The Clean Development Mechanism (CDM) under the Kyoto Protocol aims to help countries achieve sustainable development. A study analyzed CDM data from 58 countries between 2005-2010 to see if it actually promotes sustainability. The researchers used a smart method to track changes over time. The research shows that CDM projects do make a positive impact on sustainable development in host countries. This study shines a light on how CDM contributes to global sustainability, offering important insights for developing nations and those using market tools.
