The Kyoto Protocol is a legally binding international agreement adopted in 1997 under the United Nations Framework Convention on Climate Change (UNFCCC) to address global warming by reducing greenhouse gas (GHG) emissions. It entered into force on February 16, 2005, after a sufficient number of countries ratified it, meeting the dual requirement of ratification by at least 55 Parties accounting for 55% of global emissions.
The protocol operationalised the principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC) by placing binding emission reduction targets only on developed countries (Annex I Parties). For the first commitment period (2008-2012), Annex I countries committed to reduce emissions by an average of 5% below 1990 levels.
To provide flexibility and cost-effectiveness, the Kyoto Protocol introduced three market-based mechanisms:
1. Clean Development Mechanism (CDM) – allowed developed countries to earn carbon credits by funding emission-reduction projects in developing countries.
2. Joint Implementation (JI) – enabled Annex I countries to undertake projects in other Annex I nations.
3. International Emissions Trading (IET) – permitted trading of emission allowances among developed countries.
India, though a non-Annex I country, benefited significantly from the CDM, attracting investment in renewable energy and energy efficiency projects. The United States signed but never ratified the protocol, while Canada withdrew in 2011.
Although criticised for limited coverage and enforcement, the Kyoto Protocol was a foundational step in global climate governance, paving the way for the Paris Agreement (2015), which expanded climate action to all countries.
For UPSC, Kyoto Protocol is relevant under international environmental agreements, climate diplomacy, carbon markets, CBDR and India’s role in global climate regimes.
