The Vienna Convention for the Protection of the Ozone Layer and the Montreal Protocol on Substances that Deplete the Ozone Layer logo was developed to provide a distinct brand for the two treaties across various communication assets and applications. The visual identity guideline is designed to provide a comprehensive overview of applications and correct use of the logo.

2013 HCFC-22 22.9 MT China A person was accused in 2017 of entering into an agreement with a Chinese company to purchase HCFC-22, which was packaged in cylinders bearing counterfeit trademarks. The 2013 contract listed the product as R-134a – but a second, secret agreement called for the company to actually sell HCFC-22. The indictment charged the accused with conspiracy, one count of entry of goods by means of false statement, five counts of passing false and fraudulent papers through a customhouse, one count of smuggling and one count of violating the Clean Air Act by improperly selling HCFC-22 to an undercover agent. In 2018 the accused pleaded guilty of charges of illegally importing ODS. He was ordered to pay a fine of $40,000 and sentenced to a term of two years’ probation, to include 6 months of home confinement.

This document aims to initiate a discussion on gender mainstreaming in the work of the ozone treaties. It begins by providing a brief overview of international instruments on gender and the 2030 Agenda, to which the parties’ implementation of the ozone treaties has over the years made significant contributions. The 2030 Agenda clearly acknowledges the link between environmental protection and gender equality: Sustainable Development Goal 5 (SDG5) is aimed at achieving gender equality and empowering all women and girls, and gender-related aspects are present within several other goals as well.

2015 HCFC-22 CFC-12 Not specified Trans-shipment from China to Russia via Netherlands In July 2015 the Dutch Environmental Inspectorate has blocked in the Port of Rotterdam 2 containers with gas bottles containing refrigerants for further transport. From samples taken from the refrigerants it was shown that, despite their labelling as HFC’s (R-134a and R-407c) the bottles contained partly HCFC-22 and CFC-12 Legislation According to the European Ozone Regulation (EC) No 1005/2009 and related Dutch national legislation such import of Ozone Depleting Substances is illegal and this ban on import is broadly formulated addressing everyone involved. The Council of State of the Netherlands determined that in addition to the sender and receiver also a shipping company can be considered as offender of a legal ban on imports of ozone-depleting substances. Cease and desist order. The Environmental Inspectorate considered all parties involved in this case as offenders and the Chinese supplier, the Russian addressee as well as the shipping company were all imposed with cease and desist orders requiring full destruction of all illegal ODS refrigerants and payment of storage costs conditional to a penalty. Eventually the shipping company appealed to this cease and desist order. Shipping company’s view The company’s position was that they were wrongly addressed as offender in this case and could not be blamed as they must be able to rely on the accuracy of the product information provided by the other parties involved. It cannot be expected from them to check the content of all gas bottles. They are suffering from the actions of the Chinese and Russian parties. The Ruling In its Ruling no 201706000/1/A1 from April 25, 2018, the Netherlands Council of State did not agree and puts the Environmental Inspectorate in the right. The import ban is also targeting a shipping company which can be therefor also considered as offender. Furthermore, from a professional carrier some research into the contents of the bottles can be expected. The Council of State also found important that it was a known smuggling route of ozone depleting substances. Furthermore, the carrier could check the gas cylinders in a relatively easy way through sampling. Importance This ruling is important because it facilitates the approach to address this kind of international smuggling activities. There are also more of this kind of broadly formulated prohibitions. So also for other areas this statement is of interest. Carriers will have to take their responsibilities and be more active in preventing violations of this kind of import bans.
