Global emissions are expected to drop by roughly seven percent this year compared to what was recorded in 2019. That's equivalent to roughly 2.4 billion tons of carbon dioxide.
This, according to Phys.org, is an unprecedented drop because of the "slowdown in economic activity linked with the COVID-19 pandemic."
To put this into perspective, the report said, the Global Financial Crisis in 2008 saw a decline of 1.5 percent in global emissions, comparing it with the 2007 report. The emissions this year is said to be four times larger.
These findings are exhibited in the 15th global carbon budget, a yearly report card on the resources and eliminations of carbon dioxide, of the Global Carbon Project. CO2 is the main driver of climate change caused by humans.
Huge Decline
This latest development may seem promising news although experts say the world cannot celebrate just yet. A quick bounce-back of emissions to levels of pre-COVID-19 is likely, probably by as soon as 2021.
Recent research recently found that emissions in China snapped back to more than the levels of last year, during late spring when economic activity started to go back to normal.
Such findings came out prior to the Climate Ambition Summit on Saturday, where worldwide leaders are set to demonstrate their commitments to climate initiatives five years from the Paris Agreement.
This huge decline in emissions need to be considered as a unique opportunity to divert emissions growth's historical course for good.
Emissions in This Year's Pandemic
The global fossil carbon dioxide emissions in all, for this year, are approximated to be roughly 34 billion tons of CO2.
Approximated emissions at the start of this month are lower than last year's levels, at least in the fields of transportation. Nevertheless, emissions have been said to be "edging back up since the peak global daily drop" of 17 percent in early April.
The drop in emissions this year was specifically steep in the United States at 12 percent, and European Union at 11 percent, where emissions were already dropping even before the pandemic, mainly from a decrease in the use of coal.
Essentially, worldwide, the transport sector has contributed the most to the emission drop this year, specifically cars, vans, and trucks.
At the peak of these pandemic lockdowns, the normal levels of transport emissions were cut by roughly 50 percent in many countries, including the US and Europe.
Global Emissions
Global emissions, in general, have increased by 61 percent since 1990. However, this growth's pace has varied. At the beginning of the 1990s, the growth in emissions slowed down because of the former Soviet Union's collapse.
However, it then increased quite rapidly during the 2000s, by three percent every year on average. This was partly because of China's rise as an economic power.
For the last ten years, though, the paces of emission started to slow down again, with a rise just below one percent each year. More so, emissions last year did not grow much, if at all, when compared to the other year.
This global health crisis, along with other recent trends such as the shift to clean energy, have placed the world at a crossroad: the choices people make at present can change the course of global emissions.
On top of the slowdown in global emissions in recent years, the drop this year, there are currently many countries pledging to achieve net-zero emissions by the middle of the century or even soon after.
