1) Reaching net-zero emissions requires addressing emissions from existing long-lived energy infrastructure like coal power plants and heavy industries, which make up the majority of emissions in emerging Asia. 2) Technologies that are currently only at prototype or demonstration stage contribute nearly 35% of emissions reductions needed by 2070 to reach net-zero, and innovations not yet adopted contribute another 40%. 3) Rapidly commercializing new technologies could allow the world to reach net-zero by 2050, but lack of policy support could delay achieving net-zero emissions.
