Book excerpt: This report explores what a global transition to net zero could mean for Asia and the Pacific under a range of climate policy scenarios and provides recommendations. Developing Asia faces a climate policy crossroads. The region is highly vulnerable to climate change, even as it is an increasing contributor to the global climate crisis. This report models emission pathways based on commitments and pledges under the Paris Agreement and compares them with more optimal routes to net zero. It examines required transformations in the energy sector and land use and assesses socioeconomic implications. The report looks at policy costs, climate benefits, air quality co-benefits, and labor market outcomes, and discusses policies for an efficient and equitable transition.
