Environment is the most essential element for life and protecting it, is the core of the Kyoto protocol. In simple terms, the importance of the Koyoto protocol is its efforts to slow down global warming by reducing the emission of greenhouse gases. Earlier protocols that negotiated on the issue, only made suggestions to the countries to implement the suggestions voluntarily. Koyoto protocol made it mandatory (legally binding) for the ratified countries to meet the target of reducing emissions by a set percentage by a set date.
Its scope may be limited, but it is a right step in the effort to influence climate change. It can serve as a learning ground and starting point for more elaborate and wide-scoped negotiations.
