Ozone Layer Depletion
Earth's atmosphere is divided into three
regions, namely troposphere, stratosphere, andmesosphere. The stratosphere extends from 10 to 50kms from the Earths surface.
Ozone is produced and destroyed naturally in the
atmosphere and until recently, this resulted in a well-balanced equilibrium.

Ozone Depletion Process
Ozone is highly reactive and easily broken
down by man made chlorine and brominecompounds. These compounds are found to be mostresponsible for most of ozone layer depletion.

Chemistry of ozone depletionChemical equation is
CFCI3+UV Light=> CFCI2+CICI+O3=> CIO+O2
CIO+O3=> CI+O2
The free chlorine atom is then free to attack another
ozone moleculeCI+O3=> CIO+O2
CIO+O3=> CI+O2
And again same..

Global Warming
The key greenhouse gases (GHG) causing
global warming is carbon dioxide. Over the last 100years, it was found out that the earth is getting warmerand warmer, unlike previous 8000 years whentemperatures have been relatively constant. The
present temperature is 0.3-0.6*C warmer than it was100 yeas ago.

Global Warming Potentials
GWPs measure the influence greenhouse
gases have on the natural greenhouse effect, includingthe ability of greenhouse gas molecules to absorb ortrap heat and the length of time, greenhouse gasmolecules remain in the atmosphere before being
removed or broken down.

Global warming (Climate Change)
Implicationsy Rise in global temperature: Temperature is risen by
about 0.6*C over the 20th centaury. It will rise by about
6*C by the year 2100.y Rise in sea level: The mean sea level is expected 9 -
88 cm by the year 2100.
y Food shortage and hunger: Water resource will be
affected as precipitation and evaporation patternschange around the world.
y India could be more at risks than many othercountries.

Loss of Biodiversity
Biodiversity refers to the variety of life on
earth, and its biological diversity. It is now believedthat human activity is changing biodiversity andcausing massive extinctions. The word resourceinstitute reports that there is link between Biodiversity
and climate change.

Climate Change Problem and
Responsey The United Nations Framework Convention on
Climate Change, (UNFCCC) : In June 1992, the
UNFCCC was signed in Rio de Janeiro by over 150nations. The climate convention is the base forinternational co-operation within the climate changearea. In the convention the climate problems
seriousness is stressed. There is a concern that humanactivities are enhancing the greenhouse effect, whichcan have serious consequences on human settlementsand ecosystems.

The Kyoto Protocol
The 6 major greenhouse gases covered by the
protocol are :y Carbon dioxide (CO2)
y Methane (CH4)
y Nitrous oxide (N2O)
y Hydrofluoro carbons (HFCs)
y Perfluoro carbons (PFCs)
y Sulfur hexafluoride (SF6)

Emission Reductions
Overall emissions of such gases by at least
5% below 1990 levels in the commitment period 2008to 2012. The amounts for each country are listed as %of the year, 1990 and range from 92% ( a reduction of8% ) for most European countriesto 110% ( an in
crease of 10% ) for Iceland.
Developing countries Responsibilities.

Indias Greenhouse Gas Emissions
India has experienced a dramatic growth in fossil
fuel CO2 emissions, and the data compiled by variousagencies shows an increase of nearly 5.9% since 1950.At present India is rated as the 6th largest contributorof CO2 emissions behind China, the 2nd largest
contributor .

The Conference of the Parties
(COP)
The Conference of the Parties is the supreme body
of the Climate change convention. The vast majority ofthe words countries are members ( 185 as of July 2001).The convention entries into force for a country 90 daysafter that country ratifies it. The COP held its first
session in 1995 and will continue to meet annuallyunless decided otherwise.

The Flexible Mechanisms..y Emissions trading :
Article 17 of the Kyoto protocol opens up for
emissions trading between countries that have madecommitments to reduce greenhouse gas emissions.The countries have the option to delegate this rightof emissions trading to companies or other
organiz
ation.

The Flexible Mechanisms..y Joint implementation:
Under article 6 of the Kyoto protocol anannex 1 country that has made a commitment forreducing greenhouse gases, can offer to, or obtainfrom another annex 1 country greenhouse gas
emissions reductions.

The Flexible Mechanisms..y CleanDevelopment Mechanism (CDM)
Article 12 of the Kyoto Protocol defines the Clean
Development mechanism, CDM. The purpose of CDMis to:
a. Contribute to sustainable development indeveloping countries;
b. Help Annex 1-coutries under the Kyoto Protocol tomeet their target.

Prototype Carbon Fund (PCF)
Recognizing that global warming will have the
most impact on its borrowing client countries, theWorld Bank approved the establishment of thePrototype Carbon Fund (PCF). The PCF is intended toinvest in projects that will produce high quality
greenhouse gas emissions reductions that could beregistered with the UNFCCC for the purposes of theKyoto Protocol.

Sustainable DevelopmentWhat is SustainableDevelopment?
Sustainable Development is often defined as development that meets the needs of the present,without compromising the ability of futuregenerations to meet their own needs.
Sustainable Development encompasses three basic andinter-related objectives:
y Economic security and prosperityy Social development and advancement
y Environmental sustainability
