And while South Africa may have topped the overall pile of major economies in 2022, the trajectory of its carbon intensity has been steadily lower for the past decade, with the latest carbon intensity level nearly 8% lower than that of 2010.
Poland's carbon intensity is also on a steadily declining track, and has dropped 16% since 2010 due to greater use of renewables and cleaner-burning natural gas in energy generation.
Carbon intensity of key Asian economiesIndia, which had a carbon intensity of 632 grams per KWh in 2022, also has a declining intensity trend, although at a much shallower slope than Poland given India's continued high reliance on coal in power generation.
TRENDING LOWEROther key economies with significant carbon intensity trends include Japan, which was forced to sharply increase carbon intensity in the wake of the 2011 Fukushima nuclear meltdown by shuttering other nuclear plants and increasing use of coal and gas-fired plants to generate electricity instead.
Some economies are increasing their carbon intensity, but most have reduced intensity since 2010Most other major economies are also undergoing steady carbon intensity declines, including Australia, which in the early 2000's had one of the highest carbon intensity ratings in the world thanks to its predominantly coal-fired power system, but has now cut that intensity through sharp increases in solar and wind power generation.
