This research study is the first of its kind to estimate the potential impact of increased resources available to improve RMNCAH-N outcomes, from expanding and scaling up GFF support in 50 high-burden countries. The study estimates GFF impact by reflecting on conservative and ambitious assumptions based on the GFF Trust Fund resources of US$2.6 billion. Models are also scaled up by coverage prioritized by RMNCAH-N interventions under the resource scenarios in order to evaluate the period of 2017-2030. The results of the study revealed that the GFF partnership could collectively mobilize US$50-75 billion of additional funds to reach coverage of at least 70% for most interventions by 2030. This could result in averting over 34 million deaths compared with just over 12 million deaths averted with flatlined coverage following historic trends.
