COP negotiations and Malaysian climate change roadmap: a comparative assessment using a dynamic environmental model

Area of Science:

• Climate change economics
• Environmental policy analysis
• Economic modeling for climate action

Background:

• Malaysia faces significant climate damage costs.
• International climate change agreements (COP21, COP22) offer potential solutions.
• Evaluating local climate roadmaps is crucial for effective policy.

Purpose of the Study:

• To critically evaluate two COP proposals for Malaysia's climate damage reduction.
• To assess the economic implications of different climate action scenarios.
• To inform policymakers on the most effective climate strategy for Malaysia.

Main Methods:

• Utilized a top-down disaggregation framework.
• Employed the "Empirical Regional Downscaling Dynamic Integrated Model of Climate and the Economy" (EDMClimate).
• Evaluated local government climate roadmaps and national emissions reduction agendas.

Main Results:

• Climate damage costs from 2010-2110 are projected at MYR5,483 billion (Malaysian Optimal Climate Action) vs. MYR5,264 billion (COP21/COP22).
• The COP22 time-adjusted COP21 proposal is identified as more effective for reducing climate damage.
• Significant macroeconomic cost implications for savings and consumption were identified.

Conclusions:

• The COP22 proposal offers a more effective pathway for climate damage reduction in Malaysia.
• Policy implementation requires careful consideration of macroeconomic impacts on savings and consumption.
• Further analysis is needed to address these economic trade-offs before policy enactment.
