What is the purpose of the Montreal Protocol?
To phase out the production and use of CFCs (chlorofluorocarbons).
When was the Montreal Protocol signed, and how many nations agreed to it?
Signed in 1987 by 182 nations.
Why are CFCs harmful to the environment?
CFCs destroy the ozone layer, allowing harmful UV rays to enter and increasing global temperatures.
What common products used to contain CFCs?
Aerosol cans, fire extinguishers, and air conditioners.
What are HCFCs and how do they differ from CFCs?
HCFCs (hydrochlorofluorocarbons) are similar to CFCs but destroy the ozone much more slowly.
Why are HCFCs considered only a temporary solution?
Because they still damage the ozone, just at a slower rate.
What was Canada’s plan regarding HCFCs by the year 2020?
Canada planned to ban HCFCs by 2020.
What is the main goal of the UNFCCC?
To stabilize greenhouse gas emissions caused by humans.
According to the UNFCCC, what must not be threatened while reducing emissions?
Food production and the economic interests of any nation.
What concept is emphasized by the UNFCCC to protect the environment and future generations?
Sustainable development.
What is an example of a sustainable development practice mentioned in the UNFCCC?
Tree planting to replace trees harvested for forestry.
What is the main goal of the Kyoto Protocol?
→ To reduce greenhouse gas emissions globally
How many countries signed the Kyoto Protocol, and what was the emission reduction target?
→ 160 countries signed, agreeing to reduce emissions by 5% by 2012.
Why did some countries resist signing the Kyoto Protocol?
Due to concerns about economic impact and national interests.
What are Emission Reduction Credits (ERCs)?
Credits earned for actions that help reduce greenhouse gas emissions.
How can a country earn Emission Reduction Credits (ERCs)?
By helping which types of countries reduce emissions?
→ By helping developing countries or economically struggling developed countries (due to war or disaster).
b. By doing what kind of environmental activities?
→ By using practices that remove CO₂, such as tree planting.
What is carbon dioxide sequestering?
A method of pumping CO₂ into the ground.
How does carbon dioxide sequestering help in reducing greenhouse gases?
It stores CO₂ underground instead of releasing it into the atmosphere.
What additional benefit does CO₂ sequestering provide when pumped underground?
It helps extract underground oil reserves before the CO₂ is sealed in the empty space.
