Global greenhouse gas emissions have fallen by a record amount due to the coronavirus pandemic, according to a study published in scientific journal .
The decline in economic activity and global travel has reduced emissions by 2.5 gigatonnes of CO2e (a measurement that converts all greenhouse emissions in CO2 terms).
That adds up to 4.6% of the world's usual annual total.
The drop is five times bigger than the decline produced by the financial crisis of 2007-2008, which led to the Great Recession.
Emissions from economic behemoths China, the US, and Germany have dropped the most, followed by four of the largest other countries: Australia, Russia, Indonesia, and India.
