The LEDS-Tool provides developers and implementers of Low Emission Development Strategies with brief step-by-step instructions on how to develop a LEDS. The tool navigates users to the relevant information, knowledge, instruments, and publications available. Low-Emission Development Strategies (LEDS) are national long-term strategies for reducing emissions while promoting sustainable development. They can provide an overall framework for the development of Nationally Appropriate Mitigation Actions (NAMAs). The LEDS-Tool guides practitioners step-by-step through the process of developing and implementing a LEDS. The process is structured into six steps. The 6-step approach is designed to lead users to more information about and accessible instruments for certain aspects of LEDS development.
