Meeting the 1.5°C ambition: moving from incremental to exponential action

The second in its series, the 2019 Exponential Roadmap is complemented with a high-ambition narrative, Meeting the 1.5°C Ambition, that presents why the world must aim to hold global average temperature increase to just 1.5°C. Each new roadmap updates solutions that have proven potential to scale and charts progress towards exponential scaling, using exponential strategies needed to cut emissions 50 percent by 2030 or earlier, then doing it again by 2040 and again by 2050.
