There is a strong link between economic activity and global carbon dioxide emissions, due to the dominance of fossil fuel sources of energy. This coupling suggests we might be in for an unexpected surprise due to the coronavirus pandemic: a slowdown of carbon dioxide emissions due to reduced energy consumption.
The effect is likely to be less pronounced than during the global financial crisis (GFC). And emissions declines in response to past economic crises suggest a rapid recovery of emissions when the pandemic is over.
But prudent spending of economic stimulus measures, and a permanent adoption of new work behaviours, could influence how emissions evolve in future.
The GFC experience indicates that the carbon efficiency of the global economy may improve much more slowly during a crisis. If this happens in 2020 because of the coronavirus, carbon dioxide emissions still could grow.
Structural changes may happen, such as the shift to nuclear energy after the oil crises, but evidence suggests emissions continue to grow.
There is an opportunity to invest the stimulus money in structural changes leading to reduced emissions after economic growth returns, such as further development of clean technologies.
Also, the coronavirus has forced new working-from-home habits that limit commuting, and a broader adoption of online meetings to reduce the need for long-haul business flights. This raises the prospect of long-term emissions reductions should these new work behaviours persist beyond the current global emergency.
