Introduction:
Greenhouse gas emissions, which are primarily caused by human activities such as the burning of fossil fuels, deforestation, and industrial processes, are a major contributor to climate change. Countries around the world are taking steps to regulate greenhouse gas emissions to reduce the impact of climate change. This article aims to compare the legal frameworks for regulating greenhouse gas emissions in India and the USA. It will discuss the key laws, landmark judgments, and recommendations for improving the legal frameworks.

Legal Framework in India:
The legal framework for regulating greenhouse gas emissions in India is primarily based on the following laws:

1. The Air (Prevention and Control of Pollution) Act, 1981:
   This law aims to prevent and control air pollution in India. It empowers the central and state governments to regulate emissions from industries, vehicles, and other sources of pollution.
    
2. The Environment (Protection) Act, 1986:
   This law provides for the protection and improvement of the environment. It empowers the central government to take measures to prevent and control environmental pollution.
    
3. The National Action Plan on Climate Change, 2008:
   This plan outlines India's strategy to mitigate and adapt to the impacts of climate change. It includes eight missions, including the National Solar Mission, the National Mission for Enhanced Energy Efficiency, and the National Mission on Sustainable Habitat.
    
4. The National Green Tribunal Act, 2010:
   This law provides for the establishment of the National Green Tribunal (NGT), which is a specialized court that deals with environmental disputes. The NGT has the power to hear cases related to air and water pollution, climate change, and other environmental issues.
    

In addition to these laws, India has also ratified the Paris Agreement, which aims to limit global warming to below 2 degrees Celsius above pre-industrial levels.

Landmark Judgments:
There have been several landmark judgments in India related to greenhouse gas emissions and climate change.

Some of the key judgments are:

• Vellore Citizens Welfare Forum v. Union of India (1996):
  This case was related to the pollution caused by tanneries in the Vellore district of Tamil Nadu. The Supreme Court of India directed the closure of polluting tanneries and ordered the state government to take measures to prevent and control pollution.
  
   
• M.C. Mehta v. Union of India (1998):
  This case was related to the pollution caused by industries in the Taj Trapezium Zone, which includes the Taj Mahal. The Supreme Court of India directed the closure of polluting industries and ordered the state government to take measures to prevent and control pollution.
   
• Centre for Public Interest Litigation v. Union of India (2016):
  This case was related to the air pollution in Delhi. The Supreme Court of India directed the central and state governments to take measures to reduce air pollution, including banning the sale of diesel vehicles with engines larger than 2000cc.

Legal Framework in the USA:
The legal framework for regulating greenhouse gas emissions in the USA is primarily based on the following laws:

1. The Clean Air Act, 1963:
   This law aims to protect and improve air quality in the USA. It empowers the Environmental Protection Agency (EPA) to regulate emissions from sources such as vehicles, power plants, and factories.
    
2. The National Environmental Policy Act, 1970:
   This law requires federal agencies to consider the environmental impacts of their actions and to take measures to minimize those impacts.
    
3. The Energy Policy Act, 1992:
   This law aims to promote energy efficiency and renewable energy in the USA. It includes provisions related to energy conservation, alternative fuels, and renewable energy.
    
4. The Paris Agreement, 2015:
   This agreement aims to limit global warming to below 2 degrees Celsius above pre-industrial levels. The USA ratified the Paris Agreement in 2016, but withdrew from the agreement in 2020 under the Trump administration. The Biden administration has since rejoined the agreement.

Landmark Judgments:
There have been several landmark judgments in the USA related to greenhouse gas emissions and climate change.

Some of the key judgments are:
Massachusetts v. Environmental Protection Agency (2007):
This case was related to whether the EPA had the authority to regulate greenhouse gas emissions from vehicles under the Clean Air Act. The Supreme Court of the USA ruled that the EPA did have the authority to regulate greenhouse gas emissions.

American Electric Power Co. v. Connecticut (2011):
This case was related to whether states could sue power companies under federal common law for their contribution to global warming. The Supreme Court of the USA ruled that the Clean Air Act and EPA regulations preempted the state's claims.

Juliana v. United States (2016):
This case was brought by a group of young people who argued that the US government's actions to promote the use of fossil fuels had violated their constitutional rights to life, liberty, and property. The case is still ongoing and has yet to be resolved.

Comparative Analysis:
India and the USA have different legal frameworks for regulating greenhouse gas emissions. While India's legal framework is based on laws that aim to prevent and control pollution, the USA's legal framework is based on laws that aim to protect and improve air quality and promote energy efficiency and renewable energy. Both countries have ratified the Paris Agreement, but the USA withdrew from the agreement under the Trump administration and later rejoined under the Biden administration.
