The parties to the Montreal Protocol amended the protocol to allow, among other things, the control of new chemicals and the establishment of a financial mechanism to allow developing countries to comply. The Montreal Protocol also contains a unique adaptation provision that allows the parties to the protocol to react quickly to new scientific information and agree to accelerate the reduction of chemicals already covered by the protocol. These adaptations will automatically apply to all countries that have ratified the protocol. Since then, the Montreal Protocol has been strengthened several times by the control of additional ozone depletion substances (SOOs) and by the postponement of the date when already regulated substances must disappear. In addition to the adaptations and amendments to the Montreal Protocol, the parties to the protocol meet annually and make a series of decisions to enable the effective implementation of this important instrument. The Montreal Protocol on Ozone Depleting Substances is a 1987 international agreement. It was designed to stop the production and importation of ozone-depleting substances and reduce their concentration in the atmosphere to protect the planet`s ozone layer. The same international agreement, which has succeeded in putting the ozone layer on the road to recovery, is now being used to combat climate change. The key to the rapid transition to the gradual exit of the masters has been the broad acceptance of the seriousness and urgency of the problem by public opinion, economic actors and world leaders; a consensus forged after the discovery of the ozone layer in 1985.
However, the negotiations on the Montreal Protocol still had to deal with the competing national interests of the governments concerned in order to reach an agreement. The United States, which played a leading role in the negotiations, was largely influenced in its position by its commercial interests, which opposed a ban until 1986, when the company, duPont, which successfully plays the world`s largest role in the production of CFCs, successfully developed alternative chemicals. It was from that point on that the United States took the lead in insisting that it be banned.
