Long-Term Low Emission Development Strategies (LT-LEDS) are crucial frameworks that guide countries in aligning their developmental goals with the Paris Agreement's objective to limit global warming to well below 2°C. These strategies provide a roadmap for transitioning national economies towards sustainable, low-carbon models by mid-century, integrating climate action with economic and social planning. By doing so, LT-LEDS enhance investor confidence, promote technological innovation, and ensure that both current and future generations benefit from sustainable development, increased climate resilience, and reduced emissions. 

Recognizing the challenges in developing LT-LEDS—stemming from their voluntary nature, limited guidance, and a lack of examples from developing countries—this guide serves as an essential resource. It provides practical and concise, step-by-step guidance on designing LT-LEDS, which are crucial for mitigating and adapting to climate change while aligning with development objectives. The guide encapsulates key lessons from early experiences and showcases prominent examples from developing countries. It is designed to assist both newcomers initiating LT-LEDS and those with established strategies, acknowledging the diversity in government capacity, economic contexts, and political dynamics.
