Experts expect that lockdown may lead to biggest CO2 emission fall since the world war 2 this year as the Coronavirus outbreak brings a virtual stand still, according to the team of scientists providing benchmark emissions data .

According to Rob Jackson who chairs the Global Carbon Project and a professor of Earth system science at Stanford University , Carbon output could fall by over 5% year on year - the first dip science since a 1.4% reduction after 2008.

He also said I wouldn't be shocked to see a 5% or more drop in CO2 emission this year , something not witnessed after the world war 2 .

The prediction about CO2 emission fall by climate researchers represents good news in the mid of crisis : Scientists had warned that Global Carbon dioxide emission must start dropping by 2020 to avoid the worst impacts of Global climate change.

Corinne Le Querre a climate scientist at the University of East Anglla said, I expect the emissions will go back close to where they were.

The pattern of swift rebound has begun from China where emissions fell by 25% as the country closed factories and locked down the whole country for the outbreak of Coronavirus pandemic .

A UN report had also found that emissions would have to start falling by by an average of 7.6% per year to give the world a chance to limit the rising global temperature by 1.5% .

Prier Friedlingstein of university of Exeter in England also said, Even if there is a decline in CO2 emission in 2020 by 10% or 20% , it's important from a climate point of view it would be a small dent if emissions go back to pre novel COVID19 crisis level in 2021.
