“I see no benefit from the coronavirus. If greenhouse emissions fall temporarily, good, but there will only be a significant drop in the event of a recession. Nobody wanted that in 2008, and nobody wants it now.”

Governments should act with the same urgency on the climate as on the coronavirus, leading campaigners say, as evidence states that the health crisis is reducing carbon emissions more than any policy.
The deadly virus outbreak, which has killed more than 4,000 people and infected more than 116,000 people, has raised global alarm. However, unlike the response to global warming, it has shown how political and business leaders can take radical emergency measures on the advice of scientists to protect human well-being.
In China - the source of the disease and the world's largest carbon emitter - the actions of the authorities have accidentally shown that sharp 25% carbon dioxide cuts can bring less traffic and cleaner air with only a small reduction in economic growth, according to a study of Carbon Brief.

If this trend continues, analysts say that it is possible this will lead to the first drop in global emissions since the financial crisis of 2008-2009. Even a slowdown in CO2 could save time for climate action and, more importantly, behavioral changes at long term can inspire, especially in travel

Global air traffic fell by 4.3% in February due to cancellations of tens of thousands of flights to affected areas.But Rob Jackson, the president ofGlobal Carbon Project,said that this would only make sense if it led to long-term behavioural change, especially in aviation, which is one of the fastest growing source of emissions.

Coronavirus can lead to reduction in global CO2 emissions
