Residents in many of the ASEAN’s most polluted cities have been delighted to observe significant decreases in pollution levels as a result of COVID-19 lockdown measures that have disrupted the economy and thus many pollution-causing activities…Indeed, global data from late May shows an all-time high for levels of CO2 as countries start reopening their economies. However, with all the tragedy caused by the COVID-19 pandemic, perhaps there can be a silver lining in terms of how we navigate ASEAN’s energy transition if we can embrace renewable energy and clean technologies. COVID-19 seems to be accelerating the adoption of several pre-pandemic trends like digitization and robotics. Perhaps decarbonization can be another. The post-COVID-19 economic recovery will drive increased energy demand. ASEAN’s energy mix greatly relies on fossil fuels which are a significant source of emissions. To ensure the region’s energy sustainability, development and healthy environment, this rapid increase in demand will need coordinated management and appropriate energy supply infrastructure and investment.
