The Fukushima Daiichi accident released huge amounts of radioactive material over a wide area. We can appreciate the geographical extent of radioactive contamination from the information published online by the Japanese government. Historically, this is an unprecedented situation, which allows "natural experimentation" to estimate the causal effects of radioactive contamination on our society. This study focused on property value losses caused by the accident and analyzed changes in land appraisals around the Fukushima Daiichi plant from July 2010 to July 2011 within the framework of hedonic approach. Thus, we estimated the short‐run impact of the contamination or the change in marginal value of proximity to the plant. The results suggest that the appraisals significantly and monotonically depreciated with increasing contamination levels. However, there was no evidence to suggest changes in the marginal value of proximity to the plant. A comparison between the appraisals and transaction prices indicates that this result could be interpreted as an underestimate of actual property value losses.

From the perspective of risk, nuclear‐power‐related facilities (NPRFs) are often regarded as locally undesirable land use. However, construction of NPRFs contributes to social infrastructural improvement and job creation in the host communities. This raises a question: How large are these positive and negative effects? To approach this question from an economic viewpoint, we estimated the hedonic land price function for the Mutsu‐Ogawara region of Japan from 1976 to 2004 and analyzed year‐by‐year fluctuations in land prices around the NPRFs located there. Land prices increased gradually in the neighborhood of the nuclear fuel cycle facilities (NFCFs) in Rokkasho Village, except for some falling (i) from 1982 to 1983 (the first official announcement of the project of construction came in 1983), (ii) from 1987 to 1988 (in 1988, the construction began and opposition movements against the project reached their peak), and (iii) from 1998 to 1999 (the pilot carry‐in of spent fuels into the reprocessing plant began in 1998). Land prices around the Higashidori Nuclear Power Plant decreased during the period 1981–1982, when the Tohoku Electric Power Corp. and Tokyo Electric Power Corp. announced their joint construction plan. On the other hand, we obtained some results, even though not significant, indicating that land prices around Ohminato and Sekinehama harbors changed with the arrival and departure of the nuclear ship Mutsu, which suffered a radiation leak in 1974.

Climate change mitigation strategies offer significant societal co-benefits such as improvement in public health, air quality, local economy, and even safety. By considering these co-benefits during the transportation planning process, local governments would be able to link their local appreciate mitigation actions into the Sustainable Development Goals (SDGs), where diverse objectives should be achieved simultaneously. This study first clarifies the co-benefits approach to climate change mitigation in the transport system, by introducing an integrated multiple-impact framework known as A-S-I (Avoid-Shift-Improve) to evaluate the co-benefits. Thereafter, it applies the quantitative modeling approach to assess public health and environmental co-benefits of the implementation of the Tehran Transportation Master Plan, "the TTMP" in the city of Tehran, Iran, which includes targeted interventions such as shifting from private vehicles to the urban transport system, improving vehicle technologies and introducing alternative fuels. The results from the application of "the TTMP" reveal a significant reduction of CO2 and other local air pollutant emissions by 12.9 and 1.4 million tons, respectively, prevention of about 10, 000 mortality cases, and more than USD 35 million savings by 2030.
