Unit 10: Environmental Policies & Global Conventions
1. Need for International Agreements
Environmental problems like Global Warming and Ozone Depletion do not recognize national borders. A pollutant released in one country can affect the climate of another. Therefore, global cooperation is essential.
2. Major International Protocols
These are legally binding agreements designed to address specific environmental crises.
Montreal Protocol (1987):
Focused on phasing out the production of CFCs (Chlorofluorocarbons) and other substances that deplete the Ozone Layer. It is considered the most successful environmental treaty to date.
Kyoto Protocol (1997):
The first international agreement to set binding targets for industrialized countries to reduce Greenhouse Gas (GHG) emissions. It introduced "Carbon Credits."
3. Earth Summits and Global Forums
- Stockholm Conference (1972): The first major UN conference on international environmental issues. It led to the creation of UNEP (United Nations Environment Programme).
- Rio Earth Summit (1992): Produced "Agenda 21" (a blueprint for sustainable development) and the Convention on Biological Diversity (CBD).
4. Sustainable Development Goals (SDGs)
In 2015, the UN adopted 17 Sustainable Development Goals to be achieved by 2030. They integrate social, economic, and environmental targets.
- Goal 7: Affordable and Clean Energy.
- Goal 13: Climate Action.
- Goal 14 & 15: Life Below Water and Life on Land.
5. The Paris Agreement (2015)
The successor to the Kyoto Protocol. Its goal is to limit global warming to well below 2°C, preferably to 1.5°C, compared to pre-industrial levels.
- NDCs: Each country sets its own "Nationally Determined Contributions" to reduce emissions.
- Global Stocktake: A mechanism to review progress every five years.
6. Exam Focus Enhancements
Exam Tips
- The "Success" Case: Always use the Montreal Protocol as an example of successful international policy.
- Carbon Credits: Briefly explain this concept—if a country emits less than its limit, it can "sell" its remaining quota to another country.
- 2030 Deadline: Mention the 2030 target when discussing SDGs; examiners love temporal precision.
Common Mistakes
- CFCs vs CO2: Students often say the Montreal Protocol was for CO2. No, it was for **CFCs** (Ozone). Kyoto/Paris were for **CO2** (Climate).
- Binding vs. Non-binding: Remember that while the Paris Agreement has universal participation, the emission targets themselves are *voluntary* (NDCs), unlike the strict Kyoto targets.
- Stockholm Year: Don't forget 1972—the birth of modern environmental policy.
Frequently Asked Questions

A: The United Nations Environment Programme, based in Nairobi, Kenya. It coordinates UN environmental activities.
Q: What does "Net Zero" mean?
