Given the rapid pace of action in the United States and other leading countries, if other major economies adopt similar levels of ambition, the world can keep a safer 1.5°C future within reach. For its part, the United States currently emits 11% of annual global GHGs (second to China, which emits 27% of the global total), so eliminating U.S. emissions by 2050 will make an important direct contribution to reaching our shared global climate goals. However, others must step up with both long-term and short-term ambition, and many are already doing so. To date, at least 63 countries representing over half current global emissions have committed to net-zero GHG emissions targets. Many more, representing over 70% of global emissions, are in With our ambitious NDC target to cut emissions in half or more by 2030, and our goal for net-zero emissions no later than 2050, the United States has committed to sustained investment in a vibrant clean economy that will propel global climate action while improving social, economic, and health equity at home. with lower climate footprints. And we can develop, train, and educate workers for productive and healthier work in new and fast-growing industries. Undoubtedly, the U.S. roadmap will evolve as we learn more about the potential for new technologies in diverse applications, and as new policy platforms are developed over time. The United States intends to regularly review and update this Long-Term Strategy as needed to consider such developments and the latest science.
