Difficulty: MediumClimate Change, Global Warming and Ozone Layer Depletion

Match the environmental protocols and conventions in List-I with their primary objectives or key provisions in List-II:

  • Montreal ProtocolPhase-out of ozone-depleting substances such as chlorofluorocarbons (CFCs)
  • Kyoto ProtocolBinding emission reduction targets for developed nations on greenhouse gases
  • Kigali AmendmentPhase-down of the production and consumption of hydrofluorocarbons (HFCs)
  • Vienna ConventionFramework agreement establishing international cooperation to protect the ozone layer

Answer

Montreal Protocol matches with phase-out of ozone-depleting substances such as CFCs; Kyoto Protocol matches with binding emission reduction targets for developed nations on greenhouse gases; Kigali Amendment matches with phase-down of the production and consumption of HFCs; Vienna Convention matches with framework agreement establishing international cooperation to protect the ozone layer.
The Montreal Protocol focuses on phasing out ozone-depleting substances like CFCs. The Kyoto Protocol establishes binding greenhouse gas emission reduction commitments. The Kigali Amendment targets the phase-down of potent greenhouse gas HFCs. The Vienna Convention serves as the overarching framework for international ozone layer protection.

Step-by-Step Solution

1
Identify the primary mechanism of the Montreal Protocol.
It establishes legally binding timelines to eliminate ozone-depleting substances like chlorofluorocarbons (CFCs).
The treaty specifically targeted substances responsible for creating the Antarctic ozone hole.
2
Identify the legal structure of the Kyoto Protocol.
It imposed targeted emission cuts on Annex I (developed) nations for six key greenhouse gases.
Adopted under UNFCCC in 1997, it operationalized international commitment against global warming.
3
Determine the focus of the Kigali Amendment.
It extends the Montreal Protocol to phase down hydrofluorocarbons (HFCs).
Though non-ozone depleting, HFCs possess global warming potentials thousands of times higher than carbon dioxide.
4
Associate the Vienna Convention with its foundational regulatory role.
It established non-binding global framework mechanisms and research sharing regarding the ozone layer.
Adopted in 1985, it laid the framework before concrete phase-out targets were codified under Montreal.

Key Concept

Key international climate change conventions, ozone protection agreements, and greenhouse gas control instruments.
