“…Efforts must be made, and fiscal incentives provided to create comprehensive green recovery plans [51] . For a low-carbon pathway that has the potential to be socially accepted in the aftermath of the pandemic, it is essential to create a smart and safe public transport system [4] , improved opportunities for shared ridership [51] , [52] and an innovative urban infrastructure (e.g., convenient cycling and walking routes, 15-minute cities) [19] . At the same time, socially acceptable travel options that comply with social distancing measures while reducing CO 2 emissions must be scaled up.…”

The coronavirus pandemic has severely affected our daily lives, with direct consequences on passenger transport. This in turn has strongly impacted the energy demand of the transport sector and associated CO 2 emissions. We analyse near real-time passenger mobility and related emission trends in Europe between 21 January and 21 September 2020. We compiled a dataset of country-, sector- and lockdown- specific values, representing daily activity changes in private, public, and active passenger transport. In the aggregate, surface passenger transport emissions fell by 11.2% corresponding to 40.3 MtCO 2 in Europe. This decline was predominantly due to the reduction of private passenger transport in five European countries (France, Germany, Italy, Spain, and the UK). During the first lockdown in April 2020, CO 2 emissions from surface passenger transport declined by 50% in Europe, resulting in a 7.1% reduction in total CO 2 emissions. After April 2020, private passenger travel recovered rapidly, while public passenger flows remained low. Solely prompted by the private sector, a rebound in total emissions and surface passenger transport emissions of 1.5% and 10.7%, respectively, was estimated at the end of the study period. The resulting situation of increased private and decreased public passenger transport is in contradiction to major climate goals, and without reversing these trends, emission reductions, as stated in the European Green Deal are unlikely to be achieved. Our study provides an analysis based on a detailed and timely set of data of surface passenger transport and points to options to grasp the momentum for innovative changes in passenger mobility.

“…In particular, an increasing number of people have begun to pay attention to sustainable development and support policies and regulations related to environmental behavior. However, despite many climate change advocacy activities are conducted, a large number of people are still reluctant to engage in mitigation action (Chen et al, 2020), we must further study how to effectively improve the citizen pro-environmental behavior, including urban ride-sharing (Jin et al, 2020;Zhang et al, 2020), water conservation (Zhuang et al, 2018), public bike-and-ride (Qin et al, 2018), ecotourism (Hwang and Lee, 2018), etc. Existing studies have shown that by publicizing the seriousness of climate change, the public can have a clearer risk perception of climate change and narrow the psychological distance, which helps citizens to make pro-environmental behavior.…”

Global warming and other climate issues seriously threaten global sustainable development. As citizen environmental behavior can have a positive impact on the environment, it is of great theoretical significance and practical reference value to study the impact of psychological distance theory on citizen environmental behavior. This study obtained 2,633 related studies from 1980 to 2020 from the Web of Science as research objects, and used CiteSpace, VOSviewer, Netdraw, and other software programs to perform a bibliometric analysis, which can show the complex relationship implied in the citation, intuitively grasp the development context and hot frontier in this field, and help scholars better study citizen environmental behavior. The results and conclusions are as follows. (1) The related research covered three periods: infancy, growth, and outbreak. (2) Chronologically, the relevant research evolved from building models to analyze the impact of environmental enrichment on human environmental behavior, to studying the motivation behind citizen environmental behavior, and finally to paying attention to sustainable development. (3) A cluster analysis of high-frequency keywords identified three research hotspots: “drivers of psychological distance of environmental change perception on citizen environmental behavior,” “impact of social distance on adolescents’ behavior,” and “construal level theory and citizen green behavior.” Based on these findings, possible future research directions were identified, including changing from a single theory to a combination of multiple theories to comprehensively study citizen environmental protection behavior; analyzing the motivation of citizen environmental behavior and summarizing the general motivation of environmental behavior according to its internal relationship; and determining how to narrow the global psychological distance, strengthen the awareness of the community of human destiny, and explore the establishment of an efficient global climate cooperation mechanism.

“…Using GPS trajectory data, Sui et al (17) showed that the CO, NO x , and HC emissions per passenger per kilometer of taxi trips were approximately 1.45, 1.36, and 1.44 times more than those resulting from ridesourcing trips, respectively. Zhang et al (18) found that ridesharing (the shared rides between drivers and passengers with similar origin-destination pairings, whose driver is also a traveler) could decrease the travel distance by 26.97%. Lokhandwala and Cai (19) concluded that the benefit of ridesharing was significant, with a decreased total travel distance (up to 55%) and reduced carbon emissions (up to 866 metric tons per day) in New York City.…”

The increasing emissions from the transportation sector pose substantial hazards to the environment and human health around the world. With the rapid development of information and communication technologies, ridesplitting, a form of ridesourcing service accessed via smartphone applications, enables passengers with similar origins and destinations to be matched to the same driver and share the ride. This is regarded as a promising travel mode that could mitigate air pollution. However, because of a lack of quantitative analysis, the environmental benefits of ridesplitting have not been rigorously justified. As vast amounts of observed data of ridesourcing have become increasingly available, this study quantifies the environmental benefits of ridesplitting based on the global positioning system (GPS) trajectory and trip order datasets of DiDi Chuxing in Chengdu, China. First, the saved distances of ridesplitting are calculated by analyzing the travel distances of both ridesplitting trips and the corresponding trips under non-ridesplitting conditions. Then, the emission factors of CO, NOx, and HC are estimated by a localized MOVES model. Combining the saved distances and emission factors, the emission reductions from each ridesplitting trip can be calculated. The results show that ridesplitting can decrease the travel distance by 22% on average compared with non-ridesplitting. As a consequence, the average emission reductions per ridesplitting trip are 10.601 g of CO, 0.691 g of NOx, and 1.424 g of HC, respectively. This study provides a better understanding of the environmental benefits of ridesplitting and theoretical guidance for the government’s decision-making in green transport planning.
