Sustainable Development — Environmental Laws

Entry	Year	Description	Impact
42nd Amendment Act	1976	This landmark amendment, often called the 'Mini-Constitution,' introduced significant changes to the Indian Constitution, including the insertion of Article 48A and Article 51A(g).	It provided a constitutional mandate for environmental protection, making it a Directive Principle of State Policy (Article 48A) and a Fundamental Duty of citizens (Article 51A(g)). This laid the legal and ethical groundwork for subsequent environmental legislation and policy, directly influencing India's approach to sustainable development by embedding environmental concerns within the constitutional framework.
