2. SCALE OF IMPACT Scale  is defined as a system or series of marks used for measuring or registering. Impact is measured according to their level of extent Sequence of numbers or words which only serve to identify certain entities or observations and have no quantitative significance

3. SCALE OF IMPACT -types

4. SCALE OF IMPACT - example DEFORESTATION

5. SCALE OF IMPACT - example

6. SCALE OF IMPACT

7. Global pollutants Pollutants which causes global impacts Far away from place of generation

8. Local pollutants Pollutants which causes local impacts

9. Global & local pollutants A typical example is the use of fossil fuels in energy-intensive industries, such as cement, glass, ceramics, paper and pulp, and metal casting industries. The combustion of fossil fuels not only generates green house gases such as carbon dioxide, methane and nitrousoxide , but also generates air pollutants with more localized effects, such as sulfurdioxide , volatile organic compounds and particulate matter. While local pollutants are subject to domestic environmental regulations,globalpollutantsmayberegulatedthroughdomesticallyadministeredregimes(e.g., national carbon taxes or domestic carbon emission permit markets) or, through certain international arrangement. With the entry into force of the Kyoto Protocol, international efforts are being made to set up a global carbon dioxide emission permit market to reduce green house gas emissions
