Has the ratio between GDP growth and CO2 emissions improved over time?

H ope of meeting the climate goals without there being a significant decline in living standards rests on whether the ratio between growth and CO 2 emissions ( in OECD countries, emerging countries and globally) has improved over time (a given rate of growth has resulted in lower C O 2 emissions). Comparing the 1980 s , 1990 s , 2000 s and 2010 s , we find that: Everywhere, a fall in GDP growth reduces CO 2 emissions growth more than in the past; This means that the climate goals can be met with a smaller loss of growth than in the past: growth would now have to fall to 0.4% in the OECD ( from 2.2% growth in 2018), 2.4% in emerging countries ( from 4.8% growth in 2018) and 2.2% for the world ( from 3.7% growth in 2018).
