Global momentum is building to achieve net zero in greenhouse gas (GHG) emissions—and to do so more quickly than previously envisioned. Getting there will require unprecedented levels of innovation. Some estimates, such as the P4 pathway defined by the Intergovernmental Panel on Climate Change (IPCC), show that today’s technologies have the potential to reduce global emissions by about two-thirds. More innovation-driven projections—such as IPCC’s low-energy demand pathway, P1—do not bank on any new technologies but instead assume radical business model and policy innovation.
