The average emission-intensity of power generation in 2019
was "lower than all but the most efficient gas-fired power plants", according to the IEA.
This is not the first time energy related emissions have plateaued.
Between 2013 and 2016 they hovered around 32.2bn tonnes a year,
before rising again in 2017 as the use of coal to fuel developing economies increased.
This previous plateau was accompanied by excited declarations that such emissions had peaked.
Similar comments have been made this week, perhaps also prematurely.
In addition to changes in coal use, a sluggish economy may have played a part
and the data show that milder than usual weather caused a perceptible drop
in emissions from several countries with large, carbon-hungry economies.
The news is also tempered by the latest data from the Amazon rainforest.
This, one of the world's largest woodlands, has acted historically as an absorbing sponge for CO2
by removing it from the atmosphere through photosynthesis.
Researchers at Brazil's National Institute for Space Research have shown that a vast part of the south-east of the Amazon,
about one fifth of its area, has lost its ability to soak up the gas and is now a net source of emissions into the atmosphere instead.
This land has been widely deforested, so the result is little surprise. But it is disappointing.
