The study is also the first ever to show how the 1.5°C target can be reached without relying on unproven technologies such as bioenergy with carbon capture and storage (CCS) which remove carbon dioxide from the atmosphere and bury it.

Arnulf Grubler, lead author of the study and IIASA acting program director, says, "Our analysis shows how a range of new social, behavioral and technological innovations, combined with strong policy support for energy efficiency and low-carbon development, can help reverse the historical trajectory of ever-rising energy demand."
