Explanation:

Kyoto conference is connected with limiting production of CO2 and other green house gases and developing alternatives to ODS (Ozone Depleting Substance).
Or we can say that the Kyoto Protocol is an international treaty which extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits State Parties to reduce greenhouse gas emissions, based on the scientific consensus that (a) global warming is occurring and (b) it is extremely likely that human-made CO2 emissions have predominantly caused it.
