Even the most optimistic estimate of global emission reductions that will be achieved through implementation of the Intended Nationally Determined Contributions (INDC) is far below what is needed by 2030 to avoid dangerous climate change2 . While the global deal reached in Paris is critical, it is essential to look elsewhere for opportunities to close the gap. The innovation and leadership of subnational governments may be the best place to start. In this report, we provide a preliminary estimate of the potential contribution of the Under 2 MOU, a memorandum of understanding between sub-national governments to lower GHG emissions 80-95% below baseline levels or keep their emissions under 2 metric tons per capita by 2050.
