Background: Over the last decade, medical student residency applicants have shown a substantial increase in the number of interviews attended, which is associated with a significant increase in travel. The carbon footprint associated with residency interviews has not been well documented prior to this investigation, and is a critical issue related to climate health.
Objective: The purpose of this study is to document the carbon footprint associated with travel to residency interviews of the applicants from a single institution.
Methods: Graduating medical students from the University of Michigan Medical School were surveyed in 2020 to gather information regarding travel related to residency interviews. A validated carbon emissions calculator was used to determine the associated carbon footprint.
Results: Response rate was 103 of 174 (59%). Average interviews per student across all specialties was 14.39 interviews per student. The overall class average for total carbon footprint per student was calculated as 3.07 metric tons CO, making the class average carbon footprint per interview 0.21 metric tons CO. If we extrapolate the results of our study to all residents, the resulting CO emissions approach 51 665 metric tons CO per year, which is equivalent to the amount of CO produced by 11 162 passenger cars in 1 year.
Conclusions: Medical education leaders could help reduce the carbon footprint by encouraging a reduction in number of in-person interviews attended by applicants.

Department of Civil Engineering, Faculty of Engineering, King Mongkut's University of Technology Thonburi, Bangkok, 10140, Thailand.
This study introduces an innovative approach to enhancing recycled aggregate concrete (RAC) by incorporating nanosilica (NS) and natural fibers (NF), specifically sisal fiber (SF) and palm fiber (PF). This novel combination aims to overcome the inherent limitations of RAC, such as reduced strength and durability, while promoting sustainability in construction. The research focuses on evaluating the mechanical properties of RAC, including compressive and flexural strengths, through the integration of NS and NF.

Background/aims: Although gastrointestinal endoscopy (GIE) is a major contributor to the carbon footprint of national healthcare, the amount of medical waste generated by GIE procedures is not reported in South Korea. This study aimed to measure the amount of medical waste generated from GIE procedures in South Korea.
Methods: We conducted a 5-day audit of medical waste generated during GIEs at seven hospitals.

Evaluating and predicting how carbon storage (CS) is impacted by land use change can enable optimizing of future spatial layouts and coordinate land use and ecosystem services. This paper explores the changes in and driving factors of Zunyi CS from 2000 to 2020, predicts the changes in CS under different development scenarios, and determines the optimal development scenario. Woodland and farmland are the main land use types in Zunyi.
