Editing Montreal Protocol (section)

=== Regional detections of non-compliance ===

In 2018, scientists monitoring the atmosphere following the 2010 phaseout date reported evidence of continuing industrial production of CFC-11, likely in eastern Asia, with detrimental global effects on the ozone layer.<ref>{{cite web|url=https://www.npr.org/sections/thetwo-way/2018/05/17/611984631/banned-ozone-depleting-chemical-is-still-being-produced-somewhere-scientists-say|title=Banned Ozone-Depleting Chemical Is Still Being Produced Somewhere, Scientists Say|publisher=NPR|date=17 May 2018|access-date=17 May 2018}}</ref><ref>{{cite journal|title=An unexpected and persistent increase in global emissions of ozone-depleting CFC-11|author=Stephen A.
