The video discusses carbon tetrachloride, a greenhouse gas regulated by the Montreal Protocol. Despite global bans, emissions were detected between 2007 and 2012, contradicting official reports. The chemical's lifetime is longer than previously thought, affecting its atmospheric removal rate. The source of emissions remains unknown, necessitating further research.
