1.INTRODUCTION

• The principal guilty agents greenhouse gases
• Before the Industrial Revolution No Problem
• After the Industrialisation Big amount of
  emissions.
• Effects
• The warming of the Earth
• The change in the rainfalls
• The seasons
• ...

3

• Two different climate changes
• Small changes
• Hard changes
• Ethical Implications

4
2.POLICIES

• 3 core components
• The Targets
• Scientific models
• Economic models
• The Instruments
• The International Structures

5
2.1 The Target

• Reducing the CO2 emissions
• 2 models
• Scientific models
• Reduce CO2 emissions to the pre-industrial levels
• Alternative take current emissions levels as the
  base line and hold it.
• Limits of the model

6

• Economic models
• Simulate the effects of climate change on the
  world ecomomy
• CO2 as a commodity
• Factors that are creating some impacts in
  marginal damage estimates( excatastrophic
  events,contingent effects...)

7
2.2 The Instruments

• Imposing a tax
• Emitting Permits
• A carbon tax might be the most efficient
  economic system to reduce CO2 emissions.But it
  also needs to overcome the political and
  institutional obstacles

8
2.3 The International Structures

• Kioto, Johannesburg
• Problem credibility of the countries

9
2.4 The social cost of carbon

• Two different techniques
• The Cost Benefit Approach (CBA)

10

• The Marginal Cost Approach

11
2.5 The mix of policy measures

• Elements
• Uncertainties
• Scientific
• Economic
• Irreversibility Resources, Technological Changes
  and Climate Change.
• Potentially large but low probability events.

12
ALTERNATIVES AND SUGGESTIONS

• Prevention of Climate Change
• Adaptation to Climate Change
• Treatment of uncertainties
• Valuation of Physical Impacts
• Consideration of Regional Impacts

13
CONCLUSIONS

• More restricted policies
• The citizens have to be more concious

Grow in a sustainable way
