Estimates suggest that up to 45% of the global emission reductions needed to get to net zero will be achieved through technologies that are not currently available. We need low- and zero-carbon technologies to be deployed across all sectors of the global economy that are cleaner, cheaper, more available, and more effective than what’s currently in the marketplace. Innovation of this scale requires a financial incentive to push clean energy ideas into labs, drive them to demonstration, and pull them into the marketplace. Only an economywide carbon price can do this at every stage of the invention-deployment continuum.
