Q.Discuss the major international and national (Indian) policy responses to environmental degradation and climate change.

Policy responses operate at two connected levels — global agreements setting shared goals and obligations, and domestic law and economic instruments that translate those goals into enforceable national action.

Policy responses to environmental degradation and climate change operate at two connected levels: international agreements that establish shared global goals and obligations, and domestic law and economic instruments that give those goals legal and practical force within a country.

International responses.

1. Stockholm Conference, 1972 — the UN Conference on the Human Environment was the first major global forum to formally recognise the link between economic development and environmental protection, prompting many countries, including India, to establish dedicated environmental ministries and pollution-control institutions in the years that followed.
2. Rio Earth Summit, 1992 — the UN Conference on Environment and Development in Rio de Janeiro adopted the Rio Declaration and Agenda 21 (a detailed sustainable-development action plan) and opened for signature the UN Framework Convention on Climate Change (UNFCCC) and the Convention on Biological Diversity, the two treaties that still anchor global climate and biodiversity cooperation today.
3. Kyoto Protocol, 1997 — adopted under the UNFCCC, it imposed binding greenhouse-gas emission-reduction targets specifically on industrialised (developed) countries, reflecting the principle that nations responsible for the bulk of historical emissions should bear the first binding obligations.
4. Paris Agreement, 2015 — replaced Kyoto's developed-country-only approach with a universal framework in which every signatory, developed and developing alike, submits its own Nationally Determined Contributions (NDCs) toward a shared global temperature goal, reviewed and progressively strengthened over time.

India's domestic legal framework.

• The Water (Prevention and Control of Pollution) Act, 1974 and Air (Prevention and Control of Pollution) Act, 1981 established Pollution Control Boards at the central and state level, including the Andhra Pradesh Pollution Control Board, with authority to set and enforce quality standards.
• The Environment (Protection) Act, 1986, enacted in the aftermath of the 1984 Bhopal gas tragedy, is the umbrella law giving the central government wide powers to regulate hazardous substances, set standards and restrict industrial siting across every form of environmental harm.
• The Forest (Conservation) Act, 1980 and Wildlife Protection Act, 1972 protect forest land from unauthorised diversion and protect endangered species and habitats.
• The National Green Tribunal Act, 2010 created a specialised judicial body for the fast resolution of environmental disputes, outside the ordinary civil court system.

Economic (market-based) instruments, used alongside this regulatory framework, include Pigouvian pollution taxes (a tax equal to the marginal external cost, so the polluter's private cost matches the true social cost), tradable emission permits (a fixed total quota of allowed pollution, traded so the required reduction is achieved at the lowest overall cost), subsidies for clean and renewable technology, and extended producer-responsibility schemes for plastic and electronic waste. …

Students often list international treaties and Indian laws as two disconnected lists without noting how they relate — for instance, that Stockholm (1972) directly triggered India's own Water and Air Acts of the 1970s, or that the Paris Agreement's NDCs are implemented domestically t …
