2. Global Warming and Pollution
• Global Warming and pollution are
increasing globally
– Depletion of ozone layer.
– Pollution leading to global warming and
climate change
– Disposal of waste by dumping into sea
creates water pollution
– Air pollution by carbon emissions

4. Global carbon emissions
Global carbon emissions from fossil fuel use, from 1850-1990 and
as projected to 2100 - in billions of tonnes of carbon (GtC).MD Siyam Hossain

5. Global Warming and Pollution-
Risk at Glance
• More than 10 million people are at risk for lung
infection, cancer and shortened life expectancy
• 10 cities in eight countries where pollution poses
health risks and fosters poverty.
• 5.5 million people are still threatened by
radioactive material that continues to seep into
groundwater.

6. Consequences of Global Warming and
Pollution
• A small rise in temperatures can produce a 10-fold
increase in the mosquito population
• Because of thermal expansion of ocean water and
accelerated melting of glaciers, sea level is likely to rise
by about half a metre by 2100
• There will be more frequent and more intense floods or
droughts, especially in sub-trop-ical areas
• Impacts of global warming may be positive. For some
crops, increased carbon dioxide aids growth

7. Global Warming and Pollution
-A Challenge
• A challenge for everybody
• for governments, to set the necessary
framework,
• for business and industry, to seize the
opportunities for innovation and use of ‘clean’
technologies
• for scientists, to provide better information about
likely climate change and its various local
impacts,
• for all communities and individuals in the world,
to support the action being taken and contribute
to it.

8. Global Warming and Pollution-
The Role of U.S.
• The United States is the world's largest
emitter of greenhouse gases
• The Kyoto accord requires 35 industrial nations — not
including the U.S., which rejects the pact — to reduce
such emissions by an average 5 percent below 1990
levels by 2012.
• President Bush says such emissions cuts would harm
the U.S. economy and complains that poorer countries
also should be covered.
• Bush administration officials say they recognize the
problem and have plans in place to reduce greenhouse
gas emissions by 500 million metric tons by 2012.

9. Spillover costs
• Spillover Costs
- Negative effects of producing or
consuming a product on outsiders,
not market participants.
- Producers of products with
negative external effects focus on
private costs when making supply
decisions.
- Use of free goods or goods whose
prices do not reflect its value.
- Prices are insufficient to cover
both private and spillover costs.
- example: environmental damage
