There are two meanings for the acronym REDD+, which are related but different. Concept 1 REDD+ covers public policies aimed at reducing emissions from deforestation and forest degradation, conservation, sustainable forest management and enhancement of forest carbon stocks. So when we talk about "REDD+ results" or "REDD+ activities", we refer to Concept 1. 
Concept 2 REDD+ refers to the international architecture designed to provide positive incentives to developing countries that demonstrate positive outcomes from their policies for REDD+ (Concept 1) under the United Nations Framework Convention on Climate Change (UNFCCC) legal structure.  In expressions like "Warsaw Framework for REDD+" or "REDD+ negotiations", the meaning of the acronym is related to Concept 2, the international architecture of results-based payments for REDD+. REDD+ in the UNFCCC REDD+ is a mechanism to provide positive incentives developed under the UNFCCC to reward developing countries for their results in combating deforestation and forest degradation and in increasing forest covered area. Under this mechanism, developing countries that deliver a reduction in greenhouse gases emissions from deforestation or forest degradation and/ or an increase in forest carbon stocks become eligible to receive results-based payments. Such results must be verified by international experts appointed by the UNFCCC Secretariat. Payments will be made through various international sources, especially through the Green Climate Fund (GCF).
Architecture of incentives The rationale behind REDD+ is to pay for results already achieved. Unlike the nested approach, REDD+ is national and the results presented are the responsibility of the Parties.
Elements required for recognizing REDD+ efforts 1. A national strategy or action plan;   2. A national forest reference emission levels and/or forest reference levels (or, if appropriate, as an interim measure, the corresponding sub-national levels); 3. A robust and transparent national forest monitoring system to monitor and report on REDD+ activities (with, if appropriate, subnational monitoring and reporting as an interim measure); 4. A system to provide information on how the safeguards are being addressed and respected throughout the implementation of REDD+ activities, taking national sovereignty into account.  
National REDD+ Strategy required components 1 Drivers of deforestation and forest degradation; 2 Land tenure issues; 3 Forest governance issues; 4 Gender considerations and safeguards.
