As one of the sectors most vulnerable to the Covid-19 pandemic, aviation saw the steepest reduction in emissions (-64.1%). The power sector witnessed a 14.9% decrease, reflecting both reduced electricity consumption due to the pandemic and previously identified decarbonisation trends. These include both the switch from coal to natural gas-fired power generation, and the replacement of fossil fuels by renewable energy sources.
Emissions from industry decreased by an average of 7%, with reductions observed in most sectors, including iron and steel (-11.7%), cement (-5.1%), chemicals (-4%) and refineries (-8.1%). However, with current data, it is not yet possible to determine what proportion of these reductions is due to increased emissions efficiency.
