Furthermore, the systems potentially allow rapid CO2 emissions reduction; however, with already low-carbon electricity of France by nuclear power, CO2 abatement (0. 020 kgCO2kWh-1 reduction from 0. 063 kgCO2kWh-1) by PV + EV system can be limited, in comparison to that (0. 270 kgCO2kWh-1 reduction from 0. 352 kgCO2kWh-1) of Kyoto, also because of the Paris low insolation and high demands in higher latitude winter.

It has been claimed that COVID-19 public stimulus packages could be sufficient to meet the short-term energy investment needs to leverage a shift toward a pathway consistent with the 1. 5 degrees C target of the Paris Agreement.

That even substantial world-wide lockdowns of activity led to a one-time decline in global CO$_2$ emissions of only 5. 4% in one year highlights the significant challenges for climate change mitigation that we face in the post-COVID era.
