Environmental Agreements Chronological Ordering

To arrange the international environmental agreements in chronological order, we need to identify the year each event took place:

• A. Stockholm Conference (UNCHE): Held in 1972. This was the first major UN conference on the global environment.
• C. Montreal Protocol: Signed in 1987. An international treaty designed to protect the ozone layer by phasing out the production of numerous substances responsible for ozone depletion.
• E. Earth Summit (UNCED): Held in Rio de Janeiro in 1992. Also known as the Rio Summit, it addressed other pressing environmental issues like desertification, deforestation, and climate change.
• D. Kyoto Protocol: Adopted in 1997. An international treaty that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring.
• B. Paris Agreement: Adopted in 2015. A landmark international accord aiming to combat climate change by limiting global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.

Determining Correct Chronological Sequence

Based on the dates:

• 1972: Stockholm Conference (A)
• 1987: Montreal Protocol (C)
• 1992: Earth Summit (E)
• 1997: Kyoto Protocol (D)
• 2015: Paris Agreement (B)

Therefore, the correct chronological order is A, C, E, D, B.
