Q4) (b)

Enlist the mitigation measures for climate change.

Some of the international step for mitigating global change are discussed below :

Montreal Protocol

  • In 1987, twenty seven, industrialized countries signed an international agreement to protect the ozone layer in stratosphere. This agreement is known as Montreal Protocol. The main points of the agreement are to limit the production and use of ozone depleting substances.
  • The participating countries agreed to freeze production of CFC at 1986 levels and to reduce production by 50% by 1999. In 1992 the phase out date for CFCs and halon entirely was moved up to 1996.
  • Helping the developing countries to implement use of alternatives to CFCs.
Up till now, more than 175 countries have signed the Montreal protocol.

Kyoto protocol

An international conference held in Kyoto, Japan in December, 1997, has specified the commitments of different countries to mitigate climate change. This protocol requires countries to take appropriate measures of to reduce their overall greenhouse emission to a level at least 5 per cent below the 1990 level by the Commitment period 2008-2012.

Earth summit

The United Nations conference on Environment and Development (UNCED), the Earth-summit, held at Rio de Janeiro, Brazil in 1992, established the principles for reducing greenhouse gas emission.
