Potential reduction of CO2 emissions which is the cause of greenhouse gases during COVID-19

Abstract

Background: The implementation of education in tertiary institutions contributes significantly to greenhouse gas emissions, particularly carbon dioxide (CO2), which causes the greenhouse effect and global warming. The Intergovernmental Panel on Climate Change (IPCC) identifies transportation, energy supply, and industry as the primary sectors driving CO2 emissions over the past 30 years. However, the COVID-19 pandemic unexpectedly reduced CO2 emissions globally by up to 70% due to restricted activities. In 2020, the pandemic led countries, including Indonesia, to enforce Large-Scale Social Restrictions (PSBB) to curb virus spread, which significantly limited community mobility and vehicle use. Climate change, driven by greenhouse gas emissions, is a critical development challenge for Indonesia. Method: The study uses various calculation methods from journals and websites, incorporating expert opinions and the IPCC's method, to analyze emission reductions. Findings: The findings indicate that the COVID-19 pandemic and associated lockdowns reduced CO2 emissions due to decreased fuel consumption and mobility. Conclusion: This period highlights opportunities for strategies like low-carbon development to continue reducing emissions from vehicles. Novelty/Originality of this Study: This study provides a novel contribution by quantitatively assessing CO2 emission reductions during the COVID-19 lockdown, emphasizing the unique context of an unprecedented global event. It conducts a comprehensive literature review to integrate various CO2 calculation methods, particularly highlighting the sophisticated IPCC method, and offers a comparative analysis of emission reduction techniques.
