Carbon dioxide emissions and environmental risks: Long term and short term

The world is currently experiencing the environmental challenge of global warming, necessitating careful planning of carbon dioxide (CO2CO₂) emissions to deal with this problem. This study examines the environmental challenge posed by CO2CO₂ emissions from both a long and short-term perspective. In the long term, despite efforts made by countries, our change-point detection analysis shows that there has been no structural change in CO2CO₂ emissions since 1950. Without significant efforts, the carbon budget corresponding to the Paris Agreement's target will be exhausted by 2046. To achieve this target, a significant reduction in global CO2CO₂ emissions of 3. 22% per year is necessary. In the short term, COVID-19 is thought to have relieved pressure on CO2CO₂ emissions. However, this study shows that CO2CO₂ emissions quickly returned to normal levels after a brief downturn, and we provide information on the order of CO2CO₂ emissions recovery for different sectors.
