China cooks the carbon accounting books by 400 million tons
China treats us like mugs and we cheer it on, says Jo Nova. Almost no one cares that the largest emitter on Earth has gaping holes in its CO2-numbers.
One reader in The Wall Street Journal, pointed out that The Onion saw it coming years ago:
“China Vows to Begin Aggressively Falsifying Air Pollution Numbers.” (2014)
We live in an era where satire became the news.
The Paris Agreement allows everyone to set their own targets, and to define their own terms (and retrospectively as well). So China decided it would count ‘carbon intensity’, rather than carbon output. But it didn’t define carbon intensity. Normally it means the amount of CO2 emitted per unit GDP — which would work well for China with its rapidly growing economy. But something else is going on.
In the last five years China had promised to cut emissions by 18%, but all the official statistics suggested it was only getting 12% of the way there. Then a miracle happened and suddenly China leapt to a 17.7% reduction, just in the nick of time.
The Ecoworriers team at Carbon Brief are probably the only ones who do care and they drilled through all the detail. But being as generous as they can, even they can’t explain where 380 megatons went.
To put that in perspective, Australia’s entire annual emissions was 459 megatons. It’s like someone just said Oopsie to 80% of our national emissions.
So the rules are loose, and China is taking advantage of every loophole. The CCP knows that the UN isn’t going to turn up with guns to say ‘pay up’. But there is a price. The whole renewables project that China profits from looks just that much more dodgy, and so does the CCP. Who can trust anything they say?
China Cooks the Carbon Emissions Books
The Editorial Board, Wall Street Journal
Unlike the West’s green radicals, China isn’t willing to sacrifice its economy to meet its climate pledges. But Beijing isn’t above cooking its carbon books to gull Western activists into thinking it is.
At United Nations climate conferences in Copenhagen in 2009 and Paris in 2015, Beijing vowed sizeable reductions in the amount of carbon China emits per dollar of gross domestic product, or carbon intensity. Subsequent national planning documents reiterated this goal.
Old-style accounting implies China’s emission grew by a huge 1,430 megatons in the last five years. But the new carbon-intensity figures imply only 690 megatons of CO₂ growth, creating a 730 megatons from CO₂ gap.
China’s new carbon metric leaves Germany-sized gap in its emissions
By Lauri Myllyvirta, Carbon Brief
A major change in the way that China measures its core climate goal has effectively halved the growth in the country’s carbon dioxide (CO2) emissions over the past five years.
Here’s one slight of hand — only coal burnt in pursuit of energy counts. Not coal converted to plastics, asphalt, rubber, chemicals or fertilizer.
A footnote in China’s latest statistical communique offers a brief description of carbon intensity as relating to the CO2 emissions from “energy activities and industrial production”.
This indicates that the carbon-intensity calculation now includes industrial process emissions and excludes non-energy uses of fossil fuels.
Remember China’s huge coal-to-liquids program that I wrote about two months ago? Every year nearly 400 million tons of coal are converted to fertilizer, chemicals, plastics, jet fuel and diesel.
And some of these accounting tricks make sense. The Tupperware containers for example, are legitimately holding their CO2 (for now). But even that trick doesn’t account for the missing CO2.
So China treats us like mugs and we cheer it on. Why?

AI accurately reconstructs temperatures across Antarctica
Artificial intelligence is increasingly being applied in climate science, with mixed results so far. A new study, however, suggests that deep learning can successfully reconstruct Antarctic surface temperatures despite limited observational data. By combining sparse measurements with reanalysis datasets, the researchers claim to achieve high accuracy—offering new insights into long-term temperature trends across the continent.
Clintel President Václav Klaus warns: “No radical change in Europe in the near future”
We must not be naïve optimists about climate policy and should not overestimate the recent positive signals, like those from President Trump. This is the view of Clintel President Václav Klaus: “Nothing has changed in the European Union. We, with a background in the social sciences, cannot imagine that any radical change will take place in Europe in the near future.” Klaus made these remarks in his speech at the annual meeting of the Norwegian Klimarealistene in Oslo on March 15.
New study finds low CO2-sensitivity again
A new paper by Frank Stefani compares solar variability and CO₂ emissions as drivers of global sea surface temperatures. Using the solar aa geomagnetic index alongside CO₂ data, the study estimates a transient climate response (TCR) of about 1.1–1.4 K, near the lower end of the IPCC range. The results align closely with other observation-based estimates and highlight the continuing scientific debate about the relative roles of solar activity and greenhouse gases in recent climate change.
