Using a global dataset of almost 86,000 syndicated bank loans, we find that a higher climate vulnerability of a firm’s host country leads to higher costs of borrowing. The effects of physical climate risk on loan pricing are particularly large if loans have long maturities and if borrowing firms are in financial distress. In addition to loan pricing, banks also adjust other loan terms, such as loan size, collateral requirements, or fees, to manage their exposure to their borrowers’ physical climate risk. As climate risk may also directly affect loan pricing, e.g., via general updates of credit risk models due to observed changes in climate risk, we extend the analysis to firm-level credit risk ratings. The results show that physical climate risk negatively affects long-term credit risk ratings, while it does not play a role in short-term credit risk, and hence support the proposed channel that physical climate risk affects loan pricing via its effect on firms’ default probabilities.</div></div>","PeriodicalId":15763,"journal":{"name":"Journal of Environmental Economics and Management","volume":"137 ","pages":"Article 103280"},"PeriodicalIF":5.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145940301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, groundwater extraction could still be considered to be ‘weakly sustainable’ if it generates investments in man-made capital that offset the loss of natural ‘groundwater capital’ and enable income to be sustained even as the resource is depleted. In this paper, we examine whether the withdrawals of groundwater for irrigation in India have resulted in household-level investments in physical and human capital. Our empirical strategy compares villages in the same administrative units that overlie aquifers with different water storage capacities and, therefore, endowed with different levels of access to the resource. We find that greater access to the resource results in more irrigation, as expected, as well as higher asset wealth and educational attainment. The results suggest that deeming India’s irrigation-based rural development as unsustainable purely because of the decline in water tables may require reconsideration, provided that human capital is used to productively shift income from farm to off-farm sources.</div></div>","PeriodicalId":15763,"journal":{"name":"Journal of Environmental Economics and Management","volume":"137 ","pages":"Article 103274"},"PeriodicalIF":5.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145940303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The survey elicits respondents' willingness to pay (WTP) for achieving global net zero by 2050 and uses a split sample design to test whether WTP is affected by the distribution of decarbonization costs across households.

Although scientists agree that nitrogen compounds from human activity, notably agriculture, enter groundwater systems, empirical estimates of the impacts of land use on nitrate concentrations in well water are still lacking. We provide evidence on such impacts by combining nitrate measurements from 6016 groundwater wells with remotely sensed California land use data from 2007–2023. We categorize agricultural land uses according to crops’ propensities to leach nitrogen and further consider urban development, in addition to undeveloped land—the default land use. Results show that a 10 percentage point increase in the share of land used to grow high-nitrogen crops within 500 m of a well is associated with an 11.6% increase in nitrate concentrations a decade later, while the same increase in urban developments contributes about a 10% increase. When conditioning on initial nitrate measurements, the impact of nearby land use attenuates while initial concentrations explain a large share of future variation in concentrations, demonstrating the persistent nature of nitrates in groundwater. A calculation based on our regression estimates implies that replacing high-nitrogen with low-nitrogen crops around sample wells would achieve a 4.6% reduction in nitrate concentrations, saving municipal water systems $25 million annually. We evaluate the opportunity cost of such crop substitution to be large; however, targeting only the crops with the highest propensity to leach nitrates easily passes a cost-benefit test.</div></div>","PeriodicalId":15763,"journal":{"name":"Journal of Environmental Economics and Management","volume":"137 ","pages":"Article 103284"},"PeriodicalIF":5.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146034871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
