That’s a wrap on #OEWG47 of the #MontrealProtocol🌍 Heated debates over funding, PFAS and TFA pollution and feedstock chemicals. Lacklustre attention to reforming the institutions of the Montreal Protocol to make the best treaty even better. Lots to do before #MOP37 #HFCphasedown #Cooling #OzoneLayer
