In October 2022, the USAID Bureau for Humanitarian Affairs (BHA) published an additional resource on Environmental Sustainability in Humanitarian Supply Chain which provides important notes, implementation timeline, list of suggested concrete measures, sample checklist/self-assessment tool, and additional resources to be used by partners applying for emergency funding.  The resource (not required) is in addition to Section 12.13 Supply Chain Requirements listed in BHA’s Emergency Application Guidelines (required).
