“…Since the first confirmed case of the coronavirus (COVID-19) was recorded in Wuhan, China in December 2019, the virus has wreaked havoc around the world necessitating drastic and critical responses from the World Health Organization as well as local and national governments around the world to combat the unprecedented global health crisis ( Wang and Su, 2020 ; Nguyen et al, 2021 ). Despite the tremendous progress made in the research and development of new COVID-19 vaccines, the effort to distribute and inoculate the majority of the world population might last well into 2021 and possibly beyond ( Organization, 2019 ; Leet al, 2020 ).…”

Being declared a global emergency, the COVID-19 pandemic has taken many lives, threatened livelihoods and businesses around the world. The energy industry, in particular, has experienced tremendous pressure resulting from the pandemic. In response to such a challenge, the development of sustainable resources and renewable energy infrastructure has demonstrated its potential as a promising and effective strategy. To sufficiently address the effect of COVID-19 on renewable energy development strategies, short-term policy priorities should be identified, while mid-term and long-term action plans should be formulated in achieving the well-defined renewable energy targets and progress towards a more sustainable energy future. In this review, opportunities, challenges, and significant impacts of the COVID-19 pandemic on current and future sustainable energy strategies were analyzed in detail; while drawing from experiences in identifying reasonable behaviors, orientating appropriate actions, and policy implications on the sustainable energy trajectory were also mentioned. Indeed, the question is that whether the COVID-19 pandemic will kill us or provide us with a precious lesson on future sustainable energy development.

“…So far, most of the existing literatures related to the environmental impact of COVID-19 focused on quantifying the concentration change of atmospheric pollutants in the global context ( Bai et al, 2020 ; Deb et al, 2020 ; Le et al, 2020 ; Dang and Trinh, 2021 ; Keola and Hayakawa, 2021 ; Liu et al, 2021c ; Nguyen et al, 2021 ; Smith et al, 2021 ; Venter et al, 2020 ), countries ( Bao and Zhang, 2020 ; Berman and Ebisu, 2020 ; He et al, 2020 ; Petetin et al, 2020 ; Sharma et al, 2020 ; Shi and Brasseur, 2020 ; Wang et al, 2020 ; Isphording and Pestel, 2021 ), regions ( Li et al, 2020 ; Jiang et al, 2021 ; Ma et al, 2021 ; Sulaymon et al, 2021 ; Xian et al, 2021 ), urban ( Adams, 2020 ; Cameletti, 2020 ; Kanniah et al, 2020 ; Kerimray et al, 2020 ; Kumar, 2020 ; Otmani et al, 2020 ; Zangari et al, 2020 ; Zheng et al, 2020 ; Hong et al, 2021 ; Zhao et al, 2021 ), suburban ( Cui et al, 2020 ; Menut et al, 2020 ; Wang et al, 2020 ; Du et al, 2021 ; Hayakawa and Keola, 2021 ; Páez-Osuna et al, 2021 ), and remote areas ( Mandal and Pal, 2020 ). In the transportation sector, many studies concentrated on road traffic ( Ding et al, 2020 ; Dutheil et al, 2020 ; Li et al, 2020 ; Mahato et al, 2020 ; Shehzad et al, 2020 ; Tobías et al, 2020 ; Wang and Su, 2020 ; Xu et al, 2020 ; Chen et al, 2021 ; Hu et al, 2021 ; Rudke et al, 2021 ).…”

This study aims to investigate the coronavirus disease (COVID-19) pandemic effects and associated restrictive rules on ship activities and pollutant emissions (CO 2 , SO X , NO X , PM, CO, CH 4 ) in four major seaports, namely the Ports of Singapore, Long Beach, Los Angeles, and Hamburg. We used 2019 as the baseline year to show the business-as-usual emission and compared with the estimated quantity during the July 2020–July 2021 pandemic period. We also project future ship emissions from August 2021–August 2022 to illustrate two potential port congestion scenarios due to COVID-19. The results show that the ship emissions in all four ports generally increased by an average of 79% because of the prolonged turnaround time in port. Importantly, majority of ship emissions occurred during the extended hoteling time at berth and anchorage areas as longer operational times were needed due to pandemic-related delays, with increases ranging from 27 to 123% in the total emissions across ports. The most affected shipping segments were the container ships and dry bulk carriers which the total emissions of all pollutants increased by an average of 94–142% compared with 2019. Overall, the results of this study provide a comprehensive review of the ship emission outlook amid the pandemic uncertainty.

“…Moreover, the results also showed that cold regions suffered more than warm regions. In a review article, Nguyen et al (2021) discussed how climate change reacts in the presence of COVID-19. Due to the pandemic situation, countries adopted lockdown strategies to save their citizens from the drastic impact of the virus.…”

Neither war nor recession or any kind of prior disaster has been considered a prelude to the looming threat of climate change over the past era as coronavirus (hereafter COVID-19) has in only a few months. Although numerous studies have already been published on this topic, there has not been compelling evidence critically assessing the impact of COVID-19 by and on climate change. The present study fills this gap by taking a more holistic approach to elaborate factors, e.g., natural and anthropogenic factors, ocean submesoscales, radiative forces, and greenhouse gas/CO 2 emissions, that may affect climate change in a more prevalent and pronounced manner. Based on the statistical data collected from the NASA Earth Observatory, the European Space Agency, and the Global Carbon Project, the findings of this study reveal that the climate/environment has improved during COVID-19, including better environmental quality and water quality with low carbon emissions and sound pollution. In the lockdown during the epidemic, the emissions of nitrogen dioxide (NO 2 ) and carbon dioxide (CO 2 ) significantly decreased because of the lower usage of transportation, decreased electricity demand, and halted industrial activities. The policy implications of this study suggested that keeping the climate healthy even in the post-COVID-19 era is a serious concern that needs to be addressed by investing in clean and green projects, ensuring green energy evolution, dealing with a large volume of medical waste, building health-ensuring and livable societies, and halting the funding of pollution. For governmental and regulatory bodies, these factors will provide a strong foundation to build safer, healthier, and environmentally friendly societies for generations to come.
