Mysterious source of illegal ozone-killing emissions revealed, say investigators • The Guardian
Damian Carrington on the followup to <a href="https://theoutline.com/post/4708/montreal-protocol-vienna-convention-noaa-nasa-ozone-layer-hole-cfc">the story which first surfaced in May</a>:
<p>The Environmental Investigation Agency, a non-governmental organisation, <a href="https://eia-global.org/blowing-it">has now identified widespread use of CFC-11 factories in China</a> that make insulating foams. The EIA’s investigators identified factories that sold the chemicals needed for foam-making, then contacted and visited them.

“We were dumbfounded when out of 21 companies, 18 of them across China confirmed use of CFC-11, while acknowledging the illegality and being very blase about its use,” said Avipsa Mahapatra at the EIA. Furthermore, the companies said the use of CFC-11 was rife in the sector. “It was very clear. These companies, again and again, told us everybody else does this,” she said.

China is a major producer of the rigid polyurethane foams involved and the EIA calculates that if the illegal use of CFC-11 is pervasive in the 3,500 small- and medium-sized companies that make up the sector, then this would explain the surge. Without action, the CFC-11 emissions would delay the recovery of the planet’s ozone hole by a decade, scientists estimate.

“We didn’t know what on Earth someone would be using CFC-11 for – well, here’s one answer and that’s a surprise,” said Steve Montzka at the US National Oceanic and Atmospheric Administration in Colorado, whose team revealed the surge. “Despite efforts to get rid of this activity, it continues.”</p>


This - too - is why regulation, and enforcement of regulation, matters; and why kneejerk calls to "cut red tape" are foolish. Red tape has a purpose, even if it's inconvenient.
