“In 2020, when the coronavirus pandemic was raging, CO2 emissions declined, but unfortunately, they have returned practically to the same level as the 2019 figures,” Chung told the Nobel Vision forum in Moscow. “What we saw was only a temporary change for the better. The increase in emissions resumed very quickly. Not only that, there are suggestions that they will rise further.”
Chung said major countries had to undertake more decisive efforts than those already made public in order to bring down greenhouse gas emissions.
“Measures to limit temperature increases to 2 degrees Celsius must be radical in nature,” he said. “In order to achieve the aim of keeping global warming to within 1.5 degrees, it is vital to keep the effect on the environment to 6 % every year. Even the pandemic didn’t help us much and resulted in a reduction of only 5 %.”
