How does the Montreal Protocol handle substances with higher ODP values?

The Montreal Protocol treats substances with higher Ozone Depletion Potential (ODP) values more stringently because these substances have a greater capacity to deplete the ozone layer. The protocol specifically aims to reduce and eventually eliminate the use of these harmful substances to protect the ozone layer and, by extension, human health and the environment.

Substances with higher ODP values are prioritized for quicker phase-out schedules. This approach reflects the urgency in addressing their impact on atmospheric ozone levels. By accelerating the elimination of these substances, the protocol seeks to mitigate the ongoing depletion of the ozone layer and alleviate the associated environmental and health concerns.

In contrast, substances with lower ODP values are subject to less intense regulations or longer timelines for phase-out, as their impact on ozone depletion is comparatively lower. This structured approach allows for a focused and effective response to the most damaging substances while allowing for more manageable transitions for those that are less harmful.
