In a 227-page report, the International Energy Agency said it is possible to achieve net-zero emissions by 2050 and limit warming to 1.5 C. But it will require a wholesale makeover of the world’s energy system starting today. Dramatic action is required in the next decade to have any hope achieving a net-zero goal by 2050, IEA said. Many analysts question whether it is possible to limit warming to 1.5 C by 2100 (Climatewire, June 5, 2020). Heavy reliance on negative emissions technologies was a staple of many 1.5 C pathways modeled by the IPCC (Climatewire, Dec. 22, 2020). “The report makes it clear that the window to get to net-zero emissions by 2050 is narrow, but—and this important—still achievable,” said Costa Samaras, a professor who studies energy systems at Carnegie Mellon University.
