The Montreal Protocol, established in 1987, marked a significant global commitment to phase out ozone-depleting substances, including chlorofluorocarbons (CFCs). This international treaty led to the replacement of harmful refrigerants with more eco-friendly alternatives, reflecting a growing awareness of environmental issues. The success of the Montreal Protocol has been hailed as a landmark achievement in environmental diplomacy, contributing to the recovery of the ozone layer and setting a precedent for future global environmental agreements.

The phase-out of CFCs and the transition to eco-friendly refrigerants sparked environmental poetry movements, with poets addressing global cooperation and responsibility. This shift in technology inspired a literary dialogue on sustainability and the human impact on the planet.
