Graphical abstract As addressed by many studies, greenhouse gas has a significant impact on the different aspects of life and more importantly on the whole environment. The excessive emission of green gas leads to climate change which is regarded as one of the most significant challenges of 21 century. Hence, in this regard, this paper has addressed the changing greenhouse gas (GHG) emissions in 18 countries of the MENA region. For this purpose, ten different scenarios of this disease's future status and its restrictions were considered in an input–output modelling framework. The empirical results indicated that the emission of greenhouse gas is reduced under all scenarios. However, some countries experience more reduction due to the restriction because of COVID-19 like Syria, Iran, Yemen and Lebenon. Based on the ninth scenario, Iran and Syria have the highest reduction in emission of greenhouse gas by 13.1 and 13.8 per cent, and based on the tenth scenario, Lebenan and Syria will experience the highest reduction in emission by about 13.1 and 17.9 per cent. The results show that according to scenario 10 (explosive intensification of the pandemic without the wave subsiding over a while) and scenario 9 (the pandemic worsens step by step without subsiding over a while), Syria and Iran have the highest reduction in greenhouse gas emissions, respectively. According to scenario 1 (rapid and complete control of disease), Bahrain, Qatar, and Kuwait have the lowest reduction in GHG emissions. Besides, the study draws several fruitful implications regarding environmental concerns as sectoral analysis such as Hotels and Restaurants , Retail Trade , Fishing , Wholesale Trade , and Transport sectors. Moreover, policymakers should be alert that notwithstanding all limitations, Private Households and Public Administration develop their emissions during the pandemic since quarantine intensifies the supply of these services. Surprisingly, none of the policy restrictions have a significant impact on GHG emissions from Education, Health, and Other Services , Petroleum , Chemical, and Non-Metallic Mineral Products , Textiles and Wearing Apparel , and Re-export & Re-import , demonstrating the robust and established nature of these sectors' activities. To control the emissions of the quarantine-neutral sectors, long- and mid-term structural and environmental policies should be considered. The researchers are guided by the novel implications in terms of how various industries might reduce emissions in different ways.

At the end of 2019, a novel coronavirus COVID-19 emerged in Wuhan, China, and later spread throughout the world, including Iraq. To control the rapid dispersion of the virus, Iraq, like other countries, has imposed national lockdown measures, such as social distancing, restriction of automobile traffic, and industrial enterprises. This has led to reduced human activities and air pollutant emissions, which caused improvement in air quality. This study focused on the analysis of the impact of the six partial, total, and post-lockdown periods (1st partial lockdown from March 1 to16, 2020, 1st total lockdown from March 17 to April 21, 2nd partial lockdown from April 22 to May 23, 2nd total lockdown from May 24 to June 13, 3rd partial lockdown from June 14 to August 19, and end partial lockdown from August 20 to 31) on the average of daily NO 2 , O 3 , PM 2.5 , and PM 10 concentrations, as well as air quality index (AQI) in 18 Iraqi provinces during these periods (from March 1st to August 31st, 2020). The analysis showed a decline in the average of daily PM 2.5 , PM 10 , and NO 2 concentrations by 24%, 15%, and 8%, respectively from March 17 to April 21, 2020 (first phase of total lockdown) in comparison to the 1st phase of partial lockdown (March 1 to March 16, 2020). Furthermore, the O 3 increased by 10% over the same period. The 2nd phase of total lockdown, the 3rd partial lockdown, and the post-lockdown periods witnessed declines in PM 2.5 by 8%, 11%, and 21%, respectively, while the PM 10 increases over the same period. Iraqi also witnessed improvement in the AQI by 8% during the 1st phase of total lockdown compared to the 1st phase of partial lockdown. The level of air pollutants in Iraq declined significantly during the six lockdown periods as a result of reduced human activities. This study gives confidence that when strict measures are implemented, air quality can improve.
