Natural vs Enhanced Greenhouse Effect — Environmental Laws

Entry	Year	Description	Impact
N/A (International Treaty)	1997 (adopted), 2005 (entered into force)	The Kyoto Protocol was an international treaty that committed industrialized countries to legally binding emission reduction targets for greenhouse gases. It operationalized the UNFCCC and established mechanisms like emissions trading, the Clean Development Mechanism (CDM), and Joint Implementation (JI).	Represented the first legally binding international effort to curb anthropogenic GHG emissions. While limited in scope (only developed countries had targets), it laid the groundwork for future climate agreements and introduced market-based mechanisms for emission reduction. India, as a developing country, did not have emission reduction targets under the Protocol.
N/A (International Treaty)	2015 (adopted), 2016 (entered into force)	The Paris Agreement is a legally binding international treaty on climate change. Its goal is to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels. It requires all parties to put forward Nationally Determined Contributions (NDCs) outlining their climate action plans, shifting from a top-down to a bottom-up approach.	A landmark agreement that brought all nations into a common cause to undertake ambitious efforts to combat climate change and adapt to its effects. It significantly strengthened the global response to the enhanced greenhouse effect by establishing a universal framework and a long-term temperature goal, influencing national climate policies and investments globally, including India's updated NDCs.
N/A (National Policy Framework)	2008	India's National Action Plan on Climate Change (NAPCC) outlines a national strategy to address climate change, focusing on both adaptation and mitigation. It comprises eight national missions (e.g., National Solar Mission, National Mission for Enhanced Energy Efficiency) aimed at promoting sustainable development while addressing climate change challenges.	Provided a comprehensive domestic framework for India's climate action, guiding policy and investment in areas like renewable energy, water conservation, sustainable agriculture, and forest cover. It demonstrates India's commitment to tackling the enhanced greenhouse effect through a multi-sectoral approach, balancing developmental needs with environmental protection.
