IEA's latest Global Energy Review predicts that energy-related carbon-dioxide emissions will rise by 1.5 gigatonnes to 33 gigatonnes in 2021, an increase of almost 5% - the largest since 2010 following the global financial crisis 2007-2009 as governments invested on carbon-intensive projects to pick up their economies. If this prediction is proven then it will be a clear warning that the economic recovery from the COVID crisis is unsustainable for our climate.
