May 18 2018 — A real life Dr EVIL is producing thousands of tons of a banned chemical, threatening the recovery of Earth’s badly damaged ozone layer. Scientists believe that industrial amounts of CFC-11 are illegally produced ‘somewhere’ in the Northern Hemisphere, perhaps in Eastern Asia since 2012. Notice the irony. Porton Down and OPCW scientists can trace the origin of a few nano-grams of ‘novichok’ to a Russian laboratory in just a few days. But, after 6 years, nobody has identified the production site(s) of thousands of tons of a life-threatening banned chemical. UPDATE (July 9 2018) — The culprits may have been identified; they are probably Chinese foam companies. Follow us on Twitter: @Intel_Today

UPDATE (February 16 2021) — In a pair of studies published in Nature on February 10 2021, scientists report that atmospheric concentrations of CFC-11 have dropped precipitously since 2018.
China’s Ministry of Ecology and Environment did not reply to several requests for comment.
The analysis published this week, using data from two independent global air-monitoring networks, indicates that concentrations of CFC-11 began to decline more rapidly in 2018. By late 2019, CFC-11 concentrations were dropping by around 1% a year — the fastest pace on record.
In a second paper, Montzka and colleagues used measurements from air-monitoring stations in South Korea and Japan, as well as detailed atmospheric-transport modelling, to show that the largest source of the rogue emissions — in eastern China — has been shut down.
Atmospheric scientists believe that China was responsible for the bulk of these illegal emissions. According to their research, “Around 60% of the global increase came from that region, and 60% of the recent decrease also came from there.”
However, the sources of illegal emissions outside China remain a mystery. They still don’t know where the other 40% was coming from. And they may never find out…
END of UPDATE
According to a study, published in Nature on Wednesday (May 16 2018), the atmospheric level of trichlorofluoromethane — also known as CFC-11 — is not declining as quickly as expected.
Scientists with the US National Oceanic and Atmospheric Administration believe that someone is producing tons of CFC-11, a ozone-depleting chemical banned by the Montreal Protocol. The Treaty was agreed on 16 September 1987, and entered into force on 1 January 1989.
“A simple model analysis of our findings suggests an increase in CFC-11 emissions of 13 ± 5 giga-grams per year (25 ± 13 per cent) since 2012, despite reported production being close to zero since 2006. “
The illicit emissions are probably coming from ‘somewhere in Eastern Asia’, but nothing else is known about the offender.
Based on an analysis of measurements from 12 different sites, the scientists concluded that CFC-11 emissions started to increase after 2012.
The U.N. Ozone Secretariat says it is critical to “identify the causes of these emissions and take necessary action.”
“It is important to note that these findings also highlight the efficacy of the Montreal Protocol, its institutions and mechanisms, with science at their core.
So long as scientists remain vigilant, new production or emission of ozone-depleting chemicals will not go unnoticed.”
Emissions of ozone-eating chemical rising
UPDATE (July 9 2018) — Cheap Chinese home insulation material made mostly for domestic purpose is mostly — perhaps entirely — responsible for the rise.
The Environmental Investigations Agency (EIA) found widespread use of CFC-11 in China, even though the chemical was fully banned back in 2010.
Experts had feared that the rise was the clue of a secret nuclear bombs project [Uranium enrichment plant]. The truth is less dramatic but no less disturbing.
“CFC-11 makes a very efficient ‘blowing agent’ for polyurethane foam, helping it to expand into rigid thermal insulation that’s used in houses to cut energy bills and reduce carbon emissions.
Researchers from the EIA, a green campaign group, contacted foam manufacturing factories in 10 different provinces across China. From their detailed discussions with executives in 18 companies, the investigators concluded that the chemical is used in the majority of the polyurethane insulation the firms produce.
One seller of CFC-11 estimated that 70% of China’s domestic sales used the illegal gas. The reason is quite simple – CFC-11 is better quality and much cheaper than the alternatives.”
Dr Stephen Montzka from the US National Oceanic and Atmospheric Administration (NOAA) told BBC News:
“The pervasiveness of the use of CFC-11 that seems apparent in China based on their survey is quite amazing, although it is hard for me to assess the accuracy of the emission estimate they make to know if it is indeed likely that this activity can explain all or most of what we are observing in the global atmosphere.”
EIA’s calculations show that emission estimates associated with the level of use reported by these Chinese companies explain the majority of these no longer mysterious CFC emissions.
UPDATE (May 23 2019) — A new report, published in the prestigious journal Nature, concludes that Industries in north-eastern China have released about 7,000 tonnes of the Chlorofluorocarbon-11 (CFC-11), into the atmosphere in violation of the 1987 Montreal Protocol.
An international team of atmospheric scientists gathered additional data from monitoring stations in Japan and Taiwan. Their measurements showed ‘spikes’ in pollution when air arrived from industrialised areas in north-eastern China.
“We show that emissions from eastern mainland China are 7.0 ± 3.0 (±1 standard deviation) gigagrams per year higher in 2014–2017 than in 2008–2012, and that the increase in emissions arises primarily around the northeastern provinces of Shandong and Hebei. This increase accounts for a substantial fraction (at least 40 to 60 per cent) of the global rise in CFC-11 emissions. We find no evidence for a significant increase in CFC-11 emissions from any other eastern Asian countries or other regions of the world where there are available data for the detection of regional emissions.”
When CFCs break down in the atmosphere, they release chlorine atoms that are able to rapidly destroy the ozone layer which protects us from ultraviolet light. A gaping hole in the ozone layer over Antarctica was discovered in the mid 1980s.
CFCs are also very potent greenhouse gases. One tonne of CFC-11 is equivalent to around 5,000 tonnes of CO2.
The 7,000 tonnes of CFC emitted by the Chinese factories equate to about 35 million tonnes of CO2 being emitted into the atmosphere every year. This is about 4 times the annual CO2 emissions of Luxembourg and one third of Belgium emissions.
PS: I would like to point out that it took one year for an international team of scientists to pinpoint the source of the emission of 7,000 tonnes of a banned chemical.
Yet, according to UK Prime Minister Theresa May, the British Intelligence Services were able to identify in 48 hours the Russian laboratory having produced a few nano-grams of the Novichok allegedly used in the poisoning of Sergei Skripal and his daughter.
