Carbon emissions are among the main causes of environ-mental problems, air pollution and global climate change that are beginning to be felt intensely in the 21st century. The causes of the increase of carbon and greenhouse gas emission are the factors origi-nating from industrialization and urbanization. Air pollution and global climate change, which develop due to the increase in carbon emissions and greenhouse gas emissions, are also considered as some important public health problems. These effects on health are among the main reasons for the regulation of international environmental agreements and summits. In the early process of Covid-19pandemics, especially in countries with a high pollutant industry such as industri-al areas of China to stop production for a few months caused reducing carbon emissions in these countries and the meteorological findings have revealed data on the increase of air quality. The aim of this study is to discuss how the Covid-19 pandemic process affects environmen-tal problems, particularly in reducing carbon emissions. In this study, a literature-based research method has been used over current publica-tions. Literature findings show that even during the Covid-19 pandem-ic, countries are not able to reduce targeted carbon emission levels to the expected level. Nevertheless, in the pandemic process, the positive effects of the reduction of carbon emission on the nature and air quali-ty were concretely seen. Countries' considering this information in their future decisions whether it will create hope for a healthy future or not is a matter of debate.
