Study: Global Carbon Emissions Drop 17% Amid Pandemic

A study published in Nature Climate Change reveals that global CO2 emissions dropped by nearly 19 million tons during the peak of COVID-19 lockdowns in April, reaching levels not seen since 2006. The reduction was mainly due to decreased traffic. The US saw a significant cut in emissions, especially in California and Washington. However, this decline is expected to be temporary as restrictions ease. Researchers predict a 4-7% decrease in global emissions for 2020 compared to 2019, depending on the duration of restrictions and the return to normal activities.
