  • Stockholm Declaration, 1972: United Nations Conference on Human Environment gave this declaration & its document was composed of 7 proclamations & 26 principles to guide people to preserve & enhance human environment.

  • Belgrade Charter, 1975: It was the result of International Workshop on Environmental Education at Belgrade, Yugoslavia & was based on Stockholm Declaration. It added goals, objectives, & guiding principles for environmental education & defined audiences.

  • Tbilisi Declaration, 1977: Intergovernmental Conference on Environmental Education in Tbilisi, Georgia gave this declaration & highlighted importance of environmental education to conserve & improve world’s environment & balanced development of the world’s communities. It was an updated version of Stockholm Declaration & Belgrade Charter.

  • 1972’s United Nations Conference on the Human Environment. Refer Stockholm declaration.

  • 1983’s World Commission on Environment & Development or Brundtland Commission to address need to accelerate deterioration of human environment & natural resources, & its consequences for economic & social development.

  • 1992’s United Nations Conference on Environment & Development (UNCED or Rio Summit, Rio Conference, or Earth Summit)

  • 2002’s World Summit on Sustainable Development.

  • Volcano

  • Earthquake

  • Plate tectonics

  • Tsunami

  • Cyclone

  • Indoor Pollution

  • Soil Erosion

  • Deforestation

  • Climate change

  • Ozone depletion

  • Greenhouse effect and global warming

  • Biodiversity: Reduction & conservation

  • Kyoto Protocol

  • Ozone – Formation, Destruction

  • Cause

  • Consequence

  • Montreal Protocol

  • IUCN Classification

  • In-Situ & Ex-Situ

  • Species Conservation

  • Emissions Trading: It is also called “carbon market” & aims to control pollution by giving economic incentives to achieve reductions in pollutants emissions & is a form of carbon pricing.

  • Clean Development Mechanism (CDM): It is one of the flexibility mechanisms where “Annex I” parties are industrialized countries while Non-Annex I parties are developing countries. Annex I nations have binding GHG emissions targets. This mechanism intends to meet two objectives:

    • To assist non-Annex I parties to achieve sustainable development & to contribute to final objective of UN Framework Convention on Climate Change (UNFCCC), which aims to prevent dangerous climate change.

    • To assist Annex I parties to achieve compliance with GHG emission caps i.e., their quantified emission limitation & reduction commitments.

  • Joint Implementation (JI): It helps Annex I nations to meet their obligations. Any Annex I nation can invest in emission reduction projects (Joint Implementation Projects) in any other Annex I nation as an alternative to decrease emissions domestically.

  • European community in 1989 proposed complete ban on the use of in 1990’s.

  • In December 1995, more than 100 nations decided to phase out production of the pesticide methyl bromide, which led to 15% of ozone depletion by year 2000.

National Action Plan on Climate Change

8 govt missions under National Action Plan on Climate Change (NAPCC)

  • National Solar Mission

    This initiative started in 2010 to promote the use of solar power.

    Recently, in January this year, India achieved 20 gw (giga watt) cumulative solar capacity -- achieving the milestone four years ahead of the target for 2022 originally set in the National Solar Mission.

  • National Mission for Enhanced Energy Efficiency

    • The initiative was undertaken to promote the market for energy efficiency by fostering innovative policies and effective market instruments.

    • In 2009, it was approved ‘in principle’ by the PM’s Council on Climate Change.

  • National Mission on Sustainable Habitat

    • Approved by the PM in 2011, it aims to make cities sustainable through improvements in energy efficiency in buildings, management of solid waste and shift to public transport.

    • The Ministry of Housing and Urban Affairs backs the mission.

  • National Water Mission

    • The mission was put in place to ensure integrated water resource management helping to conserve water, minimize wastage and ensure more equitable distribution both across and within states.

    • This mission is one of the most proactive ones and is backed by the National Water Policy as well as the Ministry of Water Resources, River Development and Ganga Rejuvenation.

  • National Mission for Sustaining the Himalayan Ecosystem

    • A multi-pronged, cross-cutting mission across various sectors, in 2014.

    • Aimed at protecting the Himalayas, it has mapped institutes and civil society organisations working on the Himalayan ecology for ease of coordination between governmental and non-governmental agencies.

  • National Mission for a Green India

    • Also termed as the Green India Mission/Scheme, it aims at protecting; restoring and enhancing India’s diminishing forest cover and responding to climate change by a combination of adaptation and mitigation measures.

    • Driven by the Ministry of Environment and Forests, it received the nod of approval from the Cabinet in 2014.

  • National Mission for Sustainable Agriculture

    • Another one of the govt’s most efficient missions, it has been formulated for enhancing agricultural productivity especially in rain-fed areas focusing on integrated farming, water use efficiency, soil health management and synergizing resource conservation.

    • Livestock-based farming systems to create sustainable livelihoods in drought prone districts of Andhra Pradesh. (Image: National Mission for Sustainable Agriculture website)

    • It got the nod back in 2010, and has recently got approval for one of its key missions -- National bamboo mission -- by the Cabinet.

National Mission on Strategic Knowledge for Climate Change

  • The mission seeks to build a dynamic and vibrant knowledge system that informs and supports national policy and action for responding effectively to climate change challenges, while not compromising on the nation’s growth goals.

  • Department of Science and Technology drives the mission, and a recent development under the mission was the govt’s approval for establishing Karnataka’s first climate change lab.

    • Power Generation: The government is mandating the retirement of inefficient coal-fired power plants and supporting the research and development of IGCC and supercritical technologies.

    • Renewable Energy: Under the Electricity Act 2003 and the National Tariff Policy 2006, the central and the state electricity regulatory commissions must purchase a certain percentage of grid-based power from renewable sources.

    • Energy Efficiency: Under the Energy Conservation Act 2001, large energy-consuming industries are required to undertake energy audits and an energy labelling program for appliances has been introduced.

  • International Solar Alliance

  • Global Solar Atlas

  • KUSUM (Kisan Urja Suraksha Evam Utthaan Mahaabhiyan)

  • International Renewable Energy Alliance

  • The International Solar Alliance (ISA) is an alliance of more than 121 countries initiated by India, most of them located between the Tropics of Cancer and Capricorn.

  • The aim of ISA is to have 1000 GW (or 1 TW) solar power capacity by 2030 that is triple the amount of solar energy in entire world. This would require $1 trillion.

  • National Institute of Solar Energy (NISE) in Gwal Pahari, Gurugram with 5-acre land would be the headquarters of ISA in India
