Environmental Events Chronological Order

This question asks to arrange significant environmental conferences and protocols in chronological order based on their year of enactment or occurrence, starting from the oldest to the most recent. Understanding the timeline of these key international environmental agreements is crucial for studying global environmental policy and history.

Key Environmental Agreements Years for Chronological Order

To arrange these in chronological order, we need to know the specific years these events took place or were enacted:

• E. Tbilisi Conference: Held in 1977, focusing on environmental education.
• B. Montreal Protocol: Signed in 1987, aimed at phasing out ozone-depleting substances.
• A. Basel Convention: Adopted in 1989, controlling transboundary movements of hazardous wastes and their disposal.
• D. Kyoto Protocol: Adopted in 1997, committing to reducing greenhouse gas emissions.
• C. Copenhagen Summit: The 15th Conference of the Parties (COP15) to the UNFCCC, held in 2009.

Correct Chronological Order Sequence Determination

Arranging these events based on their years from oldest to most recent:

1977 (E) < 1987 (B) < 1989 (A) < 1997 (D) < 2009 (C)

This leads to the chronological sequence: E, B, A, D, C.

This order accurately reflects the timeline of these important environmental milestones.
