Why has the Montreal Protocol been more successful than the Kyoto Protocol?

The Montreal Protocol has been more successful than the Kyoto Protocol primarily due to its clear, specific target of phasing out ozone-depleting substances, which garnered widespread international consensus and compliance. Additionally, the Protocol's flexibility allowed for adjustments and amendments based on scientific findings, enabling countries to adapt to new information. The economic incentives for developing countries to adopt alternatives and the availability of substitutes also contributed to its effectiveness, while the Kyoto Protocol faced challenges due to its complex commitments and varying levels of participation among nations.
