• Climate stabilization has substantial GDP costs, but effects on welfare are limited;
• Co-benefits to climate stabilization offset many of its costs;
• Benefits from avoided climate damage and co-benefits strongly outweigh decarbonization costs;
• Climate goals to date reflect mitigation levels that are economically suboptimal;
• Climate stabilization will cost much more if implementing a stringent global climate agreement is delayed;
• A global market for greenhouse gas emissions could benefit Southeast Asia;
• Emission reductions are driven by land use, energy efficiency, and low-carbon energy sources;
• Avoided deforestation is critical to reduce decarbonization costs in the short to medium term;
• Low-carbon energy technologies are critical to reduce decarbonization costs in the long term;
• Early action on advanced energy technologies is needed to enable their mitigation potential;
• Further energy efficiency improvements are essential for cost-effective emission reduction;
• Green infrastructure investments can facilitate low-carbon transitions;
• Climate stabilization can cost less than what the region has spent on energy subsidies; and
• International assistance can help to achieve global climate stabilization goals.
