The Protocole de Kyoto is an international agreement aimed at reducing greenhouse gas emissions to combat climate change. Adopted in 1997 and effective from 2005, it commits industrialized countries and economies in transition to meet specific emission reduction targets. The protocol recognizes that developed nations are primarily responsible for the high levels of greenhouse gases in the atmosphere due to their historical industrial activities. Under the Protocole de Kyoto, participating countries can use various mechanisms, such as emissions trading and the Clean Development Mechanism, to meet their targets. The agreement emphasizes the importance of global cooperation in addressing climate change and encourages nations to adopt sustainable practices to protect the environment.
