The objective of this document is to recommend improvements to the existing guidance on technology needs assessment (TNA), technology action plans (TAPs) and project ideas for the enhanced implementation of priority technologies for development and climate change mitigation and adaptation. It reviews: existing non-TNA guidance for preparing prioritized technology options for implementation; existing guidance within the global TNA project for formulating TAPs and project ideas for implementation; and TAPs and project ideas within the global TNA project with a specific focus on the extent to which these contain the information that is required for preparing for implementation.
