In the year 2015, world leaders signed the Paris Climate agreement, promising collaborative effort from all nations to curb carbon emissions. Four years later, in 2019; global carbon dioxide emissions hit an all time high–of more than 35 giga tonnes.
The next year, the world was struck with a health emergency, the COVID- 19 pandemic gripped all the countries during the first half of 2020. Lockdowns and supply chain disruptions caused the carbon emissions to fall by a remarkable 9%, emissions came down to about 33%.
Climate scientists have been studying the trajectory of global emissions and how it was affected by the pandemic. 2019 was projected to be the year after which emissions would go down slowly as the major polluting countries are switching rapidly to renewable sources of energy. But last year's report from Carbon Monitor reported emission of 34.8 giga tonnes of carbon which is just shy of pre pandemic levels.
This has put a pause to the expectation that fossil fuels are slowly starting to wane out of use, they sure will go out of use but just not yet..
