Article 246 of the Indian Constitution empowers the Parliament to enact laws for the protection of the environment. This includes laws related to air, water, and land pollution, as well as the conservation of forests and wildlife.

Agriculture is not a concurrent subject under the Indian Constitution. It is a state subject, which means that the state governments have the primary responsibility for enacting laws and policies related to agriculture.

Cooperative federalism is a key principle of federalism in India. It emphasizes the need for cooperation and coordination between the central and state governments in order to achieve common goals. This principle is reflected in the various mechanisms for intergovernmental cooperation, such as the Inter-State Council and the National Development Council.

The implementation of the National Environment Policy by the state governments is an example of cooperative federalism in India. It demonstrates the cooperation between the central and state governments in achieving a common goal, which is the protection of the environment.

The lack of cooperation between the central and state governments is a key challenge to federalism in India. This can lead to conflicts and disputes between the two levels of government, which can hinder the effective implementation of environmental laws and policies.

The establishment of the Central Pollution Control Board is an example of the overlapping of powers between the central and state governments in India. Both the central and state governments have the power to establish pollution control boards, which can lead to conflicts and disputes between the two levels of government.

All of the above factors contribute to the lack of financial resources at the state level in India. The high level of poverty means that the states have less revenue to spend on environmental protection. The large size of the Indian population means that the states have to provide a wide range of services, which can strain their budgets. The lack of economic development in some states means that they have less revenue to generate.

All of the above factors contribute to the lack of political will to implement environmental laws in India. The influence of powerful industries can lead to politicians being reluctant to take action that could harm those industries. The lack of public awareness about environmental issues can make it difficult for politicians to justify taking action on those issues. The lack of political leadership on environmental issues can also make it difficult to build public support for environmental protection.

The establishment of a National Environment Commission is a key recommendation of the Sarkaria Commission on Centre-State Relations. The Commission recommended that the National Environment Commission be established to advise the central government on environmental issues and to coordinate the activities of the central and state governments in the field of environmental protection.

The creation of a National Green Tribunal is a key recommendation of the Punchhi Commission on Centre-State Relations. The Commission recommended that the National Green Tribunal be established to adjudicate environmental disputes and to enforce environmental laws.

The enactment of a National Environment Act is a key provision of the National Environment Policy. The Act would provide a comprehensive framework for environmental protection in India and would address issues such as air pollution, water pollution, and land pollution.

All of the above are key provisions of the National Environment Act. The Act establishes a National Environment Commission, creates a National Green Tribunal, and establishes a Central Pollution Control Board. These institutions are all responsible for implementing and enforcing environmental laws and policies in India.

All of the above are key challenges to the effective implementation of environmental laws and policies in India. The lack of cooperation between the central and state governments, the overlapping of powers between the central and state governments, the lack of financial resources at the state level, and the lack of political will to implement environmental laws all make it difficult to effectively protect the environment in India.

The creation of a National Green Tribunal is a key recommendation of the Supreme Court of India for the effective implementation of environmental laws and policies. The Supreme Court has held that the National Green Tribunal is necessary to provide a specialized forum for the adjudication of environmental disputes and to ensure the effective enforcement of environmental laws.

The enactment of a National Environment Act is a key recommendation of the Law Commission of India for the effective implementation of environmental laws and policies. The Law Commission has held that the National Environment Act is necessary to provide a comprehensive framework for environmental protection in India and to address issues such as air pollution, water pollution, and land pollution.
