5 inhalation in Seoul is about $1,057 million per year for acute exposure, and $8,972 million per year for chronic exposure [42]. Huang et al (2012) estimated the adverse health effects of particulate matter pollution in the Pearl River Delta in southern China.…”
