Introduction: Since the COVID-19 or novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) happened in December 2019, the number of cases has been rapidly increasing. To reducing the speed of infection, nations around the world have been doing movement control order (MCO) to their city for some time. The evidence shows that MCO can help many countries controlling the pandemic. The other effects of MCO is a change in air quality and gas emissions. The current study made for collecting evidence of how MCO affect air quality and gas emissions in several areas. This study aimed to explore if there are any positive and negative effects of movement control order (MCO) to air quality and gas emissions of areas that doing so. Discussion: During the movement control order (MCO) period, human outdoor activities have significantly reduced, affecting industrial operations reduction significantly, transportations, and other activities like constructions that leads to reduction of emissions. But there is increase of O3 and indoor pollution because of household activities increase. Many countries show that there are changes in air quality because of changes in human behaviour during movement control order. Conclusion: Current Studies concludes that the COVID-19 pandemic brings changes in air quality and emissions, as MCO, quarantine, and lighter traffic affect to better air quality outdoor, but, there is also increase of indoor pollutions. It is recommended that human should to maintain air quality by making reduction of unnecessary activities that make air quality worse.

“…The complete lockdown throughout the country had brought major economic disruption in supply chains, tourism, and business travel (Boone et al, 2020;WTO, 2020). Though, the lockdown substantially affected the global economy, disrupt human lifestyle, mental health, as well as the livelihood of the marginal population at large, a positive impact on the environment has also been evident (Lal et al, 2020;Muhammad et al, 2020;Zalakeviciute et al, 2020;Garg et al, 2020;Patel et al, 2020) in the form of recovery, and rejuvenation of various natural processes. The discontinuation of various anthropogenic activities primarily industries and automobiles brought a significant reduction in the level of atmospheric pollution from local (Li and Tartarini 2020;Şahin 2020;Sfîcă et al, 2020;Wan et al, 2020) to global scales (Cadotte, 2020;Sharma et al, 2020;Spinelli and Pellino, 2020) as it linked with global warming, that exuberates climate change (Cushman, 2011;Lahsen, 2008;McLaughlin, 2011 Parry and Carter, 1998;Saikia et al, 2020).…”

Keeping aside the economic consequences, the imposition of strict lockdown in order to break the chain of deadly infection of SARS-CoV-2, has potentially improved the global environmental quality by facilitating a significant reduction in atmospheric pollution. In the present study, the level of atmospheric pollutants in India viz., NO2, AOD, and PM2.5 before and during lockdown 2020 were assessed and compared using standard methods. The study revealed a significant reduction in NO2 i.e., >10% change in 73.71% parts in India along with a high negative anomaly of AOD (<-1.0 in 32.92% parts in India) primarily in the Indo-Gangetic Plains, western, southern, and eastern parts during the lockdown. The five megacities observed a sharp decline in the daily mean concentration of PM2.5 (ca. 32% (Delhi) to 59.62% (Bengaluru) during the lockdown 2020 as compared to the analogous period of lockdown in 2019. The study exhibited the very less contribution of seasonal and meteorological variables in the abatement of pollution during the lockdown period. The findings may be useful in guiding future strategies to maintain environmental quality by adopting a well-planned lockdown strategy.

“…Investigating other areas of Asia, Malaysia's control order also impacted on PM 2.5 pollutant levels. Considering three phases, immediately before the control order (14-17 March) and the first (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31) and second (1-14 April) phases of the order, PM reductions were detected, with the northern region reducing concentrations the most, by 23.7%, exceeded only by areas with high COVID-19 caseloads, which reduced PM 2.5 levels by up to 28.3% [17]. Looking more broadly at South East Asia, a 27-30% reduction in NO 2 levels over the region was identified due to a reduction in anthropogenic and industrial activities, with some variation for seasonal biomass combustion.…”

Short term outcomes of the COVID-19 pandemic have included improved air quality and reduced carbon dioxide (CO2) and other greenhouse gas emissions, while long term repercussions may include a disruption to joint international research efforts, the creation of silos, and the potential for internalizing efforts toward national rather than global goals. In this study, we identified the impacts of reduced mobility on pollutants and emissions, the emergence of nationalist approaches and effects on international cooperation, and how these issues will affect the achievement of global carbon targets and the Sustainable Development Goals (SDGs). COVID-19 presents a global short-term crisis and there is a demonstrated global desire and effort to develop a vaccine and effective treatments. Similarly, climate change is also a near future issue, and as a result we need to reduce CO2 emissions rapidly. This review highlights potential policy interventions, which capitalize on learnings from COVID-19, while identifying SDGs 10, 13 and 17 as critical to engendering a successful, cooperative transition toward sustainability. The recognition of the earth as a closed system, demonstrated by the shared impacts of the COVID-19 crisis, may encourage positive future effects on cooperative approaches toward mitigating climate change, another looming crisis for humanity.
