Ann Arbor (Informed Comment) – The International Energy Agency issued a report this month that contains a kernel of significant hope for halting the poisoning of the earth by carbon dioxide emissions.
The IEA found that emissions from the advanced economies actually fell in 2023, although global emissions increased slightly, by 1.1%. The report says, “After falling by around 4.5% in 2023, emissions in advanced economies were lower than they were fifty years ago in 1973.”
Emissions have fallen in the advanced economies before, as with the 2020 COVID pandemic, the 2008-2009 deep recession, and during economic downturns in the 1970s and 1980s.
The reason the new findings are so heartening, however, is that in 2023 emissions from the advanced economies fell even though they experienced economic growth. A 4.5% fall in emissions from countries with an expanding GDP is unprecedented in the hydrocarbon era. The advanced economies grew by 1.7%.
The fall in emissions would have been even greater, but drought in China and elsewhere caused hydroelectric production to fall last year. This finding should reinforce for us how, the longer we leave the climate crisis unsolved, the harder it becomes to solve it.
This finding is a slap in the face to figures such as past COP chairman Sultan Ahmed al-Jaber of the United Arab Emirates. In a testy exchange with Mary Robinson, chair of the Elders, last fall, Al-Jaber said, “Please help me, show me the roadmap for a phase-out of fossil fuel that will allow for sustainable socioeconomic development, unless you want to take the world back into caves.”
Mr. Al-Jaber, meet the IEA. In 2023, the advanced economies grew and developed, but they cut their carbon dioxide production by over 4% nevertheless. And that is the future of the world. Petroleum will still have a value, for instance in petro-chemicals such as fertilizer, but it will increasingly not be burned for fuel to power vehicles.
Carbon dioxide emissions are produced in lots of ways, from burning gasoline in vehicles, from heating homes and businesses, and from electricity production. Some 2/3s of the reduction in CO2 last year took place in the electricity sector. This is a testament to the vast build-out in the US, Europe, and China, of wind and solar power. Renewables accounted for over a third of electricity generation in 2023.
At the same time, coal fell to only 17% of electricity production. Coal is the dirtiest fossil fuel and needs to be phased out entirely. Some coal was replaced instead by fossil gas, which isn’t as good, but still cuts CO2 emissions by half. Replacing coal with solar and wind would cut them to almost zero.
A piece of very good news is that coal use in the advanced economies has fallen to 1900 levels. That is still way too high– we need to get back to 1750 and drop coal entirely. But it is a remarkable accomplishment compared even to a decade ago.
The figures for Europe are even more striking. There, CO2 emissions were reduced by nearly 9% last year! These countries, however, experienced weaker growth than the average of the OECD, at 0.7%. In Europe, fully half of the decline of carbon dioxide output was owing to growth in clean energy.
One takeaway from the finding that emissions fell in advanced countries but still rose by a percentage point globally is that the wealthier nations must now increasingly invest in green energy in the developing world. The climate doesn’t care where you live. The moment we hit 2.7° F. above the preindustrial average, there is some reason to think that there will be an immediate big crop failure. Greening our global energy isn’t an abstract ideal. We have to do it to keep our children and grandchildren from starving or becoming climate refugees.
